Safety Precautions
WARNING
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.
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.
In the case of using a load breaker provided with a fuse, make sure that ●
the capacity of the fuse is correct.
Use of an ordinary conductive wire may cause malfunctions or fi re.
Do not start or stop operating the air conditioner with the power supply ●
breaker turned ON or OFF.
Otherwise, fi re or water leakage may result.
Furthermore, the fan will rotate abruptly if power failure compensation is enabled, which
may result in injury.
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 or fi re. A high surge current from lightning or other
sources may cause damage to the air conditioner.
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.
Consult your local dealer regarding what to do in case of refrigerant ●
leakage.
When the air conditioner is to be installed in a small room, it is necessary to take proper
measures so that the amount of any leaked refrigerant does not exceed the
concentration limit in the event of a leakage.
Otherwise, this may lead to an accident due to oxygen depletion.
Be sure to install an earth leakage breaker. ●
Failure to install an earth leakage breaker may result in electric shocks or fi re.
Consult the dealer if the air conditioner submerges owing to a natural ●
disaster, such as a fl ood or typhoon.
Do not operate the air conditioner in that case, or otherwise a malfunction, electric
shock, or fi re may result.
Be sure to use a dedicated power supply for the air conditioner. ●
The use of any other power supply may cause heat generation, fi re, or product failures.
However, in the
4 English
―― Items to be Strictly Observed――
CAUTION
After prolonged use, check the unit stand and its mounts for damage. ●
If left in a damaged condition, the unit may fall and cause injury.
Do not allow a child to mount on the outdoor unit or avoid placing any ●
object on it.
Falling or tumbling may result in injury.
Do not block air inlets nor outlets. ●
Impaired air fl ow may result in insuffi cient performance or trouble.
To avoid injury, do not touch the air inlet or aluminium fi ns of the unit. ●
Do not remove the outdoor unit’s fan guard. ●
The guard protects against the unit’s high speed fan, which may cause injury.
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.
Do not place water containers (fl ower vases, etc.) on the unit, as this ●
may result in electric shocks or fi re.
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.
Do not place appliances that produce naked fl ames in places exposed to ●
the air fl ow from the unit as this may impair combustion of the burner.
Do not place heaters directly below the unit, as resulting heat can cause ●
deformation.
Be sure that children, plants or animals are not exposed directly to ●
airfl ow from the unit, as adverse effects may ensue.
Do not put fl ammable containers, such as spray cans, within 1m from the ●
blow-off mouth.
The containers may explode because the warm air output of the indoor or outdoor unit
will affect them.
Do not install the air conditioner at any place where there is a danger of ●
fl ammable gas leakage.
In the event of a gas leakage, build-up of gas near the air conditioner may result in fi re
hazards.

Safety Precautions
CAUTION
Do not sit or stand on any unstable base at the time of operating or ●
maintaining the air conditioner.
The base may topple down and injury may result.
Do not touch the motor at the time of fi lter replacement. ●
The motor in operation is at high temperatures and a burn may result.
Do not wash the air conditioner with water, as this may result in electric ●
shocks or fi re.
Perform ventilation from time to time. ●
Be careful when using the air conditioner with other heating equipment.
Insuffi cient ventilation may result in oxygen defi ciency.
Always stop the operation of the air conditioner and turn OFF the ●
breaker at the time of cleaning.
Failure to do so may result in an electric shock or injury.
Do not wash the interior of the indoor and outdoor units by yourself. ●
Always consult your Daikin dealer.
The use of an incorrect washing method or incorrect detergent may damage the resin
parts of the indoor unit or cause water leakage.
Moreover, malfunctions, smoke generation, or ignition may result if the electric parts or
motor in the indoor unit is wet with detergent.
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.
Fix the units securely. ●
If the units are not mounted securely, the units may fall or topple and injury may result.
Arrange the drain to ensure complete drainage. ●
If proper drainage from the outdoor drain pipe does not occur during air conditioner
operation, there could be a blockage due to dirt and debris build-up in the pipe.
This may result in a water leakage from the indoor unit. Under these circumstances,
stop air conditioner operation and consult your dealer for assistance.
