1.2 --- ResponsibilityLiebert Hiross accepts no present or future responsibility fordamage to persons, things or to themachine itself due toopera-tors� negligence, failing tocomplywith the installation, operationand maintenance instructions of this handbook, failed applica-tion of the safety norms in force for the system and the qualifiedstaff charged with the operation and maintenance.

1.3 --- InspectionAll units are fully assembled and wired in the manufacturingplant. Before shipment they are charged with the necessaryquantities of refrigerant and oil and then tested at the operatingconditions normally required by the customer. The machine�shydraulic circuit is equipped with drain plugs and open ventvalves; the free---cooling coils are supplied dry to avoid possibleproblemsdue to frost in the storageperiod. Immediately inspectthe machine carefully on delivery to check for damage duringtransportation ormissing components; possible claimsmustbemade immediately to thecarrier and the factoryor its representa-tive.

1.4 --- General descriptionMATRIX R units with air ---cooled condensers have been de-signed and manufactured for producing chilled water.They are also available in versions with a built --- in freecoolingmodule, in versionswith heat recovery for simultaneous heatingof thermal circuit water, with a pump assembly installed on themachine and/or inertial buffer tank inside themachine; the chill-ing units can be equipped with several options indicated in theprice list.The �MATRIX R� product line has been designed utilising thestate---of --- the---art techniques available nowadays in the indus-try, and includes all the components necessary for automaticand efficient operation.The Matrix R units are specifically designed for indoor installa-tion (protected from weather agents), for the connection with

ducts of condensation air in machine intake (if present) andoutlet.Eachunit is completely factory assembled; after evacuation, thenecessary quantity of refrigerant is added to the refrigerant cir-cuit(s) and the unit is tested.All theunitsareequippedwithoneor two independent refrigerat-ing circuits, each one composed of: an air ---cooled condenser,a hermeticScroll compressor andabraze---weldedplateevapo-rator. The components of the liquid line are the charging valves,filters---dryers, solenoidvalve, shut---off valve,moisture indicatorand thermostatic expansion valve.The hydraulic circuit --- with max. working pressure 5 bar --- ismade up on mod. 004---016 of hydraulic lines both in steel andflexibleEPDM rubber, connectedby fittingsand threaded joints,on mod. 017---032 of carbon steel pipes connected withgrooved---end (Victaulic) fittingsand couplingsand includealsoa flow switch (optional) and, in the freecooling versions, chilledwater coils and a three---way valve.Thehermeticscroll compressorsare completewith the followingprotection/safety devices: oil heater (if necessary), electronicprotection monitoring the temperature of the motor windingsand the direction of rotation (the latter may be enclosed in theelectronics of the compressor or external, depending on themodel).Fans are radial type, with aluminum reverse curved blades andstructure, statically and dynamically balanced, directly coupledto amotor with external rotor. It is always available the fan speedcontrolwhichnormally is achieved throughanadjusterwithcon-tinuous speed modulation.By simplymodifying theparameters (of theMicrofacemicropro-cessor control), limiting the fanmax. rotation speed, it ispossibleto change the useful air static pressure (equal to the differenceof the static pressure between the delivery and suction ductsconnected with the unit).The �MATRIX R�water chillers are controlled by the �MICROFA-CE�microprocessor,managingall theunit operatingconditions.The user can change and/or modify the operating parametersthrough the display keyboard installed on the electrical panel.The electrical control board is equipped with all the safety andoperating devices required for reliable operation. The compres-sormotors are equippedwith protectionon all three phasesandare started by three---pole contactors.

2 --- Preliminary Operations2.1 --- Operating limitsThe units can operate within the indicated operating limits (seeTab. 6). These limits apply to new machines, subject to correctinstallation and maintenance.S Ambient air minimum temperature: ---25ûC for Superchiller,---10ûC for Chiller (either Triac or EC fan);

S Maximumoutdoor air temperature is in relation toeachmod-el, as indicated in Tab. 6. In any case outdoor temperaturesaver 45ûC are not admitted; such limits are determined byelectrical and electronic components fitted on units;

S Maximum water flow allowed: depending on the pressuredrop corresponding to the required thermal difference (usu-ally not lower than 3.5ûC --- 4ûC);

