STEP 2 VERIFYING POWER TO ELECTRONIC BOARD THE FOLLOWING STEP WILL VERIFY POWER IS GOING TO THE BOARD. TURN OFF ALL POWER TO THE UNIT. REMOVE THE 4 SCREWS FROM THE PLASTIC BOARD PROTECTOR AND REMOVE THE COVER. TURN ON ALL BREAKERS. WHEN BREAKERS ARE TURNED ON THE LED DISPLAY ON THE UNIT WILL TURN ON FOR A COUPLE OF SECONDS AND THEN TURN OFF. THIS INDICATES THAT THERE IS POWER GOING TO THE BOARD.

STEP 3 VERIFYING SAFETY THERMOSTATS THE FOLLOWING STEP WILL VERIFY POWER IS GOING THROUGH THE SAFETY THERMOSTATS. IF A THERMOSTAT IS DAMAGED THE HEATING ELEMENT WILL NOT FUNCTION OR HEAT UP. TO VERIFY THE THERMOSTATS YOU NEED TO HAVE THE BREAKERS TURNED ON. YOU WILL PERFORM THIS TEST WITH YOUR VOLT METER. THIS TEST WILL VERIFY THAT ELECTRICAL POWER IS GOING TO THE BOTTOM AND ACROSS THE THERMOSTAT.

STEP 4-CONTINUED WHEN MEASURING VOLTAGE ACROSSS THE TOP OF THE ELEMENTS YOU WILL GET A VOLTAGE READING. REMEMBER– YOU MUST HAVE WATER RUNNING IN ORDER FOR THE ELEMEMTS TO ACTIVATE AND DRAW POWER. IF YOUR LED DISPLAY IS LIT AND YOU HAVE WATER RUNNING THROUGH THE UNIT AND HAVE 0 VOLTAGE READING WHEN MEASURING WITH PROBES ON EACH SCREW -PERFORM THE SAME TEST, BUT THIS TIME PLACING ONE PROBE ON ONE SCREW AND THE OTHER PROBE TO GROUND. DO THE SAME ON THE OTHER SCREW.

HOW TO SET AND SELECT YOUR TEMPERATURE SETTING. DIFFERENT THAN A STORAGE TANK TYPE WATER HEATER THAT YOU NORMALLY SET THE THERMOSTAT TEMPERATURE BETWEEN 130°F-140°F, SO YOU DO NOT RUN OUT OF HOT WATER TOO FAST WHICH CAN CAUSE HOT WATER SCALDING AND FORCES YOU TO USE MORE WATER BY HAVING TO MIX COLD WATER TO ATTAIN YOUR COMFORTABLE SHOWER OR HOT WATER USAGE TEMPERATURE. THE ECOSMART GUARANTEES YOU UNLIMITED HOT WATER AND THEREFORE IT IS NOT NECESSARY TO SET IT AT A HIGH TEMPERATURE SETTING.
