orientation, the indoor room temperature, frequency of opening and closing door, insulation of building, height
of ceiling etc...
The common filter installed under the front frame at the factory can be reused after cleaning and drying.
To prevent accidents, make sure to install a fuse for the external power supply of the air conditioner. The fuse
should have a rated capacity of 15A. External power supply of the unit should be wired in accordance with the
related national standards. To prevent fire and accidents, extension cords should not be used.
The maximum input power and electric current specified on the label are values under the following extreme
O
circumstances: outdoor temperature of 43 C and voltage of 230V. Under normal circumstances, the output
power and electric current are approximately the values specified on the label.
Noise level specified on the label is the value measured in the Noise Measurement Room at the factory.
The water-proof level specified on the label is outdoor IPX4. The IXP4 test was conducted to the outside of
the air conditioner under the following conditions: the air conditioner is physically installed; the front cover of

Thermostat
When you adjust the thermostat to the desired
position, it will automatically control the
temperature of indoor air. The temperature of
the indoor air will become lower with each turn
clockwise.

Turbo Cool
Turn the function control switch to “TURBO Cool” then the unit automatically
conducts the high cool operation, so that the room temperature is reduced rapidly
and at the same time the room is being dehumidified and dust is being filtered.
Low Cool
Turn the function selector switch to “Low Cool” and the unit automatically
conducts calm cooling operation and eliminate dust from the room.
Thermostat Control
The thermostat is set by means of the THERMOSTAT control. When the room
temperature is higher than the thermostat setting, the compressor is
automatically switched on to provide a cooling effect. When the room
temperature is lower than the thermostat setting, the compressor is
automatically switched off to stop cooling.
It can be seen therefore, that the thermostat serves to keep the room
temperature constant by causing the compressor to start and stop
1. When you wish to lower the temperature, turn the THERMOSTAT
knob clockwise in the direction of the higher numbers on the dial.
2. When you wish to increase the temperature, turn the THERMOSTAT
knob counterclockwise in the direction of lower numbers on the dial.
