Warning
|
|
To prevent personal injury, avoid breathing A/C Refrigerant and lubricant vapor or mist. Work in a well ventilated area. When removing 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 with the 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 lint free 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.

|
Warning
|
|
You must replace the desiccant if the A/C refrigerant system has been open to atmosphere for more than four hours, or if the A/C refrigerant oil has been contaminated. Failure to replace the desiccant will result in damage to the A/C refrigerant system.

|
|
|
Warning
|
|
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 and potentially void the vehicle warranty for the refrigerant system.
|
|
|
|
|
|
|
Warning
|
|
To avoid system damage use only R-134a dedicated tools when servicing the A/C system.
|
|
|
|
|
|
|
Warning
|
|
Do not lubricate A/C line seal washers as mineral oil will damage the seal and cause leaks. Use only 525 viscosity mineral oil to lubricate o-rings as well as fitting threads for the prevention of fitting seizure.
|
|
|
|
|
|
|
Warning
|
|
Use only GM approved Polyalkylene Glycol Synthetic Refrigerant Oil (PAG) for internal circulation through the R-134a A/C system.

Both the
J-43600
ACR 2000 Air Conditioning Service Center and
GE-48800
CoolTech A/C Recharge Machine are complete air conditioning service center for R-134a. Both units recovers, recycles, evacuates and recharges A/C refrigerant quickly, accurately and automatically. Both units have 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. Both units automatically replenishes this vessel from an external source tank in order to maintain a constant 5.45-6.82 kg (12-15 lbs) of A/C refrigerant.
The ACR 2000 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 ACR 2000 will not recover the refrigerant from the A/C system.
The ACR 2000 also features automatic air purge, single pass recycling and an automatic oil drain.
The
GE-48800
CoolTech A/C filling machine has been introduced as a necessary replacement for the previous important
J-43600
ACR 2000 Air conditioning, service center. The
GE-48800
CoolTech A/C filling machine complies with SAE J2788 and meets GM:s requirements for the repair of A/C refrigerants on all GM vehicles, including hybrid systems with polyolester (POE) refrigerant oil.
Refer to the
J-43600
ACR 2000 Air Conditioning Service Center or
GE-48800
CoolTech A/C Recharge Machine manual for operation and setup instruction. Always recharge the A/C System with the proper amount of R-134a. Refer to
Refrigerant System Specifications
for the correct amount.
|
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 same quantity of PAG oil must be replenished. If no oil was removed from the A/C system during recovery, do not charge any PAG oil into the A/C system. Oil can be injected in a filled system with the
J-45037
A/C Oil Injector. For the correct amount of oil so be added to the A/C refrigerant system, refer to
Refrigerant system, specifications
.
