4.3 Hydraulic connection of the device
Connect the external unit to the heating system with water pipes of appropriate dimensions (see
technical data - chapter 7). The pipes have to be insulated with insulation which is at least 13 mm thick
and resistant to weather-proof. The hydraulic connection of the system is made via a transitional pipe
connection on the device.
CAUTION
The water pipes must not be installed alongside the heating in the screed or alongside any
kind of source of heat or cold.
External pipe connection
The pipe connection between the DHW room and the device can be made using two ribbed pipes (A)
or one separate ribbed pipe (B).

For unobstructed and safe operation it is important to have a heat accumulator. The accumulator is
needed for the hydraulic balancing, ensuring unobstructed flow and defrosting and a longer lifespan of
the device. A larger accumulator ensures a more even temperature of heating and more comfort. The
accumulator is dimensioned to provide at least 10 litres per kW of heating power under the condition of
A2W35.
WARNING
Before connecting the device, it is necessary to rinse the pipe system thoroughly and
remove impurities (hard particles, oils, greases ...).
CAUTION
The closing valve with exhaust has to be installed lower than the pipe connections on the
device.
4.4 Heating system of machine installations
WARNING
The dimensioning of circulation pumps, valves, safety elements and pipes has to be
performed by the designing engineer according to the heating/cooling capacity of the
device.
