What safety precautions should I follow when using or installing the air conditioner?

Always perform grounding work, as lack of grounding may cause electric shock, and install an air leakage breaker with a dedicated switching board. Never operate the unit with wet hands, in a damp environment, or by plugging and unplugging the power cord to start and stop it. If strange sounds, smell, or smoke come from the unit, unplug it immediately, and contact an authorized service technician for any repairs or maintenance. (Pages 3, 5)
