the hot water faucet on your fixtures until constant water
flows from them. Otherwise, damage to the device may
occur.
Connect the water heater to a GROUNDED OUTLET.
The unit is fitted with a power cord to connect the water
heater to a receptacle. State and local codes must be
adhered to. Install the correct breaker at the circuit
breaker panel.
The water heater was manufactured and wired in ac-
cordance with the UL requirements.
A temperature high limit with manual reset has been
factory installed to interrupt the power supply in the
event of a thermostat failure.
DO NOT use this water heater with any other voltage.
Failure to use the correct voltage may result in personal
injury or property damage.

The water heater is equipped with an adjustable ther-
mostat that automatically controls the water tempera-
ture. The indicator lamp remains lit only when the water
is being heated.
The temperature is adjusted by turning the knob coun-
terclockwise (to the left) to increase the temperature
and clockwise (to the right) to decrease the temperature.
The water heater thermostat can be set to guard against
freezing. This position keeps the internal temperature
above the freezing point.
The piping outside of the water heater and the faucet
are not protected against freezing.
