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: 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.
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: Use only Polyalkylene Glycol Synthetic Refrigerant Oil (PAG) for internal circulation through the R-134a A/C system and only 525 viscosity
mineral oil on fitting threads and O-rings. If lubricants other than those specified are used, compressor failure and/or fitting seizure may result.
The J 34100 - Smart Cart is a complete air conditioning service center for R-134a. The Smart Cart 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
ACR 2000 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 Smart Cart 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 Smart Cart will not recover the refrigerant from the A/C system.
The Smart Cart also features automatic air purge, single pass recycling and an automatic oil drain.
Refer to the J 34100 - Smart Cart Smart Cart manual for operation and setup instruction. Always recharge the A/C System with the proper amount of
R-134a. Refer to Refrigerant System Specifications (See: Heating and Air Conditioning/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 oil must be replenished.
