Reinstalling Compressor - Continued
Replace high pressure control tubing.
Replace low pressure control tubing and rewire to junction box making certain that the posts are in
good condition and maintaining proper contact between these posts and the connecting wires.
Replace the compressor conduit fasteners.
Draw suction with vacuum pump to 29.8" absolute. Maintain vacuum for at least one (1) hour.
Backseat suction and discharge service valves.
Pressure test connections at suction and discharge service valves using refrigerant gas detector.
Connect suction and discharge service gauges.
Operate air conditioner and observe compressor operating pressures and conditions.
10) Add refrigerant if necessary, DO NOT OVERCHARGE.
Compressor Oil Level, Lubrication and Oil Addition On this unit, oil may be added by attaching a charging
manifold to the gauge port on the suction valve and putting a 1/4" copper tube to the center connection of the
charging manifold well down into a container of refrigerant oil. With a positive pressure on the gauge, open the
hand valve momentarily to purge the copper tube of air, then close the suction shut off valve to suck in oil from
container slowly until proper level is visible in the sight glass.
