• 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.

4P419251-1 – 2015.10

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.

BRC1E53 User reference guide 4P419251-1 – 2015.10

Items to be Strictly Observed

• 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.

CAUTION

• 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.

4P419251-1 – 2015.10

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.

BRC1E53 User reference guide 4P419251-1 – 2015.10

Basic Operation Method

• When the ON/OFF button is pressed again, the air

conditioner will stop operating and the Operation lamp will turn OFF.

Note

• When the system is stopped while in heating operation, the fan

will continue to operate for approximately 1 minute in order to eliminate the residual heat in the indoor unit.

• To prevent water leakage or system failure, do not turn OFF the

power soon after the air conditioner stops operating. Be sure to

wait at least 5 minutes so that the drain pump nishes

discharging the residual water from the indoor unit.

Characteristics of Cooling Operation

• If the cooling operation is used when the room temperature is too low, frost forms on the heat exchanger of the indoor unit which can decrease the cooling capacity. In this case, the air conditioner automatically switches to defrost operation for a while.

During defrost operation, a low airow rate or a gentle wind is used to

prevent the discharge of melt water. (The remote controller displays the fan speed that is set).

• When the outdoor air temperature is high, it takes some time until the room temperature reaches the set temperature.

Characteristics of Heating Operation

Starting operation

User reference guide BRC1E53

4P419251-1 – 2015.10

• Heating operation generally requires a longer time to attain the set

temperature compared with cooling operation. It is recommended to start operating the air conditioner in advance by using the timer.

Basic Operation Method

Perform the following operation in order to prevent the degradation of the heating capability or cold drafts. Defrost operation

Hot start (VRV only)

Outdoor temperature and heating capability

• The air conditioner will automatically go into defrost operation to

prevent frost accumulation at the outdoor unit which results in loss of the heating capacity.

• The indoor unit fan will stop, and " " (Defrost/Hot start) will be

displayed on the remote controller.

• The air conditioner will return to normal operation after approximately

6 to 8 minutes (Max 10 minutes).

• When the air conditioner goes into heating operation or defrost

operation, the indoor unit fan will stop in order to prevent a cold draft. (In that case, " " (Defrost/Hot start) will be displayed on the remote controller).

• The heating capacity of the air conditioner will drop when the outdoor

temperature decreases.

If the heating effect is insufcient, it is recommended to use another

heating appliance in combination with the air conditioner. (When a combustion appliance is used, ventilate the room regularly). Do not use the heating appliance in places where the heating

appliance is exposed to the airow of the air conditioner.

• The air conditioner is a hot air circulation type. Therefore, it takes

some time to warm up the room after the air conditioner starts operating. The indoor fan will automatically operate until the indoor temperature of the system rises to a certain level.

• If hot air stays around the ceiling and your feet feel cold, a circulator is

recommended. For details, consult your Daikin dealer.