S Minimum allowed water flow: compatible with a sufficientevaporation temperature, to avoid the intervention of thesafety devices (to be evaluated for a thermal difference nothigher than 8ûC);

S Temperature range of the water exiting the evaporator: 4ûC--- 15ûC;

S Maximum temperature of the water entering the unit: 20ûC;higher temperatures are allowed only at the system start---up and not during normal operation;

S Maximum glycol concentration: 50% (35%with the optionalpump assembly installed on the machine);

2

S Minimum allowed glycol concentration: depending on theminimum temperature of the ambient air expected at theinstallation site (see Tab. a);

S Maximum difference of air side pressure (between the onein the delivery duct and the one, possibly negative, in thecoil suction) equal to the max. one indicated in Tab. 9 nextto the max. signal = 10 V set on the microprocessor;

S Maximum pressure of the hydraulic circuit: 5 bar;S Voltage range for the electric supply: 400 V +/---10%; max.phase difference: 3%; tolerance on frequency: 1%.

Storage conditions: ---20ûC ÷ 45ûC for all MATRIX R models.

2.2 --- Sound pressure levelsTheTab. 7 shows the noisedata for the units in standard config-uration (without pumps), operating continuously andmeasuredat 1 m from the coil side unit, with ducted air delivery and 50 Paof useful static pressure, in free field conditions.The highest noise levels are detected for higher useful staticpressures of the air.Note:Avoid positioning in areas with possible reverberation of thesound waves; acoustically insulate both the delivery and the in-take ducts (if installed); failure to do this can adversely effect thenoise levels.

2.3 --- TransportS Handle the unit by lifting it with a crane from above;S The lifting holes arepositioned in the frame�sbase (when lift-ing, use spreader bars to protect the sides, see Fig. 3, Fig. 4and Fig. 5).

Note:Place the lifting tubes in the holes in the base indicated by �LIFTHERE�. Lock the ends of the tubes with the locking pins andsplits pins as shown in Fig. 3 and Fig. 5. As an alternative (onmod. 004---016 only), shackles/hooks (optional) fastened at thebase ends can be used as a lifting system: in this case the liftingpointmust be on the vertical line passing through themachine�scentre of gravity (as indicated in Fig. 4) to prevent any load im-balance.The capacity of the lifting gear must be adequate to lift the loadin question. Check theweight of the units, the capacity of the lift-ing gear and ropes and the condition and suitability of theafore-mentioned equipment.

2.4 --- FoundationsS Theunitmust beplacedon a level surfacewhich will supportits weight.

S If necessary, position theunit on suitable anti ---vibration sup-ports that canbesupplied asanoption (in rubber or spring---type). Refer to the manual �Installation of the spring anti ---vibration supports� for their correct positioning.

S When positioned, level the unit.Note:For weight distribution see Fig. 6 and Fig. 7.Note:Theweights and their distribution refer to standard units withoutoptions; if the pump assembly, or other options are installed onthe machine, add the weights of the installed accessories tothose of the standard units (see Tab. 8).

2.5 --- Service areaS In order to allow free air flow or to enable the ducting installa-tion and maintenance of the unit, a minimum area must beleft free of obstructions around the unit (see Fig. 1 andFig. 2).

S Avoid recirculation of hot air between the outlet and the out-door intake of the air conveyed in the ducts, otherwise theunit performance may be impaired or the standard oper-ation can be interrupted.

3 --- Installation3.1 --- Aeraulic connectionsThe Matrix R units are arranged with connection flanges for theair intake and delivery ducts; if the units are ordered with metalfilters to protect the condensing coils, the connection flanges forthe intake side ducting are not supplied, as there is no duct toenable the cleaning of such filter.Connect the ducts fitting flexible joints to prevent transmittingvibrations and to compensate thermal expansion. Check if theholes on the walls --- where the intake and delivery ducts arefitted --- are protected by suitable anti ---rain grilles (equippedwith pre--- filter like the intakeones) toavoidwater or dust toenterin the chiller.All fans are adjusted at the same speed, so that it is not necess-ary to install overpressure dampers next to each fan discharge.The units are supplied with a setting in the microprocessor forthemax. fan speed of 50 Pa useful pressure; set themax. speedaccording to the features required by the installation (seeTab. 9).The units are supplied with the condensation air discharge up-wards; during the installation, it is possible to change the posi-tion of the air discharge opening (with right or left horizontaldirection) by simply inverting the position of the drilled panelwith the closed one of the required side (see size drawings).

