SEALED SYSTEM COMPONENTS
Upper Refrigerator Compartment Evaporator
Removal (All Models except 700TF/I-3)
The upper evaporator is attached to the back wall with
screws.
NOTE:
Before attempting to remove the evaporator,
evacuate the refrigerant from the sealed system.
To access and remove the upper evaporator, first
remove the light diffuser and evaporator cover, then (See
Figure 7-44):
1.
Extract screws securing evaporator to the back
wall.
2.
With a tube cutter, cut inlet tube approximately one
inch from the end and cut the outlet tube approxi-
mately two inches from the end.
NOTE:
Sweating the joints apart is not recommended
as this may induce moisture into the sealed system and
could cause a solder restriction in the capillary tube.
NOTE:
When installing a new evaporator, be sure to
thoroughly clean the tubing before brazing. After brazing
and inspecting the joint for leaks, it is recommended to
apply an acrylic-based paint to the joints to protect the
exposed metals from oxidation.
Lower Compartment Evaporator Removal
The lower evaporator is attached to the back wall with
screws.
NOTE:
Before attempting to remove the evaporator,
evacuate the refrigerant from the sealed system.
To access and remove the lower evaporator, first remove
the heat exchanger cover, evaporator cover and switch
enclosure. In the model 700TC/I-3 & 736TC/I-3, the
evaporator fan shroud will also need to be removed, then
(See Figure 7-45):
1.
Extract screws securing evaporator to back wall.
2. With a tube cutter, cut the inlet tube approximately
one inch from the end and cut the outlet tube
approximately two inches from the end.
NOTE:
Sweating the joints apart is not recommended
as this may induce moisture into the sealed system and
could cause a solder restriction in the capillary tube.
NOTE:
If reusing the existing defrost heater, defrost ter-
minator and evaporator thermistor, they can be removed
from the evaporator after it is removed from the unit.
