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.
Warning: For personal protection, goggles and lint-free gloves should be worn and a clean cloth wrapped around fittings, valves, and
connections when doing work that includes opening the refrigerant system. If refrigerant comes in contact with any part of the body severe
frostbite and personal injury can result. The exposed area should be flushed immediately with cold water and prompt medical help should
be obtained.
Caution: R-134a is the only approved refrigerant for use in this vehicle. The use of any other refrigerant may result in poor system
performance or component failure.
Caution: To avoid system damage use only R-134a dedicated tools when servicing the A/C system.
Caution: Do not mix refrigerant oils. Use of incorrect refrigerant oil will cause compressor failure.
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.
