For environmental conservation it is strongly recommended that the indoor and outdoor units of the air conditioner in use be cleaned and maintained regularly to ensure efficient operation of the air conditioner when the air conditioner is operated for a long time periodic maintenance once a year is recommended furthermore regularly check the outdoor unit for rust and scratches and remove them or apply rustproof treatment if necessary as a general rule when an indoor unit is operated for 8 hours or more daily clean the indoor unit and outdoor unit at least once every 3 months ask a professional for this cleaning maintenance work such maintenance can extend the life of the product though it involves the owner s expense failure to clean the indoor and outdoor units regularly will result in poor performance freezing water leakage and even compressor failure p.29
Caution p.29
Be sure to clean the heat exchanger with pressurized water if an commercially detergent strong alkaline or acid cleaning agent is used the surface treatment of the heat exchanger will be marred which may degrade the self cleaning performance for details contact the dealer p.29
