SECTION V: OPERATION

THE WATER HEATER MUST BE FILLED WITH WATER BEFORE CONNECTING ELECTRIC POWER.
When the branch circuit disconnect switch is closed and electric power is applied to the
water heater, the operation of the water heater will be automatic. Thermostats on single
element and dual element models are factory set to 125°F and 135°F, respectively.
THERMOSTAT TEMPERATURE ADJUSTMENT
Turn off all power to the water heater before unlatching the junction cabinet or
removing an access cover.
If thermostat adjustment is necessary, disconnect all power to the water heater. Open the
junction cabinet or remove the access cover to gain access to the foam dam. Remove the
insert in the foam dam to expose the thermostat and heating element. Do not remove
the plastic protective cover. The temperature knob can be adjusted with a screwdriver.
Thermostats on single element models have temperature markings around the adjustment
knob. Dual element models incorporate thermostats that are marked "lo", "med", and "hi."
See Table 8 for the relationship between markings and temperatures.
Hot water in excess of 120°F can cause scalding! The temperature at which injury
occurs varies with the person's age and the time of exposure. The slower response
time of disabled persons increases the hazards to them. NEVER allow small children to
use a hot water tap. NEVER leave a child or disabled person unattended in a bathtub
or shower.
Replace the foam dam insert and access cover after adjusting the thermostat. On dual
element models, make sure the junction cabinet latch is closed. Reapply power to the
water heater and continue normal operation.
