Thermostat Adjustment
The temperature of the water can be changed by adjusting the thermostat(s).
Before any work is done on the water heater, disconnect all power to the
water heater by opening the switch at the main electrical circuit breaker or
fuse box. Remove the access panels or front panel on table tops, fold the
insulation outward away from the controls. Set the thermostat(s) to the
desired water temperature using a screwdriver to move the thermostat dial.
The thermostat has been factory preset to approximately 120°F (49°C).
Rotate the temperature dial clockwise to increase water temperature.
Replace the insulation making sure that the controls are well covered and
that the plastic terminal shield has not been displaced; replace the access
panel. The water heater is now ready for operation and the main switch can
be closed.

CAUTION
Before adjusting thermostat(s), turn off power supply to the water heater.
Hotter water increases the risk of scald injury. Scalding may occur within
five (5) seconds at a temperature setting of 140°F (60°C). To protect
against hot water injury, install an ASSE approved mixing valve in the water
system. This valve will reduce point of discharge water temperatures by
mixing cold and hot water in branch water lines. A licensed plumbing
professional or local plumbing authority should be consulted.
Note: This water heater is equipped with an energy cut out device to
prevent overheating. Should overheating occur, turn off the electrical
supply to the water heater and contact a qualified service technician.
