Normal System Performance - Service Stall

Normal System Performance Service Stall:

IMPORTANT:
^ To ensure accurate pressure and temperature readings make sure the vehicle is properly set up to run the performance test. (Refer to vehicle set up.) All test parameters must be followed to obtain accurate readings. Confirm system performance by touching the suction and discharge pipes at the compressor. The suction pipe will he cold and the discharge pipe will he hot.
^ Use a refrigerant identifier to verify refrigerant purity. Non-condensable gases or refrigerant substitutes will affect system pressure/temperature readings.
