MECHANICAL SPECIFICATIONS

OverviewYORK Air-Cooled Condensers, Models VDC-113D10 through VDC-266C60, are available in 66 standard model sizes for air conditioning and refrigeration ap-plications, and may be used with any type of compres-sor for halocarbon refrigerants.

YORK Air-Cooled Fluid Coolers, Models VD-CF113B10 through VDCF268B60, are available in 22 standard model sizes for commercial and industrial fluid cooling and may be used with water or glycol. Contact Johnson Controls for special applications, for example, winter-weather chiller economizer duty or cooling industrial fluids.

Air-cooled condensers’ and fluid coolers’ air-sides op-erate dry (requiring a minimum of maintenance) and do not require pump and water piping installation ex-cept for fluid-side fluid cooling. Vertical airflow units are standard design for low silhouette applications.

Legs Made from heavy-gauge galvanized steel with foot pads and mounting holes on the bottom of each leg.

CoilSeamless copper tubes are expanded into full-col-lar aluminum fins. Fins have a corrugated surface to enhance heat transfer. Fin edges are rippled to work harden and stiffen material for resistance to mechani-cal damage. Return bends and headers are brazed with highly ductile silver-bearing copper alloy. Coil cas-ings and tubesheets are manufactured from galvanized steel. The tubesheets include aluminum inserts to pre-vent wear at the juncture of the tubes and tubesheets.

Prior to shipment, coils are strength and leak tested at design pressure, dehydrated, evacuated, pressurized with dry air or nitrogen, and sealed for shipment.

Condenser coils up to four fan lengths use 3/8 in. OD internally enhanced microfin tubes for optimum per-formance. Five- and six-fan length coils use 1/2 in. OD tubes. Fluid coolers use 5/8 in. OD tubes for low pres-sure drop.

For R-22, R-134a, R-407C, R-404A, and R-507A con-densing, the 3/8 in. and 1/2 in. OD tube coils have a 420 psig (29 barg) design pressure at 250°F (121°C)

for up to a 140°F (60°C) condensing temperature. For R-410A, the 3/8 in. OD tube coils have a 650 psig (44.8 barg) design pressure at 250°F (121°C) for up to a 140°F (60°C) condensing temperature.

For fluid coolers the 5/8 in. OD tube coils have a 250 psig (17.25 barg) design pressure for up to 145°F (62.8°C) entering fluid temperature.

HeadersHeavy-wall copper tube headers are designed for low pressure loss and proper refrigerant distribution. Dou-ble-wide units feature completely separate headers for each system circuit so there is no danger of refrigerant leakage between circuits. Inlet and outlet connections are provided. Integral subcooling is available for con-densers.

HousingThe unit structure is comprised of heavy-gauge galva-nized steel panels coated with baked-on champagne-colored powder paint, which, when subjected to ASTM B117 1000 hour salt spray testing, yields a minimum ASTM 1654 rating of "6". These panels are assembled with high-tensile strength fasteners. Fan panels have long, smooth-radius outlet orifices to ensure high en-ergy efficiency and low noise level. Each fan section is fully compartmentalized to prevent fan windmilling.

Fan GuardsHeavy-gauge OSHA-accepted fan guard design uses corrosion resistant, coated-steel wire.

FansHigh-efficiency, high-strength airfoil-profile blade fans are used for low noise and energy-efficient per-formance.

MotorsTotally enclosed air-over (TEAO) motors have built-in thermal overload (ATO) protection and are inverter duty ready. They feature ball bearings that are double-sealed and permanently lubricated. Standard motor is 2.0 hp, 3-phase, 60 Hz, 200, 230, 460, or 575 volts. Optional 1.0 hp, 3-phase, 60 Hz, 200, 230, 460, or 575 volts and 2.0 or 1.0 hp, 3-phase, 50 Hz, 380, 400, or 415 volts are also available.

ACCESSORIES AND OPTIONS

Special CoilsWhile standard aluminum fins are compatible with most environments, when a unit is subjected to an es-pecially corrosive atmosphere, such as coastal air with a high concentration of salt, special fin treatment may be required. The following options are available for these applications.

Holly Gold Coat – This gold-colored, corrosion-re-sistant, polyester-polymer-coated aluminum fin passes 1000 hours of ASTM B117 salt spray testing. Available only with 3/8 in. OD tube coils.

