WARNING
• 24Vac transformer is used for a single shower application.
• Do not allow power transformer wires to touch during wiring, since this could cause permanent damage to the transformer. To avoid this, do not supply power to, or plug in, the transformer until all other wiring is complete.
• Since solenoid valves require water free of sand, grit, etc., to operate properly, flush water lines until water is free of those materials before connecting solenoid valve.
• All electrical wiring and plumbing should be done in accordance with national/local codes and regulations.
• We recommend the use of stainless steel screws for installation of all components.
TOOLS REQUIRED:
• Slotted and Phillips screwdrivers
• Drill
• Pipewrenches
• Pipe dope/sealing compound
Powers ESP Infrared Showers are supplied with a brass
Solenoid Valve, into which tempered water should be connected. A Powers thermostatic mixing valve, such as the Hydroguard Series LFLM495, will ensure safe comfortable water is supplied to your shower system.
Description
Hydroguard ESP infrared shower systems rely on infrared technology to sense the presence of a user and to immediately turn on a water supply. The shower automatically shuts off when the bather steps out of the invisible beam of infrared light, or when the maximum shower time has been reached. The shower time is field adjustable 1 minute 30 seconds to 2 hours and 30 minutes.
All showers are supplied complete with the sensor assembly, box transformer, solenoid valve, control box and mounting hardware.
The following instructions will serve as a guide when installing the Powers ESP sensor operated showers. As always, good safety practices and care are recommended when installing electrical equipment. We suggest that you follow the procedures outlined. If additional assistance is required, please call the Powers Application Engineering Department at (800) 669 5430.

Installation
Step 1: Determine Shower Component Layout
Several components, including the shower sensor, control box, solenoid and transformer, will need to be installed to ensure proper operation of the infrared shower system.
Box transformer
Finished wall
The first location to be identified should be the shower sensor… the sensor is housed in a
Stainless Steel Plate designed for surface mounting onto the shower wall. Once the sensor location is determined, you can decide on the location of the other components—the solenoid and sensor are typically located within 2 feet of the control box, but you can use 4 conductor flat telephone cable and connectors to locate the components up to as far as
100' away from the sensor.

Step 2: Install Solenoid
To facilitate servicing, you may wish to install a service stop directly upstream of solenoid. Prior to installing solenoid, flush lines to be sure supply water is free from grit and sand. Solenoid end connections are
3/4" NPT.
Using thread sealant on male threads only (do not use teflon tape), connect supply line to solenoid, checking to be sure the flow is in the proper direction (flow arrow is marked on solenoid body). For normal operation, check to be sure the solenoid manual override is in the
“off” position or water will flow regardless of sensor activation/deactivation.
Connect outlet side of solenoid to showerhead piping.
Step 3: Install Control Box
Keeping in mind that the solenoid and sensor must be within 2 feet of the control box (unless you’re using extra cables and connectors), determine the location for mounting. Using the base of the box as a template (cover should be removed by unscrewing the 4 screws and taking the cover off), drill two small holes and using two screws through the holes on the base plate, mount and tighten to the wall.
See figure 3.

The solenoid valve should be located as close as possible to the showerhead it is servicing. Access to the valve must be provided for maintenance and servicing.
Suggested height for mounting of the sensor for adult men and women is approximately 41"… adjustments to height should be made for adolescents and children. Measure the proper height from the floor… mark shower sensor location with a pencil. Using a 5/8" drill bit, drill hole for sensor connection cord.
Once you’ve pushed the shower sensor cord through the hole, use the stainless steel plate as a template, marking the location of the mounting screws. The shower sensor assembly can be mounted to a 4 x 2 x 23/16" deep electrical box with screws provided, although it is not necessary to do so. If installing onto wall, drill 2 mounting holes (refer to figure 2) and install the sensor assembly.

(“J” box should be mounted inside chase wall or above ceiling). Run wires from secondary side of transformer to control box enclosure.
To avoid permanent damage to the transformer, sensor, or solenoid valve, do not supply power to
24V AC
Secondary primary side of transformer until all wiring has been completed.
Connect transformer wire to power connector. Connect solenoid wire, and sensor wire to JP1,
JP2 or JP3 plugs. Secure control box cover over base and tighten screws.

