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. Be sure to follow the instructions.

• 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) 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.

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

CAUTION

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.

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.
