1 Safety
1.1 Action-related warnings
Classification of action-related warnings
The action-related warnings are classified in
accordance with the severity of the possible
danger using the following warning signs and
signal words:
Warning symbols and signal words
Danger!
Imminent danger to life or risk of
severe personal injury
Danger!
Risk of death from electric shock
Warning.
Risk of minor personal injury
Caution.
Risk of material or environmental
damage
1.2 Intended use
There is a risk of injury or death to the user or
others, or of damage to the product and other
property in the event of improper use or use
for which it is not intended.
Vaillant electronicVED electric instantaneous water heaters must only be used to heat
up drinking water.
Vaillant electronicVED electric instantaneous water heaters are suitable for use only
in an enclosed, frost-free room in a domestic
environment.
Vaillant electronicVED electric instantaneous water heaters are not suitable for operation in secondary circulation lines.
Intended use includes the following:
– observance of accompanying operating,
installation and servicing instructions for
the product and any other system components
– installing and fitting the product in accord-
ance with the product and system approval
– compliance with all inspection and main-
tenance conditions listed in the instructions.
Intended use also covers installation in accordance with the IP code.
Any other use that is not specified in these
instructions, or use beyond that specified in
this document shall be considered improper
use. Any direct commercial or industrial use
is also deemed to be improper.
Caution.
Improper use of any kind is prohibited.
1.3 General safety information
1.3.1 Risk caused by inadequate
qualifications
The following work must only be carried out
by competent persons who are sufficiently
qualified to do so:
– Set-up
– Dismantling
– Installation
– Start-up
– Inspection and maintenance
– Repair
– Decommissioning
▶ Observe all instructions that are included
with the product.
▶ Proceed in accordance with current tech-
nology.
▶ Observe all applicable directives, stand-
ards, laws and other regulations.
1.3.2 Risk of material damage caused by
frost
▶ Do not install the product in rooms prone
to frost.
1.3.3 Risk of death from electric shock
There is a risk of death from electric shock if
you touch live components.
Before commencing work on the product:
▶ Disconnect the product from the power
supply by switching off all power supplies
at all poles (electrical partition with a contact gap of at least 3 mm, e.g. fuse or circuit breaker).
▶ Secure against being switched back on
again.
▶ Check that there is no voltage.

1.3.4 Risk of death from electric shock
from live lines and connections
The drinking water that is used must demonstrate a specific resistance of ≥ 900 Ω at
15 °C. Otherwise, the product must not be
used.
▶ Before installing the unit, ask your water
company to inform you about the water
resistance and conductivity.
1.3.5 Risk of being scalded by hot water
The outlet temperatures at the draw-off points
can be up to approx. 60 °C.
▶ When using the product, ensure that you
do not scald yourself.
▶ If you want to be protected from scald-
ing, set the maximum temperature of the
product to 43 °C.
1.3.6 Risk of being scalded by hot water
If a solar thermal energy system is connected
upstream, hot water temperatures of over
43 °C could be generated even if the scald
protection function is set.
If a solar thermal energy system is connected
upstream of the product, the inlet temperature must be limited by including precautionary features in the design (e.g. a mixer valve).
▶ Install a mixer valve to limit the inlet tem-
perature to 25 °C.
1.3.7 Risk of being burned or scalded by
hot components
▶ Only carry out work on these components
once they have cooled down.
1.3.8 Risk of material damage caused by
using an unsuitable tool
▶ Use the correct tool to tighten or loosen
threaded connections.
1.4 Regulations (directives, laws,
standards)
▶ Observe the national regulations, stand-
ards, guidelines and laws.

3.2 Function
The product heats up drinking water via a bare wire in the
heating block using the flow-through principle.
The drinking water can be drawn from several draw-off
points.
The electronics measure the temperature of the water in the
cold water supply and the water volume flow. The electrical
performance that is required to heat the water to the required
hot water temperature is calculated using these two values.
The temperature can be set to any value between 30 °C and
60 °C on the product's temperature selector.
The hot water temperature depends on:
– Water inlet temperature
– Water outlet volume
– Performance category of the unit
If the set hot water temperature is not reached, reduce the
water volume.
3.3 Information on the data plate
