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 Do not place things such as vessels containing water or anyslightly wet cloth. thing 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.
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.
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.

Remote controller holder
Attach the Titanium apatite photocatalytic air-purifying filter, deodorizing filter for streamer, and air supply filter (page 20, 23.) Turn on the power breaker
During operation (i.e. when the panel is open or being opened or closed), do not touch the panel

with your hands.

Turning on the power breaker will cause the front panel and horizontal louver to open once
and then close again. (This is a normal procedure.)

ATTENTION

Wrap the terminals with tape to insulate them before discarding batteries. Mixing with other metals or batteries may cause heat, explosion or fire.

PRECAUTION

About batteries The included batteries are provided to be used at first. Depending on when the air conditioner was manufactured, these batteries may run out in less than a year. 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. When replacing the batteries, use batteries of the same type, and replace the two old batteries together. Batteries close to their expiration dates will have to be replaced sooner. To prevent breakage or injury due to leaking or explosion, remove the batteries if the unit is not used for a long period of time. About remote controller 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. Direct sunlight on the transmitter/receiver may cause the unit to work harder.

Setting is complete.

If other messages than time appear on the display with the step 1 operation, do not operate the button for about 60 seconds. The display will return to normal. Tips for saving energy Recommended temperature setting Be careful not to cool (heat) the room too much. For cooling : 26C 28C Keeping the temperature setting at a moderate level helps save energy. For heating : 20C 22C 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. Periodically clean the filter. Please note The air conditioner consumes power even when 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. When the outdoor temperature is below 15C, turn on the breaker more than 1 hour before starting the operation. (This is to warm up the compressor.) Operating conditions Running the unit under conditions not listed below may cause the safety device to activate, stopping the unit. Also, condensation may form on the indoor unit and drip.

Repeat, aiming the remote controller at the air conditioner. During operation, the outdoor temperature may sometimes be displayed higher than it actually is in COOLING or SARARA DRYING mode or lower in HEATING mode (especially if frost has accumulated on the outdoor unit), due to the effects of the air blown from the outdoor unit or the temperature of the heat exchanger. The lowest indoor and outdoor temperature which can be displayed is -9C. This will be displayed even if the actual temperature is lower. The highest temperature is 39C. This will be displayed even if the actual temperature is higher. The indoor and outdoor temperatures and the humidity which are displayed are those near the sensors attached to the main air conditioner unit. The displayed temperature and humidity should only be taken as approximations, as they may be affected if there are objects around the sensors or due to direct sunlight, depending on where the air conditioner is installed.

If it is damaged during cleaning because it is made of paper. If it is very dirty after long use. Item Air purifying filter set Air supply filter (with frame) Part No. KAF974B42S KAF963A43
To order Titanium apatite photocatalytic air-purifying filter, deodorizing filter for streamer, air supply filter and streamer unit contact to the service shop there you bought the air conditioner. Using the dirty parts will: Prevent proper air purification. Prevent proper deodorizing. Reduce COOLING and HEATING capacity. Cause the unit to produce foul odors.
Check that the base, stand and other fittings of the outdoor unit are not decayed or corroded. Check that nothing blocks the air inlets and the outlets of the indoor unit and the outdoor unit. Check that the drain comes smoothly out of the drain hose during COOLING or DRY operation. If no drain water is seen, water may be leaking from the indoor unit. Stop operation and consult the service shop if this is the case. Is the earth wire out or disconnected in the middle? An incomplete ground wire may cause electrical shock. Contact the service shop.

Trouble Shooting

These cases are not troubles.
The following cases are not air conditioner troubles but have some reasons. You may just continue using it.
Operation does not start soon. When ON/OFF button was pressed soon after operation was stopped. When the mode was reselected. Hot air does not flow out soon after the start of heating operation.

Explanation

This is to protect the air conditioner.
You should wait for about 3 minutes.
The air conditioner is warming up.
You should wait for 1 to 4 minutes. Clicking sound can be heard either when the unit is running or stopped This is either the sound of the valves regulating the refrigerant or the electrical parts working. Sound of running water Refrigerant is flowing through the air conditioner. Blowing sound The flow of refrigerant through the air conditioner is switching. Creaking sound The air conditioner itself is expanding or shrinking due to a change in the humidity. Clopping sound Can be heard coming from inside the air conditioner when the ventilator is on and the room is shut. Open a window or turn off the ventilator. Clicking sound can be heard either when the unit is running or stopped This is the sound of the electrical parts working when the front panel opens or closes. Blowing, cracky or burning sound This is the sound of streamer discharging.

Makes a noise.

Fizzes during HUMIDIFYING or VENTILATING operation. Makes a sound during HUMIDIFYING operation. The indoor unit makes a noise even after HUMIDIFYING operation is stopped. Units stops during HEATING and the sound of running water can be heard. The outdoor unit emits water or steam.
This is the sound of humidified or ventilated air being discharged. The operation noise may change depending on the outdoor temperature and humidity.
Operation noise changes This is because the fan for humidification moves or stops.
The fan for humidification rotates for about 3 minutes after the operation stops for product protection.
The frost on the outdoor unit is being removed. You should wait for about 3 to 10 minutes.
In HEATING operation The frost on the outdoor unit melts into water or steam when the air conditioner is in defrost operation. In COOLING operation Moisture in the air condenses into water on the cool surface of outdoor unit piping and drips.
Mist comes out of the indoor unit.
