Placing Unit — There must be 4 ft (1220 mm) for service and for unrestricted airflow on all sides of unit, and a minimum of 8 ft (2440 mm) clear air space above unit. For multiple units, allow 8 ft separation between units for airflow and service.
Mounting Unit — When unit is in proper location, use of mounting holes in base rails is recommended for securing unit to supporting structure, or for mounting unit on vibration isolators if required. Fasteners for mounting unit are field supplied. Be sure to mount unit level to ensure proper oil return to compressors.
Compressor Mounting — As shipped, compressor is held down by 4 bolts. After unit is installed loosen each bolt until the snubber washer can be moved with finger pressure. See Fig. 3.
Refrigerant Piping Connections — Line sizes depend on length of piping required between condensing unit and evaporator. See Table 2. It is important to consider liquid lift and compressor oil return. Refer to Part 3 of Carrier System Design Manual for line sizing information, and Fig. 4 for recommended piping details.
Single Pumpout Control — All units are factory wired to operate on single pumpout control. A factory-supplied liquid line solenoid valve must be installed in the liquid line ahead of the indoor coil. See Fig. 5. Wires from solenoid valve must be in conduit, and a ground wire must be provided to comply with codes.
Failure to properly install liquid line solenoid at the indoor unit as described, without Carrier author ization, may VOID warranty.
If unit is used with a chiller, wiring modifications may be required.
Filter Drier And Moisture Indicator — Every unit should have a filter drier and a sight glass (moisture indicator) field installed. Select the filter drier for maximum unit Capacity and minimum pressure drop. Figure 5 shows recommended locations of filter drier(s) and sight glass. Complete the refrigerant piping from the evaporator to the condenser before opening the liquid and suction lines at the condensing unit. One filter drier may be installed at location A in Fig. 5, or 2 filter driers may be installed at locations B.

Filter Drier(s) and Sight Glass Locations
Receiver — No receiver is provided with the unit; it is recommended that one not be used.
Piping Procedure — Do not remove run-around pipe from suction and liquid line stubs until piping connections are ready to be made. Pass nitrogen or other inert gas through piping while brazing, to prevent formation of copper oxide.
Install field-supplied thermostatic expansion valve in liquid line ahead of each evaporator section. For 2-step cooling, the fleld-supplkd solenoid used must be wired to be opened by control from a 2-step thermostat

NOTE: A, B, C dimensions relate to reference diagram
The purpose of these recommendations is to achieve good mixing of the refrigerant leaving the evaporator suction header for proper sensing by the TXV bulb.
1.A minimum of two 90° elbows must be installed upstream of the expansion valve bulb location.
2.The TXV sensing bulb should be located on a vertical riser where possible. If a horizontal location is neces sary, secure the bulb at approximately the 4 o’clock position.
3.Size the suction line from the evaporator through the riser for high velocity. Enter the suction pipe sizing charts in the Carrier System Design Manual at design tons and equivalent length (for 2 degree F loss). If reading falls between 2 sizes on chart, choose the smaller pipe size.
Suction piping for the high velocity section should be selected for about 0.5 degree F friction loss. If a 2 degree F loss is allowed for the entire suction line, 1.5 degree F is left for the balance of the suction line and it should be sized on that basis. Check that the high-velocity sizing is adequate for oil return up the riser.
If an oil return connection at the bottom of this suction header is supplied with an evaporator, this connection must be teed-in ahead of first mixing elbow. When the compressor is below the evaporator, the riser at the evaporator does not have to extend as high as the top level. After a 15-diameter riser has been provided, the suction line may elbow down immediately.
SAFETY RELIEF — A fusible plug is located on unit liquid line before the liquid valve.
Power Supply — Electrical characteristics of available power supply must agree with unit nameplate rating. Supply voltage must be within limits shown in Table 3.
IMPORTANT: Operating unit on improper supply voltage, or with excessive phase imbalance, constitutes abuse and may affect Carrier warranty. See Unbal anced 3-Phase Supply Voltage, page 6.
Power Wiring — All power wiring must comply with applicable local and national codes. Install field-supplied branch circuit fused disconnect(s) per NEC (National Electri cal Code) of a type that can be locked OFF or OPEN. Disconnect(s) must be within sight from and readily acces sible from unit in compliance with NEC Article 440-14.
GENERAL WIRING NOTES
1.A crankcase heater is wired in the control circuit so it is always operable as long as power supply disconnect is on, even if any safety device is open or unit stop-start switch is off. It is protected by a 5-amp circuit breaker in control power.
2.The power circuit field supply disconnect should never be open except when unit is being serviced or is to be down for a
prolonged period When operation is resumed crankcase heater should be energtedfor 24 hours before start-up. If unit is to be shut down for a prolonged period it is recommended that the suction arid discharge valves be closed to prevent an excessive accumulation of refrigerant in the compressor oil
3. Power entry is at one end only.

