MANIFOLD GAUGE SET CONNECTIONS
CAUTION: Do not use an R-12 manifold gauge set
on an R-134a system. The refrigerants are not compatible
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 liquid line
near the evaporator inlet tube at the rear of the
engine compartment.
HIGH PRESSURE GAUGE HOSE The high pressure
hose (Red with Black stripe) attaches to the discharge
service port. This port is located on the
manifold directly over the discharge port of the compressor.
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 pressure valves on the manifold gauge set
are opened, the refrigerant in the system will escape
through this hose.
