Functional Test

To aid in determining whether or not the air conditioning, electrical, air, and refrigeration systems are operating properly, refer to "Performance Test" in this section.

1. Operation of the air conditioning blower at all speeds, in any position except "OFF" and engagement of the compressor clutch indicates that the electrical circuits are functioning properly.

2. The same "handfelt" temperature of the evaporator inlet pipe and the accumulator surface of an operating system indicates a properly charged system.

3. Operation of the air conditioning control head to distribute air from the designed outlets indicates proper functioning.
