Installation Guide and Manual

IMPORTANT SAFETY INFORMATION
READ ALL INSTRUCTIONS BEFORE USING
10. When the heater is installed in a well
water system or if the plumbing
system is prone to introducing air into
the heater, it is highly recommended
that an air separator be installed in the
cold water feed to the heater to avoid
possible failure of the heating element
and/or heating chamber.
11. In accordance with NEC guideline, this
water heater is designed for a
maximum continuous duty cycle of 3
hours at 100% power output. . After
three hours heater should be powered
down for long enough to return heater
and electrical infrastructure to
ambient temperature. Exceeding this
rating, without proper pause, could
damage the heater and void the
warranty.
12. Provide an uninterrupted supply of
potable water to the heater at a
constant minimum pressure of 35PSI
(based on model) and maximum
pressure of 150 PSI.
13. Use of Water Hammer Arrestors in
applications with excess pipe lengths
or fast acting valves is strongly
recommended. Neglecting to do so will
damage the heater and void the
warranty.
14. This heater must be installed in a
location where it is not subject to
freezing temperatures unless supplied
with factory installed freeze
protection.
15. Properly purge air out of system
before power is applied. Purge water
through the system for a minimum 2
minutes at the maximum flow
available. During this process, close
and open the drain valve 3 times to
dislodge any air before power is
applied. Utilizing the recommended
boiler drain on the outside of the
heater is an acceptable means to
purge the system.
16. Applications located above the point
of use, i.e. in a drop ceiling must take
additional precautions for continuous
air elimination to prevent
interruptions to the hot water service.
Use of an air separator/scrubber is
required for this type of installation.
