A. Initial System Operation and Preparation

1. Review the Component Chart and installation notes attached to determine the parts required for the particular vehicle being adapted.

2. If the system is functioning properly, proceed to step A3. If the system is not functioning, determine the cause. If the system has no charge, charge the system to 50 psi with R-12 refrigerant. Identify any leaks and/or failed components. If the system is still not functioning, proceed to Step A4.

3. Operate the A/C system at engine idle speed for 15 minutes on high blower speed and outside air mode to maximize the oil in the compressor.

4. Evacuate the system using an approved recycling/recovery station.

NOTE:
WHEN REPLACING ANY COMPONENTS AND/OR OPENING ANY LINE FITTINGS, NEW R-134a COMPATIBLE SEALS OR 0-RINGS MUST BE INSTALLED.

5. Repair or replace any failed components with the exception of the compressor.
