American Dryer Corp. AD-540 Clothes Dryer User Manual


 
24
The dryer is equipped with a direct spark ignition (DSI) system which has internal diagnostics. If ignition
is not established the heat circuit DSI module will lockout until it is manually reset. To reset the DSI
system, open and close main door and restart dryer (press desired temperature selection).
NOTE: During the purging period, check to be sure that ALL gas shut-off valves are open.
b. Once ignition is established, a gas pressure test should be taken at the gas valve pressure tap of each
dryer to assure that the water column pressure is correct and consistent.
NOTE: Water column pressure requirements (measured at the gas valve pressure tap):
Natural Gas ---- 3.5 Inches Water Column (8.7 millibars)
L.P. Gas-------- 10.5 Inches Water Column (26.1 millibars)
IMPORTANT: THERE IS NO REGULATOR PROVIDED IN AN 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 (i.e., lint basket switches and sail switches).
5. Each tumbler (basket) should be operated through one (1) complete cycle to assure that no further
adjustments are necessary and that ALL components are functioning properly.
NOTE: The sail switch can be checked for proper operation by opening the control door while the
dryer is running and the heating unit (burner) active (on). The heating unit(s) should shut-off
within a few seconds. If not, make the necessary adjustments.
BASKET COATING
The tumbler (basket) is treated with a protective coating. We suggest dampening old garments or cloth
material with a solution of water and non-flammable mild detergent and tumbling them in the tumbler (basket)
to remove this coating.
NOTE: Drying and cooling cycles are complete when the L.E.D. (light emitting diode) display reads ...
“donE.”
6. Computer Programs/Selections...
Each Microprocessor Controller computer has been preprogrammed by the factory with the most commonly
used program (parameter) selections. If microprocessor (computer) program changes are required, refer
to the Microprocessor Controller Programming Manual which was shipped with the dryer.
