Fire Suppression System
G, H, K, S and U Models Only
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 19 mm (3/4 inch) hose. The fire suppression system
equipped tumble dryer must be supplied with a
minimum water pipe size of 12.7 mm (1/2 inch) and be
provided with a
minimum of 138 kPa (20 psi) and a
maximum of 827 kPa (120 psi) of pressure at all times.
Flowrate must be no less than, but approximately 57
liters (15 gallons) per minute.
NOTE: Water pressure under 138 kPa (20 pounds
per square inch) will cause low flow and water
leakage at water solenoid valve.
IMPORTANT: Temperature of the water supply
must be kept between 4.4° and 48.9°C (40° and
120°F). 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 4.4°C
(40°F), 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 4.4°C (40°F) 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
Figure 2
IMPORTANT: Thread hose couplings onto valve
connections finger tight, then turn 1/4 turn with
pliers. Do not cross thread or overtighten
couplings.
IMPORTANT: Replace all hoses every five years.
NOTE: Longer inlet hoses are available (as
optional equipment at extra cost) if the hoses
supplied with the tumble dryer are not long enough
for installation. Order hoses as follows:
Part No. 20617 Inlet hose 2.44 m (8 feet)
Part No. 20618 Inlet hose 3.05 m (10 feet)
Electrical Requirements
No independent external power source or supply
connection is necessary. Power to operate the 24 Volt
fire suppression system is from the rear junction/
contactor box.
