must be disposed of in authorized centers or returned to the retailer so that it can be disposed of correctly and safely.
X The appliance is not intended for use by persons (including children) with reduced physical, sensory or mental capabilities, or lack
of experience and knowledge, unless they have been given supervision or instruction concerning use of the appliance by a person
responsible for their safety: Young children should be supervised to ensure that they do not play with the appliance.
INSTALLING THE UNIT
IMPORTANT:
X Upon receipt, inspect the product to verify that it has not been damaged during transport. If the product appears damaged,
DO NOT INSTALL it and immediately report the damage to the carrier or retailer (if the installer or the authorized technician has
collected the material from the retailer.)
X After completing the installation, always carry out a functional test and provide the instructions on how to operate the air
conditioner to the user.
X Do not use the air conditioner in environments with hazardous substances or close to equipment that release free flames to avoid
the occurrence of fires, explosions or injuries.
X To prevent injury when accidentally touching the indoor unit fan, install the indoor unit at least 2.5m above the floor.
X The air conditioner should be used only for the applications for which it has been designed: the indoor unit is not suitable to be
installed in areas used for laundry.
X Our units must be installed in compliance with the spaces indicated in the installation manual to ensure either accessibility from
both sides or ability to perform routine maintenance and repairs. The units’ components must be accessible and that can be
disassembled in conditions of complete safety either for people or things. For this reason, where it is not observed as indicated into
the Installation Manual, the cost necessary to reach and repair the unit (in safety, as required by current regulations in force) with
slings, trucks, scaffolding or any other means of elevation won’t be considered in-warranty and charged to end user.
When installing the unit, always remember to connect first the refrigerant tubes, then the electrical lines.
Always disassemble the electric lines before the refrigerant tubes.

Deciding on Where to Install the Air Conditioner
When deciding on the location of the air conditioner with the owner, the following restrictions must be
taken into account.
General
Do NOT install the air conditioner in a location where it will come into contact with the following elements:
◆ Combustible gases
◆ Saline air
◆ Machine oil
◆ Sulphide gas
◆ Special environmental conditions
◆ The air conditioner should be used only for the applications for which it has been designed : the indoor unit is not
suit able to be installed in areas used for laundry. If you must install the unit in such conditions, first consult your dealer.
Outdoor Unit
◆ The outdoor unit must NEVER be placed on its side or upside down, as the compressor lubrication oil will run into the
cooling circuit and seriously damage the unit.
◆ Choose a location that is dry and sunny, but not exposed to direct sunlight or strong winds.
◆ Do not block any passageways or thoroughfares.
◆ Choose a location where the noise of the air conditioner when running and the discharged air do not disturb any
neighbours.
◆ Choose a position that enables the piping and cables to be easily connected to the indoor unit and the recommended
length will be respected.
◆ Install the outdoor unit on a flat, stable surface that can support its weight and does not generate any unnecessary
noise and vibration.
◆ Position the outdoor unit so that the air flow is directed towards the outside, as indicated by the arrows on the top of the
unit.
◆ Maintain sufficient clearance around the outdoor unit, as indicated in the diagram on the page opposite.
◆ Make sure that the water dripping from the drain hose runs away correctly and safely.
X When installing the outdoor unit near seashore, make sure it is not directly exposed to sea breeze. If you can not nd a
adequate place without direct see breeze, protection wall should be constructed.