ElectroFin™ Coat – ElectroFin™ Coat is applied to the completed coil, protecting the tubes, fins, headers, and galvanized steel casing with a coating that passes 5000 hours of ASTM B117 salt spray testing. Does not include shipped loose manifold kit.

Copper-Finned Coils – Copper-finned coils are avail-able for applications where the environment may cause galvanic corrosion of aluminum fins. Available only with 3/8 in. OD tube coils.

Sealtite Conduit™All fan motor wiring enclosed in sealed conduit.

Manifold KitTies dual inlet and outlet connections together on dou-ble-wide units for a single field connection (shipped loose for field installation). Typically used on double-wide condensers for use with a single chiller circuits or double-wide fluid coolers. Not available from factory on units with 4 1/8 in. OD connections.

Motor Wiring Options for Fan ControlMotors are wired to contactors located in a UL-listed NEMA 4, weather-resistant enclosure, which includes a non-fused disconnect switch, motor fuses, contac-tors, and an integral 115 volt control transformer. See Table 10 on page 59 and Table 11 on page 59, for fan-cycling control settings or contact Application Engineering for support. Enclosure ships mounted. If there is a concern about noise due to fan cycling, it is recommended that Head Pressure Control (Variable Speed Drive (VSD) Ready) be used.

Double-Wide Unit Fan Cycling Fan Cycling Options for Double-Wide Units are available with fans cycling in pairs or, for temperature-controlled and pressure-controlled fan cycling, with individual fan-bank fan cycling so the VDC can serve individual chiller cir-cuits.

Fan Cycling Options

Head Pressure Control by TemperatureMotors are wired for temperature-controlled fan cy-cling.

A temperature sensor, supplied with a clip for mount-ing in condenser’s air stream or a bulb well for installa-tion in fluid cooler’s leaving fluid piping, must be field installed. Fans next to the header are always running when unit is activated by run signal. Receivers are not required.

For fluid coolers, the lowest allowable leaving fluid temperature is -13°F (-25.0°C) which can be safely done with 50% Ethylene Glycol or 50% Propylene Glycol and a minimum ambient of -20°F (-28.9°C).

When a glycol heat transfer fluid is used in the YORK VDCF fluid cooler ensure that the fluid maintains the correct design glycol concentration. It is imperative to maintain a high enough concentration to prevent the fluid cooler from experiencing a solution freeze that can permanently damage the coil. Johnson Controls recommends that the fluid be checked to verify that the correct concentration is maintained at the beginning of seasonal cold weather or any time the system is opened or a leak is discovered.

It is also important that the unit is rated for the concen-tration of glycol that will be used. Higher concentra-tions than required will reduce the unit's heat transfer capacity and increase fluid pump horsepower.

The concentration required for the given application will depend on the particular glycol-based heat transfer fluid used and the lowest expected temperature. Differ-ent fluids have different specific gravity, specific heat, viscosity and thermal conductivity at different percent-ages and temperatures. Typically the system should be protected to 15 degrees below the lowest anticipated temperature. The fluid manufacturer's recommenda-

tions should be closely followed for your particular ap-plication.

The A350 controller and stage module are supplied with this option to control the fans.

Head Pressure Control by PressureRequired when selecting a VDC for use as a remote condenser for a YCRL chiller. Motors are wired for pressure-controlled fan cycling. Included pressure transducer(s) must be field installed. Fans next to the header are always running when unit is activated by run signal. Receivers are not required.

The P470 controller and stage module are supplied with this option to control the fans.

Head Pressure Control (VSD Ready)Motors are wired for variable speed fan control. VSD bypass control circuit is included, but inverter drive (VSD) is not included. Temperature or pressure sensor(s) for control must be field provided and in-stalled, if desired.

Field-installed inverter drives (VSDs) shall be mounted on or in close proximity to the VDC unit. The inverter drive shall be equipped with load reactors for installa-tions that require more than 25 feet of wire between the inverter and the VDC unit or whenever distortion is a concern to prevent voltage spikes that can damage the fan motors and void the VDC motor warranty. Motor damage caused by an improperly installed VSD is not warranted.

The VSD’s switching frequency shall not exceed 4 KHz.

When this option is selected, the option Sealtite™ Conduit on page 11 shall also be selected to ensure that the motor wire is shielded from voltage spikes. Grounding of conduit and all wiring is of extreme im-portance. See Figure 18 on page 56 and VSD Invert-er Wiring on page 64.

