Refrigerant System Service Equipment: Notes

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. See Heating and Air Conditioning/Plumbing - Warning and Heating and Air Conditioning/Plumbing - Caution . Failure to follow these instructions may result in 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.
