Carefully follow the precautions listed below because
they are essential to guarantee the safety of both the air
conditioner and the workers.
•
The unit contains moving parts, which should always
be kept out of the reach of children.
•
•
Always disconnect the air conditioner from the power
supply before servicing it or accessing its internal
components.
Do not attempt to repair, move, alter or reinstall the
unit. If performed by unauthorised personnel, these
operations may cause electric shocks or fires.
•
•
Verify that installation and testing operations are
performed by qualified personnel.
Do not place containers with liquids or other objects
on the unit.
•
•
Verify that the air conditioner is not installed in an
easily accessible area.
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
authorised centres or returned to the retailer so that it
can be disposed of correctly and safely.
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.

•
•
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 unauthorised 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.
Installation of 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 authorised 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.
Installation
•
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 air conditioner in environments with
hazardous substances or close to equipment that
release free flames to avoid the occurrence of fires,
explosions or injuries.
•
Do not use the units if damaged. If problems occur,
switch the unit off and disconnect it from the power
supply.
•
•
In order to help 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

(assembly cable)
NOTE
•
Each wire is labelled with the corresponding terminal
number.
•
Use shield cable (Category 5; less than 50pF/m) for
noisy environmental site.
•
Power supply cords of parts of appliances for outdoor
use shall not be lighter than polychloroprene sheathed
flexible cord. (Code designation IEC: 60245 IEC 66/
CENELEC: H07RN-F, IEC: 60227 IEC 53/CENELEC:
H05VV-F)
•
Power & Communication cable shall not exceed 30m.
•
For the terminal block wiring, use a wire with a
ring terminal socket only. Regular wires without a
ring terminal socket may become a hazard due to
overheating of the electrical contact during installation.
•
If you need to extend the pipe, be sure to extend the
cable too. The maximum length of each of the cable
and pipe used should not exceed 20(09/12) and
25(18/24) metres.
•
Do not connect two or more different cables to extend
the length. This connection may cause fire.
•
Each circular terminal must match the size of its
corresponding screw in the terminal block.
•
After connecting the cables, make sure that terminal
numbers on the indoor and outdoor units match.
•
Ensure that power and communication cables are
separated, they must not be in the same cable.
•
Connect the wires firmly so that wires cannot be pulled
out easily. (If they are loose, it could cause burn-out of
the wires.)

When installing, make sure there is no leakage. When
recovering the refrigerant, ground the compressor first
before removing the connection pipe. If the refrigerant
pipe is not properly connected and the compressor
works with the stop valve open, the pipe inhales the
air and it makes the pressure inside of the refrigerant
cycle abnormally high. It may cause explosion and
injury.
Leave the system in the standby mode.

Step 3.3 Evacuating the air
The outdoor unit is loaded with sufficient R-410A
refrigerant. Do not vent R-410A into atmosphere: it is a
fluorinated greenhouse gas, covered by Kyoto Protocol,
with a Global Warming Potential (GWP) = 2088. You
should evacuate the air in the indoor unit and in the
pipe. If air remains in the refrigerant pipes, it affects the
compressor. It may cause reduction of cooling capacity and
malfunction. Use a vacuum pump.

Open the valve of the low pressure side of manifold
gauge anticlockwise.
4
Evacuate the air in the connected pipes using the
vacuum pump for about 15 minutes.
5
R-410A is a mixed type of refrigerant. It is necessary for
recharging under conditions of liquid. When recharging
refrigerant from the refrigerant cylinder to the equipment,
take the following instructions:
Before recharging, check whether the cylinder has
a siphon or not. There are two ways to recharge the
refrigerant:
•
Make sure that pressure gauge shows -0.1 MPa
(-76 cmHg, 5 torr) after about 10 minutes. This
procedure is very important to avoid a gas leak.
•
Close the valve of the low pressure side of
manifold gauge clockwise.
•
Turn off the vacuum pump.
•
Check for 2 minutes if there is any pressure
change.
•
Remove the hose of the low pressure side of
manifold gauge.
Charge the refrigerant
standing the cylinder upright.
Charge the refrigerant turning
the cylinder upside down.
Set a valve cork of liquid and gas service port to the
open position.
<Cylinder with siphon>
<Cylinder without siphon>
Step 3.4 Adding refrigerant
If you use a pipe longer than the length specified in
the piping codes and standards, you must add 15g
(for09/12/18) and 30g (for24) of refrigerant
R-410A for each extra metre. If you use a pipe shorter that
the length specified in the piping codes and standards, the
evacuating time is normal. Refer to the Service Manual for
further details.
Siphon
NOTE
•
If R-410A refrigerant is charged with gas, the
composition of the charged refrigerant changes and
the characteristics of the equipment vary.
•
During the measuring operation of refrigerant quantity
added, use electronic scales. If cylinder doesn't have
siphon, upset it.
CAUTION
•
The remaining air in the Refrigeration cycle, which
contains moisture, may cause malfunction of the
compressor.
•
Always contact the service centre or a professional
installation agency for product installation.

WARNING
After installing the product, be sure to perform leak
tests on the piping connections.After pumping down
refrigerant to inspect or relocate the outdoor unit, be
sure to stop the compressor and then remove the
connected pipes.
‐ Do not operate the compressor while a valve is
open due to refrigerant leakage from a pipe or an
unconnected or incorrectly connected pipe. Failure
to do so may cause air to flow into the compressor
and too a high pressure to develop inside the
refrigerant circuit, leading to an explosion or
product malfunction.
