Fire Suppression System
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 tumbler 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 liter
(15 gallons) per minute.
NOTE: Water pressure under 138 kPa (20 psi) 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
tumbler register a temperature below 4.4°C (40°F),
the fire suppression system control will lock out.
This feature protects against operation of the
tumbler 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 tumbler 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.
Auxiliary Alarm
During tumbler installation, you have the option to
connect a separate alarm system to this auxiliary
output. Use of the auxiliary output is not required for
the fire suppression system to operate, but may be used
for additional protection.
NOTE: The auxiliary output is activated during
fire suppression system maintenance test sequence.
Consider this fact prior to your system test every
three months. (Example: If the external system uses
the auxiliary output to call the fire department,
inform the fire department before and after the fire
suppression system maintenance test.)

Electrical power must be provided to
tumbler at all times. The fire suppression
system will be inoperative if the main
electrical power supply is disconnected.
