Step 1 — Prepare for Installation
PREPARE EQUIPMENT ROOM — Locate compres sor or condensing unit in a well-ventilated area. If natural ventilation is inadequate, provide forced ventilation through ductwork. Check applicable code requirements.
Provide freeze-up protection for water-cooled con densers, water lines and accessories if freezing tempera tures can occur during winter shutdown periods.
Provide sufficient clearance for removal of compressor cylinder heads and valve plates. Allow space on the oil
pump end for crankshaft removal as follows: |
|
5F20, 30, 40, and 60 compressors............................... |
20in. |
5H40, 46, 60, and 66 compressors.............................. |
20 in. |
5H80, 86, 120, and 126 compressors.......................... |
30 in. |
Provide space equal to condenser length for tube removal and cleaning.
Step 2 — Receive Machine (Fig. 1 through 8)
BEFORE UNLOADING — Check unit nameplates against model and serial numbers recorded in job speci fications. Check all items against shipping list, and examine items carefully for any shipping damage. If damage is found or any major component has torn loose from its anchorage, have transportation inspectors examine it before unloading. File claim immediately with shipping company for any loss or damage.

5F,H Open-Drive Compressors
RIG UNIT CAREFULLY — Check that rigging equip ment can safely handle the approximate equipment weights for compressors and condensing units.
Rig and move unit earefully to prevent damage to mounting brackets, refrigerant piping or connections.
Step 3 — Install Unit
TO MOUNT MOTOR ON BASE -- The motor fasten ing set supplied with all compressor units (except 5F20,
30, and all OEM models) |
includes motor blocks and |
shims for motor alignment; |
cap screws, plate washers |
and lock washers for fastening motor to base; taper dowel pins for securing motor position after alignment; and beveled washers for fastening the unit base to accessory vibration isolators.
If vibration isolators are used, attach to base (Fig. 9) To avoid damaging the isolators, lift unit from ends when attaching isolators.
With compressor and motor positioned on the base, check the height of the vibration isolators. Shim between isolators and floor as required to level compressor base. When level, secure vibration isolators to floor. Check that beveled washer (Fig. 9) is in place.
Fig. 9 — Typical Vibration Isolator Mounting
TO MOUNT CARRIER COMPRESSOR UNITS AND CONDENSER PACKAGES — Bolt the compressor’s lower support straps loosely to underside of each support stand and place strips of protective material, such as Fabrica, on straps. Position condenser on stands with hot gas inlet at top of condenser and liquid shutoff valve connection facing compressor end of base. Check that condenser overhangs support stands for same distance on each end.
Remove soldered shipping cap from hot gas inlet. To prevent solder from dripping into inlet pipe while un soldering, rotate condenser until pipe is below horizontal position. Return inlet to upright vertical position.
Tighten lower support straps enough to lift condenser off stands. Place upper straps loosely in position with a strip of protective material between condenser and strap (5F20 and 5F30 units use lower strap only).
TO MOUNT COMPRESSOR BASE ON SUPPORT STANDS — Place compressor base on support stands with 2 extra strips of protective material between top of condenser and base. Bolt base into position with cap screws and lock washers provided.
Step 4 — Assemble Refrigerant Piping and Com ponents — Refrigerant connection sizes are given in Table 4.
COMPRESSOR DISCHARGE PIPING — Refer to Condensing Unit Piping Installation Instructions for information.
REFRIGERANT DRIER — A replaceable-core filter drier is recommended for most systems, and is essential on all low-temperature systems. Mount the field-supplied filter drier in the liquid line. Include a shutoff valve to permit isolation of drier for servicing (Fig. 10).
Install a moisture indicator on downstream side of drier to indicate when drier cartridges need replacing.
FELT FILTERS — Install felt filter supplied with com pressor in suction strainer (Fig. 1 through 5). Remove filter after 50 hours of operation. If clean, discard it; if dirty, clean with kerosene or neutral spirits and insert for another 50 hours of operation. Tag unit to show date that filter was cleaned and reinstalled. Figure 10 and Table 1 give information on replacement filter packages.

