Fire Suppression System (Optional
Equipment)
WARNING
Electrical shock can result in death or serious injury.
If the water dispensing system is activated, do not
attempt to operate the tumble dryer. If the water dis-
pensing system is activated, have the tumble dryer
inspected by a qualified agency before operating the
tumble dryer.

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 professio-
nal to assure that the plumbing is adequate and con-
forms to local, state, and federal regulations or codes.
IMPORTANT: It is the installation or owner’s responsi-
bility to see that the necessary or required water, water
pressure, pipe size, or connections are provided. Man-
ufacturer assumes no responsibility if the fire suppres-
sion system is not connected, installed, or maintained
properly.
Water Requirements
IMPORTANT: Water must be supplied to the fire sup-
pression system, or the fire suppression system will
not operate as intended.
Connection point to the electric water solenoid valve is a 3/4 inch
[19 mm] hose. The fire suppression system equipped tumble dry-
er must be supplied with a minimum water pipe size of 1/2 inch
[12.7 mm] and be provided with a minimum of 20 psi [138 kPa]
and a maximum of 120 psi [827 kPa] of pressure at all times.
Flowrate must be no less than, but approximately 15 gallons [57
liters] per minute.
NOTE: Water pressure under 20 psi [138 kPa] will
cause low flow and water leakage at water solenoid
valve.
If the rear of the tumble dryer or the water supply is located in an
area where it will be exposed to cold/freezing temperatures, pro-
visions must be made to protect these water lines from freezing.
IMPORTANT: Temperature of the water supply must be
kept between 40°F and 120°F [4.4°C and 48.9°C] . If wa-
ter in the supply line or water solenoid valve freezes,
the fire suppression system will not operate.
IMPORTANT: If temperature sensors inside the tumble
dryer register a temperature below 40F° [4.4°C] , the
fire suppression system control will lock out. This fea-
ture protects against operation of the tumble dryer with
a possible frozen water supply. Only when the temper-
ature sensors register a temperature above 40F°
[4.4°C] will the machine reset for operation.
IMPORTANT: Flexible supply line/coupling must be
used. Solenoid valve failure due to hard plumbing con-
nections will void the warranty. It is recommended that
a filter or strainer be installed in the water supply line.
Water Connections
Connect machine to a backflow preventer (vacuum breaker) be-
fore connecting to the public water main in all countries where
local regulations require specific water approval certificates.
Two hoses and a Y-valve are provided with the tumble dryer to
allow for connection of water supply to tumble dryer. The water
connections are made to the bushings of the water solenoid valve,
located on the rear of the tumble dryer. The Y-valve provides a
single female hose connection (Standard US 3/4-11 1/2 NH
thread). Refer to
Figure 4
and
