American Dryer Corp ADH-170 Preoperational Instructions, Non-Coin Models, Shutdown Instructions

Microprocessor Models – Spin and dwell (stop) times are adjustable in the Manual (timed) Mode. Spin and dwell (stop) times are not adjustable in the Automatic Mode and have been preprogrammed into the microprocessor controller (computer) for 150-seconds spin time in forward direction, 120-seconds in the reverse direction and a 5-second dwell (stop) time.

Mechanical Timer Models – Timer models have an electronic reversing timer in the electrical service box, which is located in the upper right front area of the dryer.

Both the dwell (stop) time and the tumbler spin time are adjustable by mode selection switches located on the electronic timer (as noted in the illustration below).

Preoperational Instructions __________

Important

! For more detailed information regarding the microprocessor controller (computer), refer to the

microprocessor user’s manual included with the dryer.

Non-Coin Models

Microprocessor Controller (Computer)

The L.E.D. display reads “READY” (no cycle in progress).

Press the letter on the keypad corresponding to the cycle desired (i.e., key “D”).

The dryer will then start (i.e., blower, tumbler, and heat).

The L.E.D. display will read MANUAL DRYING CYCLE D, 00:00

MIN REMAIN.

Note

!The dryer can be stopped at any time by pressing the “STOP/CLEAR” key, at this time the dryer will

go into a cycle pause. If the “STOP/CLEAR” key is pressed again at this point, the cycle that was in progress will be cancelled and returned to the “READY” state.

When the programmed drying time has expired, the Phase 7 non-coin microprocessor controller (computer) will proceed into the Cool Down Cycle.

Once the Cool Down Cycle begins at the end of the heat cycle, the L.E.D. display will read COOL DOWN TEMP ___/

___ MINUTES remaining. At the end of the heat cycle, the dryer will shut off the heat and continue the fan and tumbler until the Cool Down Time or temperature is reached.

Mechanical Timer

Turn drying timer knob for a time of 20 minutes. Select “High Temp.”

Push “Push to Start” button.

To stop the dryer, open the main door.

Shutdown Instructions ________________

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

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

Discontinue the heat supply:

Steam Models – Discontinue the steam supply. SHUT OFF external (location furnished) shutoff valve.

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