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 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 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 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.

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)
