APPLICATIONS
1. The Red HP Gauge (3) is used to measure high pressure compressor discharge side pressure.
2. The Blue LP Gauge (5) is used to measure low-pressure side suction or pressure.
3. The Manifold Valves (11) control the flow of refrigerant to and from the Yellow Hose (18), also called the Charge Hose.
4. The Coupler Valves (22,23) control the flow to the Gauges (3, 5) from the Red and Blue Hoses (17,19).
5. The Sight Glass (13) allows checking the appearance of the refrigerant.
6. The Yellow Hose (18), also called Charge Hose can be used three ways:
a. Refrigerant recovery/evacuation.
b. Charging (filling) the system.
c. For checking, attach the Yellow Hose (18) to both branches of the T-fitting (16) to reduce the risk of leaks.
7. The charge valve allows for simultaneous connection of a refrigerant recovery system.
8. General instructions for A/C service are outlined in this manual. Specific procedures for each individual system type
and model should be referenced in the vehicle manufacturer’s specific A/C system service manual.
9. See Operation instructions that follow.
