37 Changing batteries and notices.slightly to press the place to take out the back cover of wireless remote control.(as shown in figure) 2. Take out the old batteries. (As show in figure) 3. Insert two new AAA.5V dry batteries, and pay attention to the polarity. (As show in figure) 4. Attach the back cover of wireless remote control. (As show in figure) Fig. NOTE: When changing the batteries, do not use the old or different batteries, otherwise, it can cause the malfunction of the wireless remote control. If the wireless remote control will not be used for a long time, please take them out, and don't let the leakage liquid damage the wireless remote control. The operation should be in its receiving range. If the wireless remote control can not operate normally, please take them out, after 30s later and reinsert, if they cannot normally run, please change them. It should be placed at where is m away from the TV set or stereo sound sets. Fig.2

48 8.2 No power supply Check if switch is in off position, if socket and plug is disconnected, and check if power supply failed or cut off. Fuse burn-out Replace fuse Power voltage is too low Check power voltage. If it is 0% below rated voltage,inspect and repair line Switch failure Check if option switch (ON, OFF) is disconnected with line, has mechanical failure;use universal meter to check if contacts of switch are conducting; if not, replace it with a new one with the same model and spec. Air-conditioning unit does not run Failure of crystal oscillator or reset circuit Connecting line is loose or incorrect. Replace components with failure Correct wrong connection by referring to the electrical diagram attached on unit Transformer is broken Replace transformer Controller is broken Replace controller Temp contrller is improperlly adjusted Adjust temp lower (or higher during heating) Air conditioning unit is running but there is no cooling effect (or no heating effect) Too much dust on filter Blockage of heat exchanger Fan speed is set too low Clean filter Clean the dust on the surface of heat exchanger Set fan speed at middle or high Fan doesn't run or fan speed is too low. Wrong connection of wire 2.If capacitor is broken 3.Malfunction of motor Correct wire connection or replace broken parts 46

49 Insufficiency or leakage of refrigerant Blockage in cooling system Check leakage,carryout vacuum-pumping after repairing leakageand chargerefrigerant according to requirements. Observe the condensation condition of evaporator orthe reading of high pressure meter to judge if thesystem is blocked; deal with the system accordingly Excess refrigerant Charge excess refrigerant in the system Low efficiency of compressor itself Replace it with a new compressor Air conditioning unit is running but there is no cooling effect (or no heating effect) Condensate can not be smoothly discharged During heating,electric heater does not work Outdoor temperature is too high If cooling (heating) load is proper The room is not properly sealed and there is frequent passage of personnel, or when cooling, there isheating device in the room. Clear the obstacle.connecting wire is loose 2.Fuse is off 3.Thermostator is broken 4.Electric heater is broken 5.Correct wire connection or replace broken parts It is available to install a shade guarding against sun and rain..if the maximum cooling capacity still could not,replace the unit. Check the forecasted load of cooling (heating). Keep a proper sealing for the room and it is recommended not to use electric appliance with too much heating when cooling. The voltage is not stale Check the reason and correct it. Wrong wire connection Check for the circuit with the circuit diagram Fan doesn't run during air supply Damage of fan capacitor The motor winding is of broken circuit or short circuit or the built in temperature limiter device in open circuit due to over heat. Change fan capacitor of same model and specification Replace the failed components. Malfunction of controller Replace the controller The compressor is not running (controller with output) Breakage of compressor capacitor or wrong wire connection The motor of compressor is damaged. The compressor is jammed or blocked. Change capacitor. And connect the circuit diagram correctly Check with a multimeter if the enclosed motor windings of compressor is with short or broken circuit or earthing.if so,it is needed to replace it with the same type and specifications. Knock the compressor housing with a rubber bar or with a hammer padding with a wood, the compressor might be shocked and run. If not, change the compressor. 47

50 Shortage or too much of refrigerant Adjust the volume of refrigerant Protector is activated due to too overheat of compressor. The capillary is block and the sucking temperature is increased. Compressor does not run, jammed or blocked, and the discharge valve is damaged. Change capillary Change compressor Failure exists in the protector. Check with a multimeter and see if the contacts of compressor are normal when they are not overheated. I f not, change the protector. The compressor is frequently ON/OFF. Abnormal power voltage The system is of a bad heat sinking and the ventilation is poor. The air conditioner capability does not match the area of the room, i.e. so called "Big system, small room". Check for the causes. Improve the power supply conditions,and add voltage regulated power supply. Clean the dust deposited on the system and remove obstacles at the aid discharge vent. Select an air conditioner meeting the area of the room. Receiving distance of remote control is short Shortage of battery capacity Replace the battery LED display flashes or when pressing the transmit button the entire screen is displayed. Shortage of battery capacity Replace the battery LED display is found short of stroke. The LED frame is not properly fixed. Fix the LED frame properly. The installation of compressor is not proper and the ground leg is not stable. The system is not placed levelly. Check if the ground leg is stable. Adjust the location of the unit. Abnormal noise and vibration The system stand is not stable. Foreign object exists in the unit. Fix the stand or install again. Take out the foreign object. Loose of screw Tighten the screw. Notice: The above malfunction analysis is only for reference. There is no malfunction related to heaitng for cooling only unit. 48
