CAUTION
• Do not play with the unit or its remote controller.
Accidental operation by a child may result in impairment of bodily functions and harm
health.
• Never disassemble the remote controller.
Touching the interior parts may result in electric shocks or re.
Consult your Daikin dealer or authorized contractor for internal inspections and
adjustments.
• To avoid electric shocks, do not operate with wet hands.
• Do not wash the remote controller.
Doing so may cause electric leakage and result in electric shocks or re.
• Do not leave the remote controller wherever there is a risk of wetting.
If water gets into the remote controller there is a risk of electrical leakage and damage to
electronic components.
Indoor Unit and Outdoor Unit
WARNING
• Be aware that prolonged, direct exposure to cool or warm air from the air
conditioner or to air that is too cold or too warm can be harmful to your
physical condition and health.
• Do not place objects, including rods, your ngers, etc. in the air inlet or
outlet.
Injury may result due to contact with the air conditioner's highspeed fan blades.
• Contact professional personnel about attachment of accessories and be
sure to use only accessories specied by the manufacturer.
If a defect results from your own workmanship, it may result in water leaks, electric
shock or re.
• Do not use the product in atmospheres contaminated with oil vapor,
such as cooking oil or machine oil vapor.
Oil vapor may cause crack damage, electric shocks or re.
• Do not use the product in places with excessive oily smoke, such as
cooking rooms or in places with ammable gas, corrosive gas or metal
dust.
Using the product in such places may cause re or product failures.
• Beware of 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 qualied service
person conrms that the leakage has been repaired.
Items to be Strictly Observed

BRC2E52C7 / BRC3E52C7 Operation manual
4P368042-1 - 2014.02 4
Items to be Strictly Observed
WARNING
• 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 re.
• Do not use the power supply breaker to start or stop the air conditioner.
Otherwise, 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 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 the power and contact your local dealer.
Continued operation under such circumstances may result in a failure, electric shocks or
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 re.
• Consult the dealer if the air conditioner submerges owing to a natural
disaster such as a ood or typhoon.
Do not operate the air conditioner in that case or otherwise a malfunction, electric shock
or 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, re or product failures.

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ow may result in insufcient performance or trouble.
• To avoid injury, do not touch the air inlet or aluminium 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 lter dirt
or drain blockage may cause dripping, resulting in fouling or failure of the object
concerned.
• Do not place water containers (ower vases, etc). on the unit, as this
may result in electric shocks or 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 ames in places exposed to
the air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
airow from the unit as adverse effects may ensue.
• Do not put 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
ammable gas leakage.
In the event of a gas leakage, build-up of gas near the air conditioner may result in re
hazards.

Items to be Strictly Observed
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 occur.
• Do not touch the motor when replacing the lter.
The motor can be very hot which may result in burns.
• Do not wash the air conditioner with water as this may result in electric
shocks or re.
• Perform ventilation from time to time.
Be careful when using the air conditioner with other heating equipment.
Insufcient ventilation may result in oxygen deciency.
• Always stop the operation of the air conditioner and turn OFF the power
supply breaker when 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
the motor in the indoor unit come in contact with a detergent or water.
• 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 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 result in personal
injury.
• 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 water leakage from the indoor unit. Under these circumstances, stop
the air conditioner operation and consult your dealer for assistance.
