• Connect a rubber hose (not supplied) to the fitting (6) if water is drained from the outdoor unit in heating
mode.

e. If the outdoor unit is higher than the indoor units, to prevent rain entering, a downward bow must be made
along the connection pipe (siphon) before the connection pipe enters the wall. This is to guarantee that
the lowest point of the connection pipe is outdoors.
2.6.3 - Execution, installation and connection of the refrigeration lines
Do not make the connections using normal hydraulic piping, which could contain
scrap residues, dirt or water, and which can damage the unit components and
jeopardise correct operation of the appliance.