3.1.1 -- External air temperature probe installationInstall the external air temperature probe (shipped inside theelectric panel), at the end of the air intake duct.The bulb must be positioned as much outside as possible butmust not be exposed to direct sunlight or weather agents suchas rain or snow. The unit operation could be jeopardized if theseprecautions are not applied.If the intake sideduct is not present, fasten the probe in the roomso that it can correctly detect the external temperature of the coilintakeouterairwithoutbeing influencedbyother external factors(sun rays, rain or snow, other heat or radiation sources, etc.).

3.2 --- Hydraulic connections3.2.1 -- Hydraulic circuit construction (Fig. a)The piping must be connected to the chiller. Construct a chilledwater circuit as described below, see Fig. a:1) Place shut---off valves within the circuit to allow servicing;2) Install a pump system suitable for the flow rate required ata pressure head equal to the sum of all the pressure drops(see project data).Matrix R chillers can be equipped, upon request, withpumps having performance as indicated in Tab. 8;

3) Install manometers at the chiller inlet/outlet;4) Install thermometers at the chiller inlet/outlet;5) Connect the pipes to the chiller by flexible joints to avoidtransmitting vibrations and to balance the thermal expan-sion; proceed in the same way even if the pump set is out-side the chiller;

6) It is useful to include awater pressure switch to give an earlywarning of low water pressure;

7) Place a mesh filter at the inlets of the pump and water chiller(Can be supplied as an optional accessory ---Not fitted);

8) Install, at the highest points in the circuit, apparatus whichallows the bleeding of air and possibly the filling of glycol;

9) Place a drain valve at the lowest point in the circuit and im-mediately at the outlet of the water chiller;

10) Install a water filling set including the following:a) filling water meter;b) manometer;c) non---return valve;d) air separator;e) removable supply tube, which must be disconnectedafter each charge/top---up;

3

11) For maximum protection ensure that all tubing exposed tolow outdoor temperatures is fitted with anti --- freeze heatersand insulated using closed cell synthetic rubber (elasto-mer);

12) The circuit must include an expansion vessel (with safetyvalve) of suitable capacity;

13) Connect the lines avoiding stresses on the machine innerparts.

Note:If the water chiller is complete with an expansion vessel (sup-plied as an option), check if the capacity is enough, and installa second vessel in the circuit, if required (see par. 8.4).Follow the indications in Fig. c for the correct sizing.Note:The whole circuit must contain a water volume suitable for thecapacity of the installed chiller. Check if the inertial capacity giv-en by the sum of the hydraulic volume inside the machine (in-cluding the volume of the optional interna tank, if fitted) and thesystemvolume issufficient,orpossibly install a tank in thecircuit.Follow the indications in Fig. b for the correct sizing.Note:The hydraulic circuit must ensure a constant water supply to theevaporator in every operating condition. Otherwise, the com-pressorsmaybedamagedby repeated returnsof liquid refriger-ant on their suction.Note:The water flow switch is a compulsory safety component thatmust be installed and correctly wired to the Matrix R chillers,otherwise the guarantee will be invalidated.It is installed, as standard, on units with the optional on---boardpump set, and is available as a option for units without pumpson board: in the latter case the flow switch, if not installed on themachine, canbe installedon thehydraulic circuit by the installer,but it is compulsory that it is wired to the electric panel terminalboard, as indicated on the wiring diagram.

3.2.2 -- Addition of water and ethylene glycolVery important:Add water and ethylene glycol to the circuit with a %dependingon the minimum temperature of the outside air expected at theinstallation site. Do not exceed the nominal operating pressureof the circuit�s components.Notes:

S To avoid stratification run the circulation pump for at least 30minutes after adding any glycol.

S After adding water to the hydraulic circuit always discon-nect the water supply coming from the sanitary supply;this avoids the danger of glycol entering the sanitary watersystem.

S After any topping---up of the water check the concentrationand add glycol if necessary.

3.2.3 -- Water--glycol mixtureWater---glycol mixtures are used as the thermal carrier fluid inverycoldclimatesorwith temperaturesbelowzerodegreescen-tigrade. Determine the ethylene glycol % which must be addedto the water, with the assistance of Tab. a.

