OPERATING YOUR WATER HEATER
Water Heater Start-Up
1. Carefully read and understand the section, "Water
Temperature Regulation" section of this manual. If
the instructions are not clear, contact a qualified
service technician.
2. Make sure the water heater has been properly
installed. See "Installing Your Water Heater" section.
3. Completely fill the tank water, Open faucet to allow
air to purge (see page 5, step 7).
4. After the tank is completely filled with water, turn on
power to the water heater at the breaker panel.
,
Power to the water heater will allow the water heater
to run a system diagnostic. This typically takes eight
minutes. Once complete, proceed to the next step.
NOTE: if the system diagnostic yields any codes,
reference the Diagnostic Code section in this manual.
6. Adjust the thermostat to the desired temperature
setting as described under "Adjusting the User Inter-
face Module/Operational Modes" section.

IMPORTANT: Operation of this water heater without
access doors or insulation could result in much higher
water temperatures than the desired set point,
increasing the risk of scald injury.
Do not operate water heater with
the accessdoors or insulation
removed.

IMPORTANT: Do not attempt to operate this water heater
if the temperature sensor(s), electronic control board, or
surrounding insulation has been exposed to water in any
way. Immediately call a qualified service technician to
inspect the water heater and replace any temperature
sensor(s), electronic control board, or insulation that has
been exposed to water. Do not attempt to repair these
parts. Water heaters subjected to flood conditions or any
time the temperature sensor(s) or electronic thermostat
have been submerged in water require replacement of the
entire water heater.
Safety Shut-Off
This water heater is designed to automatically shut-off in
the event that the water temperature exceeds 180 ° F
(82.2° C). A temperature limit switch, or ECO (Energy Cut
Off), is used to shut off the power to the system if the wa-
ter temperature exceeds 180 ° F or 82.2 ° C. The ECO can
be reset by firmly pushing in the red reset button located
on the electronic thermostat (see Figure 10Aon page 12).
If the ECO continues to shut-off the water heater contact a
qualified service technician.

Water Temperature
Regulation
Water temperature over 125°F can cause
severe burns instantly or death from
scalds.
Children, disabled, and elderly are at
highest risk of being scalded.
Feel water before bathing or showering.
Temperature limiting valves are
recommended.
The water heater is adjusted to a temperature setting of
no higher than 120° F when shipped from the factory.
Water temperature can be regulated by adjusting the En-
ergy Smarte Module to the preferred setting as shown in
"Adjusting the Energy Smart ¢ Module/Operational Mode".
The preferred starting point is 120° R There is a hot water
scald potential if the temperature set point is set too high.
Important: Adjusting the temperature past 120° F on the
Energy SmarP Module will increase the risk of scald injury
in the times shown below. The use of a mixing valve is
recommended.

When leaving your home for extended periods (vaca-
tions, etc.) set the water heater to Vacation Mode. See
"Adjusting the Energy Smarte Module/Operational Modes"
section. This will maintain the water at low temperatures
with minimum energy losses and prevent the tank from
freezing during cold weather.
NOTE: When returning from an extended stay remember
to set the water heater back to the desired Operational
Mode.
