during shipping or installation. See "Repair Parts Illustration"
section.
Completely fill the tank with water (See "Water Piping"
section).
After the water heater tank is completely filled with water,
connect electrical power to the water heater.
Read the "Water Temperature Regulation" section of this
manual. If you do not fully understand these instruction,
contact a qualified person.
Press the power button (See Figure 16)to turn thewater heater
on and allow itto run asystem diagnostic check. This typically
takes eight minutes. Once complete, proceed tothe next step.
NOTE: If the system diagnostic check yields any codes,
reference the Diagnostic Code section in this manual.
Adjust the thermostat to the desired temperature
setting as described under "Adjusting the User Interface
Module/Operational Modes" section.
IMPORTANT: Do not attempt to operate this water heater if the
unit has been submerged, subjected to flooding, or surrounding
insulation has been exposed to water in any way.
Do not attempt to repair a unit subjected to flood conditions.
Water heaters subjected to flood conditions or any time the unit
has been submerged in water require replacement of the entire
water heater.
Temperature Regulation
Water temperature over 125°F
(52°C) can cause severe burns
instantly resulting in severe injury
or death.
Children, the elderly, and the
_),__, hysically or mentally disabled
are at highest riskfor scald injury.
Feel water before bathing or
.__ showering.
Temperature limiting valves are
available.
Read instruction manual for safe
,, temperature setting.
HOTTER WATER CAN SCALD: Water heaters are intended
to produce hot water. Water heated to a temperature which
wilt satisfy clothes washing, dish washing, and other sanitizing
needs can scald and permanently injure you upon contact. Some
people are more likely to be permanently injured by hot water
than others. These include the elderly, children, the infirm, or
physically/mentally handicapped. If anyone using hot water in
your home fits into one of these groups or if there is a local code
tap, then you must take special precautions. In addition to using
the lowest possible temperature setting that satisfies your hot
water needs, some type of tempering device, such as a mixing
valve, should be used at the hot water taps used by these people
or at the water heater. Mixing valves are available at plumbing
supply or hardware stores. Follow manufacturers instructions for
installation of the valves, Before changing the factory setting of
the thermostat see Temperature Settings table at right.
Never allow small children to use a hot water tap, or to draw
their own bath water. Never leave a child or handicapped person
unattended in a bathtub or shower.
The water heater is adjusted to a temperature setting of no
higher than 120°F when it is shipped from the factory. Water
temperature can be regulated by adjusting the User Interface
Module to the preferred setting as shown in "Adjusting the
User Interface Module/Operational Mode" The preferred
starting point is 120°F. There is a hot water scald potential if
the temperature set point is set too high.
IMPORTANT: Adjusting the set point above 120°F on the User
Interface Module will increase the risk of scald injury in the
times shown below.

NOTE: Water temperature range of 120°m140°F (49°-60°C)
recommended by most dishwasher manufacturers.
Adjusting the User Interface Module/
Operational Modes
The water temperature setting can be adjusted from 95°F to
150°F. Use the Up and Down Buttons _ | on the
front panel to set the desired temperature.
NOTE: The temperatures displayed on the User Interface are
approximates. The actual temperature of the heated water
may vary.
IMPORTANT: Before attempting to adjust the thermostat, read
the "Water Temperature Regulation" section. If the instructions
are not clear, contact a qualified person.
IMPORTANT: Filling a spa or hot tub from this water heater
may result inextended recovery/re-heat time. Hybrid mode will
provide the shortest recovery.
