Be careful not to touch the metal parts with your hands. Do not use benzine, thinner, polishing powder, or insecticide. Use only diluted mild detergents. Do not expose parts to direct sunlight, heat, or flames to dry. Do not use water hotter than 50°C. Air filter (Catechin air filter) • Clean every 2 weeks • Remove dirt by a vacuum cleaner, or wash with water. • Dry it well in shade before installing it. Deodorizing filter (Option) Back side of air filter • Clean every 2 months. • Soak the filter together with its frame in lukewarm water and wash it. • After washing, dry it well in shade and put it back to its original position. Install all tabs of the air filter. • Replace it with a new air cleaning filter every year for best performance. • Parts Number MAC-1700DF (with frame) Parts Number MAC-2100DF (no frame) Air cleaning filter (Option) • If the air cleaning filter is clogged, it may lower the unit’s capacity or cause condensation at the air outlet. • capacity or cause condensation at the air outlet. • The air cleaning filter is disposable. • If the color of the filter turns brown, replace the filter at once. • Replace it with a new air cleaning filter every 4 months for best performance. • Parts Number MAC-1200FT (with frame) Parts Number MAC-1600FT (no frame) Note: - Clean the filters regularly for best performance and to reduce power consumption. En-6 • OPERATING INSTRUCTIONS • When you think that trouble has occurred Symptom Explanation & Check points Remote controller The display on the remote controller does not appear or it is dim. The indoor unit does not respond to the remote control signal. • Are the batteries exhausted? [Page3_^^^H • Is the polarity (+, -) of the batteries correct? • Are any buttons on the remote controller of other electric appliances being pressed? Does not cool The room cannot be cooled sufficiently. • Is the temperature setting appropriate? • Is the fan setting appropriate? Please change fan speed to higher setting. • Are the filter clean? • Is the fan or heat exchanger of the indoor unit clean? • Are there any obstacles blocking the air inlet or outlet of the indoor or outdoor unit? • Is a window or door open? • When a ventilation fan or a gas cooker is used in a room, the cooling load increases, resulting in an insufficient cooling effect. • When the outside temperature is high, the cooling effect may not be sufficient. Airflow The air from the indoor unit smells strange. • Are the filter clean? • Is the fan or heat exchanger of the indoor unit clean? • The unit may suck in an odor adhering to the wall, carpet, furniture, cloth, etc. and blow it out with the air. Sound Cracking sound is heard. • This sound is generated by the expansion/ contraction of the front panel, etc. due to change in temperature. The sound as burbling is heard. • This sound is heard when the outside air is absorbed from the drain hose by turning on the range hood or the ventilation fan, making water flowing in the drain hose to spout out. This sound is also heard when the outside air blows into the drain hose in case the outside wind is strong. Mechanical sound is heard from the indoor unit. • This is the switching sound in turning on/off the fan or the compressor. The sound of water flowing is heard. • This is the sound of refrigerant or condensed water flowing in the unit. Even if these items are checked, when the unit does not recover from the trouble, stop using the air conditioner and consult your dealer. Symptom Explanation & Check points Indoor Unit The unit cannot be operated. • Is the breaker turned on? • Is the power supply plug connected? • Is the ON timer set? The unit cannot be operated for about 3 minutes when restarted. • This protects the unit according to instructions from the microprocessor. Please wait. The fan stops during the DRY operation. • In DRY operation, the unit operates using the same refrigerant circuit as in COOL operation. DRY operation time has to be reduced in order to lower humidity without much room temperature decreasing. So the compressor sometimes stops, and at the same time the indoor fan stops. This prevents water condensed on the heat exchanger from evaporating again. Mist is discharged from the air outlet of the indoor unit. • The cool air from the unit rapidly cools moisture in the air inside the room, and it turns into mist. The swing operation of the HORIZONTAL VANE is suspended for a while, then restarted. • This is for the swing operation of the HORIZONTAL VANE to be performed normally. The air flow direction changes during operation. The direction of the horizontal vane cannot be adjusted with the remote controller. • When the unit is operated in COOL or DRY mode, if the operation continues with air blowing down for 0.5 to 1 hour, the direction of the air flow is automatically set to position (1) to prevent water from condensing and dripping. The unit starts operation by itself when the main p...
