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 ensure 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 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 +/- 1.37 bar) 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-sets should not be reused.
2. Water Connections:
The water connection is made to the 3/4”-11.5 NH hose adapter
of the electric water solenoid valve, located at the rear upper
midsection of the dryer (refer to the photo).
The water solenoid valve has a 3/8” M.P.T. connection supplied with
a 3/4”-11.5 NH hose adapter 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.
NOTE: The 3/4”-11.5 NH is a standard hose coupling screw thread. It is not to be confused with
3/4” N.P.T. The sealing of an NH connection is made with a washer opposed to the mating
threads of an N.P.T. assembly. The two (2) thread designs are not compatible.
