Removal And Replacement Of Compressor; Figure 8−19 Compressor - Model 06D - Carrier VECTOR 6500 Operation & Service Manual

3. Frontseat the liquid line service valve. Shut down the
unit when the suction pressure drops to 2 psig (0.2
bar).
4. Monitor the gauges. If the receiver pressure drops
rapidly and the suction and discharge pressures rise
rapidly the liquid line service valve requires replace-
ment before the compressor can be further tested.
5. Backseat the liquid line service valve and restart the
unit. Slowly frontseat the suction service valve. Shut
down the unit when the suction pressure drops to 2
psig (0.2 bar).
6. Monitor the gauges. If the suction and discharge
pressures do not equalize rapidly, the compressor is
not at fault.
d. Check condition of and repair cylinder heads and
valve plates. Refer to Section 8.7.3.

8.7.2 Removal and Replacement of Compressor

a. Pumpdown the compressor. (Refer to Section 8.6.2.)
b. Ensure the unit will not start automatically by dis-
abling any two way communication and placing the
Main Power switch in the OFF position. Disconnect
the high voltage source and lockout/tagout the re-
ceptacle.

Do not unscrew service valve mounting
capscrews all the way before breaking seal.
Entrapped pressure could result in injury.
c. Loosen the suction and discharge service valve
mounting bolts. Tap the valve bodies to break the seal
and then remove bolts.
d. Locate the compressor junction box, item 5,
Figure 8−19. Note location if the power wires on the
terminal plate then remove wiring and compressor
junction box. Disconnect all low voltage connectors.
e. Remove compressor mounting bolts.
f. Remove compressor. Refer to Section 2.9 for weight
of compressor.
g. Draw a small sample of compressor oil and test for
acidity If acid is present a system cleanup may be ne-
cessary.
h. Remove all external compressor components such
as: the unloader coils; discharge strainer; switches,
transducers, temperature sensors & fittings.
