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 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 the atmosphere 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.

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 start or stop operating the air conditioner with the power supply
breaker turned ON or OFF.
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 power to the unit 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.
Safety Precautions

54PW71265-1 – 10.2011
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.
•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.
–Items to be Strictly Observed–

BRC1E52A7 Operation manual
4PW71265-1 – 10.2011 6
CAUTION
• Do not touch the motor at the time of 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 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
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 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.

6 •The Operation lamp will be turned OFF and the
system will stop operating when On/Off button is
pressed again.
* While the system is in heating operation, the
system will be in fan operation for approximately
1 minute in order to eliminate the heat in the
indoor unit after the heating operation comes to a
stop.
Note
•Do not turn power OFF soon after the system stops operating.
Be sure to wait for at least 5 minutes so that the drain
discharging device will nish discharging the residual drain.
Otherwise, water leakage or failures may result.
Characteristics of Heating Operation
Starting operation •The system in heating operation generally requires a long time to
attain the set temperature compared with the system in cooling
operation.
It is recommended to start operating the system in advance by utilizing
the timer.
Perform the following operation of the system in order to prevent the
degradation of the heating capability or cold winds from blowing out.
Defrosting
operation
•The heating capability of the system will drop if the outdoor unit frosts
up. Therefore, the system will go into defrosting operation
automatically.
•The system will stop blowing out hot air, and " " (Defrost/Hot
start) will be displayed on the remote controller.
•The system will return to normal operation with an elapse of
approximately 6 to 8 minutes (but not more than 10 minutes).
Hot start
(VRV only)
•When the system goes into heating operation, the fan will go into
breezing operation in order to prevent cold air from blowing out of the
system in defrosting operation.
(In that case, " " (Defrost/Hot start) will be displayed on the
remote controller.)

Operation manual BRC1E52A7
17 4PW71265-1 – 10.2011
Outdoor
temperature and
heating capability
•The heating capability of the system will drop with a decrease in
outdoor temperature.
If that happens, use the system along with another heating appliance.
(In the above case, be sure to ventilate the room as frequently as
possible.)
Do not use the heating appliance in places where the heating
appliance is exposed to the wind from the system.
•The system is of hot air circulation type. Therefore, it takes some time
for the room to become warm after the system starts operating.
The indoor fan will automatically go into breezing operation until the
inner temperature of the system rises to a certain level.
•If the hot air stays around the ceiling and your feet feel cold, the use of
a circulator is recommended.
For details, consult your Daikin dealer.
