As an aid in determining whether or not the air conditioning, electrical, air, and refrigeration systems are operating properly use the System Performance Table.

1. The operation of the air conditioning blower at all speeds, in any position except the OFF position, and the engagement of the compressor clutch indicate that the electrical circuits are functioning properly.
2. The same hand-felt temperature of the evaporator inlet pipe and the accumulator surface of an operating system indicates a properly charged system.
3. The operation of the air conditioning control head in the distribution of air from the designated outlets indicates proper functioning.
