Safety instructions
We have developed this product in accordance with
current safety requirements.
Observe the following instructions for safe use.
2.4.1
Danger to life due to legionella
formation
Ensure the following:
•
The temperature of the potable water in the cold
water riser must not exceed 25 °C.
•
The water in the potable water circuit must be
completely replaced after 72 hours at the latest.
•
When using a circulation pipe, the hot water
temperature must be at least 60 °C. The temperature
difference between the hot water outlet of the heat
exchanger and the return of the circulation pipe at the
station must not exceed 5 °C.
2.4.2 Danger to life due to electric current
f
Make sure that the product can be disconnected from
the power supply at any time.
f
Do not operate the product if there is visible damage.
The controller only needs to be opened when
using accessory components. Work on the pow-
er supply is therefore only necessary when us-
ing accessory components.
Work on the power supply may only be carried out by a
specialist electrician.
f
Disconnect the station from the power supply at all
poles and secure it against being switched on again.
f
Check that no voltage is present.
f
Only install the product in dry indoor areas.

2.4.4 Risk of scalding due to hot water
Due to setting or defect of the controller, the hot water
temperature at the draw-off points can rise up to the
heating water temperature in the buffer storage cylinder.
If there is a risk of scalding in accordance with DIN EN 806
and DIN 1988 due to a high heating water temperature in
the buffer storage cylinder, you must install scald
protections at all draw-off points.
If the heating water temperature in the buffer storage
cylinder is low, resulting in a low hot water temperature
without risk of scalding at the draw-off points, you must
instruct the system operator to ensure the low heating
water temperature in the buffer storage cylinder all year
round.
2.4.5 Risk of injury from pressurised
components
f
Only carry out work on the storage cylinder circuit
or the potable water circuit when the system is
depressurised.
f
Adhere to the permissible operating pressures during
operation.
f
Install a safety valve that cannot be shut off in the
potable water heating system (DIN EN 806-2).
2.4.6 Risk of burns due to unintentionally
escaping hot media
f
Only carry out work on the storage cylinder circuit
or the potable water circuit when the system is
depressurised.
f
Allow the product to cool down before working on it.
f
Check that the product is not leaking after work is
complete.
f
Wear safety goggles.
2.4.7 Risk of burns on hot components and
surfaces
f
Allow the product to cool down before working on it.
f
Wear suitable protective clothing to avoid unprotected
contact with hot fittings and system components.
2.4.8 Risk of injury due to the weight of the
product
f
Always wear safety shoes during installation.
2.4.9 Risk of injury from improper work
Stored energy, angular components, points and corners on
and in the product can cause injuries.
