
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 air conditioner is compliant with the requirements of the Low Voltage Directive (72/23/EEC),
the EMC Directive (89/336/EEC) and the Directive on pressurized equipment (97/23/EEC).

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.

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 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.

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.
