Caution Statements  
1.We recommend that this air conditioner be installed properly by  
qualified installation technicians in accordance with the installation  
instructions provided with the unit.  
WARNING  
2.Before installation, check if the voltage of the electric supply in your  
home or office is the same as the voltage shown on the nameplate.  
WARNING  
3.Do not install the air conditioner where there are fumes or flammable  
gases, or in an extremely humid space such as a greenhouse.  
4.Do not install the air conditioner where excessively high heat-  
generating objects are placed.  
To protect the air conditioner from heavy corrosion, avoid installing the outdoor  
Avoid:  
unit where salty sea water can splash directly onto it or in sulphurous air near a  
spa.  
1.All wiring must conform to the local electrical codes.  
2.Each unit must be properly grounded.  
3.Wiring must be done by a qualified electrician.  
4.Consider the capacity of the electric current of your electrical kilowatt-  
hour meter wires and socket before installation.  
5.Power for this air-conditioner is supplied by individual electrical wire.  
6.There must be at least one ventilation intake in the area where the  
heat-pump is mounted.  
1.Read this manual carefully before using this air conditioner. If you still have  
any diffculties or problems, consult your dealer for help.  
2.The air conditioner is designed to give you comfortable room conditions.  
Use this only for its intended purpose as described in this instruction  
manual.  
WARNING  
3.Never use store gasoline or other flammable vapor or liquid near the  
air conditioner - it is very dangerous.  
4.The 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.  
1.Do not turn the air conditioner on and off from the power mains  
switch. Use the ON/OFF operation button.  
CAUTION  
2.Do not stick anything into the air outlet of the outdoor unit. This is  
dangerous because the fan is rotating at high speed.  
3.Do not let the children play with the air conditioner.  
4.Do not cool or heat the room too much if babies or invailds are  
present.

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.  
If the remote control is located near a heat source, such as a space heater or  
indirect sunlight, press the A/C SENSOR button to switch to the sensor in the  
indoor unit.  
NOTE  
!
Automatic switching between cooling and heating  
This unit automatically switches between cooling operation and heating operation according to the difference  
between the room temperature and the set temperature.  
The remote control unit sends the temperature signal to the air conditioner regularly at three  
NOTE  
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 conditioner,s position.

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.  
When the humidity is high, the vertical vanes should be in the front  
position during the cooling or dehumidifying operation. If the vertical  
vanes are positioned all of the way to the right or left, condensation may  
begin to form around the air vent and drip down.  
CAUTION  
!
2. Vertical  
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.  
Then, use the FLAP button to set either the sweep function or one of  
thesixairflowdirectionsettings.

Special Remarks  
Heating (  
) Operation  
Heating performance  
Because this air conditioner heats a room by drawing on 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 in conjunction with it.  
When the outdoor temperature is low, frost or ice may from in the heat exchanger  
coil, reducing heating performance. When this happens, a microcomputer defrosting  
system will operate. At the same time the fan on the indoor unit stops ( or runs at  
very low speed in some cases). Heating operation restarts after several minutes.  
(This interval will vary slightly depending upon the outdoor temperature and the way  
in which frost forms).  
Defrosting  
POWER lamp  
For several minutes after the start of heating operation, the indoor fan will not start  
running until the indoor heat exchanger coil has warmed up sufficiently. This is  
because the COLD DRAFT PREVENTION SYSTEM is operating.  
The POWER lamp also remains lit during defrosting or when the compressor has  
been turned off by the thermostat when the system is in the heating mode.  
In the event of power failure, the unit will stop. When the power is resumed,  
Power failure  
during operation  
the unit will restart automatically after three minutes.  
In heating or cooling operation. Some plastic parts may expand of shrink due to a  
sudden temperature change. In this event, a clicking sound may occur. This is normal,  
and the sound will soon disappear.  
Clicking Sound  
Clicking sound is  
heard from the air  
conditioner  
The remote control unit sends the temperature signal to the air conditioner regularly  
at three-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.

NOTE  
Care and Cleaning  
1.For safety, be sure to turn the air conditioner off and also to disconnect  
the power before cleaning.  
2.Do not pour water on the indoor unit to clean it. This will damage the  
internal components and cause an electric shock hazard.  
WARNING  
!
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  
deteraent. 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.  
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.  
CAUTION  
!

Care and Cleaning (continued)  
Anti-Mold Filter  
The anti-mode filter behind the air intake grille should be checked and cleaned  
at least once every three weeks.  
1.Grasp both ends of the air intake grille and pull it out and up.  
How to remove the  
anti-mold filter  
2.Push the anti-mold filter up slightly, and then pull it down.

Cleaning  
Use a vacuum cleaner to remove light dust. If there is sticky dust on the filter,  
wash the filter in lukewarm, soapy water, rinse it in clean water, and dry it.  
1.With the “前面”(meaning FRONT) mark facing you, slide the anti-mold
