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.
Carefully follow the precautions listed below because they are essential to guarantee the safety

servicing it or accessing its internal components.
• Verify that installation and testing operations are performed by qualified
personnel.
