Preparation

3.1

Preparing the installation site

WARNING
The appliance shall be stored in a room without
continuously operating ignition sources (example: open
flames, an operating gas appliance or an operating electric
heater).
3.1.1 Installation site requirements of the
indoor unit
▪ The indoor unit is designed for indoor installation only and for the
following ambient temperatures:
▪ Space heating operation: 5~30°C
▪ Space cooling operation: 5~35°C
▪ Domestic hot water production: 5~35°C
▪ The maximum height difference between indoor unit and outdoor
unit is 20 m.
▪ Mind the following spacing installation guidelines:

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.
▪ Valve towards expansion vessel. The valve towards the
expansion vessel (if equipped) MUST be open.
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 20
litres, the internal water volume of the outdoor 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 in the installation is guaranteed in
all conditions. This minimum flow rate is required during defrost/
backup heater operation. For this purpose, use the overpressure
bypass valve delivered with the unit, and respect the minimum water
volume.
NOTICE
To guarantee proper operation it is recommended to have
a minimum flow of 28 l/min during DHW.
NOTICE
If glycol was added to the water circuit, and the
temperature of the water circuit is low, the flow rate will
NOT be displayed on the user interface. In this case, the
minimum flow rate can be checked by way of the pump
test (check that the user interface does NOT display error
7H).
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.
