Powers 450 Piezo ESP HydroPanel II Sensor System for Single and Multiple Shower System Applications User Manual

Installation cont.

Push the two power supply wires (supplied with ESP kit)

through the hole in the side of the Control Box. Insert one wire

into each power connector and tighten each screw 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 ceil-

ing. Each can power up to eight

solenoids. For shower system

maintenance, a remote shutoff

switch can be installed.
WARNING: Do not supply

power to or plug in the trans-

former until all wiring is com-

plete.

Plug-In Transformer
The plug-in transformer will connect to a

110V AC wall outlet. Connect the two power

cord wires from the Control Box (or GCB) to

the screw terminals on the secondary side

of the transformer (Figure 6). Tighten the

screws.
NOTE: The wires can be lengthened with 22

gauge bell wire.
Box Mount Transformer

The box mount transformer will mount

on a 110V AC supply electrical junc-

tion box. The "J" box should be inside

the chase wall or above the ceiling.

Connect the power supply wires from

the Control Box (or GCB) to the sec-

ondary side of the transformer (Figure

7). Tighten the screws.

ESP System Test
Before attaching shrouding, the ESP system should be tested.

First, position and support the Hydropanel™ shrouding within

all cable limits (on a chair, etc.). Do not turn on power or water

supply yet.
Shower Applications

Insert the plugs from the proximity

sensor and the solenoid into their

labeled ports on the Control Box

(Figure 5). The unit will not operate

properly if the connectors are not in

their correct ports.

Supply power to the transformer, and activate the sensor by

pressing the pushbutton (Figure 8). The solenoid should make

an audible click.
ESP Shower Time Adjustments
NOTE: To prevent repeat cycling, the Piezo sensor has a five

second "lock-out" after the shower has been turned on or off.

During the five seconds, no matter how many times the push-

button is pressed, the sensor is programmed not to respond.

Also, the sensor is programmed to deactivate the shower if the

button is held in the active position (continuously invading the

proximity sensor's magnetic field).

Shower Applications
The ESP Control Box includes a potentiometer to set maximum

run-time, from 0 to 15 minutes (Factory setting is about 6 min-

utes). To adjust shower time, remove the cover of the Control

Box. Locate the slotted dial in the center of the circuit board

(Figure 5). With a small screwdriver, rotate the dial in small

increments, clockwise for more time, counterclockwise for less.

Turn dial carefully; overadjusting can damage the potentiom-

eter. After each adjustment, test and time the shower.
Re-Attach the Shrouding
The bottom bracket (Figure 4,D) will attach to the wall 25-1/2"

below showerhead height (see Figure 3). Use the bracket as a

template to mark positions for two mounting holes. Drill holes

and attach the bracket.
The chrome plated end cap (Figure 4) on top of the shrouding

has a section marked to be broken out for vertical and horizon-

tal piping clearance. To remove the marked piece, hit it sharply

with a hammer. Do not remove the entire end cap from the

shrouding.
Connect the outlet side of the solenoid to the showerhead pip-

ing by sliding the showerhead nipple (with the shrouding unit)

into the piping assembly. The bottom bracket will fit inside the

shrouding.
Before connecting shrouding with screws, turn on water supply

and activate the sensor to test the system. Water should flow

through showerhead. Press the pushbutton again to deactivate

the shower, then check all connections for leaks.
Use screws to attach the shrouding to the piping bracket and to

bottom mounting bracket (Figure 4, A and C).

1) When a bather presses the pushbutton, the sensor sends a

signal through the control box to the solenoid. The solenoid

opens and allows tempered water to flow to the shower-

head.

2) If the bather presses the pushbutton again, a signal is sent to

the solenoid to close and consequently shutoff the water.

3) If the bather does not press the pushbutton again, water will

automatically shutoff at the pre-set run-time. After shutoff,

the system is ready for the next user.

NOTE: To prevent repeat cycling, the proximity sensor has

a five second "lock-out" after the shower has been turned on

or off. During the five seconds, no matter how many times

the pushbutton is pressed, the sensor is programmed not to

respond. Also, the sensor is programmed to deactivate the

shower if the button is held in the active position (continuously

invading the proximity sensor's magnetic field).
