5. Electrically Heated Dryers
Check to ensure that electric oven/contactor assembly is activating.
6. Make a complete operational check of ALL safety related circuits:
a. Door Switch(es)
b. Hi-Limit Thermostats
c. Sail Switch (for Gas and Electric Models Only)
NOTE: To check for proper sail switch operation (for gas and electric 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.
7. The dryer should be operated through one (1) complete cycle to ensure 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.
8. Make a complete operational check of ALL operating controls.
For microprocessor model check 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.
9. 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, 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.
