CAUTION: Wait until 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.

    display will light up for 2 seconds.
3. Press       to turn ON/OFF the appliance. When the unit is ON, the LED will display the 
    water’s temperature. 30 seconds after the flow of water has been stopped the screen will to 
    into energy saving mode. The unit is still ON and the screen will still light up when a button 
    is pressed. 
    Check the product specification page to check minimum water flow for activation.
4. Press       and       to adjust the outgoing water temperature. The temperature setting ranges 
    from 86-125°F (30-52 ° C).
    

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. Press       to convert the temperature display between Fahrenheit and Celsius.
6. The water heater unit will remember and save the previously used temperature on the next 
    use.
7. There is an over-temperature protection system for this unit. When the temperature reaches 
    149 ° F (65 ° C) the system will automatically start to decrease the temperature until it’s back 
    to a safe level. Only then will you be able to increase the temperature again.

● 

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

CLEANING & MANTENANCE

● 

Do not attempt to repair the water heater unit yourself. Please contact a certified professional 

or call our customer support for assistance. It is important to shut off all power to the water 
heater directly at the fuse or breaker. Failure to do so could cause permanent damage to the 
water heater and void the product warranty.

Before performing any maintenance make sure to take precaution and prevent exposure to the 

potentially hot water. The water may be hot enough to present a serious scalding hazard. The 
water should be safely drained to prevent any injury or property damage.

It is recommended to regularly maintenance the water heater. Proper maintenance will help 

lead to a long running, trouble free water heater.

Periodically remove scale and dirt that may build up at the faucet aerator.