SECTION 3 - HANDLING AND STORAGE

PREFACEYour Johnson Controls Air-Cooled Condenser or Fluid Cooler incorporates the finest in engineering design, materials, and corrosion protection to provide a rugged long lasting unit. Proper installation, care and mainte-nance of your unit are essential to good performance and long life. Before rigging or beginning work on the unit, Johnson Controls recommends that experienced refrigeration contractors, operators, and maintenance technicians are formally trained on the Johnson Con-trols Air-Cooled Condenser features.

Reading this manual is a minimum re-quirement.

Before installing your unit, we suggest that you read the following instructions carefully and keep them handy for ready reference.

After installation, the unit must be properly connected to appropriately designed and installed refrigeration systems. The engineering plans, piping layouts, etc., for the Johnson Controls Air-Cooled Condenser or Fluid Cooler and associated system components must be detailed in accordance with local/governing codes and the best industry standards and practices such as those outlined in current industry literature. Reference the DX Piping Guide, Form 50.40-ES2 and the 2010 ASHRAE Refrigeration Handbook, Chapter 1, espe-cially noting the Safety Requirements section for high pressure refrigerants on page 1.35.

SHIPPING INSPECTIONCarefully examine the unit and notify the transporta-tion agent of any missing parts or damage. It is advis-able to inspect the unit as soon as received and to make a record of the serial number, and motor data.

The unit shipment should be checked on arrival to ensure that all major pieces, boxes and crates are re-ceived. The unit should be checked on the trailer or rail car before unloading, for any visible signs of dam-age. Any damage or signs of possible damage should be reported to the transportation company immediately for their inspection. Contact the Johnson Controls Re-gional or District office in order for a Johnson Controls Representative to assist in filing damage claims.

Johnson Controls will not be responsible for any damage in shipment or at job site, or loss of parts, if these shipping inspection instructions are not followed. (Refer to BOS Document Submitting and Processing Claims for materials lost or damaged in transit. 13-91.202-BEHQ)

Once received at the job site, all containers should be opened and contents checked against the packing list. Any material shortage should be reported to Johnson Controls immediately. (Refer to Shipping Damage Claims, Form 50.15-NM.)

COIL INSPECTIONThe refrigerant coil has a low pressure charge from the factory. Check the coil to see that the holding charge is intact. To do this, remove the 1/4 inch cap and briefly depress the Schrader valve located on the liquid or suc-tion header of each circuit to verify pressure. The charge must be maintained until refrigerant or fluid piping is connected to the unit. A coil that does not have a charge may have been damaged during transit. If the charge is not present when the unit is received, the coil must be pressure tested to 100 psig with dry nitrogen gas to confirm that it is leak free. Contact Johnson Con-trols before installing any air-cooled condenser or fluid cooler unit that has lost the factory charge. When com-municating with the factory, refer to the model and se-rial numbers which are located on the unit nameplate.

SAFETY REQUIREMENTSOnly experienced, qualified personnel should install, operate and maintain re-frigeration equipment.

Perform frequent visual inspections and continuously monitor a condenser to prevent the escape of refrig-erant. Use electronic refrigerant detectors in the unit proximity for continuous monitoring and detection of the presence of refrigerant in the atmosphere.

SECTION 4 - INSTALLATION

MOUNTINGOnce the unit is placed in the desired location, secure legs to floor or steel work with 3/4" diameter bolts to prevent movement. The top should be level and the unit should be supported along its entire length (i.e., every leg should be secured). Use of vibration pads or isola-tors is recommended. The supporting structure must be strong enough to support the weight of the unit.

CRANE RIGGING INSTRUCTIONSAll units are designed for removal from the truck by crane only. Use lifting brackets shown on Figure 2 on page 15. Be careful to lift units evenly and balanced to avoid undue stress on the equipment.

Refer to customer submittal drawings for dimensional data and weight before installing units.

LOCATIONJohnson Controls remote Air-Cooled Condensers and Fluid Coolers are designed to meet practically any requirement for mounting either indoors or outdoors. Care should be taken not to mount the unit where it is continually exposed to loose dirt or foreign matter which might clog the coil surface. The unit must be mounted in a level position, both front-to-back and side-to-side.

An important consideration when locating the con-denser is providing for adequate airflow to and from the unit. A minimum distance of four feet is recom-mended on all sides of the unit, with eight feet mini-mum recommended between adjacent air-cooled con-densers. The capability and performance of the unit is dependent upon the unimpeded flow of ambient air over the extended surface for removal of heat from the refrigerant discharge gas within the coil.

