PART 6 – STARTUP: WHAT TO EXPECT
After the water heater has been installed with all electrical and water connections secure and checked, fill the unit with water. While
filling, vent the tank by opening a hot water faucet somewhere in the home (preferably at the kitchen sink). When water flows freely, the
tank is full.
Once the tank is full, energize the water heater. Press the POWER button on the user interface to turn the water heater on. Once
powered, the control will display a reminder to ensure the water heater is full. Press POWER again to acknowledge that the water
heater is full.
NOTE: Table 5 outlines what can be expected next.
