ECOSMART TROUBLE SHOOTING GUIDE MODELS ECO18-ECO27 THIS STEP BY STEP TROUBLE SHOOTING GUIDE IS DESIGNED FOR THE INSTALLER IF ANY ISSUES ARISE WITH TANKLESS WATER HEATER. YOU CAN ALSO VIEW A TROUBLE SHOOTING VIDEO AT OUR WEB SITE.
Step by Step Trouble Shooting Guide This Guide is for Use by Qualified Electrical Professional This Trouble Shooting Guide will take you through simple steps to determine any problems or issues with unit. This Guide takes you through a sequence of steps that MUST be followed. Skipping around might not determine the exact problem, therefore you MUST follow the sequence.
DISCONNECT ALL POWER TO UNIT BEFORE REMOVING COVER. STEP 1 ELECTRICAL CONNECTION MODELS 21-24-27 ARE SUPPLIED WITH A 6 PRONE TERMINAL BLOCK MARKED (L1 L1) (L2 L2) (L3 L3). MODEL 18 IS SUPPLIED WITH A 4 PRONE TERMINAL BLOCK MARKED (L1 L1) (L2 L2) EACH ONE OF THE CONNECTION SETS MUST BE CONNECTED TO AN INDEPENDENT DOUBLE POLE 40 AMP BREAKER. L1-L1 GOES TO ONE 40 AMP DOUBLE POLE BREAKER, L2-L2 GOES TO ANOTHER 40 AMP DOUBLE POLE BREAKER AND L3-L3 TO ANOTHER 40 AMP DOUBLE POLE BREAKER.
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 LID 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.
