System Performance Test

This test is performed to establish the condition of all components in the system. Observe these conditions during testing: 1. Start engine and operate at 1200 to 1500 RPM.
2. Place fan in front of condenser to simulate normal ram air flow and allow system to stabilize.
3. Place a thermometer in air conditioning vent closest to evaporator.
4. Evaluate the readings obtained from the gauges to see if they match the readings for the ambient temperature.
5. As preliminary steps to begin checkout of the system, perform the following: A. Close all windows and doors to the cab.
B. Set air conditioning system at maximum cooling and blower speed operation.
C. Readings on the two manifold gauges should be within normal range, adjust for ambient temperature.
D. Compare evaporator discharge air temperature reading to see if it matches the recommended temperature for the ambient temperature and gauge readings obtained.
E. Carefully feel the hoses and components on the high side. All should be warm-hot to the touch. Check the inlet and outlet of receiver-drier for even temperatures, if outlet is cooler than inlet, a restriction is indicated.
