     be acted on the terminal. If connection or fixing is not perfect, it will cause heat-up or fire at the 
     connection.

7)  Wiring routing must be properly arranged so that control board cover is fixed properly. If 
     control board cover is not fixed perfectly, it will cause heat-up at connection point of terminal, 
     fire or electrical shock.

8)  When carrying out piping connection, take care not to let air substances other than the specified 
     refrigerant go into refrigeration cycle. Otherwise, it will cause lower capacity, abnormal high 
     pressure in the refrigeration cycle, explosion and injury.

9)  Do not modify the length of the power supply cord or use of extension cord, and do not share 
     the single outlet with other electrical appliances. Otherwise, it will cause fire or electrical 
     shock.
