7.1.3 To check the water volume and flow rate
The indoor unit has an expansion vessel of 10litre with a factory-set pre-pressure
of 1bar.
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 20 litres, the
internal water volume of the outdoor 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.

Maximum water volume
NOTICE
The maximum water volume depends on whether glycol is added to the water
circuit. For more information on the addition of glycol, refer to "7.2.5To protect the
water circuit against freezing"[485].
Use the following graph to determine the maximum water volume for the
calculated pre-pressure.
