NOTE: To remove any sealed system component from a Model ICB424, the unit must be pulled from its installation.
NOTE: If removing a model ICB424 from its installation, an anti-tip bracket and a countertop bracket may have
been used to make a solid installation.
NOTE: Always replace the refrigerant valve assembly (which includes the filter-drier), when servicing a wine storage
sealed system.
Evaporator Assembly Removal (Model ICB424)
The evaporator assembly consists of the evaporator
and heat exchanger. One evaporator is mounted to the
rear wall in each compartment. The heat exchangers
are routed out the back wall, down to the unit tray
where the capillary tubes are attached to each side of
the refrigerant valve assembly, and the suction tubes
are attached to a tubing T-connector with it's outlet run-
ning to the compressor suction port.
To remove an evaporator assembly
6-23, 6-24, & 6-25):
1. Evacuating refrigerant from sealed system.
2. With a tin snips, or similar tool, cut heat exchanger
in compartment as close to back wall as possible,
then pull evaporator from compartment.
3. At back of unit, remove lower access panel and
heat exchanger duct cover.
4. At bottom of unit, remove door closer and screws
securing unit tray to cabinet on the left side, loosen
the screws on right side.
5. Separate cabinet from unit tray by leaning cabinet
to the right, then insert a spacer between cabinet
and unit tray (a piece of 2x4 lumber works well).
6. With a tube-cutter, cut the appropriate suction tube
from the T-connector and the filter-drier from con-
denser outlet.
7. At refrigerant valve assembly, use a file to score a
line around capillary tube of opposite heat exchang-
er, 1" or less from valve outlet, then fatigue capillary
tube at this line until it separates.
NOTE: After capillary tube separates, check tubing
for internal burrs. If burrs exist, repeat step above.
8. Remove heat exchanger being replaced and refrig-
erant valve assembly.
NOTE: After new evaporator assembly is installed, the
tubing channel must be sealed closed with silicone.
