GENERAL UP Serial number Indicator light U.L. Rating label Model # = Order Ref. # Out In Water outlet/inlet (Bottom) This is how your “EFC” model should look when mounted correctly on the wall. Refer to the U.L. rating label on the front cover of the unit to verify the unit is an “EFC” model before continuing. Any other mounting configuration will prevent the unit from operating properly.

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 Go to Step two NO 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 0.55 gallons per minute.

STEP THREE: 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).

The indicator light illuminates but water is not heated or the water temperature is too low: STEP ONE: The water flow rate is too high. Reduce the water flow using the faucet. With experimentation, an increase in water temperature should be observed. BE CAREFUL, THE WATER EXITING THE FAUCET IS HOT. SCALD INJURY CAN OCCUR FROM THE HOT WATER. STEP TWO: Make sure the unit is connected to the voltage supply specified on the U.L. rating label located on the front cover of the unit.

STEP TWO Inspect the inlet filter (See diagram above for location). Make sure the inlet filter screen is free from debris, pipe dope or any other foreign materials, which may prevent adequate water flow. IF HAVING CARRIED OUT ALL THE TESTS LISTED ABOVE AND THE UNIT IS STILL NOT FUNCTIONING, PLEASE CALL TECHNICAL SERVICE AT 1-800334-3393. PLEASE HAVE THE FOLLOWING INFORMATION AVAILABLE: 1) ORDER REF.
