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.
Onlyusecopperpiping, specic forrefrigeration,whichissupplied clean and
sealed at the ends.
When the cuts have been made, seal the end of the roll and piece cut immediately.
Pre-insulated copper pipes can be used for refrigeration.
Onlyusepipeswithdiametersthatreectthedimensionsdescribedinthe“Technicaldata”paragraph.
Identify the route of the piping in a way to reduce the length and bends as much as possible in order to obtain
maximum system performance.

The refrigerant should be charge from the service port on the outdoor unit’s low
pressure valve.
Piping connections must be outdoors.
a. Fasten a cable raceway to the wall (possibly with internal partitioning) of suitable size for the pipes and
electric wires to pass through.
b. Cut the sections of pipe leaving an extra 3÷4 cm on the ends.
