1. Turn off the Power

2. Take each wire pair and connect them to one breaker (see wiring diagram). Make sure that each

breaker is connected with one black wire and one red wire.

3. Using a suitable wire gauge that meets all applicable electrical codes for the size of the breakers

used, run the correct sets of wire from the main breaker panel to the tankless water heater.

4. A separate ground conductor is required.

5. Double-check the electrical connections to make sure they are correct and that all wire connections

are tight and secure.

OPERATING INSTRUCTIONS

CAUTION: Wait until the water is fully flowing through the heater before turning on the breaker.

1. Allow water to flow through the water heater unit. Allow the water to flow continuously to flush out

any debris as well as purge the pipes of any air.

2. Turn on the breaker to power the water heater. A beep sound will be heard and the LED display

will light up. If there is no other display, the appliance will stay in standby.

3. Press the power button on the unit to turn the appliance ON/OFF. When the unit is working, LED

lights will show the Actual Temp.

4. Press + and - to adjust the outlet water temperature. The temperature setting range is 86-131°F

(30-55°C). When heating, the heating icon on the screen will light up.

Caution: If the unit is paused there may be an initial burst of very hot water when resuming.

Please allow the water to flow for a few moments to let the temperature settle. It's always advised

to test the water temperature with your hand before hopping straight into the shower.

5. If the unit will not be used during the winter completely drain out the water to prevent freezing.

6. Periodically clean the water heater's inlet strainer, the faucet aerator, and the shower head to

ensure the free flow of water.
