 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.
ELECTRICAL REQUIREMENTS
SAFETY INSTRUCTIONS
 Read these Operating Instructions 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 these Operating Instructions.  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.
 All wiring must conform to the local electrical codes. Consult your dealer or a qualified 
electrician for details.
 It is strongly recommended to be installed with Earth Leakage Circuit Breaker (ELCB) or 
Residual Current Device (RCD) to prevent electric shock or fire.
 Each unit must be properly grounded with a ground (or earth) wire or through the supply 
wiring.
 Wiring must be done by a qualified electrician.
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.
Pull off the power plug from a receptacle, or switch off the breaker, or switch off the power 
disconnecting mean to isolate the air conditioner from the main power supply when not in use 
for a long time.
 Confirm to authorized dealer or specialist on usage of specified refrigerant type. 
Using of refrigerant other than the specified type may cause product damage, burst 
and injury etc.
 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.
 Do not use this appliance in a potentially explosive atmosphere.
 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.
 To prevent possible hazards from insulation failure, the unit must be 
grounded.
 Do not clean inside the indoor and outdoor units by users. Engage 
authorized dealer or specialist for cleaning.
 In case of malfunction of this appliance, do not repair by yourself. Contact to the 
sales dealer or service dealer for a repair.
 Check for a leaking refrigerant! Refrigerant gas may produce a toxic gas if it comes 
in contact with fire.

SPECIAL REMARKS
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 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.

 (standby) 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
If the power supply for this unit is temporarily cut off, the unit will automatically resume operation 
(once the power is restored) using the same settings before the power was cut off.

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
(Field supplied)The air filter collects dust and other particles from the air and should be cleaned at regular 
intervals as indicated in the table below. If the filter gets blocked, the efficiency of the air 
conditioner drops greatly.
Ty p e F 2
Period (depending on filter specifications)
* Low Silhouette Ducted (F2)An air filter is not provided with this air conditioner at the time of shipment. To get clean air and 
to extend the service life of the air conditioner, an air filter must be installed in the air intake. 
For installation and cleaning the air filter, consult your dealer or service center.
The frequency with which the filter should be cleaned depends on the environment in which 
the unit is used.

TROUBLESHOOTING
If your air conditioner does not work properly, first check the following points before requesting service. If it still does not work properly, 
contact your dealer or a service center.
INDOOR UNIT
OUTDOOR UNITSymptom Cause
Noise Sound like streaming water during 
operation or after operation Sound of refrigerant liquid flowing inside unit
 Sound of drainage water through drain pipe
Cracking noise during operation or 
when operation stops.Cracking sound due to temperature changes of parts
Odor Discharged air is smelled during 
operation.Indoor odor components, cigarette odor and cosmetic odor accumurated in 
the air conditioner and its air is discharged.
Unit inside is dusty. Consult your dealer.
Dewdrop Dewdrop gets accumurated near air 
discharge during operationIndoor moisture is cooled by cool wind and accumulated by dewdrop.
Fog Fog occurs during operation in cooling 
mode.
(Places where large amounts of oil 
mist exist at restaurants.) Cleaning is necessary because unit inside (heat exchanger) is dirty. 
Consult your dealer as technical engineering is required.
 During defrost operation
Fan is rotating for a while even though operation 
stops. Fan rotating makes operation smoothly.
 Fan may sometimes rotates because of drying heat exchanger due to 
settings.
Dust Dust accumulation inside indoor unit is discharged.
At the initial high-speed operation, the fan may 
sometimes rotate faster (for 3 to 30 minutes) than 
the setting speed.This is for operation check in order to confirm whether the fan motor rotation is 
within use range.
Symptom Cause
No 
operationWhen power is turned ON instantly. Operation is not activated for the first approx. 3 minutes because compressor 
protection circuit is activated.
When operation is stopped and 
resumed immediately.
Noise Noise often occurs in heating mode. During defrost operation
Steam Steam often occurs in heating mode.
When stopped by remote controller, outdoor unit fan 
is sometimes operating for a while even though 
outdoor compressor is stopped.Fan rotating makes operation smoothly.
