2. Water Connections:

The water connection is made to the 3/4-11.5 NH

hose adapter of the electric water solenoid valve,

located at the rear upper midsection of the dryer (refer

to the photo).

The water solenoid valve has a 3/8 M.P.T. connection

supplied with a 3/4-11.5 NH hose adapter 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

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.

Typical water supply:
