SPECIAL REMARKS

‘‘DRY’’ Operation • 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 • Since this air conditioner utilizes outside air for heating, its heating performance

deteriorates as outside temperature decreases. (Due to heat pump system)

• It will take some time until the room becomes warmer after heating operation started. (Due

to hot air circulation system in order to heat a whole room)

Defrosting • This appliance may start defrosting operation to melt frost form in the outdoor unit during

long hour heating operation mode.

The indoor unit fan will stop for about 5 to 10 minutes at this time.

Heating Standby The remote controller shows “ ” (Heating standby) on the display in the following mode and

the indoor unit fan may be controlled.

• When operation started (Indoor unit fan stops for maximum 6 minutes.)

• When Thermostat activated

• When defrosting (Indoor unit fan stops.)

Remote Control Sensor The temperature sensor in the indoor unit normally senses the room temperature and can also

sense the ambient temperature of the remote controller.

For the details, consult the shop you purchased.

Should the power failure

occurs while the

unit is running

When the unit automatically resumes operation after temporary power failure, it uses the same

settings before the power was cut off.

F569999_EN.fm Page 7 Tuesday, June 23, 2015 9:24 AM

CARE AND CLEANING

Do not attempt to clean inside the unit by yourself.

Refer to the section “Care and Cleaning” in the Installation Instructions.

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 when the filter indication ( ) on the display of the remote controller (wired type)

shows that the filter needs cleaning. 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

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

Symptom 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 operation

Indoor 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 rotate because of drying heat exchanger due to

settings.

Wind-direction changes while operating.

Wind-direction setting cannot be made.

Wind-direction cannot be changed.

• When air discharge temperature is low or during defrost operation,

horizontal wind flow is made automatically.

• Flap position is occasionally set up individually.

When wind-direction is changed, flap operates

several times and stops at designated position.

When wind-direction is changed, flap operates after searching for standard

position.

Dust Dust accumulation inside indoor unit is discharged.

Poor cooling or heating performance The indoor unit is initially designed to control the indoor temperature detected

by the built-in room sensor inside the indoor unit.

Due to indoor unit installation position, however, the built-in sensor may

occasionally sense temperature improperly; for example, temperature

difference between the ceiling and floor, lighting apparatus, electric fan,

windows or waist-high partition walls, etc.

In this case, the unit does not operate properly at the desired temperature.

You may change the use of the temperature sensor inside the indoor unit to

that of the remote controller.

Then the desired room temperature can be controlled properly.

For details, consult your dealer.

F569999_EN.fm Page 9 Tuesday, June 23, 2015 9:24 AM

CHECK BEFORE REQUIRING SERVICES

If your air conditioner still does not work properly although you checked the points as described above, first stop the operation and

turn off the power switch. Then contact your dealer and report the serial number and symptom. Never repair your air conditioner by

yourself since it is very dangerous for you to do so. You also report if the inspection mark and the letters E, F, H, L, P in

combination with the numbers appear on the LCD of the remote controller.

TIPS FOR ENERGY SAVING

Avoid

• 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.

• 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

If the power supply for this unit is temporarily cut off, the unit will automatically resume operation once power is restored using the

same settings before the power was interrupted.

Symptom Cause Remedy

Air conditioner does not run at

all although power is turned

on.

Power failure or after power failure Press ON/OFF operation button on remote controller

again.

Operation button is turned off. • Switch on power if breaker is turned off.

• If breaker has been tripped, consult your dealer

without turning it on.

Fuse blow out. If blown out, consult your dealer.

Poor cooling or heating

performance
