Your personal safety and the properoperation of this unit require that youfollow them carefully. The TraneCompany assumes no liability forinstallations or servicing performed byunqualified personnel.

WarrantyWarranty is based on the generalterms and conditions by country. Thewarranty is void if the equipment ismodified or repaired without thewritten approval of The TraneCompany, if the operating limits areexceeded or if the control system orthe electrical wiring is modified.

Damage due to inappropriateinstallation, lack of knowledge orfailure to comply with themanufacturer’s instructions, is notcovered by the warranty obligation.If the installation does not conform tothe rules described in InstallationManual, it may entail cancellation ofwarranty and liabilities by The TraneCompany.

ImportantThis document is customer propertyand is to remain with unit. Pleaseplace in service information pack uponcompletion of work.These instructions do not cover allvariations in systems, nor do theyprovide for every possible contingencyto be met in connection withinstallation.Should further information be desiredor should particular problems arisewhich are not covered sufficiently inthis manual, the matter should bereferred to your authorized Tranedealer.

Installation Requirements

Table 2

1. Copper TubingCopper tubing, fittings andinsulation to interconnect thesuction (S) (wide tube) and liquid(L) (narrow tube) refrigerant linesbetween the indoor and outdoorunits can be purchased locally.It is necessary to purchase thefollowing items:

- Purchase equal lengths of bothtubes and insulation required.Cut the appropriate tube lengths,30 to 40 cm (12 to 16 in.) longeron each one to deepen vibrationbetween units. Wall thickness ofcopper tube should be 0.8 mm(0.0314 in.).Both tubes must be wellinsulated with proper insulationmaterials.

- The length of wiring willdetermine the wire size. Seelocal codes, refer to section ofelectrical installation.

2. Additional Materials- Saddles or clamps to hold

refrigerant tubing.- Insulated clamps or staples

for connecting wire.See local codes.

- Refrigeration oil and tape(armored).

- Putty or similar filter.

Location and Preparation of Units

1. Choose a place as cool as possible.The place should be well ventilatedand the inlet air should not hotterthan the outside temperature (max45OC or 113OF).

2. Avoid the vicinity of heat sources,exhaust fan, etc.

3. Avoid direct sunlight, provideawnings if necessary.

4. The unit should be set on a levelreinforced concrete pad to avoidthe effect humidity. The minimumheight of the concrete pad shouldbe 100 mm. (4"). Unit shall be fixedsecurely to the concrete pad withbolts (not supplied) to preventabnormal noise and vibration.

5. The concrete pad must bepositioned a minimum of 200 mm.(8") from any well and surroundingshrubbery.

6. Minimum clearance on the inlet airside of the unit must be 250 mm.(10") : 1200 mm. (48") on thedischarge air side of the unit and250 mm. (10") on the tubing sideof the unit (Figure 1).

7. When the unit is mounted on a roof,be sure the roof will carry the unit’sweight. Vibration isolation isrecommended to preventtransmission to the buildingstructure.

NoteThe Multi-Split System (Outdoor) Unitshould be installed as close to theindoor units as possible.

9.52 (3/8) 350 - 400 (300 - 340)

12.70 (1/2) 500 - 550 (430 - 470)

1. The principal concerns inrefrigeration tubing are:

- Uniform oil return to thecompressor.

- Pressure drops and their effect onsystem capacity.

- Tube routing and isolation to avoidline breakage, vibration and soundtransmission. Regarding this, theinterconnecting refrigerant linesshould be simple and shorter asmuch as possible.

2. Flare ConnectionsThe units reported in this manualemploy the flare method tointerconnect refrigerant tubes betweenindoor and outdoor units (Figure 2).- The tube end of all refrigerant tubes

should be flared, the tube shouldbe cut and deburred. Be sure nocopper scraps fall in to the tube.

- Be sure to fit a cap to the open endof the tube to keep it free of dustand moisture.

- Avoid bending the tube. If it isnecessary, bend it gently, with aradius of more than 3 or 4 cm.(1 1/2 in. or 1 5/8 in.)

