a. cooler liquid feed.
b. motor cooling supply from condenser.
c. liquid injection to compressor.
d. bubble line to float chamber (not shown).
e. optional hot gas bypass and associated solenoid valve
wiring (not shown).
f. motor power cables from optional unit mounted starter
lugs (not shown).
3. Separate compressor by disconnecting the following:
a. discharge flange from compressor (remove the check
valve).
b. oil supply line to compressor and associated solenoid
valve wiring.
4. Cover all openings.

necting the following:
a. discharge flange from compressor and remove check
valve (Fig. 10).
b. oil supply line to compressor and associated solenoid
valve wiring (Fig. 10).
4. Cover all openings.
5. Be sure the following electrical connections are
disconnected:
a. motor power cables from optional unit-mounted starter
lugs (not shown).
b. motor winding temperature sensor (Fig. 10).