Tab. a --Ethylene glycol to be added to water (% inweight of total mixture)

Ethylene glycol(% in weight) 0 10 20 30 40 50

Freezing tempera-ture, ûC (*) 0 ---4.4 ---9.9 ---16.6 ---25.2 ---37.2

(*) Values are for Shell antifreeze 402. For different brands, checkmanufacturer�s data.

For the chiller internalwater volume refer toTab. 1. If theoptionalbuffer tank is installed on the machine, add the tank hydraulicvolume.ALWAYS CHARGE THE HYDRAULIC CIRCUIT WITH THE RE-QUIRED GLYCOL % NECESSARY FOR THE MINIMUM AMBI-ENT TEMPERATURE AT THE INSTALLATION SITE. FAILINGTO COMPLY WITH THIS INSTRUCTION SHALL INVALIDATETHE UNIT WARRANTY.

3.3 --- Connection of the safety valve dis-charge

Safety valvesare installedon thehighpressure sideof the refrig-eration circuit(s): the discharge of these valves must be con-veyed outside through a suitable pipe, having a diameter of atleast that of the valve outlet, without burdening the valve body.Convey the discharge to areas where the jet cannot harmpeople and the surrounding environment.

Fig. b -- Inertia tank sizing

The total optimum hydraulic volume of the system where the Matrix R chiller is installed can be calculated by thefollowing formula:

where:--- V=minimum required total water volume expressed in litres--- Rt=refrigeration capacity expressed in kW--- Xd=differential band set on the control and expressed in degrees centigrade

Please note that the sum of the hydraulic volume of the Matrix R chiller (Vm) plus the volume of the hydraulic circuitconnected to it (Vpc) must be greater than, or equal to the minimum required total water volume (V). If this condi-tion is not satisfied, it is necessary to install an inertia tank (Vpt, as indicated in the Fig. a) with a volume at leastequal to the following value: Vpt=V---Vm---Vpc

Note:The power supply should never be disconnected, except whenperforming maintenance.Operate (open) themain switch before carrying out anymainte-nance work on electrical components.Note:It is forbidden to work on the electrical components withoutusing insulating platforms, and in the presence of water or fogor mist.Note:Thesupply to theexternal pumpassemblymustbemadebeforestarting the chiller and must be kept on as long as the chiller isin use. Incorrect operation will cause the unit to lock---out be-cause of the internal protections (flow switch intervention).Note:Thecompressors are equippedwith anelectronicprotectionde-vice blocking their start if the phase sequence is not correct, orstopping their operation if a thermal relay intervenes. Thisdeviceis essential for the integrity of themechanical andelectricalcom-ponents of the compressors. Reset the standard functions byisolating this device and removing the causes of the lock---out.Note:The chillers are equippedwith their ownmicroprocessor controladjustment. The use of the remote ON---OFF input (located inthe electric panel terminal board) as a system temperature con-trol element is forbidden.

4 --- Start---Up and Operation4.1 --- Initial check1) Check all water connections.2) Open the shut---off valve on the liquid line.3) Ensure that the intake pressure is higher than 4.0 bar; if thisis not the case, prolong pre---heating of the compressor (ifpossible) and check that the refrigerant shut---off valve isproperly sealed, seeFig. 12, Fig. 13, Fig. 14, Fig. 15, Fig. 16and Fig. 17.

4) Open all isolating valves and/or water ball valves.5) In case of climateswith temperatures below zero degreesC,make sure the chilled water circuit is filled with the correctconcentration of water/glycol.

6) Bleed all air out of the chilled water circuit.7) Verify the water flow rate and its direction.8) Ensure that the thermal load is sufficient for start ---up.Caution:The ambient air temperature probe must be positioned in theshade and protected against the weather.

4.2 --- First start---up(or after a long stop)

Operate as follows:1) At least 8 hours before the start ---up, power the crank-case heaters (if any, see point 4) by setting the main iso-lator switchON.Make sure the auxiliary circuit has beenpowered and check the operation (a fault due to an in-correct procedure will invalidate the compressor guar-antee).

2) Open the valves of the refrigeration circuit that had beenclosed before the initial check.

