1. Installation
a. 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 set
should not be
reused.
b. 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 photo).
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.
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.
