• The air conditioner must be appropriately 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. A bad earthing may result in electric shocks.
• 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 unit and the unipolar switch must be turned off before carrying out maintenance work or cleaning. The rotation of
the fans inside the unit may cause injuries.
• Ensure that the power supply has been disconnected before carrying out any intervention.
• Do not install the air conditioner in places exposed to corrosiveagents.
• Do not place any objects onto the outdoor unit and do not climb onto it. This may cause objects or persons to fall
with a risk of injury.
• Once the electrical connections have been made, they must be tested. This operation may only be performed by
“Personnel with specific technical skills”.
• If the supply cable is damaged, it must be replaced to avoid danger. The supply cable must only be replaced with a
cable of the type stipulated in the manual. This operation can be performed only by “Qualified Personnel”.
• To protect the unit against short circuits, mount on the supply line a unipolar magnet-circuit breaker with a minimum
contact separation of at least 3mm in all poles.
• This air conditioner must be installed according to national plant engineering regulations Pay special attention to all
the aspects pertaining to safety and make sure that the cables are connected properly. An improper connection may
result in power cord, plug and socket overheating, with a serious risk of fire as a consequence.
• Do not leave any cable in direct contact with the refrigerant pipes and with the moving parts, such as fans, as they
could reach high temperatures.
• Replace fuses only with identical ones to the original.
7. IMPORTANT INFORMATION TO USERS
• 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 knowledge if they have been given supervision or instruction concerning
use of the appliance in a safe way and understand the hazards involved. Children shall not play the appliance.
Cleaning and user maintenance shall not be made by children without supervision.
• 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.
• Do not pull or twist the power supply cable. If the cable is pulled or used inappropriately, the unit may be damaged or
cause electric shocks.
• To avoid communication errors between the units, ensure that the communication line cables are correctly
connected to their respective terminals.
• Adjust the 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.
Disconnect the power supply to the air conditioner to save energy.
• 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.
