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 qualified personnel.
• Verify that the air conditioner is not installed in an easily accessible area.
General information
Carefully 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.
For maximum safety, installers should always carefully read the following warnings.
Store 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.
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 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.
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 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.
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.
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, scaffolding or any other means of elevation won’t be
considered in-warranty and charged to end user.
Power suPPly line, fuse or circuit breaker
Always make sure that the power supply is compliant with current safety standards. Always install the air conditioner in compliance
with current local safety standards.
Always verify that a suitable grounding connection is available.
Verify that the voltage and frequency of the power supply comply with the specifications and that the installed power is sufficient
to ensure the operation of any other domestic appliance connected to the same electric lines.
Always verify that the cut-off and protection switches are suitably dimensioned.
Verify that the air conditioner is connected to the power supply in accordance with the instructions provided in the wiring
diagram included in the manual.
Always verify that electric connections (cable entry, section of leads, protections…) are compliant with the electric specifications
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.

Place the pattern sheet on the ceiling at the spot where you want to
install the indoor unit.
Since the diagram is made of paper, it may shrink or stretch
slightly due to temperature or humidity. For this reason,
before drilling the holes maintain the correct dimensions
between the markings.
Note
2
Insert bolt anchors, use existing ceiling supports or construct a suitable
support as shown in figure.
3
Install the suspension bolts depending on the ceiling type.
Ensure that the ceiling is strong enough to support
the weight of the indoor unit. Before hanging the unit,
test the strength of each attached suspension bolt.
If the length of suspension bolt is more than 1.5m (4.92 ft),
it is required to prevent vibration.
If this is not possible, create an opening on the false ceiling
in order to be able to use it to perform the required operations
on the indoor unit.
