2 Remove the burrs, and paint the edges and areas around the
edges using repair paint to prevent rusting.
4.2.4 To prevent the outdoor unit from falling
over
In case the unit is installed in places where strong wind can tilt the
unit, take following measure:
1 Prepare 2 cables as indicated in the following illustration (field
supply).
2 Place the 2 cables over the outdoor unit.
3 Insert a rubber sheet between the cables and the outdoor unit
to prevent the cables from scratching the paint (field supply).
4 Attach the ends of the cables and tighten them.

Connecting the water piping

4.3.1

To connect the water piping

NOTICE
Do NOT use excessive force when connecting the piping.
Deformation of the piping can cause malfunctioning of the
unit. Make sure that the tightening torque does NOT
exceed 30 N•m.
To facilitate service and maintenance, 2 shut-off valves are provided.
Mount the valves on the space heating water inlet and space heating
water outlet. Mind their position: the integrated drain valves will only
drain the side of the circuit on which they are located. To be able to
only drain the unit, make sure the drain valves are positioned
between the shut‑off valves and the unit.

see the installation manual of the domestic hot water tank.
NOTICE
Install a manometer in the system.
NOTICE
Install air purge valves at all local high points.
NOTICE
In case an optional domestic hot water tank is installed: A
pressure relief valve (field supply) with an opening
pressure of maximum 10 bar must be installed on the
domestic cold water inlet connection in accordance with
the applicable legislation.
4.3.2 To protect the water circuit against
freezing
Frost can damage the system. To prevent the hydraulic components
from freezing, the software is equipped with special frost protection
functions, that include the activation of pump, internal heaters, and/
or backup heater operation in case of low temperatures.
However, in case of a power failure, these functions cannot
guarantee protection. It is therefore recommended to add glycol to
the water circuit. The required concentration depends on the lowest
expected outdoor temperature, and on whether you want to protect
the system from bursting or from freezing. To prevent the system
from freezing, more glycol is required. Add glycol according to the
table below.
INFORMATION
▪ Protection against bursting: the glycol will prevent the
piping from bursting, but NOT the liquid inside the
piping from freezing.
▪ Protection against freezing: the glycol will prevent the
liquid inside the piping from freezing.
