Safety precautions

General information

 In order to prevent electric shocks, fires or injuries, always stop the unit, disable the protection switch and contact

SAMSUNG’s technical support if the unit produces smoke, if the power cable is hot or damaged or if the unit is very noisy.

 Always remember to inspect the unit, electric connections, refrigerant tubes and protections regularly.

These operations should be performed by qualified personnel only.

 The unit contains moving parts, which should always be kept out of the reach of children.  Do not attempt to repair, move, alter or reinstall the unit. If performed by unauthorized personnel, these operations

may cause electric shocks or fires.

 Do not place containers with liquids or other objects on the unit. 

All the materials used for the manufacture and packaging of the air conditioner are recyclable.

 The packing material and exhaust batteries of the remote control(optional) must be disposed of in accordance with

current laws.

 The air conditioner contains a refrigerant that has to be disposed of as special waste. At the end of its life cycle, the air

conditioner must be disposed of in authorized centers or returned to the retailer so that it can be disposed of correctly and safely.

installinG the unit

IMPORTANT: 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.

 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.)

 After completing the installation, always carry out a functional test and provide the instructions on how to operate

the air conditioner to the user.

 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.

 To prevent injury when accidentally touching the indoor unit fan, install the indoor unit at least 2.5m above the floor.  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.

 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.

◆ 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.

◆ 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.

◆ You have just purchased a Free Joint Multi air conditioner and it has been installed by your installation specialist.

◆ This device must be installed according to the national electrical rules.

◆ Max input power & current is measured according to IEC standard and input power & current is measured according to ISO standard.

◆ More than 2 indoor units should be installed when you use Free Joint Multi air conditioner.

◆ Our units must be installed in compliance with the spaces indicated in the installation manual to ensure either

◆ With an outdoor unit having net weight upper then 60kg,we suggest do not install it suspended on wall, but considering floor standing one.
