Refrigerant Recovery & Recycling

ACR3 Hook Up:

DESCRIPTION
The refrigerant in the A/C system must be recovered using the air conditioning refrigerant recovery and recycling (ACR3) system J 38100-B (or equivalent). After repairing the malfunction, the refrigerant system can then be evacuated and charged using air conditioning service charging station J 23500-A or equivalent, or the manifold gage set J 23575-01 (or equivalent) and refrigerant.

Evacuation lines from the recovery system and the charging lines from the charging station or manifold gage set require the use of adapters to connect to the A/C system low-side service fitting. A straight adapter J 5420 and a 900 adapter J 9459 (or equivalent) are available.

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

PROCEDURE
1. Start vehicle and run with A/C on for two minutes, then 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.

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" lamp illuminates and the compressor starts. The compressor shuts off automatically when recovery is complete. Wait two minutes and check for pressure rise. If pressure rise occurs, depress the "Compressor Start" switch and repeat the recovery.

5. To drain the accumulator of A/C system oil, open the "Accumulator Pressurizing" valve long enough 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. Measure drained refrigerant oil. Replenish whatever necessary.

6. Although refrigerant can be filtered and recycled at any time, recycling is recommended 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.

RECYCLING
When the recovery tank is full, the "Trip Switch" at the bottom of the weight platform de-energizes the compressor and the "Tank Full" lamp comes on. Close both tank valves, remove the tank from the platform, and replace with another refillable tank, or recycle the first tank. If the first tank is not immediately recycled, take precautions to prevent its use in charging A/C systems BEFORE it is recycled. Additional tanks are available.
