Refrigerant Recovery

REFRIGERANT RECYCLING
R-12 refrigerant is a chlorofluorocarbon (CFC) that can contribute to the depletion of the ozone layer in the upper atmosphere. Ozone filters out harmful radiation from the sun. To assist in protecting the ozone layer, Chrysler Motors recommends that an R-12 refrigerant recycling device that meets SAE standard J1991 be used when it is necessary to discharge the refrigerant system. Contact an automotive service equipment supplier for refrigerant recycling equipment that is available in your area. Refer to the 6perating instructions provided with the recycling equipment for proper operation.


DISCHARGING PROCEDURE

CAUTION: Review Safety Precautions and Warnings.

The air-conditioning refrigerant system is sealed and pressurized. The refrigerant system must not be opened for any reason until the system has been completely discharged. To discharge the refrigerant system,
1. Connect a suitable charging station or manifold gauge set.
2. Insert the discharge hose on the equipment being used into a refrigerant collection bottle/can that has a one inch Y cut into the plastic lid to retain the discharge hose).
3. Open suction (low pressure) valve slowly. Watch the discharge hose. If large amount of refrigerant oil is emitted, reduce the rate of discharge. If an excess amount of refrigerant oil has been discharged or the system is believed to be low on oil.
4. When the discharge (high pressure) gauge reads below 690 kPa (100 psi), slowly open the discharge valve.
5. When the suction and discharge gauges read 0, the refrigerant system is empty and should be safe to open. After the discharge procedure is complete, close the valves to avoid contaminating the refrigerant system.

CAUTION: To avoid system contamination, cap or tightly cover all open line ends or components while servicing the refrigerant system.