3) Check themachinery supplying the thermal load connectedwith the unit and start the system pump(s).

4) MAKESURETHECOMPRESSOROILHASBEENHEATEDFOR AT LEAST 8 HOURS; start the unit only then. In theunits not equippedwith crankcase heaters (Chillers for sum-mer operation only, without modulating fan speed control),the start must be carried out in the warm season only (exter-nal T > 15ûC), and thus oil pre---heating is not necessary.

5) Make sure the fans rotate in the correct direction (anticlock-wise): check the electrical connections, if necessary.

6) Make sure the pumps rotate in the correct direction.

7) During the unit start ---up an inlet water temperaturehigher than 20ûC is allowed. Under standard operatingconditions check that the limits indicated in paragraph2.1 are not exceeded.

8) Check the correct operation of the control and safety de-vices.

9) Check the outlet temperature of the chilled water (check ifthe set---point set on the controller is reached).

10) Check the compressor oil level.11)With the compressor at full load, check there are nobubbles visible in the frefrigerant sight glass. If there are any,charge the unit according to par. 5.

4.3 --- Starting and stoppingALWAYS ENSURE THAT THE COMPRESSOR OIL HAS BEENPREHEATED.FOR BRIEF STOPPAGES MAINTAIN THE SUPPLY TO THECRANKCASE HEATER (IF ANY).S Start the unit setting the Microprocessor switch ON.S Stop the unit setting the Microprocessor switch OFF.S In case of long stops, turn the machine off using the Micro-processor switch OFF.In this case the compressor crankcase heaters (if any) re-main powered.

S For seasonal shutdown of the unit operate the main switchlocatedon themain electrical power supply. This will discon-nect the compressor crankcase heaters.

4.4 --- Chillers serving special plantsThe units are capable of cooling a water---glycolmixture to tem-peratures close to 0ûC without the need for significantmodifica-tions. In the caseof modification, the set values of the safety andcontrol components must also be changed. This can be carriedout in the factory (at the time of testing) or at the time of installa-tion, only by qualified and authorised personnel.

4.5 --- FreecoolingThe �freecooling� is a system of pre---cooling and/or cooling thewater/glycolmixtureusing ambient airwhen the latter isat a tem-perature below the return mixture temperature. If the outsidetemperature is sufficiently low to dissipate the entire heat load,the refrigeration compressors automatically switch off, and themixture�s temperature is controlled by the fan speed adjust-ment.If the mixture temperature is too high for freecooling, the com-pressors will operate as long as necessary to ensure the correctwater/glycol mixture temperature.

4.6 --- Microprocessor controlConsult the �Microface and Hiromatic� Service Manual.

5 --- Refrigerant and Oil ChargeAll work on pipes or components of the refrigerating circuit un-der pressure must be exclusively carried out by qualified staff,competent in such works.

5.1 --- Refrigerant chargeWHILST REPAIRING THE REFRIGERATING CIRCUIT RE-COVERALLTHEREFRIGERANT INACONTAINER:DONOTALLOW IT TO ESCAPE. NEVER USE THE COMPRESSORFOR THE SYSTEM VACUUM (THIS INVALIDATES THEWARRANTY).S The unit is delivered charged according to the Tab. 2.Warning for the refrigerant charge:S Ensure there are no refrigerant leaks.S Check the refrigerant type in the refrigeration circuit: a unitoriginally charged by the manufacturer with R407C cannotbe charged with R22 and vice versa; possibly apply to theTechnical Support Department.

6

S Charge with the compressor in operation, connecting thecylinder with the charge connector after the thermostatic ex-pansion valve.Flush the connection pipe between the cylinder and thecharging point; tighten the seal joint and then start chargingthe unit. It is imperative that the cylinder is weighed both be-fore and after the operation.

S For the units with R407C the refrigerant charge must bemade exclusively with liquid refrigerant.

S Charge the unit until the bubbles in the sight glass have dis-appeared and the working conditions of the entire refrigera-tion circuit have returned to normal (sub---cooling and su-perheating within the limits indicated below).

S Measure the superheating as follows:1) Detect the temperature on the suction line, close to thebulb of the thermostatic expansion valve,using acontactthermometer.

2) Connect a pressure gauge (bymax. a 30---cm pipe) withthe Schraeder connection and read the correspondingsaturated evaporating temperature.

