Single and Multiple Shower System Applications
Technical Instructions
Description
The ESP (Electronic Sensor Plumbing) Hydropanel™ II Pushbutton Shower
System combines modular shrouding with the convenience of electronic
water control. Hydropanel™ II shrouding provides a concealed shower
system where in-wall piping does not exist or may not be practical. The ESP
Pushbutton Shower System relies on Piezo sensor technology to deliver
tempered water to a shower for a predetermined length of time. The shower
automatically turns on when a bather presses the pushbutton, and automatically shuts off when a bather presses the pushbutton again, or when
the field adjustable run-time has been reached.
Multiple shower applications can utilize the ESP Group Control Box, which
centralizes ESP control for up to eight showers. A microprocessor in the
Group Control Box allows the shower system to be custom programmed for
maximum run time, remote override capability.
The Powers Series 450-ESP shower systems come complete with stainless
steel Hydropanel™ II shrouding, ESP Pushbutton Shower System, showerhead, piping, soapdish and mounting hardware.
The following instructions serve as a guide for installation of the Powers
ESP Hydropanel™ II Pushbutton Sensor shower systems. Powers recommends good safety practices and care when installing electrical equipment.
Please follow the procedures as outlined. For additional assistance, please
call the Powers Application Engineering Department at 1.800.669.5430.

Precautions Before Installation:
• Use a 24V AC step-down transformer.
• Do not supply power to, or plug in, the transformer until all
other wiring is complete. To prevent permanent damage to
the transformer, do not allow power transformer wires to
touch during wiring.
• Before connecting the solenoid valve, flush Hydropanel™
supply lines to ensure supply water will be free of grit, sand,
etc. The solenoid valve requires water free of all foreign matter to operate properly.
• To inhibit corrosion, a waterproof, multi-purpose grease may
be sprayed onto all electrical contacts.
• Follow the national/local codes and regulations for all
electrical wiring and plumbing.
• Use stainless steel screws for all component installations.
Tools Required:
• Slotted and Phillips screwdrivers.
• Drill with 5/8" bit.
• Pipe wrenches.
• Pipe dope/sealing compound.
• Allen Wrench(s) (included with shrouding).
The ESP Hydropanel™ II Shower System includes a
solenoid valve (non-metallic or brass) which receives tempered water though pre-installed piping. A Powers master
mixing valve such as the 430 Thermostatic mixing valve, or
Hi-Lo cabinet supply fixture, can be used to safely supply comfortable water to the ESP Hydropanel™ shower system.

Front and Side Views - Dimensions of the ESP Hydropanel™ II Pushbutton Shower
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 distance
between the centerline of two units is 36 inches.
Determine the floor-to-showerhead height for the unit.
Recommended 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.
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 showerhead remains part of the shroud.
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.

FLOOR LINE
The non-metallic solenoid has 3/4" NPT end connections, and a
straight through flow path to minimize pressure loss. Make sure
the manual override switch is in the "OFF" position, or else water
will flow regardless of sensor activity.
End Cap

B B'
The brass solenoid has 1/2" NPT end
connections.
Connect the supply line to the solenoid. Use 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 Control Box
The control box (Figure 5), with standard cables, can be positioned up to 4 feet from the pushbutton/proximity sensor assembly and up to 2 feet from the solenoid valve. [Optional cable
extensions can extend these distances to 1000 feet from the
sensor assembly, 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.
