NOTE: To check for proper sail switch operation, 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.
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.
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. Check the electric service phase sequence (3-phase [3ø] models only). While the dryer is operating, check
to see if the blower (impellor/fan) wheel is rotating in the proper direction. Looking from the front, the
blower (impellor/fan) wheel 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 (impellor/fan) wheel is rotating in the wrong direction, this will not only
drastically reduce drying efficiency, but it can also cause premature component failure.
