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

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

Deciding on where to install the outdoor unit
Outdoor Unit
The outdoor unit must not 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 pipes and cables to be easily connected
to the indoor unit.
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 open
area.
If the outdoor unit is installed at a height, ensure that its base is firmly fixed
in position.
Make sure that the water dripping from the drain hose runs away correctly
and safely.
You have just purchased a system air conditioner and it has been
installed by your installation specialist.
This device must be installed according to the national electrical rules.
With an outdoor unit having net weight upper then 60kg, we suggest do
not install it suspended on wall, but considering floor standing one.
