What safety precautions should I follow when cleaning my LG LWG07-Series air conditioner?

Before cleaning, always disconnect the unit from power and ensure the circuit breaker is also turned off, since the fan spins at very high speeds and could cause injury if accidentally started. Never use water to clean the interior of the unit, as it can damage insulation and cause electric shock. Do not touch metal parts when removing the filter, as sharp edges can cause cuts. (Pages 5–6)
