Refrigerant Recovery

ACR Hook Up:

The refrigerant system must be discharged using an Air Conditioning Refrigerant and Recycling System J 38100-C. After repairing the malfunction the refrigerant system can then be evacuated and charged using air conditioning service charging station J 23500-01 or equivalent, or the manifold and gage set J 23575-01 and refrigerant.

Evacuation lines from the recovery system and the charging lines from the charging station or manifold and gage sets require the use of adapters to connect to the A/C system low-side service fining. A straight adapter J 5420 and a 90° adapter J 9469 are available.


NOTE: Failure to check for residual oil from the previous recovery can result in adding extra oil to the current vehicle being serviced. This will result In reduced performance and possible compressor damage.


1. Start the vehicle and run with the A/C on for 2 minutes and then turn engine off. Attach a manifold gage set to the A/C system and attach the recovery station inlet hose to the center fitting of the manifold gage set (see accompanying figure).

2. Open both valves of the manifold gage set. Make certain the refrigerant tank "Vapor" valve and the "Liquid" valve are open.

3. Plug the station into a suitable AC power outlet and turn on the "Main Power" switch.

4. Depress the "Compressor Start" switch. The amber "Compressor On" light will come on and the compressor will start. The compressor will shut off automatically when recovery is complete. Wait 2 minutes and check for pressure rise. If pressure rise occurs depress '4Compressor Start" switch and allow to repeat the recovery.

5. To drain the accumulator of refrigerant system oil, open the "Accumulator Pressurizing" valve for 15 seconds to allow some compressor discharge pressure back into the accumulator. Open the oil drain valve slowly and drain the accumulator. When the oil stops draining, close the oil drain valve. Do not allow the accumulator to completely depressurize.

6. Although refrigerant can be filtered and recycled at any time, it is recommended to recycle when the tank is full for greatest efficiency. Two tanks are provided so you can fill one, recycle it, and use it for charging systems while filling the second tank.

NOTE: When the recovery tank is full, the "Trip Switch" at the bottom of the weight platform will de-energize the compressor and the "Tank Full' light will come on. Close both valves, remove the tank from the platform, and replace with another refillable tank or recycle the first tank. If the first tank isn't immediately recycled take precautions to prevent its use in A/C systems BEFORE it is recycled. Additional tanks (part number J 38100-30) are available, see the "Replacement Parts" section of your operators manual.
