Safety Precautions

Read the precautions in this manual carefully before operating the unit.

• Keep this manual where the operator can easily ﬁ nd it.

• Read the precautions in this manual carefully before operating the unit.

• This appliance is intended to be used by expert or trained users in shops, in light industry and on farms, or for commercial and household use by lay persons.

• Sound pressure level is less than 70 dB (A).

• The precautions described herein are classiﬁ ed as WARNING and CAUTION. They both contain important information regarding safety. Be sure to observe all precautions without fail.

WARNING

Failure to follow these instructions properly may result in personal injury or loss of life.

Never attempt.

• After reading, keep this manual in a convenient place so that you can refer to it whenever necessary. If the equipment is transferred to a new user, be sure also to hand over the manual.

WARNING

• The appliance must be stored in a room without continuously operating ignition sources (for example: open ﬂ ames, an operating gas appliance or an operating electric heater).

• In order to avoid ﬁ re, explosion or injury, do not operate the unit when harmful gases (e.g. ﬂ ammable or corrosive) are detected near the unit.

• Be aware that prolonged, direct exposure to cool or warm air from the air conditioner, or to air that is too cool or too warm can be harmful to your physical condition and health.

• Do not place objects, including rods, your ﬁ ngers, etc., in the air inlet or outlet. Product damage or personal injury may result due to contact with the air conditioner’s high-speed fan blades.

• Do not attempt to repair, dismantle, reinstall or modify the air conditioner yourself as this may result in water leakage, electric shocks or ﬁ re hazards.

• Do not use ﬂ ammable spray near the air conditioner, or otherwise ﬁ re may result.

• Do not use refrigerant other than the one indicated on the outdoor unit (R410A/R32) when installing, moving or repairing. Using other refrigerants may cause trouble or damage to the unit, and personal injury.

• To avoid electric shocks, do not operate with wet hands.

• Do not wash the air conditioner with water, as this may result in electric shocks or ﬁ re.

• Do not place water containers (vases etc.) above the unit, as this may result in electric shocks or ﬁ re hazards.

• Beware of ﬁ re in case of refrigerant leakage. If the air conditioner is not operating correctly, i.e. not generating cool or warm air, refrigerant leakage could be the cause. Consult your dealer for assistance. The refrigerant within the air conditioner is safe and normally does not leak. However, in the event of a leakage, contact with a naked burner, heater or cooker may result in generation of noxious gas. Do not longer use the air conditioner until a qualiﬁ ed service person conﬁ rms that the leakage has been repaired.

• Do not attempt to install or repair the air conditioner yourself. Improper workmanship may result in water leakage, electric shocks or ﬁ re hazards. Please contact your local dealer or qualiﬁ ed personnel for installation and maintenance work.

• When the air conditioner is malfunctioning (giving off a burning odour, etc.) turn off power to the unit and contact your local dealer. Continued operation under such circumstances may result in a failure, electric shocks or ﬁ re hazards.

•

Be sure to install an earth leakage breaker. Failure to install the earth leakage breaker may result in electric shocks or ﬁ re.

• Be sure to earth the unit. Do not earth the unit to a utility pipe, lightning conductor or telephone earth lead. Imperfect earthing may result in electric shocks.

Be sure to follow the instructions.

FTXP models are filled with R32 refrigerant.

CAUTION

Failure to observe these instructions properly may result in property damage or personal injury, which may be serious depending on the circumstances.

Be sure to establish an earth connection.

CAUTION

• Do not use the air conditioner for purposes other than those for which it is intended. Do not use the air conditioner for cooling precision instruments, food, plants, animals or works of art as this may adversely affect the performance, quality and/or longevity of the object concerned.

Read Before Operation

Safety Precautions

• Do not expose plants or animals directly to airﬂ ow from the unit as this may cause adverse effects.

• Do not place appliances that produce naked ﬂ ames in places exposed to the airﬂ ow from the unit as this may impair

combustion of the burner.

• Do not block air inlets nor outlets. Impaired airﬂ ow may result in insufﬁ cient performance or trouble.

• Do not sit on the outdoor unit, put things on the unit, or pull the unit. Doing so may cause accidents, such as falling or

toppling down, thus resulting in injury, product malfunctioning, or product damage.

• Do not place objects that are susceptible to moisture directly beneath the indoor or outdoor units. Under certain

conditions, condensation on the main unit or refrigerant pipes, air ﬁ lter dirt or drain blockage may cause dripping, resulting in fouling or failure of the object concerned.

• After prolonged use, check the unit stand and its mounts for damage. If they are left in a damaged condition, the unit

may fall and cause injury.

• To avoid injury, do not touch the air inlet or aluminium ﬁ ns of the indoor or outdoor units.

• The appliance is not intended for use by unattended young children or inﬁ rm persons. Impairment of bodily functions

and harm to health may result.

• This appliance can be used by children aged from 8 years and above and persons with reduced physical, sensory or

mental capabilities or lack of experience and knowledge if they have been given supervision or instruction concerning use of the appliance in a safe way and understand the hazards involved.

• Children shall not play with the appliance.

• Cleaning and user maintenance shall not be made by children without supervision.

• Avoid impacts to the indoor and outdoor units, or otherwise product damage may result.

• Do not place ﬂ ammable items, such as spray cans, within 1m of the air outlet.

The spray cans may explode as a result of hot air from the indoor or outdoor units.

•

Be careful not to let pets urinate on the air conditioner. Urination on the air conditioner may result in electric shocks or ﬁ re.

• Do not wash the air conditioner with water, as this may result in electric shocks or ﬁ re.

