Preparing piping

NOTICE
In case of plastic pipes, make sure they are fully oxygen
diffusion tight according to DIN 4726. The diffusion of
oxygen into the piping can lead to excessive corrosion.
3.2.1 To check the water volume and flow rate
of the space heating circuit and brine
circuit
Minimum water volume
Check that the total water volume per circuit in the installation is
minimum 20 litre, the internal water volume of the indoor unit NOT
included.
INFORMATION
If a minimum heating load of 1 kW can be guaranteed and
setting [9‑04] is changed by the installer from 1 to 4°C, the
minimum water volume can be lowered to 10 litre.
INFORMATION
In critical processes, or in rooms with a high heat load,
extra water might be required.
NOTICE
When circulation in each space heating loop is controlled
by remotely controlled valves, it is important that the
minimum water volume is guaranteed, even if all of the
valves are closed.
Minimum flow rate
Check that the minimum flow rate (required during defrost/backup
heater operation) in the installation is guaranteed in all conditions.
NOTICE
When circulation in each or certain space heating loops is
controlled by remotely controlled valves, it is important that
the minimum flow rate is guaranteed, even if all valves are
closed. In case the minimum flow rate cannot be reached,
a flow error 7H will be generated (no heating/operation).
See the installer reference guide for more information.
Minimum required flow rate during backup heater operation
12 l/min
See the recommended procedure as described in
during commissioning" on page 20.
