MAINTENANCE
Your new electric tankless water heater requires no maintenance. However, to ensure maximum performance of
your water heater and to reduce the risk of a water leak, we do 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, leakage or weakness should be replaced. 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 ELEMENTS.
If you have a water supply with a high level of mineralization (hard water), you should increase the frequency of
your maintenance.

All units are thoroughly tested before they leave our factory. In rare instances, your unit could arrive with internal
or external damage that may affect its performance. All units are factory tested as follow:
PRESSURE INTEGRITY TEST
Each unit is pressure tested to insure against leaks. We test at 180 psi of water pressure which is much greater that
the unit will experience in a typical residential installation.
ELECTRICAL INTEGRITY TEST
Each unit is tested to verify that there are no short circuits and that the unit’s circuitry is properly configured
(Die electric voltage test).
SPECIFICATIONS LEVEL TEST
Each unit is temporarily attached to a testing station that duplicates the conditions present in a typical residential
installation. The unit is turned on and the temperature of the water produced by the unit is measured at several
flow rates to insure that the proper temperature rise specifications are met and that the unit self-regulates with the
varying flow rates.
