▪ Water leakage. Take care that in the event of a water leak, water CANNOT cause
any damage to the installation space and its surroundings.
▪ Noise. Choose a location where the operation noise of the unit does not disturb
the room occupants. To avoid that the refrigerant noise disturbs the people in
the room, keep at least 5 m of piping between the occupied room and the BS
unit. If there is no false ceiling in the room, it is advised to add sound insulation
around the piping between the BS unit and the indoor unit, or to keep more
length between the BS unit and the indoor unit.

diameter).

piping, install a trap.
