| Q | The cooling is weak. | |
|
|
| |
| A | 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. | |
|
|
| |
| 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 | |
|
| So, set up a sunblind over the outdoor unit and keep stuff away from the unit to increase the ventila | |
|
| tion. When the cooling capacity decreases during a heat wave, clean the heat exchanger of the out | |
|
| door unit or spray some cold water to the heat exchanger to increase the cooling capability. | |
Cooling |
|
| |
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. | |
|
|
| |
| Q | It fails to do cooling. | |
|
|
| |
| A | 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. | |
|
|
| |
| Q | It floods the floor. | |
|
|
| |
| A | 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. | |
|
|
| |
| Q | Water drips at the drain connection (service valve) of the outdoor unit. | |
|
|
| |
| A | 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 | |
Leakage |
| 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. | |
|
|
| |
| Q | It leaks even though a drain pump is used. | |
|
|
| |
| A | 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. | |
|
|
| |
| A | There are no components in the air conditioner irritating the eyes and sending out chemical smells. | |
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 | |
