Remove sheet metal cover panels from return-bend end of
Module 124B or 134B. Place Module 124B or 134B in
position. The exposed return-bend ends of each module are
now opposite each other and facing the service space. The
compressors of each module are on opposite sides of the unit.
IMPORTANT: Modules must be placed 24 in.
(610 mm) apart and square relative to each other.
The modules are now in position for piping installa-
tion and final assembly. See Fig. 8. For mounting units on
vibration isolators, a perimeter support channel is required
between the assembled unit and the support isolators. The
perimeter support channel must be sized to support the fully
assembled unit. Do not support modules on individual iso-
lation supports. Support channel, hardware, and fasteners are
field supplied.
When unit is in proper location, level unit and bolt into
position with field-supplied bolts.
Step 2 — Check Compressor Mounting
UNITS 38AH044-084 — Compressors are mounted on pans
and are held down by 4 bolts during shipment. After unit is
installed, loosen each of these bolts until the snubber washer
can be moved with finger pressure. See Fig. 10.
UNITS 38AH094-134 — Units 38AH094 and 104 compres-
sors are mounted on rails and held down by rail bolts during
shipment. After unit is installed, loosen the rail bolts to al-
low the rails and compressors to float freely on the springs
located under the rails. See Fig. 10.
Units 38AH124 and 134 compressors are mounted on pans
and are held down by 4 bolts during shipment. After unit is
installed, loosen each of these bolts until snubber washer can
be moved with finger pressure. See Fig. 10.
