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

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.

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.
1
•
•
The
indicator remains displayed 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) 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.
Air filter
The air filter collects dust and other particles from the air and should be
cleaned at regular intervals as indicated in the table below or when the
filter indication ( ) on the display of the remote control unit (wired
type) shows that the filter needs cleaning. If the filter gets blocked, the
efficiency of the air conditioner drops greatly.

•
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

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
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.
