DAMAGE TO THE WATER HEATER AND THE ENVIRON-
MENT:
The water heater must be installed by a licensed elec-
trician and plumber. The installation must comply with
all national, state and local plumbing and electric codes.
Service of the water heater must be performed by qual-
ified service technicians.
!
DAMAGE TO THE WATER HEATER AND THE ENVIRON-
MENT:
Supply this appliance only from a grounded system. A
green terminal (or a wire connector marked “G”, “GR”,
“GROUND”, OR “GROUNDING”) is provided for wiring the
appliance. To reduce the risk of electric shock, connect
this terminal or connector to the grounding terminal of
the electric service or supply panel with a continuous
copper wire in accordance with the electrical installa-
tion code.
Note
When mounting the water heater to the wall, countersunk
screws must be used in order to maintain the IP 24 rating.
See section 9.1.4, “Mounting the water heater”, pg. 10.

WARNING
Injury
The water heater may be used by children aged 3 and
older and persons with reduced physical, sensory or
mental capabilities or a lack of experience and know-
how, provided that they are supervised or they have
been instructed on how to use the water heater safely
and have understood the potential risks. Children must
never play with the water heater. Children must never
clean the water heater or perform user maintenance un-
less they are supervised.
Where children or persons with limited physical, sensory or men-
tal abilities are allowed to use this water heater, we recommend
asking the qualified contractor to set a permanent “Internal an-
ti-scalding protection” temperature limit.

3. Water heater description
The water heater switches on automatically as soon as you open
the hot water valve at the tap. When you close the tap, the water
heater switches off automatically. The unit heats water as it flows
through.
From the activation flow rate, the control unit regulates the cor-
rect heating output, subject to the temperature selected and the
current cold water temperature. The DHW outlet temperature can
be variably adjusted.
The electronically controlled tankless water heater maintains a
consistent outlet temperature. This is irrespective of the inlet tem-
perature, up to the maximum output of the water heater.
If the water heater is operated with preheated water and the inlet
temperature exceeds the chosen set temperature, the water is not
heated further.
DHW temperature
The DHW outlet temperature can be variably adjusted, with a
range from 68–140 °F (20–60 °C).
Heating system
The Direct Coil
™
heating system is comprised of a pressure-tested,
glass-reinforced polyamide heating chamber with a nichrome wire
direct heating coil. It is suitable for hard and soft water areas and
is largely insusceptible to scale build-up. The Direct Coil
™
heating
system ensures rapid, accurate, and efficient DHW production.
