I. WATER INFORMATION
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 installer’s or owner’s responsibility to see that the necessary or required
water, water pressure, pipe size, or connections are provided. The manufacturer assumes no
responsibility if the fire suppression system
is not connected, installed, or maintained properly.
INSTALLATION
1. Requirements
The fire suppression system must be supplied with a minimum water pipe size of 1/2” and be provided with
40 psi +/- 20 psi (2.75 bar, 275 kPa +/- 1.37 bar, 137 kPa) 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 fire suppression
system will be INOPERATIVE!!
IMPORTANT: Appliance is to be connected to the water mains using a new hose set and the old
hose set should not be reused.
2. Water Connections:
The water connection is made to the 3/4”-11.5
NH hose adaptor of the electric water solenoid
valve, located at the rear upper midsection of the
dryer (refer to the photograph).
The water solenoid valve has a 3/8” M.P.T.
connection supplied with a 3/4”-11.5 NH hose
adaptor to provide the minimum 1/2-inch supply
(feed) line. Flexible supply line/coupling must
be used in an effort to avoid damaging the electric
water solenoid valve.
