48 American Dryer Corp. 113406-1
FIRE SUPPRESSION 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.
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 fire suppression
system valve check at every 4000 hours to ensure proper functionality. At the 4000 hour mark, the microprocessor
controller (computer) 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 microprocessor controller (computer) will activate the fire
suppression system water valve for 2-seconds, at which point the microprocessor controller (computer) will
prompt the user with the following message, “IF WATER DID NOT TURN ON, CALL FOR SERVICE.
THANK YOU.”
NOTE: The microprocessor controller (computer) will not let the user continue until the valve test has
been completed.
FIRE SUPPRESSION SYSTEM DIAGNOSTICS
In the event that the Phase 7 non-coin microprocessor controller (computer) detects a fault in the fire suppression
system the microprocessor controller (computer) will display the message “F.S.S. DISABLED…READY.” To
find out why the fire suppression system is disabling, press and hold the red “STOP/CLEAR” and green “START”
keys. This will cause the microprocessor controller (computer) to display a diagnostic message, as detailed in
the “Fire Suppression System Diagnostics Messages” section.
