HEATING A COOLING
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.
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.

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.
