Troubleshooting
Whenever abnormal high or low side pressures are noted, diagnosis must be conducted by using a manifold gauge set. The following table refers to the normal pressure range for the high or low side. Since the normal pressure differs from area to area, refer to the "ambient Temperature-Pressure Chart".
Note:
Pressure measurements are effective only when ambient temperature is in the range indicated under the beading "Performance" topic
