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 megaohms.
Fig. 1-1 Avoid Dangerous Contact
Fig. 1-2 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.
10. Be sure to clean the unit and its surrounding area.

∆T= -1°C, -2°C, 0°C+1°C+2°C
∆T is controlled by setting temperature
up/down key of remote controller
2. COOL MODE : The unit operates according
to the difference between the setting and
room temperature. (18°C~30°C)
3. HEAT MODE : The unit operates according
to the difference between the setting and
room temperature.(16°C~30°C)
*Prevention against cold wind : For about
3~5 minutes after initial operation, thermo
control or “de-ice”, the indoor fan will
either not operate or operate very slowly,
then switch to the selected fan speed. This
period is to allow the indoor unit's heatexchanger to prewarm before emitting
warm air.
*High temperature release function : The
outdoor unit for and compressor ON/OFF
control for safety operation, when the overheat is heat exchanger of indoor unit.
*De-ice : Deicing operation is controlled by
indoor unit's heat exchanger temperature
and accumulating time of compressor's
operation.
De-ice end by sensing of the processing
time by de-ice Condition.
Cool Operation (Set Temp:24°C+∆T)
Heat Operation (Set Temp : 22°C+∆T)
Operation Type
4. DRY MODE : Has 3 states, each determined
by room temperature.
The unit operates in DRY mode.
*Compressor ON/OFF Time is controlled
compulsorily(can not set up the fan speed,
always breeze).
*Protective function : Low temperature
release. (Prevention against freeze)
5. TURBO MODE : This mode is available in
AUTO, COOL, HEAT, DRY, FAN MODE.
When this button is pressed at first, the air
conditioner is operated “powerful” state for
30 minutes regardless of the set temperature, room temperature.
When this button is pressed again, or when
the operating time is 30 minutes, turbo
operation mode is canceled and returned to
the previous mode.
*But, if you press the TURBO button in DRY
or FAN mode that is changed with AUTO
mode automatically.
6. SLEEP MODE : Sleep mode is available
only in COOL or HEAT mode.
The operation will stop after 6 hours.
*In COOL mode : The setting temperature
is automatically raised by 1°C each 1hour
When the temperature has been raised by
total of 2°C, that temperature is maintained.
*In HEAT mode : The setting temperature
is automatically droped by 1°C each 1hour.
When the temperature has been droped by
total of 2°C, that temperature is maintained.
7. FAN SPEED : Manual (3 step), Auto (4 step)
Fan speed automatically varies depending
on both the difference between setting and
the room temperature.

in area not exposed to the rain or direct sun
light.
(Install a separate sunblind if exposed to
direct sun light.)
2. Make sure that you install the outdoor unit
in area allowing good air moment, not
amplifying noise or vibration, especially to
avoid disturbing neighbours.
(Fix the unit firmly if it is mounted in a
high place.)
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.

3-2-2(b) Purging the Unit
On delivery, the indoor unit is loaded with an inert gas.
All this gas must therefore be purged before connecting the
assembly piping. To purge the inert gas, proceed as follows.
Unscrew the caps at the end of each pipe.
Result : All inert gas escapes from the indoor unit.
•To prevent dirt or foreign objects from getting into
the pipes during installation, do NOT remove the
caps completely until you are ready to connect the
piping.

2. If you are using the extension, insulate the inside part of the extension drain hose with a shield.
Shield
3. Pass the drain hose under the refrigerant piping, taking care to keep the drain hose tight.
4. Pass the drain hose through the hole in the wall, making sure that it is sloping downwards, as
shown in the illustrations above.
The end of the drain
hose must NOT be
placed in water.
5cm
less
Do NOT bend the
hose in different
directions.
Keep a clearance of at
least 5cm between the
end of the hose and the
ground.
Do NOT place the end