Step 4: Start Up
Supply power to transformer.
Activate the sensor and check to be sure the small red activation light appears in the bottom of sensor lens. (Refer to figure 5.)
Red indicator light
Figure 5
If the light is on, the sensor is properly operating… turn on
Sensor Assembly Activation Light water supply and reactivate sensor. Water should come through showerhead. Once water is flowing, check all connections for leaks.
Step 7: Secure Sensor Assembly
Once final adjustments have been made to sensitivity and runtime potentiometers, secure the sensor assembly using the two screws supplied. We also suggest using plumber’s putty gasket (not supplied) around stainless steel plate to prevent water leakage behind the wall. To clean, use a mild soap and water, paying special attention to ensure no abrasive cleaners are used on the lens, since scratching may occur.
Operation
Step 5: Sensitivity Adjustment
Shower applications, the Sensor is factory set to provide a proper sensitivity/distance range for most applications (18≤ from sensor eye, depending on reflectivity of skin, lighting, etc.).If range is acceptable, proceed to step 6. If range adjustment is required, you can adjust as follows.
Remove sensor assembly from wall and look at back side. You’ll see two potentiometers (see figure 6). The bottom potentiometer is for adjustment of the range, from 1" to 28". Using the small screwdriver provided, rotate the potentiometer in small increments: clockwise to increase the range, counterclockwise to decrease the range. After each adjustment, check to see if range is acceptable.
Make adjustments carefully. Over-adjustment can damage potentiometer.

Step 6: Shower Time Adjustment
Although the shower will shut off when bather steps away from the infrared sensor, the shower can also be set to automatically shut off after a maximum shower time, from 1 minute 30 seconds to 2 hours
30 minutes. The Sensor Assembly is factory set to provide the shower time of 14 minutes. If that shower time is acceptable, proceed to step 7. If shower time adjustment is required, it is easily adjusted as follows.
Remove sensor assembly from wall and look at back side. You’ll see two potentiometers (see figure 6): the upper one is for adjustment of the shower run time from 1 minute 30 seconds to 2 hours 30 minutes. Using the small screwdriver provided, rotate the potentiometer in small increments: clockwise to increase the shower time, counterclockwise to decrease the shower time. After each adjustment, check

1. A continuous invisible infrared light beam is emitted from the sensor assembly.
2. The shower is activated by bather stepping within the adjustable range of sensor. Immediately after sensor activation, tempered water flows for as long as the user remains within the range, up to the set maximum shower time.
3. When the bather steps away from the sensor, the water flow stops automatically. After preset shower time, the flow of water stops to prevent water waste. It is then ready for the next user, or for reactivation by the present user.
Maintenance and Troubleshooting
To clean the shower area but avoid turning off the main water supply, simply place dark, solid tape (perhaps black electrical tape) on top of the lens, to block out all light. The sensor should not activate until the tape is removed. Note that a mild soap may be used to clean the lens, but abrasive cleaners should be avoided.
To ensure trouble-free performance, routine maintenance is required.
• Check all electrical connections, making sure they are free of corrosion and well connected.
• Check solenoid valve to ensure that it is operating properly and is free of dirt and lime build up.
• Check to be sure the tempered water being supplied to the shower is at the proper temperature for safe comfortable bathing.
If the shower does not function properly:
1. Is the red sensor activation light on in the sensor assembly lens, upon sensor activation? If red LED is not lit after sensor is activated,
• check to see if transformer feed wires are securely attached to terminals at modular junction box and at transformer.
• check to see if there is power to the transformer, using a voltmeter. If power is going into the transformer but not coming out of the transformer, replace transformer.
• if transformer is functioning properly and power is being supplied, replace sensor assembly.

NOTICE
If object is within the range of the Sensor when unit is powered up, the Sensor will not operate until the object is removed and Sensor reactivated.
2. If sensor light is lit upon sensor activation, but no water comes from showerhead,
• check to be sure supply line is open and water is being supplied.
• check to see whether solenoid is functioning… check to be sure manual override is in “off≤ position. If system still fails to operate, repair or replace solenoid assembly (see solenoid repair information above).
• maximum run time may have been reached… sensor will remain lit although solenoid will close to stop water from flowing. If additional shower time is desired, reset run time potentiometer on back of sensor assembly.
3. If water is on all the time, regardless of sensor activation, unplug solenoid from control box. If water continues to run, problem is manual and can be rectified by checking the following:
• check for debris and/or lime build-up within the solenoid, which is preventing it from closing. Dismantle, clean and flush the solenoid valve.
If, after unplugging solenoid from control box, water stops, problem is electronic. Check to see if power wires are incorrectly connected within control box. Refer to instructions above and rewire, checking electrical connections.
