NOTE: Gas dryers are equipped with a Direct Spark Ignition (DSI) system, which has internal
diagnostics. If ignition is not established after the first attempt, the heat circuit in the DSI
module will lockout until it is manually reset. To reset the DSI system, open and close the main
door and restart the dryer.
b. A 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 pressure tap of the gas valve body):
Natural Gas..........................3.5 Inches Water Column (8.7 mb).
Liquid Propane (L.P.) Gas ....10.5 Inches Water Column (26.1 mb).
IMPORTANT: There is no regulator provided in a L.P. dryer. The water column pressure must be
regulated at the source (L.P. tank), or an external regulator must be added to each
dryer.
4. Make a complete operational check of ALL safety related circuits:
a. Door Switch(es)
b. Hi-Limit Thermostats
c. Cycling Thermostats
d. Sail Switch (for Gas and Electric Models Only)
NOTE: The sail switch can be checked for proper operation by opening the lint door while the heating
circuit (gas burner/electric oven) is active (on). The heating unit should shutoff within a few
seconds. If not, make necessary adjustments to sail switch.
5. Make a complete operational check of ALL operating controls.
NOTE: If computer program changes are required, refer to the computer programming section of the
manual supplied with the dryer.
6. The dryer should be operated through one (1) complete cycle to assure that no further adjustments are
necessary and that ALL components are functioning properly.
BASKET COATING
The basket (tumbler) is treated with a protective coating. We suggest dampening old garments or cloth
material with a solution of water and nonflammable mild detergent and tumbling them in the basket (tumbler) to
remove this coating.
7. Check the electric service phase sequence (3-phase [3Ø] models Only). While the dryer is operating,
check to see if the blower wheel (impellor/fan) is rotating in the proper direction. Looking from the front,
the blower wheel (impellor/fan) should spin in the clockwise (CW) direction. If it is, the phasing is correct.
If the phasing is incorrect, reverse the two (2) leads at connections L1, L2, or L3 of the power supply to the
dryer.
