Total air reservoir capacity? _________________________
Charge time required to raise the reservoir
pressure from governor cut in to cut out
at rated engine speed? _________________________________
Recommended Test Procedure:
Drain down the entire air system (supply, service and accessory tanks) to below 75 psi. As
the compressor begins to charge the system, start a timer when the tank pressure reaches
the governor cut in pressure. Stop the timer when the compressor cuts out (dryer purge can
usually be heard)
Was measured charge time less than 90 seconds? YES
NO
Coolant Supply
Source: _________________________________________
Line size to: ____________________________________
Distance to: ____________________________________
Maximum allowable engine coolant temperature: ______________
Maximum expected compressor coolant temperature: ___________
Recommended Test Procedure:
Install a temperature probe in the coolant supply fitting on the compressor and
either monitor or measure the engine coolant temperature (at thermostat housing).
Operate the vehicle such that the engine reaches operating temperature. Record the
engine coolant temperature and the compressor coolant supply temperature. The
maximum expected compressor coolant temperature is the sum of the recorded
compressor coolant temperature and the difference between the recorded engine
coolant temperature and the maximum allowable engine coolant temperature.
Is the maximum expected compressor coolant supply temperature less than 220°F?
YES NO
