C. OPERATIONAL SERVICE CHECK PROCEDURE

After performing any service or maintenance function, an operational check should be performed to ensure that ALL components are performing properly.

1.Make a complete operational check of ALL the operating controls to assure that the timing is correct, temperature selection switches are functioning, etc.

2.Make a complete operational check of ALL safety related circuits, door switch(es), hi-limit thermostat, sail switch, cycling thermostats, etc.

3.On gas models, gas pressure test should be taken at the gas valve pressure tap of each dryer to assure that the water column (W.C.) pressure is correct and consistent.

NOTE: Water column pressure requirements (measured at the gas valve pressure tap):

Natural Gas _________________ 3.5 inches (8.7 mb) water column.

Liquid Propane (L.P.) Gas ______ 10.5 inches (26.1 mb) water column.

4.The dryer should be operated through one (1) complete cycle to assure that no future adjustments are necessary and that ALL components are functioning properly.

5.For 3-phase (3ø) motor models, check the electric service phase sequence while the dryer is operating. Check to see if the blower wheel is rotating in the proper direction. Looking from the front, the blower wheel should spin in the clockwise direction. If so, the phasing is correct. If the phasing is incorrect, reverse two (2) leads at connections L1, L2, L3 of power supply to the dryer.
