Installation:
Install the four rubber grommets in the bottom of the new compressor and install the two sleeves where the carriage bolts 1.
will be located. Mount the new compressor and install the three washers and lock nuts and tighten to 45 in-lbs. DO NOT
REMOVE THE RUBBER PLUGS AT THE TUBE STUBS ON THE COMPRESSOR AT THIS TIME.
Install and braze new drier assembly to condenser. Then install and braze the capillary tube and the hot gas valve tube.2.
Remove the plug for the hot gas line at the compressor. Install and braze the hot gas line to the compressor.3.
Remove the plug for the process tube on the compressor. Install and braze in the process tube. Be sure to cap o the end to 4.
prevent any contamination.
Remove the plug for the suction line on the compressor. Install and braze in the suction line from the evaporator. BE SURE TO 5.
REINSTALL THE SUCTION LINE AND TUBING HARNESS INSULATION TUBES.
Reinstall compressor overload and then the starter.6.
Reinstall compressor cap.7.
Reverse steps 1 through 7 of removal process for remaining installation.8.
See Section 2.7, Re-charging, for re-charging information.9.
3.4 conDenSer
The condenser is a steel tube serpentine with copper alloy ns, which removes heat from hot, high pressure vapor from the
compressor. The most common trouble is lack of airow from either a restricted intake or exhaust opening in the front of the unit.
Lint, dust, hair, and dirt build-up needs to be removed from the condenser periodically to allow the unit to perform properly.
It is possible that the condenser might need replacement because of an unrepairable leak or a restriction that cannot be ushed
out. System high side pressures and temperatures will verify if this is the case.
Removing the Condenser:
1. Disconnect power, water line, and drain line. If a drain pump is used, it will need to be disconnected and removed.
2. Remove back panel and lower shroud (see Figure 3.1).
3. Remove the grill by removing the two or four screws (depending on the grill style) and disconnecting the three wires to
the rocker switch.
4. Remove the drain valve (see Section 4.1, Drain Valve).
5. Remove the water valve (see Section 4.2, Water Valve).
6. Take out the two screws that secure the top of the electrical bracket located in the front of the mechanical area (see
Figure 3.5).
7. Remove the six screws that secure the baseplate to the cabinet on the bottom of the unit (see Figure 3.5).
8. Gently slide the mechanical out the back of the unit enough to gain access to the condenser coil and fan shroud (see
Figure 3.6).
9. Install sealed system access valve(s) and recover refrigerant. After recovering, be sure to cap o the access valve to
prevent contamination of the system.
Remove the fan by removing the two nuts on the fan mounting bracket at the baseplate. The fan wire leads can be left con-10.
nected. Set the fan assembly to the side of the mechanical.
Remove the three nuts retaining the side of the fan shroud. Remove the fan shroud.11.
Unbraze the capillary tube from the drier assembly.12.
Unbraze the hot gas valve tube at the tee on the drier assembly (see Figure 3.1).13.
Unbraze and remove the drier assembly.14.
Unbraze the hot gas line from the compressor at the top of the condenser coil (see Figure 3.8).15.
Installing the Condenser:
Reverse the removal procedure (see above). Be sure to thoroughly ush the system and evacuate to 50 microns before weight
charging. If contamination was found or determined, the evaporator should also be replaced at this time.
