PERFORMANCE TEST

1) Confirm that vehicle and environmental conditions are as fol-
2) Connect high and low side charging hoses of manifold gauge
3) Warm up engine to normal operating temperature and keep it
4) Turn A/C switch ON, and set blower switch at "HI", temperature

NOTE:
Pressure registered on gauge varies with ambient temper-
ature. Therefore, use left graphs when determining if pres-
sures are normal or not.
Example:
Gauges should read as follows when ambient temperature
is 30 C
