INSTALLATION PROCEDURES
J. PRE-OPERATIONAL TESTS
All dryers are thoroughly tested and inspected before leaving the factory. However, a
preoperational test should be performed before the dryer is publicly used. It is possible that
adjustments have changed in transit or due to marginal location (installation) conditions.
1. Turn on electric power to the dryer.
2. Refer to the Operating Instructions for starting your particular model dryer.
3. GAS DRYERS:
a. When a gas dryer is first started (during initial startup), it has a tendency not to ignite on
the first ignition attempt. This is because the gas supply piping is filled with air, so it may
take a few minutes for the air to be purged from the lines.
NOTE: Gas dryers are equipped with a Direct Spark Ignition (DSI) system which has internal
diagnostics. If ignition is not established after three (3) attempts, the heat circuit in the DSI
module will lock out 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 pressure is correct and consistent.
NOTE: Water column pressure requirements (measured at the pressure tap on the gas valve body)
Natural Gas..... 4 Inches Water Column
L.P. Gas......... 11 Inches 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:
a. Door switch
b. Hi – limit thermostats
c. Cycling thermostats
d. Sail switch (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 shut off
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.
IMPORTANT: The dryer basket is (tumbler) treated with a protective coating. Dryer suggests
