Test

Procedure:

Install a temperature probe at the air dryer inlet fitting. Operate the vehicle such
that the engine is at operating temperature. Drain an air tank such that the
compressor runs continuously but the pressure remains about 10 psi below the
governor cutout pressure. Note the dryer air inlet temperature after the compressor
has run for 90 seconds. Also note the ambient temperature. To obtain the
maximum air inlet temperature, add the difference between the recorded inlet
temperature and the noted ambient temperature to the maximum expected ambient
temperature. Likewise, to obtain the minimum expected inlet temperature, add the
temperature difference to the minimum expected ambient temperature.
