Is the line cable linking the indoor unit and the outdoor unit linked properly? The indoor unit and the outdoor unit shall be linked by 5 cables. Check the terminals if the indoor unit and outdoor unit are properly linked by the same number of cables. Otherwise the air conditioner may not operate properly. 3. When a problem occurs due to the contents illustrated in the table below it is a symptom not related to the malfunction of the air conditioner. Operation of air conditioner Explanation 2 The OPERATION indication LED(BLUE) blinks when a power plug of the indoor unit is plugged in for first time. In a COOL operation mode, the compressor does not operate at a room temperature higher than the setting temperature that the INDOOR FAN should operate. [ In case of heat pump model ] In a HEAT operation mode, the compressor does not operate at a room temperature lower than the setting temperature that indoor fan should operate. It indicates power is on. The LED stops blinking if the operation ON/OFF button on the remote control unit is pushed. In happens after a delay of 3 minutes when the compressor is reoperated. The same phenomenon occurs when a power is on. As a phenomenon that the compressor is reoperated after a delay of 3 minutes, the indoor fan is adjusted automatically with reference to a temperature of the air blew. 3 Fan speed setting is not allowed in DRY mode. The speed of the indoor fan is set to LL in DRY mode. Fan speed is selected automatically in AUTO mode Compressor stops operation intermittently in Dry mode. Timer LED(ORANGE) of the indoor unit lights up and the air conditioner does not operate. The compressor stops intermittently in a COOL mode or DRY mode, and fan speed of the indoor unit decreases. [In case of heat pump model] Compressor of the outdoor unit is operating although it is turned off in a HEAT mode. [In case of heat pump model] The compressor and indoor fan stop intermittenly in HEAT mode. [In case of heat pump model] Indoor fan and outdoor fan stop operation intermittently in a HEAT mode. Compressor operation is controlled automatically in DRY mode depending on the room temperature and humidity. Timer is being activated and the unit is in ready mode. The unit operates normally if the timer operation is cancelled. The compressor stops intermittently or the fan speed of the indoor unit decreases to prevent inside/outside air frozen depending on the inside/outside air temperature. When the unit is turned off while de-ice is activated, the compressor continus operation for up to 9 minutes(maximum) until the deice is completed. The compressor and indoor fan stop intermittently if room temperature exceeds a setting temperature in order to protect the compressor from overheated air in a HEAT mode. The compressor operates in a reverse cycle to remove exterior ice in a HEAT mode, and indoor fan and outdoor fan do not operate intermittently for within 20% of the total heater operation.

101 2-3 Q & A for Non-trouble Classification Class Description Q A The cooling is weak. When it is hot outside, its cooling capacity decreases due to the increase of the ambient temperature. When the dust filter gets blocked or warm outside air gets in, the cooling capacity will decrease. So, make sure to clean the dust filter frequently, prevent heat loss by closing the doors and insulate the cooling area by using curtains, blinds, shades or window tinting. Cooling Q The cooling is good generally. But, it gets weak when it is considerably hot. A It occurs when the outdoor unit is exposed to direct sun light and heat-up air is not ventilated well. So, set up a sunblind over the outdoor unit and keep stuff away from the unit to increase the ventilation. When the cooling capacity decreases during a heat wave, clean the heat exchanger of the outdoor unit or spray some cold water to the heat exchanger to increase the cooling capability. Q The cooling is weak. Does it need refrigerant charging? A It is not correct charging refrigerant regularly. Except that you have moved in several times or the connection pipes are broken, the refrigerant does not run low. So, when refrigerant is additionally charged, it could be costly and cause a product's failure. When the refrigerant leaks, all of it will escape in a short time resulting in cooling failure and no water coming out of the drain hose. So, if water comes out from the drain hose, it indicates the normal operation of the product and it does not need refrigerant charging. Leakage Q A Q A Q A Q A It fails to do cooling. When the air conditioner is set to ventilation or the desired temperature is set higher than the current temperature, it fails to do cooling. In this case, select cooling or set the desired temperature lower. It floods the floor. Place the drain hose properly. When it is not placed properly, the drain water would flow back flooding the floor. So, straighten out the drain hose for the water to be drained well. Water drips at the drain connection (service valve) of the outdoor unit. When a glass bottle is taken out of the refrigerator, moisture gets condensed on its surface due to the temperature differences. The same principle applies to the air conditioner. When cold refrigerant goes through the copper tube, moisture gets condensed on the surface of the tube and the connection areas. To prevent the water condensation, the pipes are insulated. But, the connection areas of the outdoor unit are not insulated for the purpose of maintenance or repair, and water gets condensed due to the temperature differences and drips down. Generally, it evaporates right away. But, when it drips much during muggy days, put a water pan on the floor. It leaks even though a drain pump is used. It occurs when the drain pump is plugged out or it is out of order. Check the power of the drain pump and the position of the drain hose, and when the pump is faulty, contact the drain pump manufacturer. Samsung Electronics do not manufacture drain pumps. So, we are not able to correct the drain pump problems. Q Whenever the air conditioner is turned on, it irritates my eyes and gives me a headache. Smells A There are no components in the air conditioner irritating the eyes and sending out chemical smells. But, when the air conditioner is turned on, other smell sources are sucked into the air conditioner and get out of it. So find and root out the smell sources. Generally, it occurs at a interior renovated place, a pharmacy, a gasoline handling place, a tire shop, a second-hand book shop or an electronic component handling place, when its chemical or musty smells are sucked in and sent out, it can be misled that the air conditioner generates them. 2-2 Samsung Electronics

102 Classification Class Description Q Whenever the air conditioner is turned on, it stinks. Smells Operation A Q A Q A Q A Q A Q A Q A Q A Q When are no components in the air conditioner sending out chemical smells. But, when the air conditioner is turned on, other smell sources are sucked into the air conditioner and get out of it. So, find and root out the smell sources. Generally, when the drain hose is taken out to the washing room or there are sources of smells such as a diaper bin, a shoe shelf or a socks bin, bad smells generate. Also, it occurs where glass cleaners or air fresheners are used; when they are sucked in interacting with dusts and moistures inside, bad smells generate. these kinds of organic materials noxious to human bodies. So, we recommend against the use of them. Whenever the air conditioner is turned on, it smells sour. When the room is papered recently, its paste smells would be sucked inside. Also, when the air conditioner is installed in the study room of young boys loving sweat-generating activities such as the basketball, excessive sweats evaporate and get sucked into the air conditioner resulting in bad smells. So, find and root out problem or refresh the room frequently. Whenever the air conditioner is turned on, it smells musty. It is due to the improper keeping of the product after its use. When keeping the product, dry up the inside with the operation of ventilation to prevent must. When the product is kept without drying up the inside with ventilation, mold would grow inside resulting in must.
