GENERAL WARNINGS
• The unit and its accessories must only be installed and wired by professionals
with the necessary technical qualifications in installation, conversion,
extension and maintenance of the systems and who are trained to perform
operational and safety checks on these systems. In this manual, these will
generally be referred to as "Personnel with specific technical skills".
• This air conditioner must be installed according to national plant engineering
regulations. Particular attention must be paid to safety guidelines and to
ensuring that the wiring is correctly connected: incorrect wiring connection
could result in supply cables, plug or power socket overheating, which could
present a fire risk.
• Ensure that the air conditioner is connected to the power supply or to a
power socket with the correct voltage and frequency. Using power supplies
with the incorrect voltage and frequency could damage the unit and
consequently risk starting a fire. The voltage must be stable, without major
fluctuations.
• Install on a solid surface which can bear the weight of the air conditioner.
Check the support is securely installed and the unit is absolutely stable after
operating for a long time.
• To protect the unit against short circuits, fit a thermomagnetic isolator switch
to the power line (dedicated to each indoor unit) with a minimum contact
gap of 3mm on all poles.
• The isolator switch and any plug must be installed in an easily accessible
position.
• To ensure good drainage, the condensate discharge pipes must be correctly
installed, following the installation instructions. Adopt the most suitable
measures to avoid heat dispersion and the consequent formation of
condensate. Incorrect installation of the pipes can result in water leaks,
wetting furniture and other items in the room.
• Do not install the unit in a location where it could be affected by inflammable
gas leaks or deposits of materials which are inflammable, explosive,
poisonous, corrosive or hazardous substances. Do not use naked flames near
the units. Risk of fire or explosion. Install the unit in a location with minimal
levels of dust, fumes, humidity and corrosive agents in the air.
• Do not install in laundries.
• When installing the unit, allow sufficient technical clearance around the unit
for maintenance.
• When installing the unit, ensure that the dimensions and weight of the unit
are visible. Respect the dimensions stipulated in this manual with regards to
the refrigerant line length, the height difference between the units, and the
siphons to install along the refrigerant lines.
• For the outdoor unit, choose a location where the noise and air jets will not
disturb the neighbours.
• For the outdoor unit, choose a location which will not disturb the flow of
pedestrians and which is in accordance with local architectural regulations.
• Avoid obstructing the air flow in and out of the indoor and outdoor units.
• Do not make any modifications to the unit! Do not attempt to repair the
unit alone, this is extremely dangerous! Incorrect operations could cause
electric shocks, water leaks, fires etc. Contact your After Sales Service, these
operations must only be carried out by "Personnel with the specific technical
skills".
• Ensure that the power supply and the installed output are adequately scaled
to supply the air conditioner correctly.
• Before operating the air conditioner, ensure that the electric cables,
condensate discharge pipes and cooling connections have been correctly
installed to avoid the risk of water leaks, refrigerant gas leaks and electric
shocks.
• The air conditioner must be correctly earthed. Do not connect the earth
cable to the gas or water pipes, to the lightning conductor, or to the earth
cable of the telephone. Incorrect earthling/grounding could cause electric
shocks.
• Do not handle the air conditioner or touch the keys with wet hands. Risk of
electric shocks.
• The unit and the isolator switch must be turned off before carrying out
maintenance work or cleaning. The rotation of the fans inside the unit can
cause injury.
• Check that the power supply is disconnected before carrying out any
operations on the unit.
• Do not place objects on the outdoor unit and do not climb on top of it.
• For the power supply, use undamaged cables with a section that is suitable
for the load.
• Stranded cables can be used only with a cable terminal. Ensure the strands of
the wires are inserted well.
• Take care when stretching the supply and connection cables around the
units: the cables must not be subject to mechanical stress. The cables must
be protected.
• Do not make connections on the power supply cable: use a longer cable.
Junctions can cause overheating and/or fires.
• If the power cable is damaged, it can be replaced by the manufacturer or by
the technical assistance service or a person with a similar qualification, so as
to prevent any risks.
• Do not leave any cables in direct contact with the refrigerant pipes as they
could reach high temperatures and moving parts, such as the fans.
• If the units are installed in a location exposed to electromagnetic
interference, shielded twisted pair cables must be used for the
communication connections between the units.

