Turning on the water heater.
The first time you press the power button and the
water heater is powered on, the screen will ask
for confirmation that the tank has been filled with
water. The tank must be full of water before the
heater is turned on to prevent damage.
The water heater warranty does not cover damage
or failure resulting from operation with an empty
or partially empty tank. (Refer to the Certificate
of Limited Warranty for complete terms and
conditions.)
If the tank has nOT been filled, vent and fill tank
with water before pressing the
POWER
button
again.
• Make sure the drain valve is completely closed.
• Open the shut-off valve in the cold water supply
line.
• Open each hot water faucet slowly to allow the
air to vent from the water heater and piping.
• A steady flow of water from the hot water
faucet(s) indicates a full water heater.
After the tank has been filled with water, press the
POWER
button again.
Once the water heater has been powered on, the
main screen will be shown. The display will show
the current water temperature setting and the
current operating mode for the water heater.
To comply with safety regulations, the controls are
factory preset to 120°F (49°C) and Hybrid Mode. It
is recommended that the unit be set to eHeat™
mode to maximize energy savings. Operating in
Hybrid mode provides a balance of energy savings
and hot water use convenience. Reported energy
consumption is based on operating the unit in
Hybrid mode at a temperature setting of 135°F
(57°C), and operation at lower temperature settings
or in eHeat™ mode will provide even greater
energy savings.
If the display goes blank, press any key to reactivate
the display. To go back to the default (
HOME
) screen,
press the left arrow button until the default (
HOME
)
screen appears.
