READ BEFORE OPERATION

Safety precautions

• Keep this manual where the operator can easily find them.

• Read this manual attentively before starting up the unit.

• For safety reason the operator must read the following cautions carefully.

• This manual classifies precautions into WARNINGS and CAUTIONS. Be sure to follow all precau­tions below: they are all important for ensuring safety.

WARNING

If you do not follow these instructions exactly, the unit may
cause property damage, personal injury or loss of life.

Never do. Be sure to follow the instructions.

Be sure to earth the air conditioner.

Never touch the air conditioner (including the
remote controller) with a wet hand.

If you do not follow these instructions exactly, the unit may
cause minor or moderate property damage or personal injury.

Never cause the air conditioner (including the
remote controller) to get wet.

CAUTION

WARNING

• In order to avoid fire, explosion or injury, do not operate the unit when harmful, among
which flammable or corrosive gases, are detected near the unit.

• It is not good for health to expose your body to the air flow for a long time.

• Do not put a finger, a rod or other objects into the air outlet or inlet. As the fan is rotating at
a high speed, it will cause injury.

• Do not attempt to repair, relocate, modify or reinstall the air conditioner by yourself. Incorrect work
will cause electric shocks, fire etc.
For repairs and reinstallation, consult your Daikin dealer for advice and information.

• The refrigerant used in the air conditioner is safe. Although leaks should not occur, if for
some reason any refrigerant happens to leak into the room, make sure it does not come in
contact with any flame as of gas heaters, kerosene heaters or gas range.

• If the air conditioner is not cooling (heating) properly, the refrigerant may be leaking, so call your dealer.
When carrying out repairs accompanying adding refrigerant, check the content of the repairs with our service staff.

• Do not attempt to install the air conditioner by your self. Incorrect work will result in water leakage,
electric shocks or fire. For installation, consult the dealer or a qualified technician.

• In order to avoid electric shock, fire or injury, if you detect any abnormally such as smell of fire, stop
the operation and turn off the breaker. And call your dealer for instructions.

• Depending on the environment, an earth leakage breaker must be installed. Lack of an earth
leakage breaker may result in electric shocks or fire.

• The air conditioner must be earthed. Incomplete earthing may result in electric shocks. Do
not connect the earth line to a gas pipe, water pipe, lightning rod, or a telephone earth line.

CAUTION

In order to avoid any quality deterioration, do not use the unit for cooling precision instru-

•
ments, food, plants, animals or works of art.

• Never expose little children, plants or animals directly to the air flow.

•

Do not place appliances which produce open fire in places exposed to the air flow from the unit or
under the indoor unit. It may cause incomplete combustion or deformation of the unit due to the heat.

2

• Do not block air inlets nor outlets. Impaired air flow may result in insufficient performance or trouble.

• Do not stand or sit on the outdoor unit. Do not place any object on the unit to avoid injury, do not
remove the fan guard.

• Do not place anything under the indoor or outdoor unit that must be kept away from moisture. In
certain conditions, moisture in the air may condense and drip.

• After a long use, check the unit stand and fittings for damage.

• Do not touch the air inlet and alminum fins of outdoor unit. It may cause injury.

• The appliance is not intended for use by young children or infirm persons without supervision.

• Young children should be supervised to ensure that they do not play with the appliance.

• To avoid oxygen deficiency, ventilate the room sufficiently if equipment with burner is used
together with the air conditioner.

•

Before cleaning, be sure to stop the operation, turn the breaker off or pull out the supply cord.

• Do not connect the air conditioner to a power supply different from the one as specified. It
may cause trouble or fire.

• Arrange the drain hose to ensure smooth drainage. Incomplete draining may cause wetting of the
building, furniture etc.

• Do not place objects in direct proximity of the outdoor unit and do not let leaves and other debris
accumulate around the unit.
Leaves are a hotbed for small animals which can enter the unit. Once in the unit, such animals can
cause malfunctions, smoke or fire when making contact with electrical parts.

• Do not operate the air conditioner with wet hands.

• Do not wash the indoor unit with excessive water, only use a slightly wet cloth.

•

Do not place things such as vessels containing water or anything else on top of the unit. Water
may penetrate into the unit and degrade electrical insulations, resulting in an electric shock.

Installation site.

■ To install the air conditioner in the following types of environments, consult the dealer.

• Places with an oily ambient or where steam or soot occurs.

• Salty environment such as coastal areas.

• Places where sulfide gas occurs such as hot springs.

• Places where snow may block the outdoor unit.

The drain from the outdoor unit must be discharged to a place of good drainage.

Consider nuisance to your neighbours from noises.

■ For installation, choose a place as described below.

•

A place solid enough to bear the weight of the unit which does not amplify the operation noise or vibration.

• A place from where the air discharged from the outdoor unit or the operation noise will not annoy
your neighbours.

Electrical work.

• For power supply, be sure to use a separate power circuit dedicated to the air conditioner.

System relocation.

• Relocating the air conditioner requires specialized knowledge and skills. Please consult the
dealer if relocation is necessary for moving or remodeling.

Preparation Before Operation

■ To set the batteries

1. Slide the front cover to take it off.

2. Set two dry batteries (LR03·AAA).

3. Set the front cover as before.

■ To operate the remote controller

• To use the remote controller, aim the transmitter at the indoor
unit. If there is anything to block signals between the unit and
the remote controller, such as a curtain, the unit will not
operate.

• Do not drop the remote controller. Do not get it wet.

• The maximum distance for communication is about 7m.

■ To fix the remote controller holder
on the wall

1. Choose a place from where the signals

reach the unit.

2. Fix the holder to a wall, a pillar, or similar

location with the screws procured locally.

ATTENTION

■

About batteries

• When replacing the batteries, use batteries of the same type, and replace the two old batteries together.

• When the system is not used for a long time, take the batteries out.

• We recommend replacing once a year, although if the remote controller display begins to fade or if reception
deteriorates, please replace with new alkaline batteries. Using manganese batteries reduces the lifespan.

• The attached batteries are provided for the initial use of the system.
The usable period of the batteries may be short depending on the manufactured date of the air conditioner.

■

About remote controller

• Never expose the remote controller to direct sunlight.

• Dust on the signal transmitter or receiver will reduce the sensitivity. Wipe off dust with soft cloth.

• Signal communication may be disabled if an electronic-starter-type fluorescent lamp (such
as inverter-type lamps) is in the room. Consult the shop if that is the case.

• If the remote controller signals happen to operate another appliance, move that appliance
to somewhere else, or consult the shop.

NOTE

• If the indoor unit’s internal clock is not set to the correct time, the WEEKLY TIMER will not
operate punctually.

■ Turn the breaker ON

• Turning ON the breaker closes the flap. (This is a normal procedure.)

NOTE

■

Tips for saving energy

• Be careful not to cool (heat) the room too much.
Keeping the temperature setting at a moderate level helps save energy.

• Cover windows with a blind or a curtain.
Blocking sunlight and air from outdoors increases the cooling (heating) effect.

• Clogged air filters cause inefficient operation and waste energy.
Clean them once in about every two weeks.

■

Please note

• The air conditioner always consumes 15-35 watts of electricity even while it is not operating.
If you are not going to use the air conditioner for a long period, for example in spring or autumn, turn the breaker OFF.

•

• Use the air conditioner in the following conditions.