Solar effect has negligible bearing on the performance of the air-cooled condenser.

Indoor ApplicationsWhen the condenser or fluid cooler is mounted indoors, the air leaving the unit must be discharged to the out-doors to prevent recirculation of heated air through the unit. Provision must also be made for sufficient fresh air intake into the area where the unit is located.

When a discharge duct is used with a propeller fan, the duct's added static pressure leaves the unit subject to diminished heat transfer capacity because of a reduc-tion in airflow. The unit's rated capacity can be pre-served by designing the duct for negligible pressure loss, by the addition of an external fan to overcome the duct's static pressure, or by a combination of the two.All fan guards should be removed and access provid-ed in the duct to allow for servicing the fan and drive assemblies. A flexible duct connection will minimize noise transmission.

If louvers are to be installed on the duct outlet, the free open area should equal the duct cross sectional area.

For ducts of greater or lesser cross sectional area, spe-cial fans and motors can be furnished by Johnson Con-trols. Consult the factory for specific recommendations and pricing.

If inlet ducts are not provided, unrestricted flow of fresh air to the unit must be ensured. Care must be tak-en to ensure that the fresh air supplied is at the ambient air temperature. If air is taken from an area where the heat exceeds the ambient air temperature, the unit’s ca-pacity will be reduced. The arrangement must ensure that heated condenser discharge air is not re-circulated to the air intake of the unit.

Outdoor ApplicationsYour Johnson Controls Air-Cooled Condenser or Fluid Cooler has the fan motor(s) located inside the casing and requires no special provisions for weather protec-tion.

Multiple units should be installed so that the discharge of one unit is not directed into the intake of another unit.

A vertical airflow unit may be located without regard to prevailing wind. These units minimize fan noise and allow greater flexibility of location in relation to sur-rounding structures.

When installing condensers and fluid coolers, a loca-tion should be chosen so that at least three sides of the unit have unrestricted airflow. The fan should have free flow unrestricted by any overhanging structures.

The unit may be placed close to a building on one side with a minimum clearance of eight feet. In the case of multiple unit installations, units may be placed end-to-end without penalty and side-by-side with a minimum of four feet apart for single-wide and eight feet apart for double-wide units. Where located on a roof, it is best to mount the unit with the longer side parallel to the roof edge to minimize the potential for drawing heated air from the roof surfaces.

The rugged mounting legs of the Johnson Controls Air-Cooled Condensers and Fluid Coolers are designed to provide sufficient height for any operating condition. Mounting pads should be located for ground level in-stallation. When the unit will be located where an ex-cessive buildup of superheated air is expected, the unit should be mounted in a structural open frame.

FORM 195.29-NM1 ISSUE DATE: 10/12/2020SECTION 4 - INSTALLATION

WIRINGA disconnect, as required by local codes, should be provided for each motor circuit. The motors have in-ternal thermal overload protection; therefore, multiple motors may be started from each circuit. See SECTION 5 - TECHNICAL DATA for wiring diagrams.

With factory wired motors, verify that the supply volt-age is the same as the motor nameplate voltage.

For field wiring, check the wiring terminals inside the motor to ensure that they are wired for proper power supply voltage. The wiring diagram is attached to the motor housing. Also, confirm fan rotation direction as indicated by the fan blades.

CORROSIVE ENVIRONMENTThese units must not be installed in environments that may be corrosive to the materials of construction. This could result in reduced performance, condenser fin de-terioration and coil leaks not covered by warranty.

ELECTRIC POWER SUPPLYCheck the electrical characteristics on the unit name-plate to make sure the power supply is the same. Only qualified electricians should install the power supply. All work should be done in conformance with prevail-ing codes and regulations.

Do not remove safety equipment or warn-ing labels from equipment. Removal could result in serious injury or death.

Disconnect the power supply to the unit before performing any service or mainte-nance. The disconnect should be locked in the “OFF” position following proper lockout tagging procedures.

REFRIGERANT PIPING - CONDENSERSpecial care must be taken to ensure adequate sizing of refrigerant piping for Johnson Controls Air-Cooled Condensers. Applicable standards should be consulted in this regard. The copper tubing should be de-oxi-dized and dehydrated Type L refrigeration tubing with wrought copper fittings employed. Keep all piping clean, and clean all pipe connections with a wire brush or the equivalent. Braze with 5% silver braze material with the recommended flux. Use a wet rag around the next solder joint when brazing.

