NOTE: Households with small children, disabled, or elderly
persons may require a 120°F. or lower thermostat setting
to prevent contact with "HOT" water.
The temperature of the water in the heater is regulated by
the adjustable surface mounted thermostat(s) located
behind the Jacket Access Panel(s). Dual element heaters
have two thermostats. To comply with safety regulations
the thermostat(s) were set at 120° F. before the water
heater was shipped from the factory.

There is a Hot Water SCALD Potential if the thermostat is
set too high.
Mixing valves for reducing point of use water temperature
by mixing hot and cold water in branch water lines are
available. Contact a licensed plumber or the local plumb-
ing authority for further information.
