PAGE TWO SP-MODELS Water outlet/inlet (Top) out in U.L. Rating label Model # = Order Ref. # UP indicator light EemaX This is how your Eemax “SP” model should look when mounted correctly on the wall. Any other mounting configuration is wrong and the unit will not work! Check to see if you have an ” SP” model on the U.L. rating label on the front cover of your Eemax unit.

PAGE THREE The Indicator light does not come on (when the hot water faucet is opened): STEP ONE: Is the circuit breaker switched on at the breaker panel? YES NO Go to Step two Run water at the hot faucet for a couple of minutes before turning on the breaker. Turn on breaker. STEP TWO: The unit won’t switch on unless enough water is flowing through the heater. You will need a flow rate of about 0.5 gallons per minute (1/2 gpm). Measure the flow rate.

PAGE FOUR STEP THREE: In the brass outlet fitting there is a flow restrictor This is a little black bung. Shut the water off to the unit and then remove the bung from the fitting. Now replace the fitting and with the faucet open fully see if the light comes on now, with water flowing through the unit. UP SP MODELS OUTLET INLET 0.5 gpm flow regulator (The little black bung) inlet filter If the heater now turns “on” with water flowing, call Eemax at 1-800-543-6163.

PAGE FIVE STEP FOUR: You will require a multimeter / voltmeter to carry out the next tests. V A Ω DANGER! TURN OFF THE 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 horse shoe) Remove the heater cover, at the end of the black heater body there are two threaded silver rods with brass nuts on them. (where the wires go). Take a reading of the ohms value between these two rods.

PAGE SIX The Indicator light comes “on” but there is no heat or the water temperature is low: STEP ONE: The water flow is too high. Reduce the water flow using the faucet, with experimentation you should notice an increase in temperature. Make sure the aerator supplied with the heater is attached to the faucet, these are integral to the proper performance of your heater. If you do not have the special Eemax aerator call Eemax at 1-800-543-6163 and we will send you one.

PAGE SEVEN Other possible solutions: STEP ONE: 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 board in the correct position will cause element burn out and may cause further damage to your heater. (This board may have been incorrectly moved when serviced previously.)