Piping systems with halocarbon refrigerants must be properly evacuated to remove noncondensables and moisture prior to the introduction of refrigerant. A vac-uum of 750 microns is the minimum requirement to remove moisture.

The liquid drain line should not be exposed to high temperatures, and therefore should be insulated if it passes through an environment where temperatures exceed 120˚F. All refrigerant piping must be well sup-ported and protected from vibration. The condenser piping connections should not be left open to the atmo-sphere for any longer than required for solder connec-tions to be made.

Install a shut-off valve at the receiver inlet (if used). Install a purge valve or fitting at the highest point in the discharge gas piping.

In order to prevent condensed liquid refrigerant from causing damage to the compressor(s), install a trap in the vertical discharge piping at the compressor(s). The height of the trap should be 6 inches for every 10 feet of vertical discharge piping. If the height of the vertical piping makes this impractical, the trap may be replaced by a check valve.

When installing refrigeration piping, make certain that it is well supported. Make sure the vibrations from the compressor, condenser and piping are not transmitted to the building. The use of a discharge muffler may be necessary to prevent noises due to refrigerant pulsa-tions; particularly with high speed compressors.

REFRIGERANT LINE SIZINGRefrigerant piping systems must be designed to pro-vide practical line sizes without excessive pressure drops to prevent compressor oil from being "trapped" in the refrigerant piping, and to ensure proper flow of liquid refrigerant to the thermal expansion valve. Be sure to review DX Piping Guide, Form 50.40-ES2. Considerations should be given to:

1. Discharge line pressure drop due to refrigerant flow.

2. Discharge line refrigerant velocity for oil return.

3. Liquid line pressure drop due to refrigerant flow.

4. Liquid line pressure drop (or gain) due to vertical rise of the liquid line.

5. Pressure rating of brazed Type L Copper tubing with high pressure refrigerants.

JOHNSON CONTROLS 17

SECTION 4 - INSTALLATIONFORM 195.29-NM1 ISSUE DATE: 10/12/2020

To ensure a solid column of liquid refrigerant to the ex-pansion valve, the total liquid line pressure drop should never exceed 40 PSI (276 kPa). Refrigerant vapor in the liquid line will measurably reduce valve capacity and poor system performance can be expected.

To allow adequate oil return to the compressor, dis-charge risers should be sized for a minimum of 1000 FPM (5.08 m/s) while the system is operating at mini-mum capacity to ensure oil return up the suction riser.

Chiller Below CondenserOn a system where the chiller is located below the condenser, the discharge line must be sized for both pressure drop and oil return. In some cases a double discharge riser must be installed to ensure reliable oil return at reduced loads.

Condenser Below ChillerWhen the condenser is located below the chiller, the liquid line must be designed for both friction loss and static head loss due to the vertical rise. The value of static head loss of 5 PSI/ft. (3.4 kPa/30 cm) must be added to the friction loss pressure drop in addition to all pressure drops due to driers, valves, etc.

OIL TRAPSAll horizontal discharge lines should be pitched at least 1/4" per foot (2 cm/m) in the direction of the refriger-ant flow to aid in the return of oil to the chiller. All discharge lines with a vertical rise exceeding 3 feet (.91 meters) should have a "P" trap at the bottom and top of the riser. Discharge lines with a vertical rise exceeding 25 feet (7.6 meters) should be trapped every 15 feet (4.6 meters).

REFRIGERANT PIPING REFERENCE

R-410A Copper Line SizingWhen selecting pipe diameter and material for remote condenser piping R-410A systems, it is recommended that ASTM B280 material is used.

YCRL Line Sizing NotesIf the VDC is used in conjunction with a YCRL chiller with a design pressure of 650 psig, a mechanical high pressure cutout to shut the unit off at 585 psig, and (the unit) is rated at 650 psig, the maximum discharge pipe diameter that can be used is 1-5/8".

For more details, refer to the 2014 ASHRAE Refrigera-tion Handbook, Chapter 1, and note that brazing re-duces the strength of the heated pipe material to that of annealed material.

Suggested Field Piping ArrangementsThis section shows four field piping arrangements for remote air-cooled condensers in field erected systems using receivers.

Receivers are shown in Figures 3 through 6 for convenience. Many applications do not require receivers when the volume of the refrigerant charge does not ex-ceed 80% of the condenser coil internal volume and can be stored entirely in the condenser coil.

