D - Refrigeration System
5. Disconnect cap tube from evaporator.
Flush evaporator in same manner as
condenser.
CAUTION
DO NOT exceed 150 PSIG.
6. Flush cap tube. This is only possible if you
have proper service valve adaptor.
CAUTION
DO NOT exceed 300 PSIG.
7. Reassemble system.
To Use Refrigerant To Flush The System:
CAUTION
Refrigerant used for flushing must be
recovered into a recovery system. Meter
amount of refrigerant used for flushing with
your charging cylinder. DO NOT OVERFILL
THE BAG.
1. Disconnect the suction and discharge lines
from the compressor and remove the filter-
drier. Connect process coupling to outlet
and inlet tube of condenser.
2. Connect hose to outlet process coupling
and charging cylinder. Connect another
hose to inlet coupling and recovery system.
3. Open charging cylinder and allow
refrigerant to flow through condenser until
discharge into bag is clear.
NOTE
To flush evaporator and heat exchanger you
must remove evaporator from inside product to
disconnect cap tube.
4. Disconnect capillary tube from evaporator.
Flush evaporator in same manner as
condenser.
5. Flush cap tube. This is only possible if you
have proper service valve adaptor.
6. Reassemble system.
Replacement of compressor and installation of
filter-drier must be done in a continuous sequence
so system is exposed to atmosphere no longer
than necessary.
All replacement compressors are shipped with
rubber plugs in the suction, discharge and process
tubes and contain the correct oil charge and a
holding charge of inert gas. Compressors have a
low-side process tube attached to the compressor
shell. A high-side process tube is attached to the
filter-drier.
WARNING
Do not operate reciprocating compressor
when charging liquid refrigerant into system
through its process tube.
Replacement compressors for refrigerator may
have an oil cooler even if the original compressor
did not. If the product is not equipped for an oil
cooler, leave the plastic caps in place and install
the compressor connecting only to the suction and
discharge lines of the new compressor.
Before installing the replacement compressor
remove the discharge plug and check for the pop
sound of the inert gas leaving the compressor.
If the compressor checks OK, reinstall the plug.
Do not remove any of the plugs again until the
compressor is in position and you are ready to
braze the lines.
CAUTION
DO NOT use compressor if you do not
hear this sound.
CAUTION
On R-134a systems, compressor must NOT
be left open to atmosphere for more than 10
minutes to prevent moisture contamination of
oil.
NOTE
Entirely new compressors have been developed
for use with R-134a and Ester oil refrigeration
systems. Both compressor and electric motor
have been modified. Old compressors intended
for R-12 refrigerant must not be used for new
systems charged with R-134a.
