1.    Carefully read and understand the section, “Water

 

 Temperature Regulation” section of this manual. If  

 

 the instructions are not clear, contact a qualifi ed 

 

 person.

2.    Make sure the water heater has been properly 

 

 installed. See “Installing Your Water Heater” section.

3.    Completely fi ll the tank water, Open faucet to allow 

 

 air to purge (see page 5, step 7).

4.    After the tank is completely fi lled with water, turn on

 

 power to the water heater at the breaker panel.

5.    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 access doors 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 qualifi ed 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 fl ood conditions or any 

time the temperature sensor(s) or electronic thermostat 

have been submerged in water require replacement of the 

entire water heater.

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 fi rmly pushing in the red reset button located 

on the electronic thermostat (see Figure 10A on page 12). 

If the ECO continues to shut-off the water heater contact a 

qualifi ed person.

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 Smart

®

 Module to the preferred setting as shown in 

“Adjusting the Energy Smart

®

 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 temperature past 120° F on the

Energy Smart

®

 Module will increase the risk of scald injury 

in the times shown below. The use of a mixing valve is

When leaving your home for extended periods (vaca-

tions, etc.) set the water heater to Vacation Mode. See 

“Adjusting the Energy Smart

®

 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.
