6.13 - Distances between indoor and
outdoor unit
WARNING !!! To ensure proper operation of
the heat pump, respect the minimum and maximum
connection lengths between the hydraulic module and
the outdoor unit (Figure 6-10).
WARNING !!! If the refrigerant connection between
the outdoor unit and the indoor module is less than 2 m,
the following problems may occur:
• functional disturbances due to fluid overload;
• acoustic disturbances due to the circulation of the
refrigerant.
Therefore, provide for a refrigerant connection of at least 2 m,
making one or two horizontal rings to limit these disturbances.

Curves
max number of curves: 15
radius of the curves: between 100mm and 150mm
D
Siphon on the refrigerant gas line
the curves of each siphon affect the maximum number of
curves that can be created on the system. One siphon = 2
curves.
