STANDARD PROCEDURE - REFRIGERANT
SYSTEM SERVICE EQUIPMENT
WARNING: EYE PROTECTION MUST BE WORN
WHEN SERVICING AN AIR CONDITIONING REFRIG-
ERANT SYSTEM. TURN OFF (ROTATE CLOCKWISE)
ALL VALVES ON THE EQUIPMENT BEING USED,
BEFORE CONNECTING TO OR DISCONNECTING
FROM THE REFRIGERANT SYSTEM. FAILURE TO
OBSERVE THESE WARNINGS MAY RESULT IN PER-
SONAL INJURY.
When servicing the air conditioning system, a
R-134a refrigerant recovery/recycling/charging sta-
tion that meets SAE Standard J2210 must be used.
Contact PSE or an automotive service equipment
supplier for refrigerant recovery/recycling/charging
equipment. Refer to the operating instructions sup-
plied by the equipment manufacturer for the proper
care and use of this equipment.
A manifold gauge set may be needed with some
recovery/recycling/charging equipment (Fig. 1). The
service hoses on the gauge set being used should
have manual (turn wheel), or automatic back-flow
valves at the service port connector ends. This will
prevent refrigerant from being released into the
atmosphere.
MANIFOLD GAUGE SET CONNECTIONS
CAUTION: Do not use an R-12 manifold gauge set
on an R-134a system. The refrigerants are not com-
patible and system damage will result.
LOW PRESSURE GAUGE HOSE
The low pressure hose (Blue with Black stripe)
attaches to the suction service port. This port is
located on the compressor manifold, directly over the
suction port of the compressor.
HIGH PRESSURE GAUGE HOSE
The high pressure hose (Red with Black stripe)
attaches to the discharge service port. This port is

RECOVERY/RECYCLING/EVACUATION/CHARGING
HOSE
The center manifold hose (Yellow, or White, with
Black stripe) is used to recover, evacuate, and charge
the refrigerant system. When the low or high pres-
sure valves on the manifold gauge set are opened,
the refrigerant in the system will escape through this
hose.
