Features of your new air conditioner
Contents
Environment-friendly air conditioner
Your environment-friendly air conditioner has achieved not
only high efficiency, low noise, and energy saving technol-
ogy but also certified RoHS technology.
Energy saving technology with S-inverter system
The S-inverter system that changes the capacity of the
air conditioner from 10% to 160% with one compressor
depending on the usage condition will provide optimal
cooling performance with less energy consumption by
reducing unnecessary electric consumption.
Powerful speed/Convenient remote operation
The speed operation will provide you with quick cooling and
heating for 30min and the remote operation will provide
you with cooling even for remote area.
(Heating operation applicable model: AP-SM

2 Series)
High efficiency purifying function for four seasons
Since the purifying function can operate separately, the
energy consumption and operation noise can be further
reduced. When operating the air conditioner, the virus
doctor function works continuously using a sterilization
function that removes harmful substances from the air
and a neutralizing active oxygen function that will provide
you with a healthy and clean environment.
Auto air flow blades
The auto air flow blade that opens and closes according to
the on or off operation of the air conditioner increases the
usage convenience and it also prevent dust from coming
into the air conditioner when the air conditioner is not used
for a long term.

Checking before use
Using indoor unit Using outdoor unit
Storing indoor unit
Make sure that curtain does not block the air inlet.
It may decrease cooling or heating performance by
blocking air circulation.
In Cool mode, set the appropriate desired temperature.
I
f the desired temperature is too low, it may be harmful
for human body and power consumption will also
increase. Set the desired temperature about 5˚C lower
han the outdoor temperature.
Use extra heating apparatus during heat mode.
Heating performance of the air conditioner may
decrease when the indoor/outdoor temperature
drops therefore, use extra heating apparatus.
(Model : AP-SM

2 Series)
When cooling the room, use air conditioner and fan
together to save energy.
When the air conditioner is used with fan, cooling will
be more effective and energy can be saved.
When the air conditioner is operating, close the doors
and windows.
▶
When the air conditioner is used with doors and
windows open, cooling(or heating) effect will
decrease.
If you use the air conditioner for over an hour, open the
window to ventilate the air about once every hour.
Install the product away from sunlight or heating
devices.
Close the curtain when the sun shines.
Do not use any heating devices during cooling
operation. Cooling effect will decrease.
Take away any covers or barriers.
It may cause product failure, and poor performance
in cooling (heating) by blocking air flow.
Installing outdoor unit
Install the outdoor unit in well ventilated area with no
sunlight. If sunlight is unavoidable, install a sunshade.
Dry the air conditioner thoroughly by operating
Fan mode for 3 to 4 hours.
Stop the operation and disconnect the power plug
.
Turn on the auxiliary power switch which is installed
separately.

may get loose or pipe can get damaged and
cause refrigerant leakage.
CAUTION
Auxiliary power switch(ELCB, ELB)
Auxiliary power switch is not included in the
package. Purchase and install it separately.
Auxiliary power switch is a device for

When the air conditioner operates outside of temperature and humidity range indicated below, protective
device may activate and stop the operation. Especially, when installing and performing the trial operation
of the air conditioner in the winter, start the operation 1 hour after you supply power to the unit. Product
malfunction may occur due to the drastic temperature difference between indoor and outdoor room.
If the air conditioner operates in cooling mode for long period of time in high humidity area, dew may
be formed.
When the outdoor temperature goes down to -15
, the heating capacity may decrease to 70%~80%
according to the usage condition.

What is heat pump?
Heat pump can raise heat from low temperature to high temperature. It also warms the indoor room further by
absorbing heat from outdoor room in the winter and providing the heat to indoor room.
If the outdoor or indoor temperature is lower than the rated temperature(Indoor-20
, outdoor-7
) or the installation
condition is different(the length of pipe is longer than 5m, installation place and insulation), the heating capacity may
decrease even though the air conditioner performs normal operation.
If the outdoor temperature goes below zero temperatures during the heat mode in the winter, the air conditioner itself
automatically performs protective operation. When disconnecting power from the product, the protection function for
the compressor may not operate and it will cause the product malfunction. Therefore, do not disconnect power of the
product in the winter.
