Experience has shown that improper installation
or system design, rather than faulty equipment, is
the cause of most operating problems.

Excessive water hardness causing a lime/scale
build-up in the heater and/or on the immersion
heating elements is not the fault of the equipment
and is not covered under the manufacturer’s
warranty. (See Water Treatment and Water
Chemistry)

Do not energize electrical system before heater
is completely filled with water.

Damage caused

to the immersion heating elements by dry fire is
not covered under the manufacturer’s warranty.
Follow start up procedure in the manual. 
Water heater corrosion and component failure
caused by air-borne chemical vapors is not
covered under the manufacturer’s warranty.
Corrosion damage caused by current leakage due
to improper grounding of electrical systems or
electronic components to the storage tank and
related piping is not covered by the
manufacturer’s warranty. Under no circumstance
will the manufacturer be liable for consequential
damages resulting from the installation or use of
this equipment. Correct installation procedure
and local codes must be adhered to.

This manual supplies information for the
installation, operation and servicing of the
appliance.  It is strongly recommended that this
manual be reviewed completely before
proceeding with an installation. Upon receiving
