This air conditioner is a domestic electrical product of the class 1 anti-

shock protection category. The user should have grounding

equipment to ensure that the grounding terminal of the air

conditioner’s plug can be secured grounded, the method of power

connection in the air conditioner is M type connection.

This air conditioner fully utilizes water condensation. This improves

condensation effects and increases air cooling efficiency. Moreover,

we have adopted special noise reduction devices to reduce the noise

of water pumping.

The maximum input power and electric current marked on the label

are values under the most condition before the air conditioner left the

factory. The outdoor temperature was 43 C. But the input power and

electric current rating marked on the label were obtained from testes

conducted under conditions in which the outdoor temperature was

35 C and voltage was 220V.

The noise value marked on the label was obtained from tests

conducted in the Noise Measurement Room at the factory.

The water proof level marked on the label is outdoor IXP4. That is

where the air conditioner is in stated of actual installation, the front

cover and the wall is sealed. Under these conditions, the IXP4 test is

carried out on the outside unit of the air conditioner.

Note: If your air conditioner is the type that for cooling only, ignore the

instructions related to heating.

OPERATION MODES, FUNCTIONS

AND FEATURES

SLEEP Designed to create comfortable sleeping conditions. When in COOLING mode,

the temperature rises one degree centigrade every hour, for to three hours, from

the start of the mode. The temperature rise prevents the feeling of over-cooling

while sleeping (when your body is at rest). In HEATING mode the reverse occurs;

the air conditioner lowers its temperature one-degree every hour. When in SLEEP

mode, the air conditioner will be automatically turned off after have operated for

seven hours. The result is a more comfortable and invigorating sleep, which leaves

you feeling fresh and energetic on the next morning.

TIMER Real time control and display, automatically turns the air conditioner ON and

OFF according to the time of day setting, ensuring comfort conditions before

returning home, without wasting electricity. It turns the air conditioner off

automatically when sleeping.

HOT KEEP In HEATING and in AUTO FAN, the fan will be turned off when the compressor

is not in operation and will not be restarted, unless the indoor coil reaches

adequate temperature. The fan speed will vary automatically according to the

room temperature.

AUTO FAN The air conditioner automatically selects the FAN speed in accordance to with the

room temperature. At the start, the unit operates at high fan speed. As the room

air approaches to the desired temperature, the fan switches to a lower speed for

quieter operation.

FAN Recirculates and filters the room air. Maintains constant air movement in

the room.

DRY Dehumidifies and softly cools the room In DRY Mode, the air conditioner

operates at an inceased dehumidifying power. This function is recommended

to be used when temperature is rather low but the humidity is high.
