Safety instructions
These instructions are intended exclusively for authorised profes-
sionals. To avoid accidents and damage due to incorrect operation,
carefully read through these operating instructions before you start
working with the freshwater station. If you carry out any alterations to
the construction of the freshwater station or the safety devices, you
may invalidate your right to make guarantee claims. Always observe
the local regulations.
Intended use
The freshwater station may only be installed in heating systems between the buffer tank and
the drinking water circuit. The technical limit values specified in this manual must be consid-
ered.
Incorrect use will result in the negation of any liability claims.
Electrical connection
Any electrical connections must be made by qualified electricians. Connection cables must
be routed in the recesses provided in the insulated base in such a way that direct contact
with the pump casing and the pipes is prevented.
Before switching on, check whether the supply voltage matches that stated on the power rat-
ing plates of the pump and the controller. All connections must correspond to the local regu-
lations.
Safety standards during installation, commissioning and maintenance
Installation, commissioning and maintenance may only be carried out by qualified persons
who are familiar with these operating instructions.
Before you start work on the system, ensure that the system is switched off and all compo-
nents are cooled down. When replacing the pump, turn the 4 ball valves into the closed posi-
tion.
In multi-occupancy dwellings, legionella protection must be observed in accordance with the
local regulations.
WARNING!
Dependent on the pump and system operating conditions, the sur-
face temperatures can be very high. Direct contact with the pump or pipes can
result in burns!
Important note:
The secondary flow rate (cold / hot water)
must never be more than 40 l/min!
