REFRIGERANT RECYCLING
(R-12) refrigerant is a chlorofluorocarbon (CFC)
that can contribute to the depletion of the ozone
layer in the upper atmosphere. To help protect the
ozone layer, an R-12 recycling device must be used.
Contact an automotive service equipment supplier
for refrigerant recycling equipment. Refer to the op-
erating instructions provided with the recycling
equipment for proper operation.
MANIFOLD GAUGE SET CONNECTIONS
GENERAL INFORMATION
The high pressure (discharge) (RED) hose should
be attached to the 1/4 in. discharge service port. This
port is located on the discharge line between the A/C
compressor and the condenser, or on the high pres-
sure (liquid) line. The low pressure (suction) (BLUE) hose should be
attached to the 3/8 in. suction service port. This port
is located on the air conditioning compressor, or the
suction line between the expansion valve and the
compressor.
SUCTION (LOW PRESSURE) GAUGE CONNECTION
(1) Remove the service port cap from 3/8 in. suc-
tion service port. (2) Check all valves on the equipment being used
to verify they are closed. (3) Inspect the hose gasket in the service port con-
nector at the end of the (BLUE) hose. If the gasket is
flawed, replace it. (4) Thread the hose connector onto the service
port. Quickly secure hose connector to the service
port to avoid loosing refrigerant. To disconnect suction gauge (BLUE) hose:(a) Wrap the end of hose with a shop towel.
(b) Loosen the hose connector.
(c) Push and hold the end of hose toward the ser-
vice port to keep the gasket in contact with service
port. (d) Quickly rotate the connector counterclock-
wise. When the hose connector is completely
