3.8.2 Electrical Wiring:
Ground And Surges
Δ All units come with a factory installed 3-pronged
(grounded) 120 VAC plug. The tankless
water heater can be plugged into any standard
electrical duplex outlet close to the unit as it
requires only 1 Amp. Always check to make
sure that the appliance is securely grounded.
Δ This requirement is only satised if it has been
properly connected to an efcient ground system
installed in accordance with the requirements
of current safety standards and carried out by
professionally qualied personnel.
Δ The tankless water heater must be electrically
grounded. Ensure the electrical receptacle,
in which the water heater will be plugged into,
is properly grounded; if wiring directly, do not
attach the ground wire to either the gas or the
water piping as plastic pipe or dielectric unions
may isolate the water heater electrically.
Δ The use of a surge protector is recommended to
protect from power surges.
Δ Do not power the unit until all plumbing and gas
piping is complete and the unit has been lled
with water.
Δ The electrical voltage required by the water
heater is 120VAC at 60Hz with a maximum
1 Amp rating with proper grounding. DO NOT
apply 220-240VAC or any other voltage to this
unit. This will damage the water heater and void
the warranty.
Δ Do not disconnect the power supply when the
unit is in normal operation.
Δ If there is a power failure in cold weather areas,
the freeze prevention system in the water heater
will not operate and may result in freezing of
the heat exchanger; in cold weather areas
where power failures are common, you must
completely drain the unit to prevent damage if
the power will be off for any extended period of
time.
Δ Damage caused by freezing is not covered
under warranty.
Δ CAUTION : Label all wires prior to disconnection
when servicing controls. Wiring errors can
cause improper and dangerous operation. Verify
proper operation after servicing.
Δ The connection to the main power supply
must be carried out by professionally qualied
electrical personnel, registered in accordance
with current legislation and local authorities.
Δ Always check to make sure that the appliance
has a sufcient ground. This requirement is only
satised if it has been properly connected to an
efcient ground system installed in accordance
with the requirements of current safety
standards and carried out by professionally
qualied personnel.
Δ This basic safety measure must be checked,
veried and carried out by professionally
qualied personnel.
Have the electrical system checked by a
qualied electrician. The manufacturer will
not be held liable for any damage or injury
caused as a result of an inefcient or faulty
ground system.
If the unit fails to re-start after any fault,
unplug the unit for 30 seconds, then re-plug
in the unit and try to restart with the
ON/OFF switch. If the unit fails to restart,
call a qualied technician for service.
Δ Ensure the domestic power supply is checked
by a qualied electrician to ensure that it can
support the maximum power absorption of the
appliance, as indicated on the rating plate.
In particular, make sure that the cable sizes
are adequate for the power absorbed by the
appliance;
Δ The power supply cable must be replaced by a
qualied electrician. If the cable is damaged in
any way, switch off the appliance and have the
cable replaced by a suitably qualied electrician;
Δ When using an electrical appliance, a few
fundamental rules must be observed:
Δ DO NOT touch the appliance with damp or wet
parts of the body or when barefoot.
Δ DO NOT pull on the electric wires.
Δ DO NOT allow the appliance to be used by
children or anyone unfamiliar with its operation.
