American Dryer Corp MD-170 manual Shut Down Instructions, Basket Coating

Page 40

7.A reversing tumbler (basket) dryer should never be operated with less than a 60 lb. (27 kg) load (dry weight). The size of the load will affect the coast-down and dwell (stop) times. The tumbler (basket) must come to a complete stop before starting in opposite direction. For microprocessor controller (computer) models, with the automatic (mode) cycle only, the Spin Time and Stop Time are not adjustable. The spin times and stop times have been preprogrammed into the microprocessor controller (computer) for 120-seconds spin time and a 5-second dwell (stop) time. (For timer controlled models, refer to the Reversing Timer Spin/Dwell Adjustments in Section VIII of this manual.)

BASKET COATING

The tumbler (basket) is treated with a protective coating. We suggest dampening old garments or cloth material with a solution of water and non-flammable mild detergent and tumbling them in the tumbler (basket) to remove this coating.

8.Each dryer should be operated through one (1) complete cycle to assure that no further adjustments are necessary and that ALL components are functioning properly.

9.Programs/selections (for microprocessor [computer] models Only):

a.Each 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.

K. SHUT DOWN INSTRUCTIONS

If the dryer is to be shut down (taken out of service) for a period of time, the following must be performed:

1.Discontinue electrical power to the dryer either at the external disconnect switch or the circuit breaker.

2.Discontinue the heat supply:

a.GAS MODELS ... discontinue the gas supply.

1)SHUT OFF external gas supply shut-off valve.

2)SHUT OFF internal gas supply shut-off valve located in the gas valve burner area.

b.STEAM MODELS ... discontinue the steam supply.

1)SHUT OFF external (location furnished) shut-off valve.

2)SHUT OFF internal steam valves in the supply lines and the return lines.
