Evaporator and Suction line
Replacement
To replace the heat exchanger:
The original heat exchanger (suction line and
cap tube assembly) in this product is enclosed in
the insulation between the liner and the cabinet
back. Because of this, the original part cannot
be removed. There is a service kit to bypass the
internal heat exchanger. It will be necessary to
run a new heat exchanger down the back of the
product and bypass the internal heat exchanger.
CAUTION
Always use the TORCHGUARD heat shield
behind evaporator before attempting to solder.
The excessive heat from soldering will warp the
plastic liner.
