WHAT TO EXPECT FOR "NORMAL START-UP"
Only after the unit has been installed and the electrical & water connections are secure and checked, should the unit
be filled with water (The tank is vented by opening any hot water faucet in the location to permit the tank to fill
completely with water). Once tank is filled with water and electricity is connected, the user must press the POWER
button on the user display interface. The unit will then remind the user to check that the tank has been filled with
water; which is acknowledged by pressing POWER again.
