Refrigerant System Service Equipment

REFRIGERANT SYSTEM SERVICE EQUIPMENT

WARNING: Refer to the applicable warnings and cautions for this system before performing the following operation Warning and Caution . Failure to follow these instructions may result in possible serious or fatal injury.

WARNING: Eye protection must be worn when servicing an air conditioning refrigerant system. Turn off (rotate clockwise) all valves on the equipment being used, before connecting to or disconnecting from the refrigerant system. Failure to follow these instructions may result in possible serious or fatal injury.





When servicing the A/C system, use an R-134a refrigerant recovery/recycling/charging station (1) that meets SAE standard J2788. Per SAE standard J2788, refrigerant recovery stations must recover 95% of the refrigerant system within 30 minutes at 21.1° C (70° F) and be able to measure the amount of refrigerant removed from the system to an accuracy of 28 grams (1 oz.). When charging, the refrigerant recovery station must charge the system to an accuracy of 14 grams (0.5 oz.). Contact an automotive service equipment supplier for refrigerant recovery/recycling/charging equipment. See the operating instructions supplied by the equipment manufacturer for proper care and use of this equipment.





A manifold gauge set (1) may be needed with some recovery/recycling/charging equipment. The manifold gauge set should have manual shut-off valves (2 and 6) or automatic back-flow valves located at the service port connector end of the manifold gauge set hoses (4 and 5). This will prevent refrigerant from being released into the atmosphere.

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 A/C system damage will result.

- LOW PRESSURE GAUGE HOSE - The low pressure hose (Blue with Black stripe) attaches to the low-side service port. This port is located on the A/C suction line near the rear of the engine compartment.
- HIGH PRESSURE GAUGE HOSE - The high pressure hose (Red with Black stripe) attaches to the high-side service port. This port is located on the A/C liquid line near the front of the engine compartment.
- RECOVERY, RECYCLING, EVACUATION AND 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.
