3. PLUMBING HOOK-UP
A. Water Input (Diagrams 2 & 3, see last page)
The primary solenoid should be connected to a hot water source.
This solenoid has a ½” NPT female opening. A ½”MNPT x 3/4”MGH
adapter has been supplied for hot water hookup using a standard
washing machine water supply hose (not supplied). It is recommended
that a filter washer be installed into the water supply hose to prevent
sediment debris from entering solenoid from water source. The high-
pressure hose should connect the solenoid to a shut-off valve (not
supplied) at you water source. A flow regulator is incorporated into the
unit; therefore, the shut-off valve must not restrict the flow more than
3.5 GPM.
Also, a backflow regulator (not supplied) may have to be attached at your
water source to comply with local regulations.
B. Water Output (Diagram 2, see last page)
1½” x 16” elbow (A), which is supplied, is to be attached with a slip nut
(B) and washer (C) to the 1½” output nipple. (This piece can be hooked
up prior to installation of the tank but that is not necessary. The
tailpiece (D) with ¾” input (supplied) is to be attached to elbow (A) with a
slip nut (E) and adapting washer (F). Attached to the tailpiece, with
a hose clamp (G), will be 2’ of ¾” hose (I). The other end of this hose is to
be attached to be attached to hose adapter (H), with the hose clamp (G),
after (H) is threaded into the drain solenoid using Teflon tape or joint
compound. A “P” trap (not supplied) is then to be attached to tailpiece
(D) prior to hookup to drain line.
4. ELECTRICAL
The unit is rated at 1500 W, 120 VAC, 50/60 HZ. Only the power module is
plugged into your 120VAC supply (diagram).
The Tank Module has two plugs. Both plugs are attached to power module at
receptacles C & E.
Control Module plug (M) plugs into power module receptacle (G).
Only the plug from power module (A) is to be connected to your power source.
Unit must be electrically grounded. The power cord must be connected to a
three-way grounded outlet. For 2-wire service, an adapter with external ground
wire is necessary. Connect the green grounding wire of the adapter to the
