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 photograph).
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.
Important
Flexible supply line/coupling must be used.
Solenoid valve failure due to hard plumbing
connections will void warranty. It is recommended that a
filter or strainer be installed in the water supply line.

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.
It is the installation 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 ___________________________
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.
