As the temperature of the outside air drops, the heating performance of air   conditioner will decrease. If you find that the room is not warm enough, using an additional   heating appliance is recommended.   Warm air circulation   The air conditioner circulates warm air to heat your room. It will take some time to warm the   air in your room entirely after the air conditioner turns on. Therefore, turn the air conditioner on   in advance.   Frost   When outdoor temperature is low but humidity is high, frost may form on the outdoor unit at   Heat mode.   The heating operation stops.   The defrost mode will be triggered automatically for 3 to 14 minutes.   No intervention is required ; after about 7 minutes, the air conditioner operates again normally.   High indoor and   If both indoor and outdoor temperatures are high and the air conditioner is running at HEAT   outdoor temperatures mode, the outdoor unit’s fan and compressor may stop at times. This is normal;simply wait until   the air conditioner switches on again.   Power failure   If a power failure occurs while the air conditioner is operating, the unit will be switched off.   When the power returns, the air conditioner starts up again automatically.   Protection mechanism When the air conditioner is started immediately after being plugged in or stopped, the normal   operation starts up after 3 minutes for the reason of protection.   Cooling operation   Silence Mode   The indoor unit may not get the selected fan speed such as Medium and Low under cooling   operation at very low outdoor temperatures for the protection of the indoor unit from ice   or frost.   During Low fan speed operation, cooling performance will be reduced. If the room does not be   cooled down when using Low fan speed operation, please adjust the indoor unit’s fan speed.   When you operate Silence Mode in cooling and heating, fan speed will decrease to make noise   quieter.   As a result, the performance of the unit may be reduced.   E-22   Temperature and Humidity Ranges   If you check the following tables, you can use your air conditioner more efficiently.   If the air conditioner is used at... Then...   Heating capacity   Low temperatures   The air conditioner may stop operating for the reason of protection.   Water may leak and some malfunction may occur if the heat exchanger freezes.   Water may condense and drip from the surface of the indoor unit if you don’t use   the air conditioner for an extended period of time.   Protection mechanism   Operation   Outdoor Temperature   Indoor Temperature   Indoor Humidity   5°F to 75°F approx.   80°F or less   27°C or less   61°F to 90°F approx.   16°C to 32°C approx.   61°F to 90°F approx.   16°C to 32°C approx.   Heating   - -15°C to 24°C approx.   14°F to 109°F approx.   -10°C to 43°C approx.   14°F to 109°F approx.   -10°C to 43°C approx.   Cooling   80% or less   - Dehumidifying    If the outdoor temperature is as low as 32°F/0°C, the heating capacity drops up to 70~80% depending on   the operating condition.   If you use the air conditioner in temperatures over 90°F/32°C (indoor temperature), the cooling capacity may drop.   Operating Your Air Conditioner Without the Remote Control   You can operate your air conditioner directly without the remote   control.   1 To turn the air conditioner on, press the On/Off button on the right side of   the indoor unit.   Result:      The Operation indicator on the indoor unit lights up.   The indoor unit beeps.   The air conditioner starts up in the appropriate mode for   the room temperature. The air conditioner changes the Cool or   Heat mode automatically depending on the current   temperature during operation.   2 To turn the air conditioner off, press the On/Off button again.   Note   Even if you turned the air conditioner on with the On/Off button,   you can control it with the remote control.   E-23   Troubleshooting Guide   Before contacting the after-sales service, perform the following simple checks.   They may save you the time and expense of an unnecessary call.   Problem   Explanation/Solution   The air conditioner does not   operate at all.      Check if power is on and operate the air conditioner again.   Check if the circuit breaker is switched off.   Check if Off Timer is set.   The temperature is not adjusted.    Check if you selected the Fan mode.   The air conditioner does not operate   in the HEAT mode.     Check if the air conditioner is cooling only model.   Check if the remote control is for cooling only model.   The cool(warm) air does not come   out from the air conditioner.     Check if set temperature higher(lower) than current temperature.   Check if you selected the Fan mode. Select the Cool, Heat, Auto or Dry   mode.     Check if the air filter is blocked by dirt. Clean the air filter regularly.   Check if the there is cover on the outdoor unit or any obstacle.   Remove the cover or obstacle.      Check if you installed the air conditioner under direct sunlight.   The window or door may be opened.   Check if you turn on the air conditioner just now.   It takes about 3 minutes to cool or heat the room.   Check if the drain pipe is too long.     The fan speed is not adjusted.   In Dry mode, the fan speed is selected automatically.   The remote control does   not operate.      Check if the battery is discharged. Replace the battery.   Check if the remote control sensor is blocked.   Check if the air conditioner is placed near strong light.   The Timer is not set.     Check if you pressed the   button after selecting time.   Odor is permeated in the   room during operation.   Check if you use the air conditioner in smoky area or there is a smell.   Ventilate the room or select the Fan mode for 1~2 hours.   The indoor unit indicator   flashes.    Press the   button to turn on the air conditioner again.   Switch the circuit breaker off and switch on it again.   Strange sound is heard from   the air conditioner.     The sound is heard when the refrigerant gas flow is changed depending   on the use of the air conditioner.   When you press the   button, noise may be heard that the   air conditioner sense the airflow blade.   Water drops from the outdoor   unit connection part.    Water may form due to the difference of the temperature.   E-24   Cleaning Your Air Conditioner   To get the best possible use out of your air conditioner, you must   clean it regularly to remove the dust that accumulates on the air filter.   Before cleaning your air conditioner, ensure that you   have switched off the breaker used for the unit.   IMPORTANT   Open the upper front grille by pulling the lower right and left tabs   of the grille.   1 2 3 4 5 Pull air filters out of each tab of the grille.   Remove all dust on the air filters with a vacuum cleaner or brush.   When you finished, insert air filters by fixing it to each tab of the grille.   Front grille   Air filter   To close the front grille, fix it to hooks and push down the lower   right and left tabs of the grille.   Body groove   Body   Clean the front grille with a damp cloth and mild detergent   (do NOT use benzene, solvents or other chemicals).   6 Front grille   Hook   Note   If you have not used the air conditioner for a long period of time,   set the fan going for three to four hours to dry the inside of   the air conditioner thoroughly.   Body   Cleaning Deodorizing and Bio filter (Option)   To remove minute dust particles and odors, deodorizing and Bio filter   are installed in the air conditioner.
