a. Reset the ECO by pushing in the red button marked “RESET”.
b. Adjust water temperature by turning the white adjustment knob. Turning the knob to the right (clockwise) makes the water
hotter. Turning the knob to the left (counterclockwise) makes the water cooler.
Risk of scald injury increases as you increase water temperature.
STEP #5
– Replace the insulation.
Failure to replace insulation could result in property damage, severe personal injury, or death.
STEP #6
– Reattach the access cover with the two screws.
STEP #7
– Restore power by replacing the fuse or turning on the circuit breaker.
STEP #8
a. After resetting the ECO, ensure the water heater is operating properly before leaving the installation.
b. After adjusting the water temperature, allow the water heater enough time to heat the water to temperature. After the water
heater has stopped heating, measure the water temperature at a hot water outlet in the structure.
STEP #9
– If the water heater is operating properly and the water temperature is satisfactory, adjustment is complete.
C. HEATING ELEMENT REPLACEMENT PROCEDURE
If heating elements need replacement, it is very important to use the same voltage, wattage, and construction. The element sheath
must be incoloy and the hex plug must be made of stainless steel.
STEP #1
– Turn off power to the water heater. Use a Phillips Head screwdriver to remove wires connecting the element to the
thermostat.
Failure to disconnect power from water heater before attempting heating element replacement will result in property damage, severe
personal injury, or death due to electric shock.
STEP #2
– Run hot water at a faucet in the system. When it runs cold, shut off the faucet. Then shut off water at the main cold water
inlet, or, if possible, valve off the water heater from the system. Drain the water from the system, or just the water heater if you can
isolate it from the system.
Completely drain the water heater before removing and replacing a heating element or elements. Failure to do so will result in a
leakage of water and property damage, and could possibly result in moderate to severe personal injury or death.
Water drained from the water heater may be scalding hot. Take care to avoid scalding. Wear gloves and safety glasses, and direct
water to a safe drainage location. Failure to comply with this warning could result in substantial property damage, severe personal
injury, or death due to scalds.
