CONNECTING GAUGES
To connect service gauges to the access service ports, remove the protective sealing caps from the service ports on the DC 5000. Note that the ports are of different sizes. The larger diameter port is the discharge side and the smaller port is the suction side. Pull back the collar on the connecting valve and push it over the appropriate access port.
IMPORTANT: There may be a variation in the interface (depending on the brand of service valve being used) between the connecting valve and the service port core valve.
It is important to open each connecting valve carefully. Do not force the connecting valve or turn it to it's stop. Forcing the connecting valve will bend the service port core valve creating a leak.
Turn the connecting valve clockwise to open. During the service operation these valves are left open. Control of refrigerant and vacuum is by the manifold hand wheels.
TO INSTALL GAUGES ON AN UNCHARGED SYSTEM to be evacuated no purging or venting is needed.
TO INSTALL GAUGES ON A CHARGED SYSTEM, with the system off, attach the connecting valves to the service ports. Proceed to Venting the Gauge Set.
DISCONNECTING GAUGES
Disconnecting the gauge set after running the system may be done by turning off the discharge connecting valve first. Remove the connecting valve and
Disconnecting the gauge set on a static system may be done by turning off the connecting valves and disconnecting them from the access service ports.
