OPERATING INSTRUCTIONS Special functions Refrigerant Leakage Detection With this new technology, the dipsplay area will appear EC and the indication lamps continue ﬂashing when the outdoor unit detects refrigerant leakage. Louver Angle Memory Function (optional) Within the scope of safety angle, it will memorize the open angle of horizontal louver. If it exceeds, it will memorize the boundry of safety angle. In the following circumstances, it will return to standard angle: 1) pressing the manual control button, 2) unplug and then plug in the machine. So we strongly suggest that the open angle of the horizontal louver should not be set too small, in case the condensed water forms and drops from the horizontal louver. SELF CLEAN function (optional) •Function used after the Shut Down of cooling operation to clean the Evaporator and keep it as fresh for the next operation. •The unit will operate as following sequence : FAN ONLY mode at Low fan speed, Heating operation with LOW fan speed(applicable to cooling & heating modles only), FAN ONLY operation, Stop Operation, Turn oﬀ. Note: •This function is only available under COOL(AUTO COOL, FORCED COOL) and DRY mode. •Before select the function, it is recommended to run the air conditioner under Cooling operation for about half an hour. Once the Self Clean function is activated, all TIMER setting will be cancelled. •During Self Clean operation, when press the SELF CLEAN button on the remote controller again will stop the operation and turn oﬀ the unit automatically. CLEAN AIR function (on some models) Improving the quality of indoor air is one of the purposes of an air conditioner. This air conditioner is equipped with ionizer or Plasma Dust Collector(Depending on speciﬁc conﬁguration of the model). With the anions generated by Ionizer, the air circulation of the air conditioner ﬁlls the room with refreshing, natural and healthy air. The Plasma Dust Collector generates a high voltage ionization zone, through which the air is converted to plasma. Inside the air most of the dust, smoke, and pollen particles are captured by the electrostatic ﬁlter. Anti-mildew function (optional) When turns oﬀ the unit on COOL, DRY, AUTO (Cool) mode, the air conditioner will continue operating for about 7-10 minutes (depending on models) at LOW fan speed. If turns oﬀ on HEAT mode, the unit will continue operating for about 30 seconds at LOW fan speed. This will help to dry up the condensed water inside the evaporator, and prevent the breeding of mildew. Under Anti-mildew operation, do not restart the air conditioner until the unit is completely oﬀ. NOTE: This manual does not include Remote Controller Operations, see the Remote Controller Manual packed with the unit for details. 5 For more information visit www.mrcool.com.

TROUBLESHOOTING Normal function of the air conditioner The following events may occur during normal operation. 1. Protection of the air conditioner. Compressor protection •The compressor can't restart for 3-4 minutes after it stops. Anti-cold air (Cooling and heating models only) •The unit is designed not to blow cold air on HEAT mode, when the indoor heat exchanger is in one of the following three situations and the set temperature has not been reached. A) When heating has just started. B) Defrosting. C) Low temperature heating. •The indoor or outdoor fan stop running when defrosting (Cooling and heating models only). Defrosting (Cooling and heating models only) •Frost may be generated on the outdoor unit during heat cycle when outdoor temperature is low and humidity is high resulting in lower heating eﬃciency of the air conditioner. •During this condition air conditioner will stop heating operation and start defrosting automatically. •The time to defrost may vary from 4 to 10 minutes according to the outdoor temperature and the amount of frost built up on the outdoor unit. 2. A white mist coming out from the indoor unit •A white mist may generate due to a large temperature diﬀerence between air inlet and air outlet on COOL mode in an indoor environment that has a high relative humidity. •A white mist may generate due to moisture generated from defrosting process when the air conditioner restarts in HEAT mode operation after defrosting. 3. Low noise of the air conditioner •You may hear a low hissing sound when the compressor is running or has just stopped running. It is the sound of the refrigerant ﬂowing or coming to a stop. •You can also hear a low "squeak" sound when the compressor is running or has just stopped running. This is caused by heat expansion and cold contraction of the plastic parts in the unit when the temperature is changing. •A noise may be heard due to louver restoring to its original position when power is turned on. 4. Dust is blown out from the indoor unit. •This is a normal condition when the air conditioner has not been used for a long time or during ﬁrst use of the unit. 5. A peculiar smell comes out from the indoor unit. •This is caused by the indoor unit giving oﬀ smells permeated from building material, from furniture, or smoke. 6. The air conditioner turns to FAN only mode from COOL or HEAT (For cooling and heating models only) mode. •When indoor temperature reaches the temperature setting on air conditioner, the compressor will stop automatically, and the air conditioner turns to FAN only mode. The compressor will start again when the indoor temperature rises on COOL mode or falls on HEAT mode (For cooling and heating models only) to the set point. 11 For more information visit www.mrcool.com. TROUBLESHOOTING 7. The air conditioner runs function after turning oﬀ the unit. •When turning oﬀ the unit under COOL(AUTO COOL, FORCED COOL) and DRY mode, the air conditioner will run Anti-mildew function for 7-10 minutes, if it turns oﬀ on HEAT mode, the unit will continue operating for about 30 seconds at LOW fan speed, then stop the operation and turn oﬀ the unit automatically. 8. Condensation •Condensation may develop on the surface of the indoor unit when cooling in a high relatively humidity (relative humidity higher than 80%). Adjust the horizontal louver to the maximum air outlet position and select HIGH fan speed. 9. Heating mode (For cooling and heating models only) •The air conditioner draws in heat from the outdoor unit and releases it via the indoor unit during heating operation. When the outdoor temperature falls, heat drawn in by the air conditioner decreases accordingly. At the same time, heat loading of the air conditioner increases due to larger diﬀerence between indoor and outdoor temperature. If a comfortable temperature can't be achieved by the air conditioner, we suggest you use a supplementary heating device. 10. Auto-restart function •Power failure during operation will stop the unit completely. •For the unit without Auto-restart feature, when the power restores, the OPERATION indicator on the indoor unit starts ﬂashing. To restart the operation, push the ON/OFF button on the remote controller. For the unit with Auto-restart feature, when the power restores, the unit restarts automatically with all the previous settings preserved by the memory function. 12 For more information visit www.mrcool.com.