• Do not place water containers (vases etc.) above the unit, as this may result in electric shocks or ﬁ re hazards.

• To avoid oxygen depletion, ensure that the room is adequately ventilated if equipment such as a burner is used

together with the air conditioner.

• Before cleaning, be sure to stop unit operation, turn off the circuit breaker or remove the power cord. Otherwise, an

electric shock and injury may result.

• Only connect the air conditioner to the speciﬁ ed power supply circuit. Power supplies other than the one speciﬁ ed

may result in electric shocks, overheating and ﬁ res. Arrange the drain hose to ensure smooth drainage. Imperfect drainage 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 ﬁ re when making contact with electrical parts.

• Do not place objects around the indoor unit.

Doing so may have an adverse inﬂ uence on the performance, product quality, and life of the air conditioner.

• Keep out of children’s reach to ensure that they do not play with the appliance.

Installation site.

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

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

• Salty environment such as coastal areas.

• Places where sulﬁ de gas occurs such as hot springs.

• Places where snow may block the outdoor unit.

 Be sure to follow the instructions below.

• The indoor unit is at least 1m away from any television or radio set (unit may cause interference with the picture or sound).

• 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.

Outdoor unit

Note for Multi System

Multi system has one outdoor unit connected to multiple indoor units.

 Selecting the operation mode

With the priority room setting present but inactive or not present.

When more than one indoor unit is operating, priority is given to the ﬁ rst unit that was turned on. In this case, set the units that are turned on later to the same operation mode as the ﬁ rst unit. Otherwise, they will enter the standby state, and the OPERATION lamp will ﬂ ash: this does not indicate malfunction.

NOTE

 Notes on operation mode for multi system

• COOL, DRY and FAN operation may be used at the same time.

• AUTO operation automatically selects COOL operation or HEAT operation based on the room temperature. Therefore, AUTO operation is available when selecting the same operation mode as that of the room with the ﬁ rst unit to be turned on.

CAUTION

• Normally, the operation mode in the room where the unit is ﬁ rst run is given priority, but the following situations are exceptions, so please keep this in mind. If the operation mode of the ﬁ rst room is FAN operation, then using HEAT operation in any room after this will give priority to HEAT operation. In this situation, the air conditioner running in FAN operation will go on standby, and the OPERATION lamp will ﬂ ash.

English

With the priority room setting active.

Refer to priority room setting on the next page.

 NIGHT QUIET mode (Available only for COOL operation)

NIGHT QUIET mode requires initial programming during installation. Please consult your retailer or dealer for assistance. NIGHT QUIET mode reduces the operation noise of the outdoor unit during the nighttime hours to prevent annoyance to neighbors.

• The NIGHT QUIET mode is activated when the temperature drops 5°C or more below the highest temperature recorded that day. Therefore, when the temperature difference is less than 5°C, this function will not be activated.

• NIGHT QUIET mode reduces slightly the cooling efﬁ ciency of the unit.

Note for Multi System

 COOL/HEAT mode lock

The COOL/HEAT mode lock requires initial programming during installation. Please consult your authorized dealer for assistance. The COOL/HEAT mode lock sets the unit forcibly to either COOL or HEAT operation. This function is convenient when you wish to set all indoor units connected to the multi system to the same operation mode.

NOTE

• The COOL/HEAT mode lock cannot be activated together with the priority room setting.

 Priority room setting

The priority room setting requires initial programming during installation. Please consult your authorized dealer for assistance. The room designated as the priority room takes priority in the following situations.

Operation mode priority

• As the operation mode of the priority room takes precedence, the user can select a different operation mode from other rooms.

[Example]

• Room A is the priority room in the examples. When COOL operation is selected in room A while operating the following modes in room B, C and D :

FAQ

Indoor unit

The air conditioner stops generating airﬂ ow during operation.

• Once the set temperature is reached, the airﬂ ow rate is reduced and operation stopped in order to avoid generating cool airﬂ ow (during heating) or in order to keep the humidity from rising (during cooling). Operation will resume automatically when the indoor temperature rises or falls.

HEAT operation stops suddenly and a

ﬂ owing sound is heard.

• The outdoor unit is defrosting. HEAT operation starts after the frost on the outdoor unit has been removed. This can take about 4 to 12 minutes.

Operation does not start soon.

 When or any direct operation button

was pressed soon after operation was stopped.

 When the mode was reselected.

• This is to protect the air conditioner. You should wait for about 3 minutes.

Different sounds are heard.

 A sound like ﬂ owing water

• This sound is generated because the refrigerant in the air conditioner is ﬂ owing.

•

This is a pumping sound of the water in the air conditioner and can be heard when the water is pumped out from the air conditioner during COOL or DRY operation.

 Blowing sound

• This sound is generated when the ﬂ ow of the refrigerant in the air conditioner is switched over.

 Ticking sound

• This sound is generated when the cabinet and frame of the air conditioner slightly expand or shrink as a result of temperature changes.

 Whistling sound

• This sound is generated when refrigerant ﬂ ows during defrosting operation.

 Clicking sound during operation or idle time

• This sound is generated when the refrigerant control valves or the electrical parts operate.

 Clopping sound

• This sound is heard from the inside of the air conditioner when the exhaust fan is activated while the room doors are closed. Open the window or turn off the exhaust fan.

Outdoor unit

The outdoor unit emits water or steam.

 In HEAT operation

• The frost on the outdoor unit melts into water or steam when the air conditioner is in defrosting operation.

 In COOL or DRY operation

• Moisture in the air condenses into water on the cool surface of the outdoor unit piping and drips.
