1. Precautions

1. 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 them. Using defective tools or test equipment may cause problems later-intermittent contact, for example. 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 30 megohms. 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. 10. Be sure to clean the unit and its surrounding area.

5-3 PCB Inspection

5-3-1 Cautions for Part Replacement
1. The human body carries much static electricity. Before touching a part for repair, replacement or the similar purpose, be sure to touch a grounded metallic portion by hand to let the static electricity go through the matallic portion to the earth. Espectially when handling any micro computer or IC, carefully remove such static electricity before touching them. 2. When repairing any part on a work bench, be sure to place an insulative sheet on the bench and always keep the sheet surface neat without any metal fragments. If any such fragment touches a part, a secondary trouble will possibly be caused in the part. 3. Before replacing any parts, be sure to turn off the power supply. If such replacement is done with the power supply kept on, an electric shock, short circuit or destruction of a part may result. 4. During replacement or repair of a part, carefully handle it : The printed circuit board has fine lead wires (jumper wires) and glass-made parts (diode) on its substrate. So if a circuit board is roughly handled, such lead wires and parts will be easily broken or damaged by bending or shock. 5. When soldering the lead wires of any new part, be sure to polish them using an emery paper or the like before solding them. Since the lead wires of any new part are covered with an oxide film, solder cannot adhere to the lead wires if not polished. 6. When soldering any part, care should be exercised not to apply any high-wattage soldering iron to the part for a long time. Some parts are of so low a heat resistance that they may be broken or have the properties changed if a soldering iron is so applied (Otherwise, the pattern may possibly be separated and raised). 7. The heat of the soldering iron should be transfered to the entire object to be soldered. If the solder pieces are not well fused due to insufficient transfer of the heat from the soldering iron, no satisfactory electrical continuity can be assured even if the soldered objects appear well connected to each other. 8. The solder used should be limited to a minimum. If excessive solder is used, it will cause inter-pattern contact, which may cause malfunction of the circuit.

5-3-2 Procedure

The parts should be replaced in the following procedure. Check for any faulty part.

Detach the faulty part.

Replace it with a new part.
Check the operation of the new part.

The repair is completed.

If necessary, set the air conditioner going a short time before you wish to use the room. When outside temperatures are low and humidity is high, frost may form in the outdoor unit when heating with your air conditioner. If this happens: x The heating operation is stopped. x The Deice mode is triggered automatically for about seven minutes x The OPERATION indicator on the indoor unit lights up red No intervention is required from you; after about seven minutes, the air conditioner starts operating again normally. If both the indoor and outdoor temperatures are high and you select the Heat mode, the outdoor units fan and compressor may stop at times. This is normal; simply wait until the air conditioner switches on again. If a power failure occurs when the air conditioner is operating, the unit is switched off.
