1.9 Closing the Rear
Compartment
Ensure that the control wiring runs through the notches in the
plastic refrigerator body.
The refrigeration module and rear compartment of the cabinet
have adhesive strips and Permagum
1
(caulking cord sealant) pro-
tecting the components (Figures 1-9 and 1-8).
Ensure that all
adhesive strips and Permagum are still in place before
reassembly
.
CAUTION
The adhesive strips and Permagum are required to prevent air
flow between the condenser coil and the evaporator plate.
Without this protection, water condensation on the coil will
cause ice build-up, resulting in poor refrigerator performance
and inability to shut off.
Note
Two thick, black cables connect the power supply with the AC
and compressor (see Figure 1-8).
Ensure that these cables
are side by side and not crossed during reassembly.
