SAFETY PRECAUTIONS 

To prevent injury to the user, other people, or property damage, the following instructions must be 
followed. Incorrect operation due to ignoring of instructions may cause harm or damage.   
 
Install the unit only when it complies with local regulations, by-laws and standards. Check the main 
voltage and frequency. This unit is only suitable for earthed sockets. 
 
The following safety precautions should always be taken into account: 

-

 

Be sure to read the following WARNING before installing the unit. 

-

 

Be sure to observe the cautions specified here as they include important items related to safety. 

-

 

After reading these instructions, be sure to keep it together with the manual in a handy place for 
future reference. 

 

 

 
Do not install the unit yourself. 
Incorrect installation could cause injury due to fire, electric shock, the unit falling or leakage of water. 
Consult the dealer from whom you purchased the unit or a specialized installer. 
 
Install the unit securely in a place. 
When insufficiently installed, the unit could fall causing injury. When installing the unit in a small room, 
please take measures (like sufficient ventilation) to prevent the asphyxia caused by the leakage of 
refrigerant.   
 
Use the specified electrical wires and attach the wires firmly to the terminal board (connection in such 
a way that the stress of the wires is not applied to the sections). 
Incorrect connection and fixing could cause a fire. 
 
Be sure to use the provided or specified parts for the installation work. 
The use of defective parts could cause an injury due to possible fire, electric shocks, the unit falling etc. 
 
Perform the installation securely and please refer to the installation instructions. 
Incorrect installation could cause an injury due to possible fire, electric shocks, the unit falling, leakage 
of water etc. 
 
Perform electrical work according to the installation manual and be sure to use a dedicated section. 
If the capacity of the power circuit is insufficient or there is an incomplete electrical circuit, it could 
result in a fire or an electric shock. 
 
The unit must always have an earthed connection. 
If the power supply is not earthed, you may not connect the unit.