- Cut approximately 30 to 50 cm.(12 in. to 20 in.) longer thanestimated tubing length.

- Before flaring remember to fitthe nut.

- Ream with tube end downwardto avoid copper scraps insidethe tube.

- Remove the flare caps on thetube end.

- Connect the tubes by aligningthe centers of both flares and turnthe flare nuts by hand 3 or 4 turns(Figure 3).

3. Insulate both lines, liquid (narrowtube) and suction (wide tube), toprevent heat loss and wet floor due todripping of chilled condensation.Apply proper insulation material,minimum thickness should be 8 mm(1/3 in.) (Figure 4).

NoteDo not try to bend the tube afterinstallation.

4. Finish with armoring tape.Also see section of condensate drainpiping.

NoteApply refrigeration oil on flare andunion surfaces before connectingthem. This will reduce refrigerantleakage.

- Check the tubing connections andrefrigerant lines before applyingspecified torque. Fasten flare nutsas recommended below.

Condensate Drain Piping

Figure 5

Drain

1. The drain hose should comestraight down the wall to a levelwhere runoff will not stain the wall.

2. There should be no traps and avoidputting the end of the hose in water.

3. To avoid damage to the floor orfurniture when the drain hose isplaced in the room, insulate thehose with foamed polyethyleneor equivalent.

4. After completing refrigerant lines,wining and drain connection, bindthe tubing, wining and drain pipe(check if local codes permit it) intoa bundle by using tape at 100 or200 mm (4 in. or 8 in.) intervals.Make sure the drain tube is at thebottom of the bundle (Figure 5).

MS-SVN005-EN 9

System Evacuation and Purping

The outdoor unit is factory charged.Unit nameplate charge is the totalrequired system charge with 7.5meters of interconnecting lines. Sincethe outdoor unit will not have to beevacuated unless charge has beencompletely lost, leave the suction andliquid shut-off valves closed.

1. Upon completion of installation,evacuate the refrigerant lines andindoor coil (Figure 6).

2. Evacuate unit until the gauge reads350 microns or evacuate at leastone hour for one system.

3. Close off valve to vacuum pumpand observe the micron gauge. Ifgauge pressure rised above 500microns in one (1) minute, thenevacuation is incompleted orsystem is leaking.

- Attach appropriate hose frommanifold gauge to suction andliquid line valves service ports.

- Attached center hose of mainfoldgauges to vacuum pump.

NoteUnnecessary switching of hoses andcomplete evacuation of all linesleading to sealed system can beaccomplished by placing a “T” inmanifold center hose and connectingbranch hose to cylinder of R-22.

NoteEvacuate unit 2 and 3 in the samemanner explained above.This completes system evacuationwith a vacuum pump and the airconditioner is ready for actualoperation.

Electrical Installation

Wiring and grounding must complywith national and local codes.

WiringImportant Safeguards:- Check the unit nameplate for

electrical rating. Be sure wiring isaccording to local codes and wiringsystem diagram.

- A power supply disconnect and acircuit breaker for overcurrentprotection should be provided inthe exclusive line.

- Connect all units electrically withground.

- Wiring should not touch refrigeranttubing, compressor or movingparts.

- The manufacturer will have noresponsibility for the problemscaused by unauthorized change inthe internal wiring.

- Connect wiring firmly.- Use recommended wire length

and size.

Note- Each country has their own field

wiring rules and regulations. Besure the installation complies withlocal electrical codes.

- Nameplate ratings on indoor unitsare for “one-to-one” systeminstallations only.

Checking the system before start up

Once the unit is installed, a check ofthe system is recommended beforestarting the units.- Check that field connections are

correctly made.- Check that units are correctly

installed and there is no tool ordebris near or on top of the unit.

- Check the tubing and theconnections for leaks.

- Check that unit has a properground wiring.

- Check for proper voltage and fusesize.

- Check electrical wire size used is asspecified.

- Check all field wiring for tightconnection.

- Make sure that electrical wiresinside the unit do not contact withrefrigerant pipes.

- Start the system and carefullyobserve operation.
