NEVER OPERATE THE HEATER WITH THE COLD WATER INLET
VALVE CLOSED OR WITHOUT FILLING WITH WATER PER THE
FILLING INSTRUCTIONS. FAILURE TO DO SO WILL CAUSE DAMAGE
AND CAN VOID ELEMENT WARRANTY.
1. Close the water heater drain valve. (Turn clockwise
2. Open a nearby hot water faucet to permit air to escape.
3. Fully open the cold water inlet valve, filling the heater and piping.
4. Close the hot water faucet when water flows.
5. Turn the water heater electrical switch on.
TEMPERATURE REGULATION
THE WATER HEATER IS EQUIPPED WITH AN ADJUSTABLE
THERMOSTAT TO CONTROL WATER TEMPERATURE. HOT WATER
AT TEMPERATURES DESIRED FOR AUTOMATIC DISHWASHER AND
LAUNDRY USE CAN CAUSE SCALDS RESULTING IN SERIOUS
PERSONAL INJURY AND/OR DEATH. THE TEMPERATURE AT
WHICH INJURY OCCURS VARIES WITH THE PERSON'S AGE AND
TIME OF EXPOSURE. THE SLOWER RESPONSE TIME OF DISABLED
PERSONS INCREASES THE HAZARD TO THEM. NEVER ALLOW
SMALL CHILDREN TO USE A HOT WATER TAP, OR TO DRAW THEIR
OWN BATH WATER. NEVER LEAVE A CHILD OR DISABLED PERSON
UNATTENDED IN A BATHTUB OR SHOWER.
It is recommended that lower water temperatures be used to avoid the
risk of scalding. It is further recommended, in all cases, that the water
temperature thermostats (See Figure 3) be set for the lowest temperature
which satisfies your hot water needs. This will also provide the most
energy efficient operation of the water heater. Thermostat(s) are factory
set at 120°F (49°C) unless specified differently by state requirements.
KEEPING THE THERMOSTAT SETTING AT 120°F WILL REDUCE THE
RISK OF SCALDS.
Figure 3 shows the approximate time-to-burn relationship for normal adult
skin. The thermostats on your water heater have a linear relationship
between degrees of angular rotation and the corresponding change in
temperature. Thus rotating the temperature adjustment indicator 30
angular degrees will result in a 10 degree Fahrenheit change in water
temperature.
TEMPERATURE ADJUSTMENT
To change the temperature setting:
1. Turn off the heater electrical supply. Do not attempt to adjust thermostat
with power on.
2. Remove the thermostat access panels and covers from the
thermostats. Do not remove the plastic personnel protectors covering
the thermostats.

Valves for reducing point-of-use temperature by mixing cold and hot water
are available (See Figure 4). Also available are inexpensive devices that
attach to faucets to limit hot water temperatures. Contact a licensed
plumber or the local plumbing authority.
A non-adjustable high temperature limit control operates before steam
temperatures are reached. The high limit is in the same area as the upper
thermostat and must be reset manually when it operates.
THE HIGH LIMIT OPERATES ONLY WHEN ABNORMALLY HIGH
WATER TEMPERATURES ARE PRESENT, IT IS IMPORTANT THAT A
QUALIFIED SERVICE AGENT BE CONTACTED TO DETERMINE THE
REASON FOR OPERATION BEFORE RESETTING.
Electric water heater maintenance consists of cleaning the tank bottom
and removing scale from the heating elements. Your dealer should be
contacted for tank and element cleaning. In some instances a hissing
sound may be heard as the scale builds up. This noise is normal although
the scale should be removed.