3) The superheating is the difference between the tworeadings.

4) For the units with R407C refer to the pressure gaugescale indicated with the initials D.P. (Dew Point)

S Verify that the superheating is 5ûC --- 8ûC.S Measure the sub---cooling as follows:1) Detect the temperature on the liquid line using a contactthermometer.

2) Connect a pressure gauge (bymax. a 30---cm pipe) withthe Schraeder connection on the liquid line and read thecorresponding saturated condensing temperature.

3) The sub---cooling is thedifferencebetween the tworead-ings.

4) For the units with R407C refer to the pressure gaugescale indicated with the initials B.P. (Bubble Point)

S Verify that at the condenser outlet, sub---cooling is 3ûC ---5ûC.

IT IS IMPORTANT TO CARRY OUT CHARGING CORRECTLY.Anexcess of refrigerant causesan increase in sub---cooling and

consequent operating difficulties in the hot season; a shortageof charge generates an increase in superheating and possiblecompressor stoppages. Whenever work is carried out on theunit, ensure afterwards that the working conditions are correct,checking sub---cooling and superheating.

5.2 --- Oil chargeContact theTechnical SupportDepartment for thespecificationsof the oil to be used for topping up; the oil changes according tothe type of used refrigerant.NEVER MIX DIFFERENT OILS TOGETHER. CLEAN THE PIP-ING COMPLETELY BEFORE CHANGING THE TYPE OF OILUSED.TOP---UPS OF UP TO 20---30% OF THE TOTAL AMOUNT OFOIL CONTAINED IN THE COMPRESSOR CRANKCASE AREPERMITTED; FOR LARGER PERCENTAGES CONTACT THETECHNICAL SUPPORT DEPARTMENT.

5.2.1 -- Procedure for oil topping--upIf there has been any loss of oil then this must be topped up asfollows:1) Take a clean, dry, transparent container (with volume cal-ibrations) and fill it with at least twice the amount of oil re-quired.

2) Isolate the compressor by closing thecock on the liquid line.3) Connect to the fittings on the compressor body (Schraedervalves) and empty it of refrigerant until atmospheric pres-sure (1 bar) is reached.

4) Using apipe, connect theoil container to theoil service fittingon the lower part of the compressor.

5) Open the oil service cock, lifting the container, so that the oilflows by gravity.

6) Charge the required quantity of oil (make sure the tube al-ways remains below the oil level in the container).

7) Stop the oil flow by closing the oil service fitting, open theshut---off cock on the refrigerating circuit and restore thedrained refrigerant charge.

6.1 --- Setting thermostatic expansionvalve

THIS OPERATION MUST BE PERFORMED BY AN EXPERI-ENCED REFRIGERATION TECHNICIAN.Before beginning this adjustment be sure that the refrigerantcharge is correct, checking the the sub---cooling (3ûC --- 5ûC, asspecified in par. 5.1).The valve has already been factory---set and should be resetwhen the superheating is not between 5ûC --- 8ûC, as follows:1) Important:Ensure that the instructions in par. 5.1 havebeen carriedout.

2) Allow the compressor to operate for 15 mins.3) Measure the superheating as follows:a) Connect a manometer to the Schraeder connection lo-cated on the evaporator outlet tube, and read themano-metric temperature on the scale for the refrigerant used(for the units with R407C refer to the pressure gaugescale indicated with the initials D.P. = Dew Point).

b) Using a contact thermometer, measure the temperatureon the tube coming out of the evaporator, next to thesocket used for the manometer.

c) The superheating is the difference between the tworeadings (b ---a).

4) The superheating must be 5ûC --- 8ûC; if not, set the expan-sion valve as follows:a) Remove the protective cover;b) Turn the adjustment screw to return to the optimum val-ues, tightening it in a clockwise direction to increase thesuperheating, or slackening it to reduce the superheat-ing.

c) Wait about 10 minutes;d) Measure the superheating and repeat the operation ifnecessary.

N.B:If the superheating is too low, there is a risk of poor lubricationandconsequentbreakageof the compressor as a result of pres-sure shock.If the superheating is too high the output of the system is limitedand the compressor overheats.

