The heater supplies a constant amount of energy to heat the water based
on the power setting and power level selected. If water flow rate is
reduced, the water temperature will increase. If water flow is increased,
the temperature will decrease
Please allow hot water to run approximately 5-10 seconds for water
temperature to be regulated before hand contact
During colder seasons the ground water temperature will be lower. This
results in a lower hot water temperature. Press UP on front panel or
reduce water flow at faucet to
increase the power setting which will
result in warmer hot water
Do not block the discharge of the pressure relief valve (if installed)
