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.  
Do not turn the air conditioner on and off from the power mains  
switch. Use the ON/OFF operation button.  
CAUTION  
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 or heat the room too much if babies or invalids are  
present.

Special Remarks  
‘‘DRY’’ ( ) Operation  
How it works?  
Once the room temperature reaches the level that was set, the unit’s  
operation frequency is changed automatically.  
During DRY operation, the fan speed is automatically runs at lower speed  
for providing a comfortable breeze.  
‘‘DRY’’ operation is not possible if the indoor temperature is 15 °C or less.  
Heating ( ) Operation  
Heating performance  
Because this air conditioner heats a room by drawing in the heat of the  
outside air (heat pump system), the heating efficiency will fall off when the  
outdoor temperature is very low. If sufficient heat cannot be obtained with  
this air conditioner, use another heating appliance together with it.  
Defrosting  
When the outdoor temperature is low, frost or ice may form on the heat  
exchanger coil, reducing heating performance. When this happens, a  
microcomputer defrosting system operates. At the same time, the fan on  
the indoor unit stops and the OPERATION lamp lights up red and orange  
alternately until defrosting is completed. Heating operation restarts after  
several minutes. (This interval will vary slightly depending upon the  
outdoor temperature and the way in which frost forms.)  
Cold draft prevention  
For several minutes after the start of heating operation, the indoor fan runs  
at lower speed until the indoor heat exchanger coil has warmed up  
sufficiently. However, the fan may remain stopped when the room  
temperature is low. This is because the COLD DRAFT PREVENTION  
SYSTEM is operating.  
In the event of power failure, the unit will stop. When the power is  
resumed, the unit will restart automatically within five minutes by the  
remote control unit.  
Power failure during  
operation  
Clicking Sound  
Clicking sound is heard from  
the air conditioner  
In heating or cooling 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.

Tips for Energy Saving  
Do not  
Block the air intake and outlet of the unit. If they are obstructed, the  
unit will not work well, and may be damaged.  
Let direct sunlight into the room. Use sunshades, blinds or curtains. If the  
walls and ceiling of the room are warmed by the sun, it will take longer to  
cool the room.  
Do  
Always try to keep the air filter clean. (Refer to “Care and Cleaning”.) A  
clogged filter will impair the performance of the unit.  
To prevent conditioned air from escaping, keep windows, doors and any  
other openings closed.

NOTE  
During the heating operation, the fan speed will be very low and the flap  
will be in the horizontal position (position ) until the air being blown out  
of the unit begins to warm. Once the air warms up, the flap position and  
fan speed change to the settings specified with the remote control.  
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.
