1 . Warning: Prior to re p a i r, disconnect the
power cord from the circuit bre a k e r.
2 . Use proper parts: Use only exact re p l a c e m e n t
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 re p a i r, check the power
c o rd and replace it if necessary.
5 . Avoid using an extension cord, and avoid tap-
ping into a power cord. This practice may result in malfunction or fire .
6 . After completing repairs and re a s s e m b l y,
check the insulation resistance. Pro c e d u re : Prior to applying power, measure the re s i s­tance between the power cord and the gro u n d terminal. The resistance must be greater than 30 megohms.

5. Troubleshooting
5-1 Items to be checked first
1 ) Is the voltage of the power corre c t ?
The input voltage shall be rating Voltage ±10% range. The airconditioner may not operate properly if the voltage is out of this range.
2 ) Is the link cable linking the indoor unit and the outdoor unit linked pro p e r l y ?
The indoor unit and the outdoor unit shall be linked by 5 cables. Check the terminals if the indoor unit and outdoor unit are properly linked by the same number of cables. Otherwise the airconditioner may not operate pro p e r l y.
3 ) When a problem occurs due to the contents illustrated in the table below it is a symptom not related to the
malfunction of the airc o n d i t i o n e r.
NO Operation of air conditioner
1 The COOL operation indication LED (Green) blinks when a
power plug of the indoor unit is plugged in for the first time.
2 In a COOL operation mode, the compressor does not
operate at a room temperature higher than the setting temperature that the IN DOOR FAN should operate. In a HEAT operation mode, the compressor does not operate at a room temperature lower than the setting temperature that indoor fan should operate.
3 Fan speed setting is not allowed in AUTO or DRY mode.
4 Compressor stops operation intermittently in DRY mode.
5 Timer LED only of the indoor unit lights up and the
air conditioner does not operate.
Explanation
It indicates power is on. The LED stops blinking if the operation
ON/OFF button on the remote control unit is pushed.
In happens after a delay of 3 minutes when the compressor is reoper­ated. The same phenomenon occurs when a power is on. As a phenomenon that the compressor is reoperated after a delay of
3 minutes, the indoor fan is adjusted automatically with reference
to a temperature of the air blew
The speed of the indoor fan is set to LL in DRY mode. Fan speed is 5 steps is selected automatically in AUTO mode.
Compressor operation is controlled automatically in DRY mode
depending on the room temperature and humidity.
Timer is being activated and the unit is in ready mode. The unit operates normally if the timer operation is cancelled.
6 The compressor stops intermittently in a COOL mode or DRY
mode, and fan speed of the indoor unit decreases.
The compressor stops intermittently or the fan speed of the indoor unit decreases to prevent inside/outside air frozen depending on the inside/outside air temperature.
4 ) Indoor unit observes operation condition of the air conditioner, and displays self diagnosis details
on the display panel.

5-3 PCB Inspection
5-3-1 Cautions for Part Replacement
1 . The human body carries much static
e l e c t r i c i t y. Before touching a part for re p a i r, replacement or the similar purpose, be sure to touch a grounded metallic portion by hand to let the static electricity go thro u g h 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 t rouble will possibly be caused in the part.
Troubleshooting
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 c o v e red with an oxide film, solder cannot a d h e re to the lead wires if not polished.
6 . When soldering any part, care should be
e x e rcised not to apply any high-wattage soldering iron to the part for a long time. Some parts are of so low a heat re s i s t a n c e that they may be broken or have the p roperties changed if a soldering iron is so applied (Otherwise, the pattern may possibly be separated and raised).
3. B e f o re replacing any parts, be sure to turn o ff 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 re s u l t .
4. During replacement or repair of a part, c a refully handle it : The printed circ u i t b o a rd 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.
5-3-2 Procedure
The parts should be replaced in the following pro c e d u re .
Check for any faulty part.
Detach the faulty part.
7. The heat of the soldering iron should be t r a n s f e red to the entire object to be soldere d . If the solder pieces are not well fused due to i n s u fficient transfer of the heat from the soldering iron, no satisfactory electrical continuity can be assured even if the s o l d e red 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 circ u i t .
Replace it with a new part.
Check the operation of the new part.
The repair is completed.
