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.
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
a re satisfactory. Relocate the unit if neces­s a r y.
9 . Keep children away from the unit while it is
being re p a i re d .
1 0 . Be sure to clean the unit and its surro u n d-
ing are a .

Operating Instructions and Installation
1. A U TO MODE : In this mode, operation mode(COOL, HEAT, DRY) is selected auto­matically by the room temperature of initial o p e r a t i o n .
Room Temp Tr 21°C+T 21°C +T>Tr
T= -1°, -2°C, 0°C+1°C+2°CT is controlled by setting temperature
up/down key of remote contro l l e r
2. C O O L MODE : The unit operates accord i n g to the diff e rence between the setting and room temperature. (18°C~30°C)
3. H E AT MODE : The unit operates accord i n g to the diff e rence between the setting and room temperature.(16°C~30°C) * P revention against cold wind : For about 3~5 minutes after initial operation, thermo c o n t rol or “de-ice”, the indoor fan will either not operate or operate very slow­ly(510 rpm), then switch to the selected fan speed. This period is to allow the indoor unit's heat-exchanger to prewarm before emitting warm air. *High temperature release function : The outdoor unit for and compressor ON/OFF c o n t rol 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 compre s s o r ' s o p e r a t i o n . De-ice end by sensing of the pro c e s s i n g time by de-ice Condition.
Cool Operation (Set Temp:AUTO SETTING)

Operation Type
4. D RY MODE : Has 3 states, each determined by room temperature . The unit operates in DRY m o d e . *Co m p ressor ON/OFF Time is contro l l e d compulsorily(can not set up the fan speed, always bre e z e ) . * P rotective function : Low temperature release. (Prevention against fre e z e )
5. TURBO MODE : This mode is available in A U TO, COOL, HEAT, DRY, FAN MODE. When this button is pressed at first, the air conditioner is operated “powerful” state for 30 minutes re g a rdless of the set tempera­t u re, 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 A U TO mode automatically.
6 . S L E E P 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 main­t a i n e d . *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 main­t a i n e d .
7. FAN SPEED : Manual (3 step), Auto (4 step) Fan speed automatically varies depending on both the diff e rence between setting and the room temperature .

Select an area for installation that is suitable to the customer's needs.
3-2-1(a) Indoor Unit
1 . Make sure that you install the indoor unit in
an area providing good ventilation. It must not be blocked by an obstacle affecting the airflow near the air inlet and the air outlet.
2 . Make sure that you install the indoor unit in
an area allowing good air handling and endurance of vibration of the indoor unit.
3. Make sure that you install the indoor unit in an area where there is no source of heat or vapor nearby.
4 . Make sure that you install the indoor unit in

Wall 3.
Window frame 4 to 6.
3. Fix the installation plate to the wall in a manner appro­priate to the weight of the indoor unit.
If you are mounting the plate on a concrete wall with anchor bolts, the anchor bolts must not project by more than 20mm.
4. Determine the positions of the wooden uprights to be attached to the window frame.
3-2-2(b) Purging the Unit
5. Attach the wooden uprights to the window frame in a manner appropriate to the weight of the indoor unit.
6. Using tapped screws, attach the installation plate to the wooden uprights, as illustrated in the last figure oppo­site.
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 fol ­lows.
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.
