GENERAL OPERATING INSTRUCTIONS
Operating your new tankless water heater is very similar to using any traditional water heating system.
However, it is very important that you carefully read all of the set-up 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 conventional
tank-type water heater. It contains very high powered heating elements that are capable of heating water on-
demand. As soon as you turn on a hot water faucet, a sophisticated f low 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.

MAINTENANCE
To ensure maximum performance of your water heater and to reduce the risk of a water leak, we recommend the
following maintenance:
You should inspect the connections on the inlet and outlet of the water heater at least on an annual basis for any
signs of damage or failure. Any signs of damage, cracks, leakag e or weakness should be address. Take care not
to over-tighten the connections. Serious internal damage to your water heater can occur if you over- tighten the
water heater connections at the unit.
IMPORTANT NOTES:
As with all electrical appliances, under no circumstances should you attempt to install, repair or disassembled this
water heater without first shutting off all power to the unit directly at the fuse or breaker box. SERIOUS BODILY
INJURY OR DEATH COULD OCCUR IF YOU IGNORE THIS WARNING.
When any maintenance is performed on the water heater or the home’s plumbing system that may introduce air
into the plumbing pipes, it is important to turn the power off to the water heater and purge the air out of the
lines before allowing the unit to power up. FAILURE TO DO SO COULD CAUSE PERMANENT DAMAGE TO THE HEATING
ELEMENT AND VOID YOUR WARRANTY.
If you have a water supply with a high level of mineralization (hard water), you should increase the frequency of your
maintenance.
