9. Rotate the basket (tumbler/drum) by hand to be sure it moves freely.
10. Check bolts, nuts, screws, terminals, and fittings for security.
11. STEAM MODELS - check to insure air supply (80 PSI [5.51 bars]) is connected to the dryer.
12. STEAM MODELS - check to insure
ALL
steam shutoff valves are open.
13. STEAM MODELS - check steam damper operation.
14. Check basket (tumbler) bearing setscrews to insure they are
ALL
tight.
K. PREOPERATIONAL 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. Make sure the main door is closed and the lint drawer is securely in place.
3. Refer to the Operating Instructions for starting your particular model dryer.
4. Check to insure that the basket (tumbler) starts in the clockwise (CW) direction. Additionally, check the
direction of the blower motor impellor (fan) to insure that the impellor (fan) rotates in the clockwise (CW)
direction as viewed from the front. If it is, the phasing is correct. If the phasing is incorrect, reverse two
(2) of the leads at L1, L2, or L3 of the power supply connections made to the dryer.
IMPORTANT:
Dryer blower motor impellor/fan as viewed from the front must turn in the clockwise
(CW) direction, otherwise the dryer efficiency
will
be
drastically reduced and
premature component failure can result.
5. Heat Circuit Operational Test
a. Gas Models
1) When the dryer is first started (during initial start-up), the burner has a tendency not to ignite on the
first attempt. This is because the gas supply piping is filled with air, so it may take a few minutes for
this air to be purged from the lines.
2) The dryer is equipped with a Direct Spark Ignition system, which has internal diagnostics. If
ignition is not established after the first attempt, the computer will go into retry mode. If ignition is
not established after two (2) retries, no heat condition occurs.
