Using your air conditioner
Tips on using air conditioner
Here are some tips that you would follow when using your air conditioner.
TOPIC RECOMMENDATION
Cooling
•If current outside temperatures are much higher than
the selected indoor temperature, it may take time to
bring the inner temperature to the desired coolness.
•Avoid drastically turning down the temperature.
Energy is wasted and the room does not cool faster.
Heating
•Since the air conditioner heats the room by taking
heat energy from outdoor air, the heating capacity
may decrease when outdoor temperatures are
extremely low. If you feel the air conditioner
insufficiently heats, using an additional heating
appliance in combination with the air conditioner is
recommended.
De-ice mode
•When the air conditioner runs in Heat mode, due to
temperature difference between the unit and the
outside air, frost will form.
If this happens:
- The air conditioner stops heating.
- The air conditioner will operate automatically in De-
ice mode for 10 minutes.
- The steam produced on the outdoor unit in De-ice
mode is safe.

19
ENGLISH
TOPIC RECOMMENDATION
De-ice
No intervention is required; after about 10 minutes, the
air conditioner operates again normally.
•The unit will not operate when it starts to
de-ice.
NOTE
Fan
•Fan may not operate for about 3~5 minutes at the
beginning to prevent any cold blasts while the air
conditioner is warming up.
High indoor/
outdoor
temperatures
•If both indoor and outdoor temperatures are high
and the air conditioner is running in Heat mode, the
outdoor unit’s fan and compressor may stop at times.
This is normal; wait until the air conditioner turns on
again.
Power failure
•If a power failure occurs during the operation of the
air conditioner, the operating immediately stops
and unit will be off. When power returns, the air
conditioner will run automatically.
Protection
mechanism
•If the air conditioner has just been turned on after
operation stops or being plugged in, cool/warm
air does not come out for 3 minutes to protect the
compressor of the outdoor unit.

20
Cleaning and maintaining the air conditioner
For the best performance of your air conditioner, clean it periodically. When
When cleaning, make sure to disconnect power for user’s safety.
Cleaning the exterior
Wipe the surface of the unit with a slightly wet or dry cloth when needed.
Wipe off dirt of odd-shaped area by using a soft brush.
•Do not use Benzene or Thinner. They
may damage the surface of the air
conditioner and can create a risk of fire.
CAUTION
Cleaning air lter and grille
When cleaning air filter and grille, make sure to unplug the unit. No special
tools are needed to clean it.
1. Open the front grille.
• Open the blades on the left and right side of the Samsung
logo. Press both of the levers and pull the grille downward.
Two safety clips are mounted to the front grille to prevent
it from dropping.
2. Detach the front grille.
• Remove the safety clip first and then remove the hinge.
Pull the green switch on the hinge part down and then
press and pull the hinge part to remove the grille. There are
two hinges on the grille and you must apply this step on
both of them to remove the grille.
• If you want to clean the filter only, you do not have to detach the grille. Follow step 4 and 5
