INSTALLATION GUIDELINE
Install the water heater in a dry, clean area,
●
as close to the target faucet/shower as
practically possible. Avoid installing in rooms
that are subject to freezing temperatures or
corrosive atmosphere. Long uninsulated hot
water lines can waste energy and water.
NOTE: Make sure the water heater and hot
water outlet pipe are out of the reach of
children to avoid tampering with the controls
or burn themselves on hot water outlet pipe.
Moving the water heater or other appliances
to provide service to the water heater is not
covered under warranty.
If a check valve is present on the inlet
●
water line, it will create a "closed system."
Heating water in a closed system creates
an increase in pressure within the water
system because the pressure is not able to
dissipate in the main supply line. Referred to
as "thermal expansion", the rapid pressure
increase can cause the relief valve to operate
(releasing water) during each heating cycle,
potentially causing premature failure to the
valve or even the water heater. The
suggested method of controlling thermal
expansion is to install an expansion tank in
the cold water line between the water heater
and the check valve. Contact your installing
contractor, water supplier, or plumbing
inspector for additional information.
WARNING
It is recommended for this product to be
●
installed by a licensed and qualified
electrician in accordance with all applicable
national, state, and local electrical codes.
Under no circumstances should you
●
attempt to install, repair, or disassemble the
water heater without first shutting off power
directly at the fuse or breaker.
There must be sufficient clearance between
●
any object and the top, rear and sides of the
water heater in the event service is needed.
The controls and plumbing connections at front
of unit must have clear access for operation and
service.
Recommended Minimum Clearances:
12" above and below the water heater
6" in front and to both side of the water heater.
A separate branch circuit with copper
●
conductors, overcurrent protective device and
suitable disconnecting means must be provided
by a qualified electrician.
All wiring must conform to local codes or latest
●
edition of National Electrical Code ANSI/NFPA
70.The voltage requirements and wattage load
for the water heater are specified on the rating
label on the front of the water heater.
The branch circuit wiring should include either:
●
1. Metallic conduit or metallic sheathed cable
approved for use as a grounding conductor and
installed with fittings approved for the purpose.
2. Nonmetallic sheathed cable, metallic conduit
or metallic sheathed cable not approved for use
as a ground conductor shall include a separate
conductor for grounding. It should be attached to
the ground terminals of the water heater and the
electrical distribution box.
Before installing this product, make sure the
●
installation location has sufficient electrical
power available to handle the maximum
amperage load for the water heater.
Proper ground connection is essential. The
●
presence of water in the piping and water
heater does not provide sufficient conduction
for a ground. Nonmetallic piping, dielectric
unions, flexible connectors, etc., can cause the
water heater to be electrically isolated. Do not
disconnect factory ground.