• To avoid communication errors between the units, ensure that the
communication line cables are correctly connected to their respective
terminals.
• Periodically check that the installation conditions of the unit have not been
altered: have the system checked by "Personnel with specific technical skills".
• Install the indoor unit and the remote control at least 1 metre away from
electrical appliances, TV, radio, and stereo equipment etc.
• After completing the electrical wirings, carry out a test. This operation must
only be carried out by "Personnel with specific technical skills".
• Once started, the air conditioner must not be switched off for at least 5
minutes to prevent the return of oil to the compressor.
• The wiring diagrams are subject to a continuous update. Therefore, it is
mandatory to refer to those on the machine.
• Only replace the fuses with others identical to the original ones.
• Allow a minimum distance of 1.5 metres between the units and any
inflammable surfaces.
• This appliance can be used by children aged from 8 years and above and
persons with reduced physical, sensory or mental capabilities or lack of
experience and necessary knowledge if they are supervised or have received
instructions concerning use of the appliance in a safe way and understand
the hazards involved. Children should not play with the appliance. Cleaning
and maintenance intended to be performed by the user should not be
performed by children without supervision.
• Do not dismantle or repair the unit while it is in operation.
• Do not obstruct the air flow in and out of the indoor and outdoor units. A
reduction in the air flow reduces the effectiveness of the air conditioner, and
causes breakdowns and malfunctions.
• Do not spray or throw water directly onto the unit. Water may cause electric
shocks or damage to the unit.
• Do not drop the remote control and do not press the keys with pointed
objects: this could damage the remote control.
• Do not pull or deform the supply cable. If the cable is pulled or used
inappropriately, the unit could be damaged and there is a risk of electric
shock.
• Adjust the room temperature correctly to obtain a comfortable environment.
• Switch off the power supply if the air conditioner is not to be used for a long
time. When the power supply switch is turned on, electricity is consumed
even if the system is not operating.
• Do not leave the doors or windows open for long periods when the air
conditioner is operating. The yield in Heating or Cooling mode is reduced if
doors or windows are kept open.
• Position devices such as TV, radio, stereo, etc. at a distance of at least 1 metre
from the indoor unit and the remote control. There may be some audio and
video interference.
• If there is a power cut, when the power is restored the air conditioner will
restart with the settings previously stored in the memory.
• Only use the remote control to adjust the air flow; do not force the fins into
position with your hands.
• Do not direct the air jet straight at your body. Avoid heating or cooling the air
excessively. This may cause health problems.
• Do not direct the air flow straight at animals and plants.
• Do not remove the protection grilles. Do not insert your hands, or any
objects, into the sockets or air vents.
• In the event of issues with the air conditioner (e.g. burning smell), turn off the
air conditioner and disconnect it from the power supply using the isolator
switch. If the anomaly persists, the unit could be damaged and could cause
electric shocks or fires. Contact your local After Sales Service.
• Do not use sprays or insecticides on the unit: risk of fire.
• Air the room. We recommend that the room where the air conditioner is
installed is periodically aired, especially if many people occupy the room or if
there is equipment that uses gas. Insufficient ventilation may result in a lack
of oxygen.
• If the air conditioner is being used in a room where there are children, elderly
or disabled people or bedridden patients, ensure that the room temperature
is appropriate.
• Do not use the air conditioner to store food or to dry clothes.
• If the relative humidity is above 80% (with the doors and windows open) and
the air conditioner has been operating in Cooling or Dehumidification mode
for a long time, condensate water will probably form on the outlet of the
indoor unit. This could cause unwanted dripping.
• Do not under any circumstances insert your fingers or any object into the
unit.
• Do not use the main switch or the plug to switch the air conditioner on or off.
Use the remote control to turn the air conditioner on and off.
• When operating in Cooling mode, the temperature selected must not be
more than 5°C below the outdoor temperature, for optimum comfort and
energy saving.
• When heating, select a moderate temperature.
• Limit the room's exposure to direct sunlight using blinds or by leaving the
windows ajar.
• Do not place hot devices, flames or other heat sources near the unit. The
effectiveness of the air conditioner is reduced, and energy is wasted.
• Clean the air filters once a fortnight.
