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 pressure (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. suction 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 connector 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 service port to keep the gasket in contact with service port.

(d)Quickly rotate the connector counterclockwise. When the hose connector is completely
