b. Once ignition is established, a gas pressure test should be taken at the gas valve pressure tap of each
dryer to ensure 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.
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 basket (tumbler) should be operated through one (1) complete cycle to ensure 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 (TUMBLER) 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.
NOTE: When the drying and cooling cycles are complete, the light emitting diode (L.E.D.) 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 controller (computer) program changes are required
refer to the Microprocessor Controller Programming Manual, which was shipped with the dryer.
J. SHUTDOWN INSTRUCTIONS
In the case where the dryer is to be shutdown (taken out of service) for a period of time, the following must be
performed:
1. Discontinue power to the dryer (both baskets [tumblers]) either at the external disconnect switch or the
circuit breaker.
2. Discontinue the gas supply:
SHUT OFF external gas supply shutoff valve.
