Ⅲ REMOVING THE COMPRESSOR — Follow the steps
below to remove the compressor:
1. Disconnect all power to unit.
2. Remove unit from wall sleeve as detailed in the
GENERAL DISASSEMBLY section. The unit
weighs up to 150 pounds. Seek assistance or use a
lifting device when removing unit from wall sleeve.
3. If the unit is a heat pump: Disconnect the wire
plug on the reversing valve solenoid and carefully
remove the outdoor thermostat capillary from the
outdoor coil.
4. Attach the piercing valve to the suction side pro-
cess tube below the crimps. Attach Carrier
TOTALTEST kit (Part No. TT1-001), to the pierc-
ing valve to verify acidity of the system. After
verifying the system acidity, attach the Totalclaim
System to the access port to remove and clean the
refrigerant.
5. When all the refrigerant has been recovered, re-
move the terminal cover from the compressor with
a nut driver. Disconnect the 3 wires from the
compressor and label the location of each. Once the
wires are labeled, replace the terminal cover to
protect the compressor terminals.
6. Remove the air system assembly by following the
procedure detailed in the SEASONAL CLEANING
section under Accessing the Indoor and Out-
door Coils.
7. Remove the piercing valve and cut the crimped por-
tion of both process tubes off with a small tubing
cutter. Braze a Parker access valve on each process
tube. Using a torch, disconnect the suction and
discharge tubes from the compressor connections.
8. Remove the compressor mounting bolts, and remove
the compressor.
The compressor may still be hot from the brazing
process.
9. For Cooling Only units and Heat/Cool Units:
Remove the strainer and capillary tubes from the
system. A Cooling Only or Heat/Cool unit will have
one strainer located in the liquid line between the
outdoor coil and the capillary tube. The strainer may
be an external bulb type or a tube inserted type.
The tube inserted type must be cut out with a tub-
ing cutter. Remove and save the section of liquid
line tube that was connected to the capillary tube.
Remove and discard the strainer. See Figures 37
and 38.
