7. Use 1/4” drill bit to drill hole through cabinet from
inside at location shown in Figure 2.
8. Use 1/2” drill bit to open hole drilled in Step 7 to
1/2” from back of product. (See Figure 2.)
9. Remove stubs of old heat exchanger from evapora-
tor and install new heat exchanger into evaporator.

HEAT EXCHANGER REPLACEMENT
CAUTION: Always use the TORCH GUARD
heat shield behind evaporator before attempt-
ing to solder. The excessive heat from solder-
ing will warp the plastic liner.
The original heat exchanger (Suction Line & Cap Tube
Assembly) in this product is enclosed in the insulation
between the liner and the cabinet back. Because of this,
the original part can not 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
