• 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.
• 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 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 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
