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.  
Power mains  
To warm up the system, the power mains  
must be turned on at least five (5) hours  
before operation. Leave the power mains  
ON  
ON unless you will not be using this  
appliance for an extended period.

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.  
•
The 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  
an extreme case.  
• 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 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  
repeats the cycle of turning on and off automatically.  
In order to prevent the humidity in the room from rising again, the indoor  
fan also turns off when the unit stops operating.  
•
•
•
The fan speed is set to “LO.” automatically, and cannot be adjusted.  
“DRY” operation is not possible if the outdoor temperature is 59 °F or  
less.  
Heating Operation  
Heating performance  
•
•
Because this appliance heats a room by utilizing 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 heat pump, use another heating appliance in conjunction with this  
unit.  
Defrosting  
When the outdoor temperature is low, frost or ice may form on the  
outdoor heat exchanger coil, reducing the heating performance.  
When this happens, a microcomputer-controlled defrosting system  
operates. At the same time, the fan on the indoor unit stops (or runs at  
very low speed in some cases) and the  
(STANDBY) indicator appears  
on the display until defrosting is completed. Heating operation then  
restarts after several minutes. (This interval will vary slightly depending  
upon the outdoor temperature and the way in which frost forms.)  
(STANDBY) on  
the display  
•
For several minutes after the start of heating operation, the indoor fan will  
not start running (or it will run at very low speed in some cases) until the  
indoor heat exchanger coil has warmed up sufficiently. This is because a  
cold draft prevention system is operating. During this period, the  
(STANDBY) indicator remains displayed.  
•
•
The  
indicator remains displayed during defrosting or when the  
1
compressor has been turned off (or when the unit is running at very low  
speed) by the thermostat when the system is in the heating mode.  
Upon completion of defrosting and when the compressor is turned on  
again,  
(STANDBY) will turn off automatically as heating operation  
resumes.  
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.

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.  
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.  
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.

•
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.  
Do not 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.

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.  
Power mains  
To warm up the system, the power mains  
must be turned on at least five (5) hours  
before operation. Leave the power mains  
ON  
ON unless you will not be using this  
appliance for an extended period.  
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.  
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.  
• 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  
an extreme case.  
• 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 or heat the room too much if babies or invalids are  
present.

Special Remarks  
Heating Operation  
Heating performance  
•
Because this appliance heats a room by utilizing 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 heat pump, use another heating appliance in conjunction with this  
unit.  
Defrosting  
•
When the outdoor temperature is low, frost or ice may form on the  
outdoor heat exchanger coil, reducing the heating performance.  
When this happens, a microcomputer-controlled defrosting system  
operates. At the same time, the fan on the indoor unit stops (or runs at  
very low speed in some cases) and the  
(STANDBY) lamp lights on the  
indoor unit until defrosting is completed. Heating operation then restarts  
after several minutes. (This interval will vary slightly depending upon the  
outdoor temperature and the way in which frost forms.)  
(STANDBY) lamp  
on the indoor unit  
•
For several minutes after the start of heating operation, the indoor fan will  
not start running (or it will run at very low speed in some cases) until the  
indoor heat exchanger coil has warmed up sufficiently. This is because a  
cold draft prevention system is operating. During this period, the  
(STANDBY) lamp remains lit.  
•
•
(STANDBY) lamp remains lit during defrosting or when the  
compressor has been turned off (or when the unit is running at very low  
speed) by the thermostat when the system is in the heating mode.  
Upon completion of defrosting and when the compressor is turned on  
again,  
(STANDBY) lamp will light off automatically as the heating  
operation resumes.  
ADDRESS switch setting  
When setting up two or three air conditioners in one room, you can control the  
air conditioners correctly by setting the ADDRESS switches of the Operation  
Controllers and the Wireless Remote Controllers.  
You can control the air conditioners:  
1) with one wireless remote controller changing the ADDRESS switch setting  
of the wireless remote controller.  
2) with each wireless remote controller having the ADDRESS switch set  
differently.

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.  
Be sure to place the wireless remote controller where it can operate the  
air conditioner correctly.

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.  
Do not 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.  
2
•
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.
