6.17 - Electrical connections: general
information
WARNING !!! The electrical safety of the appliance
is achieved only when it is properly connected to an
effective grounding system, performed as required by
current safety standards.
It is necessary to verify this fundamental safety requirement.
If in doubt, request an accurate check of the electrical system
by a professionally qualified technician.

Have a professionally qualified technician check that the
electrical system is adequate for the electrical power,
indicated on the plate, required by the appliance.

The connection of the appliance to the main electrical
supply must be carried out with a connection with a mobile
plug. The use of adapters, multiple sockets, extensions,
etc. is not allowed.

The connection of the appliance to the main electrical
supply must be carried out with a three-pole, double-
insulated electric cable with a section suitable for the
electrical absorption of the machine (section 11).

For connection to the electrical network, a bipolar switch
with a contact opening distance of at least 3mm as required
by current regulations must be provided in the vicinity of
the appliance.

Respect the polarity between phase and neutral when
connecting the appliance.

Make sure that the pipes of the water and heating systems
are not used as earth sockets for the electrical or telephone
system. These pipes are absolutely not suitable for this
purpose, furthermore serious corrosion damage to the
appliance, pipes and radiators could occur in a short time.
WARNING !!! This appliance has no protection
against the effects caused by lightning.
WARNING !!! The product is equipped with
devices controlled via low voltage communication BUS
(for example heat pump BUS, outdoor sensor, remote
control BUS etc.), whose connections must be protected
from electromagnetic disturbances. To avoid faults
or malfunctions and to obtain correct operation of all
devices, the high voltage cables (power cables) and low
voltage cables must have separate paths and not close
together. In case of proximity, the low voltage cables
must be shielded or screened / twisted and suitable for
the type of installation, remembering to connect ONLY
the shielding of one end of the cable to earth.
The electrical connections are positioned inside the indoor
unit as in Figures 3-1, 6-22 and 6-24 and positioned inside
the outdoor unit as in Figures 3-2, 3-3 and 6-24.
6 - INSTALLATION
6.16.4 - Refrigerant addition according to
the length of the refrigerant circuit
The outdoor unit is equipped with an initial pre-charge that
guarantees operation up to a distance of 5 m. If the length
of the refrigerant connection pipes exceeds this value, it is
necessary to add more fluid in the quantity of 40g for each
meter exceeding 5m (see table in Figure 6-21).
WARNING!!! The maximum recommended length
of the refrigerant line between the indoor and outdoor
module is 15m.
Length pipe line (m) Refrigerant quantity
1 Standard pre-charge
2 Standard pre-charge
3 Standard pre-charge
4 Standard pre-charge
5 Standard pre-charge
6 Add 40 grams
7 Add 80 grams
8 Add 120 grams
9 Add 160 grams
10 Add 200 grams
