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.

APPROXIMATE TIME/TEMPERATURE RELATIONSHIPS IN SCALDS
120°F (49°C) More than 5 minutes 140°F (60°C) Less than 5 seconds
125°F (52°C) 1½ to 2 minutes 145°F (63°C) Less than 3 seconds
130°F (54°C) About 30 seconds 150°F (66°C) About 1½ seconds
135°F (57°C) About 10 seconds 155°F (68°C) About 1 second
CAUTION
Before adjusting thermostat(s), turn off power supply to the water heater.
DANGER
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.
