13. Connect the capillary tube to the inlet tube
of the evaporator. Connect the
OD copper tube to the outlet tube of the
evaporator (remove any excess length as
required to obtain the correct fi t).
14. Apply a liberal amount of thermal paste
around both epoxy joints to prevent heat
from damaging joint integrity.
15. Install a metal brazing shield between the
joints and the plastic liner.
16. Protect the freezer floor from molten solder
during brazing.
17. Angle torch so that the fl ame is directed
away from the plastic liner. Braze both
joints. Clean and inspect joints. Remove the
brazing shield.
18. Clean thermal paste off the joints. Dress the
joints to the right of the freezer evaporator
so the freezer evaporator cover can be
reinstalled without interference.
19. Reinsert the thermistor into the aluminum
block on the rear of the new fresh food
evaporator.
20. Attach the evaporator to the fresh food liner
using the original screws. Ensure that the
drain pan is properly positioned. Install a
new Styrofoam block into the hole of the
mullion. Attach foam tubes to evaporator
inlet/outlet tubes using wire tie provided.
21. Remove the old drier by cutting the con
denser loop as close as possible to the
drier. Install the new drier assembly, making
sure that there is suffi cient space between
the tubing. Install the access tube on the
compressor.
22. Evacuate and charge the system. Use
original factory charge quantity of R-134a.

Evacuation and Charging Procedure
23. Replace all component parts in both the
freezer and the fresh food compartments.
24. Reinstall the rear access cover.