Step 5 — Install Multiple Compressors
EQUALIZING LINES — Compressors operating in parallel require interconnecting lines for oil and gas pressure equalization. Special handhole cover plates, equipped with tapped holes for equalizing lines, are avail able as options for sizes 5F40 and 5F60, as well as for sizes 5H40, 46, 60, 66, 80, and 86 eompressors (Fig. 11). An oil float system is an acceptable alternative to equalizer lines.
5H120 and 126 Compressors include factory-supplied,
tapped cover plate. On these compressors, use only lower connection for oil equalization (Fig. 11). Connect gas equalizing line to flange connection shown. Mat ing flange for 1-1/8 in. line is Carrier Part No. DK24CA712 (Mueller Part No. A-5151); gasket Part No. is DK29GA005 (Mueller Part No. A-5152).

5F20 and 30 Compressors have no special tapped cover plate. Use opening for oil sight glass to attach the I -1 / 8 in. line for gas and oil equalization (Fig. 12). Accessory Package No. 06DA900072 provides two I/8-in. line adapters to thread into the sight glass opening. If addi tional equalization is desired, run a 3/8-in. line to the oilfilter plug connection (Fig. I and 2).

Step 6 — Make Electrical Connections
GENERAL NOTES
1. Factory wiring complies with National Electrical Code (NEC). Any field modifications or additions must comply with all applicable codes.
2.*For control circuit information, refer to Accessory Control Panel Installation Instructions.
3.If control circuit power is supplied from a separate source, rather than from a transformer, bring 115-v
power through a field-supplied, 15-amp disconnect, in compliance with NEC Section 440-14 (disconnect must be in sight from and readily accessible from unit).
4.Open control-power disconnect only when servicing
unit. Crankcase heaters must remain energized when unit is not operating.
5. *Factory wiring is for single pumpout control. Do not use pumpout control on equipment used with DX coolers. Wiring label shows field connections used with DX cooler.
6.*Contactor C2 is used with 208-v motors, 25 through 60 hp, and 460-v motors, 50 through 150 hp.
7.*When field interlocks are used, remove jumpers
between terminals 3 and 4, and between terminals 7 and 8 on TB2.
♦Refers to compressor units and condensing units only.
ATTACH POWER WIRES TO COMPRESSOR MOTOR — Attach power wires in accordance with motor manufacturer’s instructions and in compliance with NEC and applicable local codes.
CHECK MOTOR ROTATION — Before connecting motor to compressor, check direction of motor rotation.
Rotation must be in same direction as that indicated by arrow on compressor pump cover (or on plate attached near pump-end bearing housing). If direction is not the same, reverse motor rotation by reversing any 2 power leads to motor.
If rotation of oil pump is reversed, reverse direction of pump rotation arrow as well. At that time make the following adjustments:
All 5F Compressors and 5H120and 126 Compressors — Remove 6 cap screws from oil pump cover (Fig. 1-4, 8). Do not damage gasket. Rotate cover 180 degrees and replace. Arrow at top of oil cover will indicate new direc tion of rotation.
5F40, 46, 60. 66. 80 and 86 Compressors — Drain oil below level of pump-end dome cover (Fig. 5-7). Remove pump-end cover to expose oil pump cover in center of main bearing housing. Rotate oil pump cover 180 degrees and replace it. Replace pump-end cover and reverse external arrow to match new direction of rotation. Proper direction can later be checked without removing pumpend cover.

HEATING A COOLING
INSTALL CRANKCASE HEATER — Wire heater to relay or set of normally closed auxiliary contacts on compressor starter to de-energize it when compressor is operating.
Remove rubber plug from crankcase heater casing (Fig. 1-8), and insert heater element entirely into casing. Element should fit snugly, not loosely. Wire to comply with applicable electrical codes.
When crankcase heater is installed, system can be operated on single pumpout cycle, unless used with a DX cooler.
Table 2 lists crankcase heater packages. Table 3 shows corresponding relays. Use of 2 heaters on a 5H80 or 5H120 compressor requires only one relay.
Control circuit voltage determines relay coil voltage. This voltage must be specified when ordering relays.
See Accessory Compressor Crankcase Heater Instal lation Instructions for additional information.
