certified lifting plates to allow safe compressor/
motor assembly removal. Before removing the
compressor/motor assembly, consult with a rigging
specialist. Employ rigging specialist procedures
when removing the compressor motor/assembly.

6. Remove the suction elbow.
There are two styles of suction elbows, a 90° elbow
and a three-piece elbow, that can be found in the
disassembly process.
N N o o t t e e : : Apply oil on steel compressor internal parts
for rust prevention. Only a thin layer of oil is
necessary. Avoid over applying. Use POE
break-in oil.
a. Use a sling to support the 90° elbow style
suction elbow. Apply slight lifting pressure.
b. Three-piece suction elbows have a lifting tab.
You will need a lifting clevis to remove the
elbow. A Crosby screw pin shackle, model S-
209, stock number 1018482 with a 5/8-in. pin is
acceptable as shown in
24
"Economizer
Figure 15, p. 24.
Figure 15. Lifting clevis on the suction elbow
lifting tab (three-piece elbow style)
c. Remove the bolts from the control mounting
bracket on the back of the control panel.
d. Remove the suction elbow bolts at the
compressor and evaporator connections..
e. Lift the suction elbow from the chiller being
careful to avoid damage to flange surfaces.
f. Install protective covers on the evaporator and
compressor connections. Plastic secured with
duct tape makes an adequate cover if no heavy
objects are set on the openings.
7. Support the compressor/motor assembly as
indicated by the rigging specialist (see
not lift the assembly; instead support the assembly
to prevent it from slipping as the compressor foot
and discharge connection flange bolts are removed.
