The indoor unit has an expansion vessel of 10litre with a factory set pre-pressure
of 1bar.
To make sure that the unit operates properly:
You must check the minimum and maximum water volume.
You might need to adjust the pre-pressure of the expansion vessel.
Minimum water volume
Check that the total water volume in the installation is minimum 13.5 litre, the
internal water volume of the indoor unit NOT included.
INFORMATION
In critical processes, or in rooms with a high heat load, extra water might be
required.
NOTICE
When circulation in each space heating/cooling 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.