7 --- MaintenanceThe Maintenance Programme below must be carried out by aqualified technician, preferably working under a maintenancecontract.Before any intervention on the unit or accessing the inner com-ponents (removing the outer panels), always ensure the ma-chine is switched off. If the panels are removed (fans compart-ment) wait for the fan(s) to come to a complete stop beforeaccessing the compartment; if the front panels are removed (onmod. 004---016) or the front lower panels (on mod. 017---032),pay special attention whenworking near the compressor upperpart and the discharge line: they are very hot; possibly wait forthem to cool. Be very careful when operating close to the finnedcoils, as the fins are very sharp.Donot remove the fanprotectiongrille before electrically isolating the whole machine. Do not in-sert foreign matter through the fan protection grille. After themaintenance interventions, always close the unit with the suit-able panels, fastened by the tightening system.

7.1 --- Spare partsThe use of original spare parts is recommended.When placing an order refer to the �Component List� enclosedwith the machine and quote the unit model no. and serial no.

7.2 --- Dismantling the unitThemachinehasbeen designedandbuilt to ensurecontinuousoperation.The working life of some of the main components, such as thefans and the compressors, depends on the maintenance thatthey receive.If the unit has to be dismantled, the job must be done by skilledrefrigeration technicians.The refrigerant and the lubricating oil in the circuit must be dis-posed of in conformity with the laws in force in your country.

8 --- Options and Accessories8.1 --- Pump setOnmod. 004---016 the centrifugal pump units are direct driven,withclose---coupledmotorsandasingleshaft; the inductionmo-tor has 2 poles with IP 54 protection and class F insulation.The materials used for the pump main components are:S Pump body in plastic material PA 6.6 (cast iron in all highpressure freecooling versions and on model 016 in theChil-ler high head pressure version and Superchiller standardhead pressure version);

S Impeller in in plastic material PPO (stainless steel in all highpressure freecooling versions and on model 016 in theChil-ler high head pressure version and Superchiller standardhead pressure version);

S Stainless steel shaft;S Graphite impregnated ceramic mechanical seal (EPDM inall high pressure freecooling versions and on model 016 inthe Chiller high head pressure version and Superchillerstandard head pressure version), suitable for the use ofmix-tures containing ethylene glycol.

The pump units have been chosen and sized to operate withinspecific limits, namely:S Water / ethylene glycol mixtures up to 65% / 35% by weight;S Temperatures of the standard pumped fluid not lower than4°C.

Thehydrauliccircuit includes, foreachpump,a suctionshut---offvalve and a delivery check valve if two pumps are installed, orsuction anddelivery shut---off valves if a singlepump is installed.

Onmod. 017---032 the centrifugal pump units are direct driven,withclose---coupledmotorsandasingleshaft; the inductionmo-tor has 2 poles with IP 55 protection and class F insulation.Pumpcasingsand impellersare incast ironEN---GJL 200,shaftsare in stainless steel, the shaft seal is a unbalanced,mechanicalshaft seal with dimensions according toDIN 24 960 and assem-bly length according to EN 12 756, brass neck ring permits idealconditions for the use of watermixtures containing ethylenegly-col. The pump housing, the motor stool and the motor statorhousing are electrocoated.The pump units have been chosen and sized to operate withinspecific limits, namely:S Water / ethylene glycol mixtures up to 65% / 35% by weight;S Temperatures of the standard pumped fluid not lower than4°C.

The motor stool forms connection between the pump housingand the motor, and is equipped with a manual air vent screw forventing of the pump housing and the shaft seal chamber. It isvery important to carry out this operation as the circulationof liq-uid through theduct of theair vent screwensures lubricationandcooling of the shaft seal.Between the outlets of the two chambers and the dischargeflange, twin---head pumps have a non---return flap valve inEPDM rubber. The flap is opened by the flow of the pumped liq-uid and cuts off the port of the idle pump chamber.

In the electrical panel there are, for all the models of pumps, au-tomaticcircuitbreakers foreachpump; themicroprocessorcon-trolmanages theoperating rotationbetween the twopumpsandstart---up of the stand---by pump if the primary pump fails.For the technical features of the pumps and the hydraulic sche-matic see Tab. 8, Fig. 18, Fig. 19, Fig. 20, Fig. 21, Fig. 21 andFig. 22.

