Refrigerant System Service Equipment
REFRIGERANT SYSTEM SERVICE EQUIPMENT
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 follow these instructions may result in serious or fatal injury.
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 serious or fatal injury.
NOTE: If equipped with the rear heating-A/C system, use a heat gun to heat the underbody lines to help remove any trapped refrigerant from the rear A/C system.
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.). 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.
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 top of the receiver/drier. This model is equipped with an A/C pressure transducer located on the A/C discharge line. A/C high-side pressures can be read using a scan tool Testing and Inspection.
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.
