Installation Location  
We recommend that this air conditioner be installed properly by  
qualified installation technicians in accordance with the Installation  
Instructions provided with the unit.  
Before installation, check that the voltage of the electric supply in your  
home or office is the same as the voltage shown on the nameplate.  
Do not install this air conditioner where there are fumes or flammable  
gases, or in an extremely humid space such as a greenhouse.  
Do not install the air conditioner where excessively high heat-  
generating objects are placed.  
Avoid:  
To protect the air conditioner from heavy corrosion, avoid installing the  
outdoor unit where salty sea water can splash directly onto it or in  
sulphurous air near a spa.  
Electrical Requirements  
1. All wiring must conform to the local electrical codes. Consult your  
dealer or a qualified electrician for details.  
2. Each unit must be properly grounded with a ground (or earth) wire or  
through the supply wiring.  
3. Wiring must be done by a qualified electrician.  
Safety Instructions  
Read this Instruction Manual carefully before using this air conditioner.  
If you still have any difficulties or problems, consult your dealer for  
help.  
This air conditioner is designed to give you comfortable room  
conditions. Use this only for its intended purpose as described in this  
Instruction Manual.  
Never use or store gasoline or other flammable vapor or liquid near  
the air conditioner — it is very dangerous.  
This air conditioner has no ventilator for intaking fresh air from  
outdoors. You must open doors or windows frequently when you use  
gas or oil heating appliances in the same room, which  
consume a lot of oxygen from the air. Otherwise there is a risk of  
suffocation in an extreme case.  
CAUTION  
Do not turn the air conditioner on and off from the power mains  
switch. Use the ON/OFF operation button.  
Do not stick anything into the air outlet of the outdoor unit. This is  
dangerous because the fan is rotating at high speed.  
Do not let children play with the air conditioner.  
Do not cool the room too much if babies or invalids are present.

Normally, the address switch is set to A. When switching the address, the  
remote control must be changed, and the jumper cables on the indoor unit  
board must be cut. For more information, please contact the dealer where  
you made the purchase.  
Normally, the tabs on the remote control unit should not be bent.  
SENSOR button When you press this button (use a small-tipped object such as a ballpoint  
pen), the mark will appear at the display. And the room temperature is  
detected by the sensor which is built into the indoor unit and the air  
conditioner is controlled accordingly.  
NOTE If the remote control is located near a heat source, such as a space heater or  
in direct sunlight, press the SENSOR button to switch to the sensor on the  
indoor unit.  
NOTE The remote control unit sends the temperature signal to the air conditioner regularly at five minute intervals.  
If the signal from the remote control unit stops for more than ten minutes due to the loss of the remote  
control unit or other trouble, the air conditioner will switch to the temperature sensor which is built into  
the indoor unit and control the room temperature. In these cases, the temperature around the remote  
control unit may differ from the temperature detected at the air conditioners position.

Special Remarks  
‘‘DRY’’ ( ) Operation  
How it works?  
Once the room temperature reaches the level that was set, the unit  
repeats the cycle of turning on and off automatically.  
During DRY operation, the fan speed is automatically set to LOW or  
VERY LOW; the fan speed then switches back and forth between LOW  
(for 20 seconds) and VERY LOW (for 10 seconds).  
‘‘DRY’’ operation is not possible if the indoor temperature is 59 °F or  
less.  
In the event of power failure, the unit will stop. When the power is  
turned on again, the unit restarts within five minutes.

Clicking Sound  
Clicking sound is  
heard from the air

In cooling and drying operation, any plastic parts may expand or shrink  
due to a sudden temperature change. In this event, a clicking sound  
may occur. This is normal, and the sound will soon disappear.  
The remote control unit sends the setting condition to the air  
conditioner regularly at five minute intervals.

Adjusting the Airflow Direction  
1. Horizontal  
The horizontal airflow can be adjusted by moving the vertical vanes with your  
hands to the left or right.  
CAUTION  
2.Vertical  
When the humidity is high, the vertical vanes should be in the front  
position during the cooling or drying operation. If the vertical vanes  
are positioned all the way to the right or left, condensation may begin  
to form around the air vent and drip down.  
The vertical airflow can be adjusted by moving the flap with the remote  
control unit. Do not move the flap with your hands. Confirm that the remote  
control unit has been turned on. Use the FLAP button to set either the  
sweep function or one of the six airflow direction settings.

the cooling or drying operation.  
NOTE  
The flap automatically closes when the unit is off.  
CAUTION  
Use the FLAP button on the remote control to adjust the position of the flap.  
If you move the flap by hand, the flap position according to the remote control  
and the actual flap position may no longer match. If this should happen, shut  
off the unit, wait for the flap to close, and then turn on the unit again; the flap  
position will now be normal again.  
Do not have the flap pointed down during cooling operation.  
Condensation may begin to form around the air vent and drip down.

Care and Cleaning  
1. For safety, be sure to turn the air conditioner off and also to disconnect  
the power before cleaning.  
WARNING  
2. Do not pour water on the indoor unit to clean it.This will damage the  
internal components and cause an electric shock hazard.  
Casing and Grille  
(Indoor Unit)  
Clean the casing and grille of the indoor unit with a vacuum cleaner brush,  
or wipe them with a clean, soft cloth.  
If these parts are stained, use a clean cloth moistened with a mild liquid  
detergent. When cleaning the grille, be careful not to force the vanes out of  
place.  
1. Never use solvents, or harsh chemicals when cleaning the indoor unit.  
Do not wipe the plastic casing using very hot water.  
CAUTION  
2. Some metal edges and the fins are sharp and may cause injury if handled  
improperly; be especially careful when you clean these parts.  
3. The internal coil and other components of the outdoor unit must be  
cleaned every year. Consult your dealer or service center.
