SERVICE INFORMATION

Several states and communities currently prohibit the discharging of ozone-depleting chlorofluorocarbons (CFC's), including A/C refrigerant Freon R-12 and Freon R-12, into the environment.

In addition, the federal Clean Air Act prohibits discharging of CFC's into the environment on a nationwide level, beginning January, 1992 (January, 1993 in certain instances).

To ensure that A/C system servicing is performed in accordance with these regulations, A/C refrigerant must only be discharged using an Underwriter's Laboratory (UK) approved refrigerant recovery/ recycling unit such as Kent-Moore ACR3, or equivalent.

WARNING: Automotive refrigerant containing CFC's is hazardous to the earth's atmosphere. To protect our environment, use a refrigerant recovery/recycling unit (even if not yet required by law in your area) whenever discharging an A/C system.

A/C REFRIGERANT SYSTEM, DISCHARGING

The following procedure supersedes all previous A/C discharging information.

WARNING: The A/C system should be serviced only by trained personnel familiar with:

Equipment use
Related safety procedures
Regulations governing the discharging/handling/disposal of automotive refrigerants.

CAUTION: Always follow manufacturer's instructions when using a refrigerant recovery/recycling unit.

- Close both valves on A/C manifold gauge set.

- Connect manifold gauge low pressure hose -1- to A/C low pressure service valve on vehicle. See Fig 1 .

- Connect manifold gauge high pressure hose -3- to A/C high pressure service valve on vehicle. See Fig 1 .

- Connect manifold gauge hose -2- to inlet connection -4- on refrigerant recovery/recycling unit -5-. See Fig 1 .

- Following refrigerant recovery/recycling unit manufacturer's instructions, discharge A/C system into refrigerant recovery/recycling unit.
