INSTALLATION

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

5H80, 86, 120, and 126 compressors

Provide space equal to condenser length for tube

removal and cleaning.

HEATING A COOLING

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.

Open-Drive Compressors

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.

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.

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.

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).

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.

#

A CAUTION

If the special gasket between oil pump cover and
oil pump is damaged, replace with correct gasket
only. Check oil pressure immediately after starting

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.
