. Precautions. Warning: Prior to repair, disconnect the power cord from the circuit breaker. 2. Use proper parts: Use only exact replacement parts. (Also, we recommend replacing parts rather than repairing them.). Use the proper tools: Use the proper tools and test equipment, and know how to use equipment may cause problems laterintermittent contact, for example. Fig. Avoid Dangerous Contact 4. Power Cord: Prior to repair, check the power cord and replace it if necessary. 5. Avoid using an extension cord, and avoid tapping into a power cord. This practice may result in malfunction or fire. 6. After completing repairs and reassembly, check the insulation resistance, Procedure: Prior to applying power, measure the resistance between the power cord and the ground terminal. The resistance must be greater than 0 megohms. Fig. 2 No Tapping and No Extension Cords 7. Make sure that the grounds are adequate. 8. Make sure that the installation conditions are satisfactory. Relocate the unit if necessary. 9. Keep children away from the unit while it is being repaired. 0. Be sure to clean the unit and its surrounding area. Fig. No Kids Nearby!

. Installation and Operating Instructions Installation Selecting Area for Installation Select an area for installation that is suitable to the customer s needs.. Make sure that you install the unit in an area providing good ventilation. The air conditioner must not be blocked by any obstacles affecting the airflow near the air inlet and the air outlet. 2. Make sure that you install the unit in an area that allows good air handling. The installation area must be able to endure vibration from the unit.. Make sure that you install the unit away from heat or vapor. 4. Make sure that you install the unit in an area which is cool and has adequate space. 6. Make sure that you install the unit in an area which provides easy drainage for condensed water. 7. Make sure that you install the unit in area not exposed to the rain or direct sunlight. (Install a separate sunblind if exposed to direct sunlight). 8. Make sure that you install the unit in an area allowing good air movement. Do not install it in a space that would cause noise amplification of noise. 9. Fix the unit firmly if mounted in a high place. 5. Make sure that you install the unit in an area away from TVs, audio units, cordless phones, fluorescent lighting fixtures and other electrical appliances (at least meter clearance). Caution: It is harmful to the air conditioner if it is used in the following environments : greasy areas (including areas near machines), salty areas such as coast areas, areas where sulfuric gas is present (such as hot spring areas), Contact your dealer for advice.

Follow this procedure : 5 Method of Troubleshooting and Cautions on Troubleshooting 5 Check the Voltage of the power source. The input voltage shall be 5V/60Hz The air conditioner may not operate properly if the voltage is out of this range. 52 Check weak and fragile parts. 5 Check the connection of terminals. 54 When a malfunction occurs: Malfunction Check point Possible cause ➀ ➁ ➂ ➃ The compressor does not operate. The motor does not operate. The cooling capacity is low. Noise. check the thermostat position.. Setting temp is lower than room temp. 2. check the connection of the lead wire. 2. Disconnection of the lead wire.. check the over load protector.. O.L.P is faulty 4. check the compressor. 4. Compressor is faulty. check the connection of the lead. disconnection of the lead wire wire & switch. 2. switch is faulty. 2. check the motor. motor is faulty. check the refrigerant leakage.. Caused by the pipe crack 2. check the evaporator condition 2. shortage of refrigerant ( freezing, blocked with dusts, etc. ). clean the evaporator & air filter. Difference of temp. exists between the suction side and the discharge side at least 2 C Standard condition Indoor : 27 C outdoor : 5 C. check vibration of the pipe. pipes are contact with the other parts. 2. check the propeller fan and blower 2. the hex nut is loose ( not loose or broken ).. the parts are broken. check bearing noise of the motor 4. motor is faulty 4. check the compressor noise against 5. compressor is faulty that of other compressors.
