Refrigerant Recovery and Recharging

Warning: To prevent personal injury, avoid breathing A/C Refrigerant and lubricant vapor or mist. Work in a well ventilated area. To remove refrigerant from the A/C System, use service equipment designed for recovery that is certified to meet the requirements of the appropriate SAE Standards. If an accidental system discharge occurs, ventilate the work area before continuing service. Additional health and safety information may be obtained from the refrigerant, refrigerant recovery, and lubricant manufacturers.

Caution: R-12 refrigerant and R-134a refrigerant must never be mixed, even in the smallest of amounts, as they are incompatible with each other. If the refrigerants are mixed, compressor failure is likely to occur. Refer to the manufacturer instructions included with the service equipment before servicing.

Note: For the use of the correct refrigerant oil, refer to electronic parts catalog.

The AC filling device is a complete air conditioning service center for R-134a. The AC filling device recovers, recycles, evacuates and recharges A/C refrigerant quickly, accurately and automatically. The unit has a display screen that contains the function controls and displays prompts that will lead the technician through the recover, recycle, evacuate and recharge operations. R-134a is recovered into and charged out of an internal storage vessel. The AC filling device automatically replenishes this vessel from an external source tank in order to maintain a constant volume of A/C refrigerant.

The AC filling device has a built in A/C refrigerant identifier that will test for contamination, prior to recovery and will notify the technician if there are foreign gases present in the A/C system. If foreign gases are present, the AC filling device will not recover the refrigerant from the A/C system.

The AC filling device also features automatic air purge, single pass recycling and an automatic oil drain.

Refer to the AC filling device manual for operation and setup instruction. Always recharge the A/C System with the proper amount of R-134a. Refer to Refrigerant System Capacities

A/C Refrigerant System Oil Charge Replenishing

If oil was removed from the A/C system during the recovery process or due to component replacement, the oil must be replenished. Oil can be injected into a charged system using GE-45037 injector . For the proper quantities of oil to add to the A/C refrigerant system, refer to Refrigerant System Capacities
