Heat Exchanger
The upper heat exchanger passes through the ceiling in
the upper compartment and the lower heat exchanger
passes through the back wall in the lower compartment.
NOTES:
• Whenever servicing the sealed system, the refriger-
ant valve assembly (which includes the filter-drier)
MUST
be replaced.
• It will be necessary to pull the unit from its installation
and remove the rear duct in order to replace the
lower heat exchanger. See WARNINGS at beginning
of this section.
To remove a heat exchanger, first capture the refriger-
ant from the sealed system, then (See Figure 6-38):
1. Extract evaporator mounting screws, then pull and
rotate evaporator so heat exchanger is accessible.
2. With a file, score a line around capillary tube, 1” or
less from evaporator inlet, then fatigue capillary
tube at this line until it separates.
3. With a tube-cutter, cut suction tube 1” or less from
evaporator outlet stub, then remove evaporator
from compartment.
4. With a tin snips, or similar tool, cut heat exchanger
in compartment as close as possible to ceiling or
wall where heat exchanger passes through.
5. Use a tube-cutter to cut drier from condenser outlet
tube.
6. Using a tube cutter, cut suction line approximately
1” from compressor.
7. Pull remaining heat exchanger from unit.
NOTES:
• Do not sweat tubing apart. Doing so will induce
moisture into the sealed system.
• When replacing the heat exchanger, it is recommend-
ed to attach it at the evaporator end first, then feed
the heat exchanger through hole, up to compressor
area.
