(a) The ends of discharge and suction tubing on a new compressor may be crimped to seal

in refrigerant charge. The tubing ends on the compressor will have to be cut and

swagged if the ends are crimped.

(b) If the tubing ends on new compressor are already swagged (4, FIGURE 3-18) and

plugged, remove plugs (3) to release charge and continue with step h(2)(d) of this

procedure.

refrigerant charge from the compressor.

CAUTION

Keep compressor in an upright position after opening seal. A new compressor will

already have the proper amount of oil added. If compressor is tipped, oil will be

lost by draining from the open discharge or suction line connection.

(d) Using the swagging tool (1, FIGURE 3-18) from the refrigerant tool kit, swag the tubing

ends (4) and (8) on the new compressor to proper size so that the suction line and

discharge line will fit.

(e) Position new compressor (2) on unit and install mounting bolts with rubber mounts (6).

(f) Make sure the connections are free of dirt and grease.

(g) Position the end of discharge tubing (13, FIGURE 3-17) to be connected into the

swagged fitting on the end of compressor discharge tubing.

(h) Position the end of suction tubing (14) to be connected into the swagged fitting on the

end of compressor suction tubing.

CAUTION

Do not let solder or debris enter compressor line openings.

(i) Solder each joint to connect discharge and suction line tubings.

(j) Connect electrical wiring to proper terminals on compressor.
