Powers 450 Infrared ESP HydroPanel II Infrared Sensor System - Manual (Page 2)

WARNING: Before installing solenoid, flush the pipes to
ensure supply water is free of grit and sand.
NOTE:
A service stop can be installed directly upstream of the
solenoid to facilitate maintenance and repair.
The brass solenoid has 1/2" NPT end connections.
Connect the supply line to the solenoid, using only thread
sealant on male threads. Do not use Teflon tape; it will clog
the solenoid valve. Connect the inlet piping so water flows in
the direction of the arrow on the solenoid. To mount the upper
bracket of the piping assembly, drill the holes at the same
height as the top of the showerhead (B and B’) .
Install Modular Junction Box
The Modular Junction Box (MJB) with standard cables, can
be positioned up to 2 feet from the infrared sensor and up to
2 feet from the solenoid valve. [Optional cable extensions can
extend these distances to 1000 feet from the infrared sensor,
and 300 feet from the solenoid valve.] Remove the cover. Use
the box as a template to mark positions on the wall for two
mounting screws. Drill holes and attach the box.
Connect one of the power supply wires (supplied with ESP kit)
to the terminals. Tighten the screws for a secure connection.
Replace the cover.
Install the Transformer
The plug-in and box mount transformers can be positioned
in a chaseway, closet or ceiling. Each can power up to eight
solenoids. For shower system maintenance, a remote shut-off
switch can be installed.
WARNING: Do not supply power to or plug in the transformer
until all wiring is complete.
• Box Mount Transformer
The box mount transformer will mount on a 110V AC sup-
ply electrical junction box. The “J” box should be inside the
chase wall or above the ceiling. Connect the power supply
wires from the MJB to the secondary side of the transformer
(Figure 5). Tighten the screws.
Position the ESP Hydropanel II Unit
Determine the horizontal position of the unit according to
shower room layout, and mark the centerline (Figure 3). For
multiple shower applications, the recommended minimum dis-
tance between the centerline of two units is 36 inches.
Determine the floor-to-showerhead height for the unit.
Recommended shower head heights are listed below:
Men 77" [1955.8mm] - Youth 66" [1676.4mm]
Women 70" [1778mm] - Youth 60" [1524mm]
Determine where the inlet piping will connect to the solenoid.
For the non-metallic solenoid, this connection is typically
1-1/2" below showerhead height,
and 2-1/4" left of centerline. For a
brass solenoid, it is 2-1/2" below
showerhead height, and 2-1/4" left
of centerline (refer to Figure 3).
Install the Solenoid and
Piping Assembly
The piping and Hydropanel II
shrouding come pre-assembled
(Figure 4). To detach, remove the
screws at the showerhead (A) and
bottom bracket (C and C’). Slide the
piping out of shrouding; the show-
erhead remains part of the shroud.
