Condensor; Removing The Condenser - Viking VUIM/DUIM150 Service Manual

Service Diagnostics and Procedures
Compressor Installation
1. Install the four rubber grommets in the bottom
of the new compressor and install the two
sleeves where the carriage bolts will be located.
Mount the new compressor and install the three
washers and lock nuts and tighten to 45 in-lbs.
DO NOT REMOVE RUBBER PLUGS AT THE
TUBE STUBS ON THE COMPRESSOR AT THIS
TIME.
2. Install and braze new drier assembly to
condenser. Install and braze capillary tube and
hot gas valve tube.
3. Remove the plug for the hot gas line at the
compressor. Install and braze the hot gas line to
the compressor.
4. Remove the plug for the process tube on the
compressor. Install and braze in the process
tube. Be sure to cap off the end to prevent any
contamination.
5. Remove the plug for the sution line on the
compressor. Install and braze in the suction line
from the evaporator. BE SURE TO REINSTALL
THE SUCTION LINE AND TUBING HARNESS
INSULATION TUBES.
6. Reinstall compressor overload and then the
starter.
7. Reinstall compressor cap.
8. Reverse steps 1 through 7 of removal process
for remaining installation.
9. See page 16, Re-charging, for re-charging
information.

Condenser
The condenser is a steel tube serpentine with
copper alloy fins, which removes heat from hot,
high pressure vapor from the compressor. The
most common trouble is lack of airflow 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
replaced because of an unrepairable leak or a
restriction that cannot be flushed 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 4).
3. Remove the grille by removing the two screws
and disconnecting the three wires to the rocker
switch.
4. Remove the drain valve (see page 25,
Drain Valve).
5. Remove the water valve (see page 26, Water
Valve).
6. Take out the screw that secures the top of the
electrical bracket located in the front of the
mechanical area (see Figure 8).
7. Remove the six screws that secure the
baseplate to the cabinet on the bottom of the
unit (see Figure 8).
8. Gently slide mechanical out back of unit enough
to gain access to condenser coil and fan shroud
(see Figure 9).
9. Install sealed system access valve(s) and recover
refrigerant. After recovering, be sure to cap
off access valve to prevent contamination of
system.
