INSTALLATION

1.Requirements

The fire suppression system must be supplied with a minimum water pipe size of 1/2” and be provided with 40 psi +/- 20 psi (2.75 bar +/- 1.37 bar) of pressure. For use of optional manual bypass, a second source with the same piping and pressure requirements is required.

Flexible 1/2 feeds must be provided to avoid damage to electric water solenoid valve by vibration.

IMPORTANT: Flexible supply line/coupling must be used. Solenoid valve failure due to hard plumbing connections WILLVOID WARRANTY.

If the rear area of the 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.

WARNING: If the water in the supply line or water solenoid valve freezes, the fire suppression system will be INOPERATIVE!!

IMPORTANT: Appliance is to be connected to the water mains using a new hose set and the old hose set should not be reused.

2.Water Connections:

The water connection is made to the 3/4”-11.5 NH hose adaptor located at the rear upper midsection of the dryer (refer to the photograph).

The water solenoid valve has a 3/8” M.P.T. connection supplied with a 3/4”-11.5 NH hose adaptor to provide the minimum 1/2-inch supply (feed) line. Flexible supply line/coupling must be used in an effort to avoid damaging the electric water solenoid valve.

NOTE: The 3/4”-11.5 NH is a standard hose coupling screw thread. It is not to be confused with 3/4” N.P.T. The sealing of an NH connection is made with a washer opposed to the mating threads of an N.P.T. assembly. The two (2) thread designs are not compatible.

IMPORTANT: Flexible supply line/coupling must be used. Solenoid valve failure due to hard plumbing connections WILL VOID WARRANTY. It is recommended that a filter or strainer be installed in the water supply line.
