ambient temperatures ranging from 5~35°C.
▪ Mind the following spacing installation guidelines:
>10 >10
(mm)

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
10 litre for EHVH/X04+08 and 20 litre for EHVH/X11+16, the internal
water volume of the indoor unit NOT included.
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.
