Component Access / Removal
Refrigerant Valve Assembly (Includes Filter-Drier)
Removal (Model ICB424)
The refrigerant valve assembly is secured to the valve
bracket with screws.
To access the refrigerant valve assembly, the unit will
need to be pulled from its installation.
NOTE: If removing a model ICB424 from its installa-
tion, an anti-tip bracket and a countertop bracket may
have been used to make a solid installation.
With unit out of installation
1. Remove access panel from bottom back of unit and
door closer from bottom front corner.
2. Extract screws securing unit tray to cabinet on the
left side, and loosen screws on right side.
3. 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).
4. With a tube-cutter, cut filter-drier inlet.
5. At refrigerant valve assembly, use a file to score a
line around the capillary tubes, 1" or less from valve
outlets, then fatigue capillary tubes at this line until
they separates.
NOTE: After capillary tube separates, check tubing
for internal burrs. If burrs exist, repeat step above.
Compressor Removal (Model ICB424)
The compressor is located at the back of the unit tray.
To access the compressor, the unit will need to be
pulled from its installation.
NOTE: If removing a model ICB424 from its installa-
tion, an anti-tip bracket and a countertop bracket may
have been used to make a solid installation.
