ADC AD-120ES Installation Manual page 24

Optional Manual Bypass
Provisions are made in the dryer's 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 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.
24
If the water in the supply line or water solenoid valve
freezes, the fire suppression system will be
inoperative!!
The manual ball cock shutoff valve must be located outside
of the dryer at a distance from the dryer where it is easily
accessible.
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).
