the floor to the flare nut.
▪ The indoor unit is designed for indoor installation only (in a
technical room or similar) and for ambient temperatures ranging
5~30°C in heating mode.
3.2
Preparing water 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
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.
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 or operation).
See the installer reference guide for more information.
