12-3 Q & A for Non-trouble
Classification Class Description
Cooling
QThe cooling is weak.
AWhen it is hot outside, its cooling capacity decreases due to the increase of the ambient temperature.
When the dust fil
ter 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.
QThe 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 cool
ing 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 ru
n 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.
QIt fails to do cooli
ng.
AWhen 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
QIt floods the floor.
APlace the drain hose properly. When it is not placed properly, the drain water would flow back flooding
the floor. So, straighten out th
e drain hose for the water to be drained well.
QWater drips at the drain connection (service valve) of the outdoor unit.
AWhen a glass bottle is taken out of the refrigerator, moistu
re 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 th
e 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 o
f 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 fl
oor.
QIt 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 th
e 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. G
enerally, 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 mu
sty smells are sucked in and sent out, it can be misled that the
air conditioner generates them.
