In regions with snowfall, snow might build up and freeze between the
heat exchanger and the external plate. This might decrease the
operating efficiency. To prevent this:

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).

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.
