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.  
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.  
The unit may malfunction when the receiver in the indoor unit is  
exposed to the inverter lamp light.  
Avoid:  
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.  
Power mains  
Power supply: 60 Hz, single-phase, 230/208 volts.  
ON  
To warm up the system, the power mains must be  
turned on at least five (5) hours before operation.  
Leave the power mains ON unless you will not be  
using this appliance for an extended period.  
CAUTION  
For ceiling-mounted and recessed-type indoor units, the flaps move for one  
minute when the power is supplied to the unit. This is not a malfunction.  
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 touch the unit with wet hands.  
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 extreme  
cases.  
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.

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 or spray detergent on the indoor unit to clean it.  
This will damage the internal components and may cause an  
electric shock or fire.  
Air Intake and outlet side  
(Indoor Unit)  
Clean the air intake and outlet side 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 air outlet side, be careful not to force the  
vanes out of place.  
CAUTION  
1. Never use solvents or harsh chemicals when cleaning the indoor  
unit. Do not wipe plastic parts 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.  
Air filter  
The air filter collects dust and other particles from the air and should be  
cleaned about once every six months (Recessed type) or two weeks  
(ceiling-mounted type and wall-mounted type). If the filter gets blocked, the  
efficiency of the air conditioner drops greatly.  
The frequency with which the filter should be cleaned depends on the  
environment in which the unit is used.  
NOTE  
How to remove the filter  
Recessed type:  
1. Remove the bolt screw on each side out of the latch using a  
screwdriver. (After cleaning, be sure to reattach the two bolt screws.)  
2. Press on the two latches of the air intake grille with your thumbs in the  
direction of the arrow to open the grille.  
3. Open the air intake grille downward.  
CAUTION  
When cleaning the air filter, never remove the safety string. If it is  
necessary to remove it for servicing and maintenance inside, be sure  
to reinstall the safety string securely (hook on the grille side) after the  
work.  
4. Remove the air filter attached to the air intake grille.

Tips for Energy Saving  
Do not  
Block the air intake and outlet of the unit. If either is 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.  
Should the power fail while the unit is running  
NOTE  
If the power supply for this unit is temporarily interrupted the unit will  
automatically resume operation (once the power is restored) with the same  
settings that were in effect before the power was interrupted.
