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-

3-1-1 Name & Function of Key in remote controller

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°C
∆T 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)

Heat Operation (Set Temp : 22°C+∆T)

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 .

8 . C O M P U L S O RY O P E R ATION :

For operating the air conditioner without
the remote contro l l e r.
* A U TO : The operating is the same func­tion that A U TO MODE in the remote con­t ro l l e r.

Pipe hole
(ø65mm)

1. Determine the position of the pipe and drain hose hole
using the right figure and drill the hole with an inner
diameter of 65mm so that it slants slightly downwards.

2. If you are fixing the indoor unit to a… Then follow Steps…

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.
