Safety Precautions
Carefully follow the precautions listed below because they are essential to guarantee the safety of the equipment.
WARNING
• Always disconnect the air conditioner from the power supply before servicing it
or accessing its internal components.
• Verify that installation and testing operations are performed by qualied
personnel.
• Verify that the air conditioner is not installed in an easily accessible area.
General information
XCarefully read the content of this manual before installing the air conditioner and store the manual in a safe place
in order to be able to use it as reference after installation.
XFor maximum safety, installers should always carefully read the following warnings.
XStore the operation and installation manual in a safe location and remember to hand it over to the new owner if
the air conditioner is sold or transferred.
XThis manual explains how to install an indoor unit with a split system with two SAMSUNG units. The use of other
types of units with dierent 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.
XThe manufacturer shall not be responsible for damage originating from unauthorized changes or the improper
connection of electric and hydraulic lines. Failure to comply with these instructions or to comply with the
requirements set forth in the “Operating limits”table, included in the manual, shall immediately invalidate the
warranty.
XThe 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.
XDo not use the units if damaged. If problems occur, switch the unit o and disconnect it from the power supply.
XIn order to prevent electric shocks, res 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.
XAlways remember to inspect the unit, electric connections, refrigerant tubes and protections regularly. These
operations should be performed by qualied personnel only.
XThe unit contains moving parts, which should always be kept out of the reach of children.
XDo not attempt to repair, move, alter or reinstall the unit. If performed by unauthorized personnel, these operations
may cause electric shocks or res.
XDo not place containers with liquids or other objects on the unit.
XAll the materials used for the manufacture and packaging of the air conditioner are recyclable.
XThe packing material and exhaust batteries of the remote control(optional) must be disposed of in accordance with
current laws.
XThe 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.

Safety Precautions
Installing the unit
IMPORTANT: When installing the unit, always remember to connect rst the refrigerant tubes, then the electrical lines.
Always disassemble the electric lines before the refrigerant tubes.
XUpon 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.)
XAfter completing the installation, always carry out a functional test and provide the instructions on how to operate
the air conditioner to the user.
XDo not use the air conditioner in environments with hazardous substances or close to equipment that release free
ames to avoid the occurrence of res, explosions or injuries.
XThe 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.
XOur 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, scaolding or any other
means of elevation won’t be considered in-warranty and charged to end user.
Power supply line, fuse or circuit breaker
XAlways make sure that the power supply is compliant with current safety standards. Always install the air
conditioner in compliance with current local safety standards.
XAlways verify that a suitable grounding connection is available.
XVerify that the voltage and frequency of the power supply comply with the specications and that the installed
power is sucient to ensure the operation of any other domestic appliance connected to the same electric lines.
XAlways verify that the cut-o and protection switches are suitably dimensioned.
XVerify that the air conditioner is connected to the power supply in accordance with the instructions provided in the
wiring diagram included in the manual.
XAlways verify that electric connections (cable entry, section of leads, protections…) are compliant with the electric
specications and with the instructions provided in the wiring scheme. Always verify that all connections comply
with the standards applicable to the installation of air conditioners.
XBe sure not to perform power cable modication, extension wiring, and multiple wire connection.
- It may cause electric shock or re due to poor connection, poor insulation, or current limit override.
- When extension wiring is required due to power line damage, refer to “How to connect your extended power
cables”in the installation manual.

ENGLISH
• Make sure that you earth the cables.
- Do not connect the earth wire to the gas pipe, water pipe, lighting rod or telephone wire.
If earthing is not complete, electric shock or re may occur.
• Install the circuit breaker.
- If the circuit breaker is not installed, electric shock or re may occur.
• Make sure that the condensed water dripping from the drain hose runs out properly and safely.
• Install the power cable and communication cable of the indoor and outdoor unit at least 1m away from
the electric appliance.
• Install the indoor unit away from lighting apparatus using the ballast.
- If you use the wireless remote control, reception error may occur due to the ballast of the lighting
apparatus.
• Do not install the air conditioner in following places.
- Place where there is mineral oil or arsenic acid. Resin parts ame and the accessories may drop or
water may leak. The capacity of the heat exchanger may reduce or the air conditioner may be out
of order.
- The place where corrosive gas such as sulfurous acid gas generates from the vent pipe or air outlet.
The copper pipe or connection pipe may corrode and refrigerant may leak.
- The place where there is a machine that generates electromagnetic waves. The air conditioner may
not operate normally due to control system.
