    - If the unit now operates with water flowing, call Technical Service at
      - NOTE: BE SURE THE ELECTRICITY IS TURNED OFF TO THE UNIT
    - Make sure the printed circuit board is mounted in the correct position. This is the top set of mounting holes (See diagram below). Failure to mount the PCB in the correct position will cause element burn out and may cause further damage to the unit (This board may have been incorrectly positioned if serviced previously).

GENERAL Water outlet/inlet (Top) Out In U.L. rating label Model # = Order Ref. # UP Indicator light Serial number This is how your “ES” model should look when mounted correctly on the wall. Any other mounting configuration will prevent the unit from operating properly. If the unit is mounted correctly and still does not produce hot water, look to see if the indicator light illuminates when the hot water faucet is fully opened. If the indicator light illuminates, turn to page 6.
PAGE 3
The indicator light does not illuminate (When the hot water faucet is fully opened): STEP ONE: Is the circuit breaker switched ON at the main circuit breaker panel? YES NO Go to Step two Run water at the hot water faucet, for a couple of minutes, before turning on the circuit breaker. Then turn on the circuit breaker at the main circuit breaker panel. STEP TWO: The unit will not heat unless sufficient water is flowing through the unit. The minimum acceptable flow rate is about 0.

STEP THREE: In the brass outlet fitting there is a flow restrictor, this is a little black plug. Shut the water off to the unit and then remove the plug from the fitting. Open the faucet fully to see if the light illuminates with water flowing through the unit. UP SP MODELS OUTLET INLET 0.5 gpm flow regulator (The little black plug) inlet filter If the unit now operates with water flowing, call Technical Service at 1-800-334-3393.

STEP FOUR: A multimeter / voltmeter is required to perform the following test. V A DANGER! TURN OFF THE CIRCUIT BREAKER BEFORE PROCEEDING WITH THE NEXT TESTS Set the meter to the single Ohms setting Do not measure continuity, this will not work. Ω The Ohm Symbol (The upside down horseshoe) NOTE: BE SURE THE ELECTRICITY IS TURNED OFF TO THE UNIT Remove the front cover of the unit. At the end of the black heater body there are two threaded silver rods with brass nuts on them (Where the wires connect).
PAGE 6
The indicator light illuminates but water is not heated or the water temperature is too low: STEP ONE: The water flow is too high. Reduce the water flow using the faucet. With experimentation, an increase in temperature should be observed. Make sure the aerator supplied with the heater is attached to the faucet; these are integral for proper performance of the unit. If the special aerator is not included, call Technical Service at 1-800-334-3393 and one will be shipped to you.

Other possible solutions: STEP ONE: NOTE: BE SURE ELECTRICITY IS TURNED OFF BEFORE PROCEEDING. Make sure the printed circuit board is mounted in the correct position. This is the top set of mounting holes (See diagram below). Failure to mount the PCB in the correct position will cause element burn out and may cause further damage to the unit (This board may have been incorrectly positioned if serviced previously).