FLA — Full Load Amps
ICF — Maximum Instantaneous Current Flow during starting (the point in the starting sequence where the sum of the LRAfor the starting compressor, plus the total RLA for all running compressors, plus the total FLA for all running fan motors is maximum).
LRA — Locked Rotor Amps
MCA — Minimum Circuit Amps (complies with National Electrical
Code [NEC], Section 430-24)
MOCP — Maximum Overcurrent Protection
RLA — Rated Load Amps
*Units are suitable for use on electrical systems where voltage supplied to unit terminals is not below or above listed minimum and maximum limits
t All fans are protected by a single circuit breaker.
4.Maximum field wire sizes allowed by lugs on terminal block are:
350 MCM for models 38AK028 (208/230-3-60), 38AK034 (208/230-3-60, 230-3-50), and 38AK044 (208/230-3-60, 230-3-50)
2/0 AWG for all other models.
5.Terminals for field power supply are suitable for copper, copper-clad aluminum or aluminum conduc tors. Insulation must be rated 167 F (75 C) minimum.
CONDENSER FANS — The fans must rotate counter clockwise when viewed from above. If necessary, correct direction of fan rotation by interchanging any 2 power input wires at disconnect switch. Affix crankcase heater decal (located in installer’s packet) to unit disconnect switch.
FIELD CONNECTIONS
1.Main Power — Bring wires from the fused disconnect switch through hole in bottom rail of unit to control
box (Fig. 6, 7, 8) and connect terminals 1111, [12
13 on line side of terminal block TBl (see Fig. 9).
To comply with NEC Article 440-14, the disconnect must be located within sight from and readily acces sible from unit.
■ 2. 24-v Control Power — Units have single point power connections. Control circuit is directly connected inter nally to unit. Maximum 24-v control circuit is 3 amps.
NOTE: For wire runs up to 50 ft. use no. 18 AWG insulated wire (35 C min.). For 50 to 75 ft., use no. 16 AWG insulated wire (35 C min.). For over 75 ft. use 14 AWG insulated wire (35 C min.).
3.Control Circuit Interlock — An airflow switch may be installed in the indoor air handler to prevent unit from running when indoor air is not flowing. This switch (no. HR81JE001) is available from Service Parts Center, or equivalent can be field supplied. This should be electri cally interlocked in the control circuit, between term
inals I 1 I and I 6 I (for flow switch) on TB2. See Fig.
9 for field wiring. This is in the 115-v circuit. Wires must be run in conduit with ground wire.
4.Transformer Connections — See unit wiring label dia gram, notes 1 and 2, located behind compressor com partment end access door.
IMPORTANT: Ensure power to the crankcase heater is always on (except when servicing the unit). If circuit breakers inside unit shut down the com pressor and condenser fans, crankcase heater remains on.
UNBALANCED 3-PHASE SUPPLY VOLTAGE — Never operate a motor where a phase imbalance in supply voltage is greater than 2%. Use the following formula to determine the % voltage imbalance:
% Voltage Imbalance I ^
= 100 X |
max voltage deviation from average voltage |
|
average voltage |
||
|
Example: Supply voltage is 240-3-60.
AB = 243 volts
BC = 236 volts
AC = 238 volts
Average Voltage = 243 + 236 + 238 = 239 volts
Determine maximum deviation from average voltage:
(AB) 243 - 239 = 4 volts (BC) 239 - 236 = 3 volts (AC) 239 - 238 = 1 volt
Maximum deviation is 4 volts. Determine % voltage imbalance:
% Voltage Imbalance = 100 x —^ = 1.7% 239
This amount of phase imbalance is satisfactory as it is below the maximum allowable 2%.
IMPORTANT: Contact your local electric utility company immediately if the supply voltage phase imbalance is more than 2%.
