Fire Suppression System
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 is
adequate and conforms to local, state, and federal
regulations or codes.
IMPORTANT: It is the installation or owner’s
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.
Water Requirements
IMPORTANT: Water must be supplied to the fire
suppression 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 dryer 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, provisions 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 water 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 40°F
(4.4°C), the fire suppression system control will
lock out. This feature protects against operation of
the tumble dryer with a possible frozen water
supply. Only when the temperature sensors register
a temperature above 40°F (4.4°C) will the machine
reset for operation.
IMPORTANT: Flexible supply line/coupling must
be used. Solenoid valve failure due to hard
plumbing connections will void the warranty. It is
recommended that a filter or strainer be installed
in the water supply line.
Water Connections
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 5 and Figure 6.
Figure 5
To connect the two hoses (supplied with tumble
dryer), insert rubber washers (from literature pack) in
water inlet hose couplings. Refer to Figure 6.
