HOOK-UP FOR SYSTEM DIAGNOSIS
To properly diagnose the problem in the A/C system, first check the
system's overall performance. This includes testing the system's pressure and
refrigerant flow. The system pressure can be checked with the manifold gauge
set.
NOTE: Be sure that the hand valves on the manifold gauge set are in the
closed position. Always wear gloves and safety goggles when working with
refrigerant.
1. Remove the protective caps from the system ports. Check for leaks at the
ports.
2. Connect the Low side service hose (Blue) to the suction side of the
compressor. Connect the High side service hose (Red) to the discharge side of
the compressor. Make sure the couplers are securely snapped.
3. If using manual couplers, move the plunger down within the coupler by turning
the knob clockwise in order to open the port valves and start refrigerant flow.
