Before reconnecting shrouding with screws, turn on water

supply and activate the sensor to test the system. Water

should flow through showerhead. Deactivate sensor and

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 power is supplied to the ESP system, the sensor

emits a continuous field of infrared beam.

2) A bather that steps into the range of this field activates the

sensor. The sensor sends a signal through the modular

junction box to the solenoid. The solenoid opens and allows

tempered water to flow to the showerhead.

3) When the bather steps out of sensor range, a signal is sent

to the solenoid to close and consequently stop the flow of

water.

4) If the bather does not move away from the sensor, the

shower will run until the pre-set maximum run time.

After shut-off, the system is ready for reactivation.

System Maintenance

Routinely (twice a year) perform the following maintenance to

ensure safe continuous operation of ESP Hydropanel units.
1. Inspect electrical connections for corrosion.
2. Check for any loose connections. Tighten if necessary.
3. Check solenoid valve for proper operation. Make sure it is

free of dirt and lime build up.

4. Check that temperature of supply water is thermostatically

controlled for safe comfortable bathing.

To clean the shower area without turning off the main water

supply, either turn off the electricity to the ESP system (if pos-

sible), or simply apply a strip of dark opaque tape over the

lens. Black electrical tape will work; it absorbs and does not

reflect the infrared light. (The sensor shouldn't activate until

the tape is removed.) A mild soap may be used to clean the

lens, but avoid abrasive cleaners; they may scratch the lens.

Maintenance and Troubleshooting

If red LED on sensor lens (Figure 7) does not light to show

that the sensor has detected a bather:

a. Check that an object was not in front of the sensor when unit

powered up. The sensor will not operate until the object is

removed and the sensor reactivated.

b. Check that transformer feed wires are securely attached to

terminals at modular junction box and at transformer.

c. Check that power is being supplied to the transformer.

Also, use a voltmeter to check that power is being supplied

through the transformer. If power goes into the transformer

but does not come out, replace the transformer.

d. If transformer functions properly and power is supplied, but

LED still does not light, replace sensor assembly.

2. If no water flows from showerhead when bather tries to

activate sensor:

a. Check that the red "sensor activation" LED lights are on.

If not, see #1.

b. Check that the supply line is open and water is being supplied.

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.
Insert the plugs from the infra-

red sensor and the solenoid into the ports on the Modular

Junction Box marked JP1 and JP2. Either plug can go into

either port on the MJB.
Supply power to the transformer, and activate the infrared

sensor by moving an object in front of it. The sensor activation

light on the front of the sensor lens (Figure 6) will turn on to

show proper sensor activation.
ESP Shower Sensitivity Adjustments
Each ESP Infrared Sensor has a potentiometer to adjust range

distance from 2" to 48". The sensor is factory set at 18"—

useful for most applications,

depending on reflectivity of

skin, room lighting, etc.
To adjust, locate the top dial

on the back of the Infrared

Sensor (Figure 7). With a small

screwdriver, rotate the dial in

small increments, clockwise

for more distance, counter-

clockwise for less. Turn dial

carefully; over-adjusting can

damage the potentiometer.

After each adjustment, test the shower.
ESP Shower Time Adjustments
Although each ESP system will shut off the shower when a

bather steps away from the sensor, it also has a potentiom-

eter to set a maximum run-time, from 0 to 14 minutes. Factory

setting is 14 minutes.
To adjust, locate the bottom dial on the back of the Infrared

Sensor (Figure 7). With a small screwdriver, rotate the dial in

small increments, clockwise for more time, counter-clockwise

for less. Turn dial carefully; over-adjusting can damage the

potentiometer. After each adjustment, test and time the

shower.
Reattach the Shrouding
The bottom bracket (Figure 4,D) will attach to the wall
19-1/4" 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.
