Temperature regulating thermostat
High Limit thermostat with manual reset
This water heater uses mechanical surface
mounted
thermostats
contactors allowing current to flow to the
immersion heating elements. The standard control
system uses one immersion thermostat for each
36kW of electric heating power in a water heater.
TEMPERATURE REGULATING
THERMOSTATS
This water heater has an adjustable thermostat to
control water temperature. The thermostat is
factory pre-set at approximately 125° F (51.7° C)
or less. Households with small children or
invalids may require a 120° F (48.9° C) or lower
temperature setting to reduce risk of scald injury.
Remember, no water heating system will provide
exact temperatures at all times. Allow a few days
of operation at the setting to determine the correct
temperature setting consistent with your needs.

WATER TEMPERATURE SETTINGS
1. Turn "OFF" the electrical power to the
water heater.
2. Open the thermostat cover on the tank.
3. Adjust each thermostat to the
desired temperature setting by turning the
adjusting knob from hot to very hot
position to increase the temperature.
When the knob is at very hot position the
adjusted temperature is max. 72 ° C. Each
thermostat will be factory pre-set to
approximately 125° F (51.7° C) or less as
shipped.
4. Close the thermostat cover.
5. Turn "ON" the electrical power to the
water heater.
WARNING:
HAZARD OF ELECTRICAL SHOCK –
Before opening the electrical access panel
to adjust the thermostat make sure the
electrical supply to the water heater is
turned "OFF".
HIGH WATER TEMPERATURE
LIMIT CONTROL
The unit is equipped with a fixed setting, manual
reset high water temperature limit control. The
water heater temperature limit control has a fixed
limit setting of 180° F (82 ° C). If water
temperature exceeds the limit set point, the limit
will break the control circuit and shut down the
unit. The limit control can only be reset after the
water temperature has cooled below the set point
of the limit. The high water temperature limit
control is mounted on the surface of the tank,
above the heating element installed at the highest
point in the tank. The high limit control is reset
by pushing the red reset button on the control.
Operation of the limit control usually indicates a
major problem with the thermostat, contactors or
heating elements. Do not continue to push the
reset multiple times. The source of the problem
