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.
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.
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.
7. Make a complete operational check of ALL operating controls.
Microprocessor controller (computer) programs/selections.
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.
8. 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 it will drastically
reduce drying efficiency and it can also cause premature component failure.
9. Reversing basket (tumbler) dryers should never be operated with less than a 53 lb (24.04 kg) load (dry
weight), since the load’s weight affects basket (tumbler) coast time during a direction reversal command.
It is important that the basket (tumbler) come to a complete stop prior to starting in opposite direction.
a. Spin and dwell (stop) times are not adjustable in the Automatic Mode and have been preprogrammed
into the microprocessor controller (computer) for a 120-second spin time in forward direction,
120-seconds in the reverse direction and a 5-second dwell (stop) time.
b. Spin and dwell (stop) times are adjustable in the Manual (timed) Mode.
10. Check to ensure that ALL setscrews (i.e., basket [tumbler] drive, idler, etc.) are tight.
