Refrigerant: Tools and 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 the warnings and cautions may result in serious or fatal injury

WARNING: Eye protection must be worn when servicing an A/C refrigerant system. Turn all valves off (rotate clockwise) on the equipment being used before connecting or disconnecting service equipment from the refrigerant system. Failure to observe these warnings may result in serious or fatal injury.





When servicing the A/C system, a R-134a refrigerant recovery/recycling/charging station that meets SAE standard J2210 must be used (1). Contact an automotive service equipment supplier for refrigerant recovery/recycling/charging 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 system damage will result.

RECOVERY/RECYCLING/EVACUATION/CHARGING HOSE The center manifold hose (Yellow, or White, with Black stripe) (3) 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.

HIGH PRESSURE GAUGE HOSE The high pressure hose (Red with Black stripe) (4) attaches to the high side service port. This service port is located on the A/C liquid line between the A/C condenser and the A/C receiver/drier. On this model, an A/C pressure transducer is installed on the A/C receiver/drier. A/C high-side pressures can be read using a scan tool.

LOW PRESSURE GAUGE HOSE The low pressure hose (Blue with Black stripe) (5) attaches to the low side service port. This service port is located on the A/C suction line near the expansion valve at the dash panel.
