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.) 3. Use the proper tools: Use the proper tools and test equipment, and know how to use equipment may cause problems laterintermittent contact, for example. 4. Power Cord: Prior to repair, check the power cord and replace it if necessary. Fig. 1-1 Avoid Dangerous Contact 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 30 megaohms. 7. Make sure that the grounds are adequate. Fig. 1-2 No Tapping and No Extension Cords 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. 10. Be sure to clean the unit and its surrounding area. Fig. 1-3 No Kids Nearby!

The installation area must be able to endure vibration from the unit. 3. 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. 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 (obtain a clearance of at least one meter). 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 an area not exposed to 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. Caution: Do not use the air conditioner in the following environments : greasy areas (including areas near machines), or marine areas. Contact your local dealer for advice.

Troubleshooting Check the basic checkpoints first to determine whether it is machine trouble or a problem in the operation method. When it is not related to the basic checkpoints, perform checking in accordance with the procedures of troubleshooting by symptom. 5-1 Basic Checkpoints for Troubleshooting 1) Is the voltage of the power source appropriate ? (1) It should be within the rating voltage ±10% range. (2) The air conditioner may not operate properly when the voltage is out of this range. 2) Is the connection with the fan motor, compressor wire, and starting condenser appropriately made ? 3) The symptoms listed in the table below are not indicative of machine trouble. Symptom Cause and check No operation • Check whether there is power failure or the power plug is pulled out. • Check whether the unit is stopped as a result of completion of the sleep time. • Pull out the power plug for ten seconds, and then insert it again. Air flows, but no cooling • Check whether the Air filter is clogged with dust or is dirty. • Check whether the desired temperature is too high. Set the desired temperature to a lower level than the current temperature. • Check whether it is in "FAN" mode. The remocon does not operate • Check whether battery is completely depleted. • Check whether the battery is properly inserted. • Check whether the receiving window of the remocon for the assembly main PCB is blinded. • Check whether the remocon is affected by jamming due to a neon sign.
