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.
For brass solenoid: For maintenance instructions, use Powers
Kit #444 183 and refer to “Installation and Maintenance

The following are problems that may occur with the ESP
Hydropanel™ II. Follow the listed steps toward a solution. For
any further problems, call Powers Application Engineering
Deptartment at 1.800.669.5430.
Shower Control:
1. Iftheshowerdoesnotactivatewhenthepushbutton
ispressed:
a. Check that transformer feed wires are securely
attached to terminals at control box and at transformer.
b. Check that power is supplied to the transformer. Also,
use a voltmeter to check that power is being supplied
through the transformer. If power goes into the trans-
former but does not come out, replace the transformer.
2. Ifnowaterflowsfromshowerheadwhenpushbutton
ispressed:
a. Check that the supply line is open and water is being
supplied.
b. Check that the solenoid wires are securely connected.
c. The maximum run-time may have elapsed. Wait 5
seconds for sensor delay, then press the pushbutton
again. For a longer shower-run time, reset potentio-
meter on control box.
3. Ifwaterrunscontinuously,regardlessofsensoractivity:
a. FIRST unplug solenoid from the control box.
b. If water continues to run...
• Debris and/or lime build-up may be preventing
solenoid from closing. Dismantle, clean and flush the
solenoid valve (see Solenoid Valve Maintenance).
c. If water stops after disconnecting power...
• The problem is electronic. Check that power wires
are connected properly in the Control Box, and check
all electrical connections.
