1. INSTALLATION GUIDE
1 INSTALLATION PLACE
◆Indoor unit ◆Outdoor unit
Secure enough space from the neighboring
objects as shown below.
This is required to operate the unit
efficiently.
• Flat and strong place in the room
• No obstacles in front of air in/out grille
• Easy place to connect drain hose to outside of room
• Easy place to connect copper tube with outdoor unit
•Secure enough distance from neighboring objects as
shown below.
•Secure enough distance from neighboring objects as
shown below.
• A place no reach of direct ray of sun (if necessary, shield the
light)
• No obstacles in front of air in/out grille
• A place having a drain out-let
• Easy place to connect copper tube with indoor unit
• Secure enough distance from neighboring objects as shown
below.
(Indoor unit) (Outdoor unit)
CAUTION : Do not hang the outdoor unit on the wall of building, in case of falling, it may cause a serious trouble and damage.
2 SPACE TO INSTALL
3 INSTALLATION OF INDOOR UNIT
1) Drain hose should maintain downward
slope to outside of room.
2) Indoor unit should be fixed firmly with the
bracket to avoid falling down. The bracket
has several holes to fix the unit any
direction needed (fore/back/right/left)

REFRIGERANT TUBE CONNECTION
1) Cushion rubbers absorb vibration of
outdoor unit
2) The unit must be grounded for safety in
accordance with local electrical codes.
(Grounding resistance should be under
100 ohms
■ Specification and method of copper tube
• Connection method of copper tube is to make connection with flare nut at the end of the copper tube with a flare tool.

2
CAUTION
• Use designated diameter and thickness of tube.
• Connect all tube as short as possible and fix firmly.
• Less than 3M of the difference of height between indoor and outdoor unit is desirable.
• Fill up more refrigerant if the connection tube is longer than 5M (130g/M).
(The refrigerant volume filled from the factory is suitable for 5M connection)
• Be careful not to let in any dust or motes into the tube when the tube passes the wall.
• When insulating the connection, use foam rubber or equivalent.

ELECTRICAL WIRING
CAUTION
•Be sure to use designated wires and make it as short as possible
•Use an exclusive power supply for the air conditioner
•Use an electricity leakage interrupter having suitable capacity.
•Grounding resistance should be under 100 ohms and the grounding wire should be connected firmly to the
terminal of out door unit.
■ Wire connection of indoor and outdoor unit
•When connecting wires of indoor and outdoor unit, the numbers of terminal block and terminals of connecting wires should
match exactly as shown below.
•Terminals of connecting wires should be fixed firmly using wire fixing tool to the same direction of terminal board.

Replacing Batteries
1. Slide down further to access
the battery compartment. 2. Insert two “AAA”size
Alkaline batteries
following the polarity
diagram below.
BATTERY PRECAUTIONS
The precautions below should be followed when using batteries in this device:
1. Use only the size and type of batteries specified.
2. Be sure to follow the correct polarity when installing the batteries as indicated in the battery compartment.
Reversed batteries may cause damage to the device.
3. Do not mix different types of batteries together (e.g. Alkaline and Carbon-zinc) or old batteries with fresh.
4. If the device is not to be used for a long period of time, remove the batteries to prevent damage or injury
from possible battery leakage.
5. Do not try to recharge batteries not intended to be recharged; they can overheat and rupture. (Follow battery
manufacturer’s directions).

15
If you set time in OFF-Timer Mode, the unit will stop at the set time.
If you set time in ON-Timer Mode, the unit will run at the set time.
(1) Range of setting temperature: 16~32°C
(2) Setting temperature: Operating temperature of compressor
(3) During the time of test operating, Fan (Indoor, Outdoor) and Compressor is running regardless of room
temperature.
If the Indoor Unit Display receive the signal of Remote Controller, you can hear the signal "beep –" or "beep,
beep".
(1) In the case of receiving ON/OFF signal-“beep”“beep”

(1) To set the save Mode, press the save Mode button during Cool or Heat mode.
By applying the save Mode, the desired temperature is adjusted gradually enough not to feel the change of
temperature, so that electricity cost can be cut down and also over-air cooling and-heating can be prevented.
(2) For changing the temperature.
(3) To cancel save mode, press the SAVE button again.

Frost Prevention of Indoor Unit
When the unit operates at low ambient temperature, frost may appear on the Evaporator. When the indoor coil
temperature is lower than 0°C at the end of 10 minutes of continuous compressor operation from the start, the
microcomputer of the unit stops the compressor to protect the unit from the frost. The control procedure for
indoor coil freeze protection.
1) The compressor and outdoor fan turn off.
2) Indoor fan operates according to user set speed.
3) The normal operation returns when the indoor coil
temperature is higher than 7°C or equal to 7°C.

3 Seconds Time Delay of Indoor Fan Motor
When the speed of indoor fan motor changes, there is a time delay of 3 seconds at each speed step.
Cooling Airflow Prevention
When the indoor coil temperature is lower than 37°C, Microcomputer of the unit stops indoor fan to prevent cooling
airflow.
Heating Airflow Prevention
When the indoor coil temperature is higher than 65°C, Microcomputer of the unit stops the compressor to prevent it
from overheating. In the funcfion of HEATING AIRFLOW PREVENTION, when pressing FAN SPEED button,
Remote controller received the signal, but the unit don’t operate.
After resetting the function of HEATING AIRFLOW PREVENTION, the unit operate by reveiving the signal.
Defrost Airflow Prevention
In HEAT mode, the defrpst is performed in the following conditions
–When the outdoor coil temperature is les than or equal to -5°C
–The compressor run time is greater than 45 minutes.
3 min. Time Delay of Compressor
In normal operation, there is a time delay of three minutes between turn off and turning back on including initial
power up.
