5) SETTING THE TEMPERATURE

At this point, the water temperature may not be

very hot. Using the OUTLET BALL VALVE, slowly

reduce water flow until the desired temperature is

achieved. Always keep the INLET BALL VALVE fully

“OPEN”. NEVER RESTRICT THE WATER FLOW

USING THE INLET VALVE. The temperature is

proportional to the flow through the heater; the

lower the flow, the higher the temperature and

vice versa.

If water flow is TOO HOT follow the instructions below according to what model Eemax heater you have:

”Single Point/Flow Controlled” or “Thermostatic”.

“Single Point” and “Flow Controlled” heaters have

a circuit board that looks like this:

“Thermostatic” heaters have a circuit board that

looks like this:

These heaters have no

controls on the circuit

board to turn the

temperature of the

water DOWN.

Volume of water through these heaters is the way

maximum temperature is controlled. If the outlet

valve is adjusted to less than wide-open, open it

up to maximum flow. You may have to change the

faucet aerator to a larger size (0.5 GPM to 1 GPM,

for example) to reduce temperature.

The thin blue temperature adjustment shaft in the

upper left corner controls the maximum

temperature of the water. If the water is too hot:

turn the temperature adjustment shaft counter-

clockwise about 1/8 of a turn and wait 15-20

seconds. If the temperature remains too hot,

repeat this step until the desired temperature is

achieved.

Congratulations !

Your Eemax tankless electric water heater is fully installed and ready for use!
