Heat Exchanger (All Models except 601's)
NOTE: When replacing a heat exchanger, the filter-
drier must also be replaced.
NOTE: It is necessary to pull a model 611-2, 611G-2,
650-2 and 650G-2 from its its installation in order to
replace a freezer heat exchanger. For all other models,
it is not necessary to the unit from its installation in
order to replace a freezer heat exchanger.
After capturing the refrigerant from the sealed system
(See Figures 7-163, 7-164, 7-165):
1. Extract screws which hold evaporator.
2. Pull and rotate evaporator so heat exchanger is
accessible.
3. 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.
4. With a tube-cutter, cut evaporator outlet 1" or less
from accumulator (if applicable), or 1" or less from
suction line connection point.
5. With a tin snips, or similar tool, cut heat exchanger
in compartment as close as possible to wall or ceil-
ing where heat exchanger passes through.
6. In upper compressor area, use a tube-cutter to cut
drier from condenser.
7. Extract nuts from stud-bolts at each corner of com-
pressor base.
8. Lift compressor up and pull forward to gain access
to suction line.
8. Using a tube cutter, cut suction line approximately
1" from compressor.
9. Pull remaining heat exchanger from unit.
NOTE: It is not recommended to sweat tubing apart.
Doing so will induce moisture into the sealed system.
NOTE: When replacing the heat exchanger, it is recom-
mended to attach it at the evaporator end first, then
feed the heat exchanger through hole, up to compres-
sor area.
