OPERATING YOUR WATER HEATER
Before Using
1. Make sure the water heater has been properly
installed. See “Installing Your Water Heater” section.
2. Completely fill the tank with water by following the
instructions in the “Filling the Water Heater” section of
this manual (see Figure 2).
3. After the water heater tank is completely filled with
water, connect electrical power to the water heater.
4. Read the “Water Temperature Regulation” section of
this manual. If the instructions are not clear, contact a
qualifi ed person.
5. Adjust the thermostat to the desired temperature
setting as described in the “Water Temperature
Regulation” section.
IMPORTANT: Do not attempt to operate this water heater
if the thermostat(s), or surrounding insulation has been
exposed to water in any way. Immediately call a qualifi ed
person to inspect the water heater and replace any
thermostat or insulation that has been exposed to water.
Do not attempt to repair these parts. Water heaters
subjected to fl ood conditions or any time the thermostat(s)
have been submerged in water require replacement of the
entire water heater.
Safety Shut-off
This water heater is designed to automatically shut-off
in the event that the water temperature exceeds 77°C
(170°F). A high limit control switch is used to shut off the
power to the elements if the water temperature exceeds
77°C (170°F). The high limit control switch can be reset by
fi rmly pushing in the red reset button located on the switch.
Follow the instructions under “Resetting the High Limit
Control”, section to properly reset the high limit control. If
the high limit control switch continues to shut-off the water
heater contact a qualifi ed person for service.
Water Temperature Regulation
The thermostat is adjusted to a temperature setting
of “OFF” when it is shipped from the factory. Water
temperature can be regulated by adjusting the thermostat
to the preferred setting. There is a hot water scald potential
if the thermostat is set too high. IMPORTANT: Adjusting
the thermostat past 49°C (120°F) on the thermostat will
increase the risk of scald injury in the times shown below.
To change the temperature setting:
The white knob on the front of the water heater is the
temperature control. When the “OFF” mark is aligned
with the indicator light, the water heater is off. Turn
the knob clockwise to increase the temperature, and
counterclockwise to decrease the temperature. The knob
is marked with circular indentations of increasing size. The
larger the indentation, the higher the temperature setting
(see Figure 8). The temperature settings of this water
heater range from 20°C (68°F) at the lowest setting to
66°C (150°F) at the maximum setting. There is a mark on
the knob indicating 49°C (120°F) and this is a good initial
temperature setting.

Temperature limiting valves are available.
Feel water before bathing or showering.
Children, disabled and elderly are at highest
risk of being scalded.
Water temperature over 52°C (125°F) can
cause severe burns instantly or death from
scalds.
