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 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 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.

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.



In damp areas or locations where it could come into contact with water.
(for example rooms used for laundry)



In areas where curtains and furniture could affect the supply and discharge of air.



Without leaving the required minimum space around the unit. (as shown in the
drawing)



In scarcely ventilated areas.



On surfaces that are unable to support the weight of the unit without deforming,
breaking or causing vibrations during the use of the air conditioner.



In a position that does not enable the condensate drainage pipe to be correctly
installed. (at the end of the installation. It is always essential to check the efficiency
of the drainage system)

Indoor unit installation

1

Place the pattern sheet on the ceiling at the spot where you want to install
the indoor unit.

Note 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.

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.

CAUTION  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 4.92ft(1.5m),

it is required to prevent vibration.

4

Screw eight nuts to the suspension bolts making space for hanging the
indoor unit.

CAUTION You must install all the suspension rods.

5

Hang the indoor unit to the suspension bolts between two nuts.

Note Piping must be laid and connected inside the ceiling when

suspending the unit. If the ceiling is already constructed,
lay the piping into position for connection to the unit before
placing the unit inside the ceiling.

6

Screw the nuts to suspend the unit. Cut a pad stopper and place it on the
bracket at this time.

7

Adjust the unit to the appropriate position considering the installation area
for the front panel.
7-1 Place the pattern sheet on the indoor unit.
7-2 Adjust a space between the ceiling and the indoor unit by using the gauge

of dimensions.
7-3 Fix the indoor unit securely after adjusting level of the unit by using a leveler.
7-4 Remove the pattern sheet, connect the other cables and install the front

panel.

It is recommended to install the refnet joint before installing the indoor unit.

From factory the unit is supplied and set with a pre-charge of nitrogen gas.
(insert gas) Therefore, all insert gas must be purged before connecting the
assembly piping.

Unscrew the pinch pipe at the end of each refrigerant pipe.

Result: All inert gas escapes from the indoor unit.

Note To prevent dirt or foreign objects from getting into the pipes

during installation, do NOT remove the pinch pipe completely
until you are ready to connect the piping.
