SAFETY

2. Safety

2.1 Intended use

This appliance is intended for residential use. It can be used safely

by untrained persons. The appliance can also be used in a non-res-

idential environment, e.g. in a small business, as long as it is used

in the same way.

This appliance is suitable for heating domestic hot water (DHW)

or for heating preheated water. The appliance is designed for one

hand-washing sink.

Any other use beyond that described shall be deemed inappropriate.

Observation of these instructions and of instructions for any acces-

sories used is also part of the correct use of this appliance.

2.2 General safety instructions

DANGER: Scalding

During operation, the tap can reach temperatures in excess

of 122°F / 50°C. There is a risk of scalding at outlet temper-

atures in excess of 109°F / 43°C.

DANGER: Electrocution

Any damaged power cables must be replaced by a qual-

iﬁed electrician. This prevents potential hazards due to

improper installation.

Material losses:

Protect the appliance and the tap against freezing.

Material losses:

Only use the provided aerator. Prevent scale build-up at

the tap outlets (See chapter 6, “Cleaning, care and main-

tenance”, pg. 7).

4. Appliance description

This electronically controlled tankless electric water heater main-

tains a constant outlet temperature up to its output limit, regardless

of the inlet temperature.

This appliance has been factory-set to 100°F / 38°C. Once this

temperature has been reached, the main control board automat-

ically maintains this temperature. The output is matched to the set

temperature and prevents this temperature from being exceeded.

The appliance heats the water directly at the draw-off point as soon

as the tap is opened. Short pipe runs ensure that energy and water

losses are minimal.

The DHW output temperature depends on the cold water tempera-

ture, water heater capacity and the ﬂow rate.

The bare wire heating system is suitable for hard and soft water

areas. This heating system has a low susceptibility to scale build-up.

The heating system ensures quick and efﬁcient hot water provided

at the point-of-use.

Your qualiﬁed contractor can adjust the maximum temperature

setting (see 11.4, “Settings”, pg. 13).

You must use the aerator provided with the appliance.

is sufﬁcient for cleaning the outside of the appliance.

f Check the taps/valves regularly. Lime-scale deposits can be

removed using commercially available descaling agents.

f Have the electrical safety of the appliance periodically checked

by an electrician.