FIGURE 3 - CONDENSER, COMPRESSOR AND RECEIVER ON SAME LEVEL

LD16218

Figure 3 on page 18 covers a common application where the air- cooled condenser is located on the same elevation as the compressor and receiver. The discharge line in this case is not too critical. The main problem usually associated with this arrangement is insufficient vertical height to allow free draining of the liquid re-frigerant from the condenser coil to the receiver.

To prevent gas binding in the receiver and liquid build-up in the condenser coil, locate the receiver as far be-low the condenser outlet as possible. Liquid lines must be free of any loops or traps and horizontal runs must be pitched toward the receiver.

Figure 5 on page 19 illustrates a typical piping arrange-ment where the remote air-cooled condenser is located on a higher elevation than the compressor or receiver. In this arrangement, the design of the discharge line is very criti-cal and should be modified to the arrangement in diagram Figure 4, unless a very constant and steady load is main-tained.

FIGURE 6 - TWO OR MORE CONDENSERS CON-NECTED TO ONE COMPRESSOR

Figure 6 on page 19 illustrates another common ap-plication where two or more separate air-cooled con-densers are interconnected to a single compressor. In this case, each condenser must have both equal ca-pacity and equal pressure drop. The piping must also be arranged to ensure equal lengths to and from each condenser. If unlike piping and/or unequal condensers are used, the unequal pressure drop will cause liquid to build up in one of the condensers, reducing its effective capacity.

RECOMMENDED REFRIGERATION LINE SIZESThe recommended refrigerant line sizes (discharge line-compressor to condenser and liquid line-condens-er to receiver) can be determined from the DX Piping Guide, Form 50.40-ES2, while exercising care with regards to internal working pressure of copper piping with brazed joints for use with high-pressure refriger-ants.

RECEIVER LOCATION (IF REQUIRED FOR REFRIGERANT STORAGE)It is preferable that the receiver be located in an ambient temperature above 65°F. When located in a lower ambi-ent temperature, provision should be made to heat and insulate the receiver, especially if long off-cycles are en-countered. Table 1 on page 21 shows suggested receiv-er and heater sizes. The receiver should be insulated with 1-inch thick Armaflex insulation or equivalent. Before applying the receiver insulation, the heater cable should be wrapped around the receiver throughout the length for even heat distribution. The heater must be field connected to the proper voltage and controlled so that it is energized on system shutdown.

REFRIGERANT CHARGEThe chiller is charged and shipped with a dry nitro-gen holding charge. The chiller and the remote piping condenser must be evacuated and the operating charge for the chiller, remote condenser and refrigerant pip-ing must be weighed in after all refrigerant piping is installed, leak checked, and evacuated. A minimum of 70% of the calculated complete system charge must be installed before attempting to operate a system. Final adjustment of refrigerant charge should be verified by subcooling values.

Use of refrigerant other than that stamped on the nameplates may cause damage to the refrigeration coils. Coil must not be subject to higher pressure than design pressure stamped on the nameplate.

The total system refrigerant charge is the sum of the operating charges of the evaporator, condenser and re-frigerant piping. The Refrigerant charge for discharge lines and liquid lines may be found in Tables 15 and 16 respectively on pages 28 and 29 of the DX Piping Guide, Form 50.40-ES2. The pump down capacity of the condenser should be equal to or greater than the total refrigerant charge required. Pumpdown capacity is normally the sum of the evaporator, condenser and refrigerant piping charges multiplied by 1.25.

SECTION 7 - UNIT OPERATION

STANDARD FAN CYCLINGAir-cooled condensers must operate at lower than de-sign ambient dry bulb temperature. A minimum oper-ating pressure must be maintained under all ambient operating conditions to ensure sufficient pressure and satisfactory system operation. Therefore, if air-cooled condenser operation below 40°F ambient temperature is required, refer to Fan Cycling Options on page 11 and Low Ambient Control Options on page 60.

The capacity of an air-cooled condenser is directly pro-portional to the TD, which is the temperature difference between the condensing temperature and the air dry bulb entering the condenser. A condenser is normally selected to operate on a “TD” suitable for summer am-bient temperature conditions. The capacity of this con-denser, however, is substantially increased when oper-ated with low ambient temperatures. The result of the increase in condenser capacity is to reduce the system head pressure. When the ambient temperature drops below a certain value, the head pressure falls below the point where the expansion valve cannot properly feed the evaporator and very poor or unsatisfactory system operation results.

