BEFORE YOU START!
CHECK LOCAL CODES AND PERMITS
Call your local water company or the proper municipal authority for information regarding local codes.
IMPORTANT: It is your responsibility to have ALL plumbing connections made by a qualified
professional to assure that the plumbing installation is adequate and conforms to local,
state, and federal regulations or codes.
IMPORTANT: It is the installation or owners responsibility to see that the necessary or required
water, water pressure, pipe size, or connections are provided. Manufacturer assumes
no responsibility if the fire suppression system (F.S.S.) is not connected, installed, or
maintained properly.
INSTALLATION
1. Requirements
The connection point to the electric water solenoid valve is a 1/2” M.P.T., the FSS MUST BE supplied
with a minimum water pipe size of 1/2-inch and be provided with 40 PSI +/- 20 PSI (2.75 bars +/- 1.37
bars) of pressure. For use of optional manual bypass, a second source with the same piping and pressure
requirements is required.
Flexible 1/2 feeds must be provided to avoid damage to electric water solenoid valve by vibration.
IMPORTANT: Flexible supply line/coupling MUST BE used. Solenoid valve failure due to hard
plumbing connections WILL void warranty.
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.
WARNING: If the water in the supply line or water solenoid valve freezes, the F.S.S. will be
INOPERATIVE!!
