American Dryer Corp AD-24 Phase 7 S.A.F.E. System Water Valve Check, S.A.F.E. SYSTEM Diagnostics

S.A.F.E. SYSTEM WATER VALVE CHECK

The operation of the water solenoid valve can be tested to ensure that the water supply system and valve are functional. Before attempting a system check, be sure that ALL water supply shutoff valves to the dryer are in the OPEN position; the dryer must be in the “READY” mode with no cycle loaded or in progress.

NON-COIN

1.Press and hold the red “STOP/CLEAR” key (while in “READY” mode and no cycle is in progress).

2.Press and hold the “A” key.

3.Water valve will open and water will be dispensed into basket (tumbler) area as long as both keys are held.

The Phase 7 non-coin microprocessor controller (computer) will prompt the user to perform a S.A.F.E. system valve check at every 4000 hours to ensure proper functionality. At the 4000 hour mark, the control will wait for end of the cycle and then will prompt the user to “PLEASE EMPTY TUMBLER, THEN PRESS THE ‘STOP/CLEAR’ AND ‘A’ KEYS TO TEST THE WATER VALVE.” When the ‘STOP/CLEAR’ and ‘A’ keys are pressed, the control will activate the S.A.F.E. system water valve for 2-seconds, at which point the control will prompt the user with the following message: “IF WATER DID NOT TURN ON, CALL FOR SERVICE. THANK YOU.”

NOTE: The control will not let the user continue until the valve test has been completed.
