GENERAL OPERATING INSTRUCTIONS
Operating your new tankless water heater is similar to using any
traditional water heating system. However, it is very important that you
carefully read all of the setup procedures and operating instructions and
tips to ensure the maximum performance and energy savings from your
new water heater. We recommend that all members of the household
read these General Operating Instructions.
How your new water heater works: Your tankless water heater does
not store hot water like a traditional tank-type water heater. It contains
high powered heating elements that are capable of heating water
on-demand. As soon as you turn on a hot water faucet, a sophisticated
flow sensor recognizes that you have turned on the water. This sensor
measures flow rate while another sensor measures the incoming water
temperature. This information is transmitted continually to the computer
logic controls which decide how much power to send to the heating
elements to heat the water to your desired temperature. Once the water
faucet is turned off your water heater will turn off as well.

CAUTION: Removing the cover to change the temperature set point exposes
electrical shock and burn hazards, which can cause INJURY or DEATH.
Adjustment should only be done by a licensed plumber or electrician.
DANGER: Hotter water increases the potential for Hot Water SCALDS.
*CAUTION* BEFORE SWITCHING THE ELECTRICAL BREAKER "ON", VERIFY
THE INLET AND OUTLET BALL VALVES ARE FULLY OPEN AND WATER IS
FLOWING THROUGH THE HOT WATER FAUCET FOR A MINUTE OR TWO
UNTIL THE FLOW IS CONTINUOUS AND FREE FROM AIR POCKETS. DO
NOT SWITCH THE BREAKER "ON" IF THERE IS A POSSIBILITY THE WATER
IN THE HEATER IS FROZEN.

displayed. This is a counter that represents the volume of
water in gallons remaining to pass through the unit before
the unit is considered commissioned.
At this point, water needs to be turned on.
After the counter reaches "0.0", the temperature setpoint
screen is displayed. At this point, the unit is commissioned
