the tubing underneath.
22. Access the sealed system and discharge
the refrigerant into an approved recovery
system.

• Suction line at the compressor.
• Hot gas line at the hot gas valve.
• Cut capillary tube at the filter/drier.

REASSEMBLY NOTES:
• When installing the new evaporator, use a
generous amount of thermal heat trap paste
between the hot gas valve, and the evapo-
rator tubing joint to protect the hot gas valve
when brazing.
• Be sure to reinstall the Permagum in the
liner channel of the cabinet around the wire
sheath and tubing, so that there are no air
leaks after the cabinet top is installed (see
the photo in step 19 on page 4-13).
