The Foremost Inspecting Items ⑴The input voltage must be within +10% tolerance of the rated Voltage. If it is not the case, the air-conditioner will probably not work normally. ⑵Check the connecting cord between indoor unit and outdoor unit to see if it is properly connected. The connecting must be done according to the wiring diagram, please also notice that even different models may have the connecting cord of the same specification. Please check if the marks at the connecting terminal and the marks on the cord can match, otherwise, the air-conditioner will not work normally. ⑶If the following phenomena are found, the problem is not from the air-conditioner itself. 11 NO. 1 2 3 Problems The motor is heard operating but the air-conditioner dose not work when the indoor unit is powered on The compressor stops running but the indoor fan motor keeps working when it is at cooling mode with the indoor temperature higher than set temperature. The compressor works discontinuously at dehumidifying mode. 4 The air-conditioner does not work while the LED display is on. 5 The compressor works discontinuously at cooling and dehumidifying mode, and the indoor fan motor slows down. Causes Since the air-conditioner is powered on, it will come to working condition as long as you press the ON/OFF button of the remote control and the Signal is well received. If you turn off the air-conditioner and restart it immediately, it will return to normal in 3 minutes, after that, the air-conditioner will automatically adjust the indoor fan speed to what you set. The air-conditioner will automatically control the working of the compressor according to the inside temperature The TIMER is set with the air-conditioner; it will be in hold on condition. If the TIMER setting is cancelled, the air-conditioner will return to normal working condition The compressor stops internally or the fan motor slows down to prevent the indoor heat exchanger from being frozen. 12 2. No Power Display ⑴Items a) Check if the input voltage is correct? b) Check if the AC power supply connecting is correct? c) Check if the output voltage of the manostat L7805 (IC2) is correct? ⑵Trouble shooting procedure 13 3. The Indoor Fan Motor Does Not Work ⑴Items a) Check if the indoor fan motor is connected correctly to the connector (CN8)? b) Check if the AC input voltage is correct? c) Check if the IC of indoor fan motor is connected correctly to the connector (CN2)? d) Check if the capacity of indoor fan motor is connected correctly to the connector (CN8)? ⑵Trouble shooting procedure 14 4. The Outdoor Unit Does Not Work ⑴Items a) Check if the input voltage is correct? b) Check if the wire connection of the outdoor connecting terminal is correct? ⑵Trouble shooting procedure 15 5. The Step Motor Does Not Work ⑴Items a) Check if the input voltage is correct? b) Check if the step motor controlling the up-down movement firmly connected to Cn2? ⑵Trouble shooting procedure 16 6. Heating Mode Can Work, But No Hot Air Blow ⑴Check if the set temperature is lower than the indoor temperature? ⑵Check if the indoor PCB is connected to the terminal correctly? 17 7. Remote Control Can Not Work Trouble shooting rocedure 18 The Klimaire logo is a registered Trademark of Klimaire Products Inc. Copyright 2016 Klimaire Products Inc.
