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.
Only use copper piping, specific for refrigeration, which is supplied 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.
Only use pipes with diameters that reflect the dimensions described in the "Technical data" 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.
Performance is based on standard length and maximum length allowed.
Oil collectors for 5-7 metres must be installed (figure 17).
The minimum recommended length of the pipes is 3 metres, while the length of
the pipelines covered by preload is equal to 5 metres. Beyond that length it is
necessary to add the quantity of load indicated in the table below.
to establish whether the gas load needs to be topped-up, refer to the table below.

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.
Use a wheel pipe cutter only to cut the pipes (fig. 18) clamping it in short lengths
so as not to crush the pipe.
