3. Make a complete operational check of ALL safety related circuits:
a. Door Switch(es)
b. Hi-Limit Thermostats
c. Sail Switch - Gas Models
NOTE: To check for proper sail switch operation (for Gas Models), open the main door and while
holding main door switch plunger in, start dryer. The 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 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 and fan) is rotating in the proper direction. Looking from the front, the
blower wheel (impellor and 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 and fan) is rotating in the wrong direction, this will not
only drastically reduce drying efficiency, but it can also cause premature component
failure.
