To install the new cable assembly:
1. Feed the connector end of the new cable through the
threaded opening from the rear of the cabinet.
2. Apply a coating of the clear silicone sealant (such as Dow
Corning 737 RTV) to the threads of the cable's bulkhead
fitting.
3. Screw the bulkhead fitting into the cabinet wall until the
threads bottom out. Smooth the excess silicon sealant
around its base to seal the joint.
4. Tighten the black plastic cord-grip fitting over the bulk-
head fitting.
5. Clean the control panel's mounting surface on the face of
the refrigerated compartment. This will help ensure that
the gasket will seal the enclosure.
