1. Precautions
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-
ment parts. (Also, we recommend re p l a c i n g
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- i n t e r m i t t e n t
contact, for example.
4 . Power Cord: Prior to re p a i r, 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 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
g round terminal. The resistance must be
g reater than 30 megohms.

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%.
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 6 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 INDOOR FAN should operate.
In a HEAT operation mode, the compressor does not
operate at a room temperatrue 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 Compressor of the outdoor unit is operating although it is
turned off in a HEAT mode.
6 Timer LED only of the indoor unit lights up and the
air conditioner does not operate.
7 The compressor and indoor fan stop intermittently in HEAT
mode.
8 Indoor fan and outdoor fan stop operation intermittently in
a HEAT mode.
9 The compressor stops intermittently in a COOL mode or DR Y
mode, and fan speed of the indoor unit decreases.
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.
C o m p ressor operation is controlled automatically in DRY mode
depending on the room temperature and humidity.
When the unit is turned off while de-ice is activated, the comperssor
continues operation for up to 9 minutes (maximum) until the deice is
completed.
Timer is being activated and the unit is in ready mode.
The unit operates normally if the timer operation is cancelled.
The compressor and indoor fan stop intermittently if room temperature
exceeds a setting temperature in order to protect the compressor from
overheated air in a HEAT mode.
The compressor operates in a reverse cycle to remove exterior ice in a
HEAT mode, and indoor fan and outdoor fan do not operate intermttently for within 20% of the total heater operation
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.
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 . 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).
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 .
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.
Replace it with a new part.
Check the operation of the new part.
The repair is completed.
