1. Disconnect the oil supply line in two places (Fig. 31 or
32). Cap the oil lines and fittings.
NOTE: Compressor oil lines and fittings between the oil filter
and compressor must be kept extremely clean to prevent
obstruction of the compressor inlet bearing oil orifice. Cap all
orifice lines and fittings during disassembly. The compressor
inlet bearing oil orifice is located at the lubrication block on
top of the compressor.
2. Disconnect the motor cooling inlet flange, the motor
cooling drain flange, optional economizer vapor line
flange, and bearing oil drain flange (Fig. 31 and Fig. 32).
Remove the economizer muffler bracket.
3. Brace the end of the discharge pipe assembly closest to the
compressor if it has not already been removed. Place an oil
pan under the compressor flange to collect oil that may
have accumulated in the discharge pipe assembly. Unbolt
the discharge pipe assembly from the compressor. It may
also be necessary to loosen the bolts that attach the dis-
charge pipe assembly to the condenser.
4. If the cooler has been removed (not applicable for P com-
pressor), rig the suction elbow and unbolt the suction el-
bow at the compressor and vaporizer vent line flanges
(see Fig. 17). If the cooler is still in place, it may be nec-
essary to loosen the bolts that secure the suction elbow to
the cooler.
5. Carefully remove the perforated insulation cutouts that
cover the compressor lifting points. See Fig. 31 and 32.
Replace the lifting shackle thread protector after the com-
pressor is re-installed to prevent insulation adhesive from
fouling the threads.
6. Rig the compressor with lifting eyelets installed in the
two M30 threaded holes provided in the top of the com-
pressor housing (Fig. 31 and 32). Use only M30 forged
eye bolts or M30 hoist rings with a sufficient working
load limit to safely lift the compressor. The rubber vibra-
tion isolators may pull out of the compressor mounting
bracket when the compressor is lifted off of the condens-
er. Applying leak detection soap solution to the outside of
the vibration isolators will make it easier to press the iso-
lators back into position.
7. Cover all openings.
NOTE: To reassemble, follow steps in reverse order. Connect
sensors and cables after major components have been secure to
reduce the risk damaging them.
