NOTE: To check for proper sail switch operation (for gas models only), open the main door and while
holding main door switch plunger in, start dryer. Dryer should start but heat circuit should not
be activated (on). If the heat system is activated, the sail switch is improperly adjusted and
must be adjusted by bending the actuator arm of the sail switch toward the burner box. If the
actuator arm is bent too far toward the burner box of the dryer, the dryer may not have heat
when needed. After any adjustment to the sail switch, the above procedure must be repeated
to verify proper operation of the sail switch.
4. 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 (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.
5. Make a complete operational check of
ALL operating controls.
a. For microprocessor controller (computer) model check programs/selections...
1) Each microprocessor controller (computer) has been preprogrammed by the factory with the most
commonly used parameter (program) selections. If computer program changes are required, refer
to the computer programming manual, which was shipped with the dryer.
6. 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 two (2) of the three (3) leads at connections L1, L2, and L3 of the power
supply to the dryer.
IMPORTANT: If the blower wheel (impellor/fan) is rotating in the wrong direction, this will not only
drastically reduce drying efficiency, but it can also cause premature component failure.
7. Reversing Models Only - basket (tumbler) dryer should never be operated with less than a 50 lb (22 kg)
load (dry weight). The size of the load will affect the coast-down and dwell (stop) times. The basket
(tumbler) must come to a complete stop before starting in opposite direction.
a. Microprocessor Models
1) Spin times and stop (dwell) times are not adjustable in the Automatic Mode and have been
preprogrammed into the microprocessor controller (computer) for 120-seconds spin time and a 5-
second dwell (stop) time.
2) Spin times and stop (dwell) times are adjustable in the Manual (timed) Mode.
b. Dual Timer Models
1) Both dwell (stop) time and basket (tumbler) spin time are adjustable (refer to the illustration on
page 37).
8. Check to insure that ALL setscrews (i.e., basket [tumbler] drive, idler, etc.) are tight.
