Water Connections:

The water connection is made to the 1” F.P.T. bushing of the electric water solenoid valve located at the

front lower left area of the dryer. The water solenoid valve has a 1/2” M.P.T. connection and a 1/2”

bushing is supplied to provide the minimum 1/2-inch supply (feed) line. Flexible supply line/coupling must

be used in effort to avoid damage to electric water solenoid valve.

WARNING: Water must be supplied to suppression system or dryer will not operate.

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.