On multiple fan units, individual fan sections can be cycled to not exceed nominal condenser capacity at low ambient conditions. Table 10 on page 59 provides minimum ambient temperatures for this method of con-trol. Table 11 on page 59 gives individual thermostat settings for all units referenced to various design tem-perature differences. In lieu of thermostats, fan cycling can be controlled by pressure switches connected to condenser inlet (hot gas) headers. This is recommend-ed for process applications. Contact Johnson Controls for special pricing.

VDC PRESSURE SETTING GUIDELINESWhen a YORK VDC is used as a remote condenser with a YCRL chiller, the VDC must be ordered and installed with the “Head Pressure Control by Pressure” option, which provides Johnson Controls model P470 pressure controllers factory mounted in the VDC con-trol panel. P470 controller operating manuals, included in the VDC control panel, provide guidance for field fan-staging setup.

Johnson Controls recommends the following pressure set points for general use; if excessive fan cycling is noted the final stage of cycling should be adjusted (deadband increased). The deadband proposed in these guidelines is set to 125 psi, which is the standard set-ting for Johnson Controls air-cooled R-410A units (YLAA, YCAL and YCRL).

Two-stage units (2-fan single-wide, 4-fan double-wide VDC)

• Stage 1, ON when any compressor is ON.

• Stage 2, ON at 380 psig, OFF at 255 psig.

Three-stage units (3-fan single-wide, 6-fan double-wide VDC)




Four-stage units (4-fan single-wide, 8-fan double-wide VDC)





Compressor will unload when the discharge pressure reaches 565 psig.

LOW AMBIENT OPERATIONSince air-cooled condensers are often required to oper-ate over a wide range of ambient air temperatures and variable loading conditions, provision must be made to maintain the overall system balance. Any air-cooled condenser tends to run at a low head pressure when operating in a low ambient air temperature. Low head pressures can result in poor expansion valve operation, which will in turn cause poor system operation.

Within limits, air conditioning applications allow the operating head pressure to vary with the ambient air temperature without adversely affecting the system op-eration. The head pressure lower limit depends upon the required pressure drop across the thermostatic expan-sion valve. For normal air conditioning applications, the low pressure limit should correspond to a condens-ing temperature of 65° to 70°F. This corresponds to an ambient air temperature lower limit of approximately 55° to 60°F. Air conditioning may not be required at or below these ambient temperatures. However, to ensure sufficient receiver pressure during compressor start-up, it is recommended that a high-pressure cut-in switch be used to allow the head pressure to rise before the condenser fan starts.

Many applications, such as commercial refrigera-tion, require operation below the above ranges (55° to 60°F). Johnson Controls offers fan cycling to maintain a desired condensing pressure.

LOW AMBIENT CONTROL OPTIONS

Fan Cycling ControlOn multiple fan units, individual fan sections can be controlled to prevent exceeding nominal condenser capacity at low ambient conditions. Table 10 on page 59 provides minimum ambient temperatures for ef-fective fan cycle control. Lower ambient temperatures than listed are not recommended for this method of control. Table 11 on page 59 gives temperature set-tings for all units referenced to various design tempera-ture differences.

Head Pressure Control by Temperature on page 11 for VDCs and VDCFs and Head Pressure Control by Pressure on page 12 for VDCs can be used to con-trol individual fans in single-wide models and individ-ual fans or pairs of fans in double-wide models.

Head Pressure Control (VSD Ready) on page 12 for VDCs and VDCFs can be used to vary speeds of all fans in unison.

SECTION 8 - MAINTENANCE

GENERALWhen our Johnson Controls remote Air-Cooled Con-denser or Fluid Cooler has been properly installed, it will require little in the way of regular service or main-tenance. A regular schedule of periodic maintenance should be established, which includes a complete an-nual checkup.

Motors are equipped with sealed bearings; no motor grease is required.

CLEANINGWhen visual inspection so indicates, the condenser coil should be cleaned with a vacuum cleaner, compressed air or brush to clear dust and debris which will impede

performance. A clean coil saves energy. Consult the material Safety Data Sheet to determine a cleaning so-lution that is compatible with all parts of the unit. If the unit's casing shows signs of rust, the rust spots should be cleaned and sprayed with a rust preventative.

RECOMMENDED SPARE PARTSSee Renewal Parts Guide, Form 195.29-RP1 for re-placement and recommended spare parts for earlier as well as current models.
