ADC AD-78 - Manual (Page 41)

c. Electric Models
1) Check to insure that electric oven/contactor assembly is activating.
3. Make a complete operational check of ALL safety related circuits:
a. Door Switch(es)
b. Hi-Limit Thermostats
c. Sail Switch (for Gas Models and Electric Models ONLY)
NOTE; To check for proper sail switch operation (for Gas Models and Electric Models ONLY),
open the main door and while holding main door switch plunger in, start the 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 to 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.
IMPORTANT: The dryer basket (tumbler) is treated with a protective coating. ADC suggests
tumbling old clothes or material in the basket (tumbler), using a mild detergent
to remove the protective coating.
5. Make a complete operational check of ALL operating controls.
a. For microprocessor models check controller (computer) 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 [30] models only). While the dryer is operating, check
to see if the blower wheel (impeller/fan) is rotating in the proper direction. Looking from the front, the
blower wheel (impeller/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 LI, 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.______________________________________________________
