Description
Cooling
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 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.
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.
Leakage
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 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.
Smells
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.
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. So, find and root out the problem or refresh the room frequently.