8.2 --- Water chiller with partial heatrecovery (20%)

Thisoptionenables the recovery ofup to20%of theheatnormal-ly rejected by the condensers. The system does not require anyadjustment and is made up of plate heat exchangers installedon each circuit before the condenser. The exchangers are pro-

tected by a suitable anti --- frost heater that operateswhen the sy-stem is stopped. It is recommended that a safety valve beinstalled in thehydrauliccircuit toavoidhazardsdue tooverpres-sures, if there is no water flow through the recuperator.The water temperature at the recuperator inlet (in stable operat-ingconditions)mustbe in the rangeof 25ûC --- 45ûC,with anout-let differential of between 3.5ûC --- 8ûC.

8.3 --- Water chiller with total heat recovery(100%)

All heat discharged by the unit to the condenser is recovered.The system includes an additional refrigerating circuit made upof a three---way solenoid valve, supplying --- in case of hot waterdemand --- a plate exchanger, usually by---passed and sized soas to discharge all condensing heat (also installed before thefinned air condenser in series with it); a check valve, a liquid re-ceiver at the exit of the finned air condenser working as storagefor the needed additional refrigerant charge (see refrigeratingscheme). The recuperator is insulated with closed cell polyure-thane and is equippedwith heaters activated when the recuper-ator is deactivated to prevent frost in winter with the systemstopped or not perfectly drained.The operation in total recovery mode is enabled by an externalcontact. The Microface control will simultaneously suit the fanspeedchanging the fan speed setpoint differently from the stan-dard operation without recovery (practically slowing the fansdown till they switch off); anyway, the operation in recoverymode is enabled alsowithout loadat theusers. Indeed, if theus-ers do not demand heat, the water flowing to the condenserreaches a temperature that does not enable the total condensa-tion of the compressed gas, and the remaining portion of thephase change can thus take place in finned coil without inter-rupting the recovery process through the interventionof thema-chine safety devices.If the plate exchanger is supplied with too coldwater, or if the sy-stem is not preset by the installation technician with a three ortwo---way proportional adjustment valve for the exchanger by-pass (indispensable for cold starts, see following �Recom-mended hydraulic circuit� ), the condensing pressure tends todecrease too much; a prolonged condition of low condensingtemperature below the safety threshold leads the Microface mi-croprocessor control to disable the heat recovery, protecting thesystem from any possible malfunctioning.

8.4 --- Hydraulic circuit accessoriesMade up of an expansion vessel (pre---charged at 1.5 bar, max.operating pressure 10 bar) and a safety valve, set at 5 bar. Theirposition in the hydraulic circuit is illustrated in Fig. 18, Fig. 19,Fig. 20, Fig. 21, Fig. 21 and Fig. 22.S Expansion vessel volume:--- 8 litres for all 004---016 units,--- 12 litres for all 017---032 units.

It is recommended that the total required expansion vessel ca-pacity is always checked, depending on the unit�s internal hy-draulic volume (with the volume of the buffer tank, if installed),theuser circuit volume, theglycolpercentage in themixture,andthe expected maximum temperature variation of the mixture.Thewater flow switch is a compulsory deviceprotecting theunit.It is installed, as standard, on units with the optional on---boardpump set, and is available as a option for units without pumps

on board: in the latter case the flow switch, if not installed on themachine,must be installed on thehydraulic circuit by the install-er andwired to theelectric panel terminal board, as indicatedonthe wiring diagram.

8.5 --- Water chiller with inertia tankThemachinecanbesupplied complete with a buffer tank; it per-forms the inertial stabilizer function, for better compressor op-eration, summed up in the following two points:S it reduces the frequency of the compressor peaks, which ishigher the lower the system thermal inertia, improving theirperformance;

S it naturally eliminates the operational problems caused bysudden load variations (shown by variations of the chilledwater temperature).

The buffer tank is supplied insulated, with a drain valve, ventvalve and connection for immersion electric heaters; maximumoperating pressure 6 bar.Built in carbon steel and coatedwith anti ---condensation insula-tion. It can be installed in all MATRIX R 004---016 versions insidethe coil compartment, while on mod. 017---032 it is installed in-side a cabinet which can be supplied either already connectedto the unit (mechanically and hydraulically jointed to it) or loose(completely separate from the unit).
