28 American Dryer Corp. 113231-4
Provisions are made in the dryer fire suppression system for the installation of an optional manual bypass.
Depending on the model dryer, the connections for the manual bypass are made at the “T” or “three way” fitting
located in the outlet supply side of the water solenoid valve. The manual ball cock shutoff valve must be located
outside of the dryer at a distance from the dryer where it is easily accessible. The use and connections of this
manual bypass are at the option or discretion of the owner.
The water connection for the manual bypass is made to the “T” or “three way” fitting, which has a 3/8” F.P.T.
and a coupling must be used to provide the minimum 1/2” supply (feed) line.
If the rear area of the dryer or the water supply is located in an area where it
will be exposed to cold/freezing
temperatures, provisions must be made to protect these water lines from freezing.
Optional Manual Bypass
3. Electrical Requirements:
No independent external power source or supply connection is necessary. The 24-volt power to operate
the fire suppression system is accomplished internally in the dryer (from the dryer controls).
WARNING: Electrical power must be provided to the dryer at ALL times. If the main electrical
power supply to the dryer is disconnected, the fire suppression system is
INOPERATIVE!!
