NOTE:
All inoperative compressors returned to
Friedrich must have all lines properly
plugged with the plugs from the
replacement compressor.
REFRIGERANT CHARGE
1. The refrigerant charge is extremely critical.
Measure the charge carefully and as exactly
as possible to the nameplate charge.
2. The correct method for charging the rotary
is to introduce liquid refrigerant into the high
side of the system with the unit off. Then
start the compressor and enter the balance
of the charge, gas only, into the low side.
The introduction of liquid into the low side,
without the use of a capillary tube, will
cause damage to the discharge valve of the
rotary compressor.
ROTARY COMPRESSOR SPECIAL
TROUBLESHOOTING AND SERVICE
Basically, troubleshooting and servicing
rotary compressors is the same as on the
reciprocating compressor with only a few
exceptions.
1. Because of the spinning motion of the rotary,
the mounts are critical. If vibration is
present, check the mounts carefully.
2. The electrical terminals on the rotary are in a
different order than the reciprocating
compressors. The terminal markings are on
the cover gasket. Use your wiring diagram
to insure the correct connections.
