To avoid electric shocks or fires, install an earth leak 
detector.

 

 

Ensure the unit is grounded.

 

To avoid electric shocks, ensure the unit is grounded and that 
the earth wire is not connected to a gas or water pipe, lightning 
conductor, or telephone earth wire.

 

 

To avoid injury, do not remove the fan guard on the 
outdoor unit.

 

 

Do not use the unit if your hands are wet.

 

Doing so puts you at risk of an electric shock.

 

 

Do not touch the heat exchanger fins.

 

These fins are sharp and you could cut you.

 

 

Do not place items which might be damaged by moisture 
under the indoor unit.

 

Condensation may form if the humidity is above 80 percent, if 
the drain outlet is blocked or if the filter is polluted.

 

 

Check the unit stand and fitting for damage after the unit 
has been running for a long time.

 

If the stand is damaged, the unit may fall and cause an injury.
