If not, it may cause an electric shock, a fire or explosion because there are possibilities of the electrical
leakage or overcurrent, etc. Contact your distributor or contractor.
● If abnormality (burnt odor, etc.) occurs, stop the operation and turn OFF the main power source
immediately. If not, it may cause breakage of the product, an electric shock or a fire.
Contact your distributor or contractor.

dangerous that the indoor fan and electrical parts are exposed. In addition, it may cause an electric shock
due to touch the electrical parts.
● When the air conditioner is necessary to be repaired or relocated, contact your distributor or contractor.
If the repair and the installation are not completed, it may cause an electric shock or a fire.
● Do not perform the installation work, the refrigerant piping work, the drain pump, the drain piping and
electrical wiring connection without tuning OFF the main power source.
It may cause an electric shock or injury.
● Perform the maintenance work with stable footing. If not, it may cause falling or injury.
● Do not spray water or detergent to the indoor unit when performing the maintenance work.
It may cause an electric shock or a fire by electrical short-circuit.
● Protect securely the electrical parts and connectors not to splash water when performing the maintenance
work. If not, it may cause an electric shock or a fire by electrical short-circuit.
