3. Installation and Operating Instructions  
3-1 Installation  
3-1-1 Selecting Area for Installation  
1. Make sure that you install the unit in an area  
providing good ventilation. The air conditioner  
must not be blocked by any obstacle affecting the  
air flow near the air inlet and air outlet.  
6. Make sure that you install the unit in an area  
which provides easy drainage for condensed  
water.  
7. Make sure that you install the unit in an area not  
exposed to rain or direct sunlight.  
(Install a separate sunblind if exposed to direct  
sunlight.)  
2. Make sure that you install the unit in an area that  
allow good air handling. The installation area  
must be able to endure vibration from the unit.  
3. Make sure that you install the unit away from  
heat or vapor.  
8. Make sure that you install the unit in an area  
allowing good air movement. Do not install it in  
a space that would cause noise amplification of  
noise.  
4. Make sure that you install the unit in an area  
which is cool and has adequate space.  
9. Fix the unit firmly if mounted in a high place.  
5. Make sure that you install the unit in an area  
away from TVs, audio units, cordless phones,  
fluorescent lighting fixtures and other electrical  
appliances (obtain a clearance of at least one  
meter).  
Ca u t io n :  
Do not use the air conditioner in the following environm ents : greasy areas (including areas near  
m achines), or m arine areas. Contact your local dealer for advice.

• Compressor on and off control according to the ambient temperature  
The compressor is turned off when "ambient temperature = set temperature  
The compressor is turned on when "ambient temperature = set temperature +1˚C"  
2) Default value after power reset set temperature = 75˚F  
Fan speed = High  
*
*
3) Set temperature indicating (setting) range : 1˚F interval from 64˚F to 86˚F.  
3-2-2 Fan operation mode  
1) If "Fan operation mode" signal is received from remocon or panel.  
➔➔ the compressor is immediately turned off and only fan motor is operated at set blowing speed.  
➔➔ it changes such as "High Med Low High"( if Fan speed is selected).  
2) The initial Fan motor speed is set to "High".  
3) The set temperature can not be indicated and set.  
3-2-3 Energy saver operation mode  
If the compressor turn off at the cooling operation, the fan motor turn off after operation during the fixation  
*
time only, and operation that energy saver by turn off the fixation time only, and operation that energy saver  
by turn off the motor continuously before the condition of the compressor on.  
The fan motor is not operated at flow wind operation.  
Energy saver operation specification at the cooling operation.  
*
*
1) Fan motor control in compressor on : operate with setting wind speed  
2) Fan motor control in compressor off : After compressor off, the fan motor is operated breeze for 2 minutes  
and then it turn off.  
3) After the fan motor off, the compressor and fan motor is operated normally when the compressor on.

3-2-4 Sleep operation mode  
1) Enable to sleep operation only when cooling operation.  
2) First, 7-SEG LED DISPLAY "SLEEP" while 15 second, Second, 7-SEG LED DISPLAY "8Hr"  
And, automatically SET OFF after operated while 8 Hour  
3) If sleep operation, setting Temperature rise 1˚C after 1 Hour  
4) ON TIMER operation, not operation, ENERGY SAVER operation, not sleep operation.

5. Troubleshooting  
Check the basic checkpoints first to determine whether it is machine trouble or a problem  
in the operation method. When it is not related to the basic checkpoints, perform checking  
in accordance with the procedures of troubleshooting by symptom.  
5-1 Basic Checkpoints for Troubleshooting  
1) Is the voltage of the power source appropriate ?  
(1) It should be within the rating voltage ±10% range.  
(2) The air conditioner may not operate properly when the voltage is out of this range.  
2) Is the connection with the fan motor, compressor wire, and starting condenser  
appropriately made ?  
3) The symptoms listed in the table below are not indicative of machine trouble.  
Symptom  
Cause and check  
No operation  
• Check whether there is power failure or the power plug is pulled out.  
• Check whether the unit is stopped as a result of completion  
of the sleep time.  
• Pull out the power plug for ten seconds, and then insert it again.  
Air flows, but  
no cooling  
• Check whether the Air filter is clogged with dust or is dirty.  
• Check whether the desired temperature is too high. Set the desired  
temperature to a lower level than the current temperature.  
• Check whether it is in "FAN" mode.  
The remocon does  
not operate  
• Check whether battery is completely depleted.  
• Check whether the battery is properly inserted.  
• Check whether the receiving window of the remocon for the assembly  
main PCB is blinded.  
• Check whether the remocon is affected by jamming due to a neon sign.  
No temperature  
setting  
• Check whether the unit is in "FAN" mode.  
(In "FAN" mode, only the current temperature is displayed, and the  
desired temperature is not set.)
