owner if the air conditioner is sold or transferred.

 

This manual explains how to install an indoor unit with 

a split system with two SAMSUNG units. The use of 

other types of units with different control systems may 

damage the units and invalidate the warranty. The 

manufacturer shall not be responsible for damages 

arising from the use of non compliant units.

 

The manufacturer shall not be responsible for damage 

originating from unauthorized changes or the 

improper connection of electric and requirements set 

forth in the “Operating limits” table, included in the 

manual, shall immediately invalidate the warranty.

 

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.

 

Do not use the units if damaged. If problems occur, 

switch the unit off and disconnect it from the power 

supply.

 

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 controller(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 centres or returned to the retailer so that it 

can be disposed of correctly and safely.

 

This 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. Children should be 

supervised to ensure that they do not play with the 

appliance.
