• According to the setting temperature selected by Fuzzy rule, the operating frequency of compressor is deter-

mined like heating mode operation.

• At the beginning of Fuzzy mode operation, the setting temperature is automatically selected according to the

intake air temperature at that time.

• When the Fuzzy key(=setting temp. key) is input after the initial setting temperature is selected, the Fuzzy key

value and intake air temperature at that time are compared to select the setting temperature automatically
according to the Fuzzy rule.

• While in Fuzzy operation, the airflow speed of the indoor fan is automatically operated by CHAOS logic.

• While  in heating mode or Fuzzy operation, the Jet Cool key cannot be input. When it is input while in the

other mode operation(cooling, dehumidification, ventilation), the Jet Cool mode is operated.

• In the Jet Cool mode, the indoor fan is operated super-high speed for 30 min. at cooling mode operation.
• In the Jet Cool mode, the room temperature is controlled to the setting temperature, 18°C.
• When the sleep timer mode input while the Jet Cool mode operation, the Jet Cool mode has the priority.
• When the Jet Cool key is input, the upper/lower vane is reset to those of the initial cooling mode and then

operated in order that the air outflow could reach further.

• By the Chaos swing key input, the upper/lower vane automatically operates with the Chaos swing or it is fixed

to the desired direction.

■

Do not have any heat or steam near the unit.

■

Select a place where there are no obstacles in
front of the unit.

■

Make sure that condensation drainage can be
conveniently routed away.

■

Do not install near a doorway.

■

Ensure that the space around the left and right of
the unit is more than 5cm. The unit should be
installed as high on the wall as possible, allowing
a minimum of 5cm from ceiling.

■

Use a stud finder to locate studs to prevent
unnecessary damage to the wall.

■

If an awning is built over the unit to prevent direct
sunlight or rain exposure, make sure that heat
radiation from the condenser is not restricted.

■

Ensure that the space around the back and sides
is more than 10cm. The front of the unit should
have more than 70cm of space.

■

Do not place animals and plants in the path of the
warm air.

■

Take the air conditioner weight into account and
select a place where noise and vibration are mini-
mum.

■

Select a place so that the warm air and noise
from the air conditioner do not disturb neighbors.

Install the indoor unit on the wall where the height
from the floors more than 2.3 meters.

* Both gas and liquid interconnecting pipes must be

insulated as a pair, but it is not necessary to individu-
ally insulate them.

• Capacity is based on standard length and maximum

allowance length is on the basis of reliability.

• Oil trap should be installed every 5~7 meters.

1) The earth line must connect to protect noise of EMI, EMS .
2) If it is not connect the earth line, It may occur safety problems.
3) If it crossed No1, No2 of fillet terminal, it must occur communication error (error code 5) but communication cir-

cuit is not malfunction.

4) The related earth line must be connected for EMC.
