WARNING and CAUTION are used throughout this manual. These are very important precautions concerning safety. Be sure to observe all of them without fail.
WARNING: These are matters with possibilities leading to serious consequences such as death or serious injury due to erroneous handling.
CAUTION: These are matters with possibilities leading to injury or material damage due to erroneous handling, including probabilities leading to serious consequences in some cases.
After reading, keep this manual at a place where any user can read at any time. Furthermore, make certain that this operation manual is handed to a new user if required.
WARNING
- Avoid prolonged exposure of your body to direct streams of cold air. Your physical condition may deteriorate.
- If the air conditioner is in abnormal conditions (smell of something burning, etc.), switch the air conditioner off at the main switch, and contact the dealer where you purchased the air conditioner. Continued operation under such circumstances may result in a failure, electric shock or fire.
- Only use a qualified installer for installation of the air conditioner. Incorrect installation performed may result in a water leakage, electric shock or fire.
- Ask your dealer for improvement, repair, and maintenance. Incorrect improvement, repair, and maintenance may result in a water leakage, electric shock or fire.
- Never remove any fixed covers on the indoor or outdoor unit. Removal of the covers may expose fast moving fan blades or electrical components operating at a hazardous voltage. Contact with the blades or high voltage components may result in injury or electric shock.
- For refrigerant leakage, consult your dealer. If 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 limiting concentration. If the refrigerant leaks exceeding the level of limiting concentration, an oxygen deficiency accident may happen.
- For installation of separately sold component parts, ask a specialist only. Be sure to use separately sold component parts designated by Daikin. Incomplete installation performed by yourself may result in a water leakage, electric shock or fire.
- Ask your dealer to move and reinstall the air conditioner. Incomplete installation may result in a water leakage, electric shock or fire.
- Never insert any objects into the openings in the indoor or outdoor unit. This may damage the product or result in injury to the person inserting the object.
CAUTION
- Do not use the air conditioner for other purposes. Do not use the air conditioner for special applications such as the storage of foods, animals and plants, precision machines, and art objects. Deterioration of quality may result.
- When the air conditioner is used in combination with burners or heaters, ensure sufficient ventilation. Insufficient ventilation may result in an oxygen deficiency accident.
- Regularly check the quality of the foundation blocks. If they are left in a damaged condition, the unit may fall and result in injury.
- Do not place or use a flammable spray can near the air conditioner. Doing so may result in a fire.
- To clean the air conditioner, stop operation and switch the power off at the main switch. Otherwise, an electric shock and injury may result.
- Do not expose the indoor unit or remote controller to rain or moisture. Water or other fluids on the electrical components may result in fire or electric shock.
- Always replace any blown fuse with a fuse of the same specification. The use of the wrong type fuse may allow the electrical wiring to overheat and catch on fire. If the correct type of fuse continues to blow contact your installer or electrician.
- Do not place a burner or heater at a place directly exposed to the wind from the air conditioner. Incomplete combustion of the burner or heater may result.
- This electrical appliance is not intended for use by young children or infirm persons without supervision. Young children should be supervised to ensure that they do not play with the outdoor unit.
- Do not expose animals and plants directly to the air stream from the outdoor unit. Adverse influence to animals and plants may result.
- Do not wash the air conditioner with water. An electric shock may result.
- Do not install the air conditioner at any place where flammable gas may be present. If the gas leaks out and stays around the air conditioner, a fire may break out.
- Execute complete drain piping for perfect drainage. Incomplete piping may result in a water leakage.
- Never operate the air conditioner without the return air filter(s) in place. Operating the unit without the filter(s) will allow dust to enter the indoor unit and build up on the heat exchanger coil and fan motor. This will cause a malfunction of the unit which will not be covered by Warranty.
System Overview
WHAT TO DO BEFORE OPERATION
This operation manual is for systems with standard control. Before initiating operation, contact your Daikin dealer for the operation that corresponds to your system. If your installation has a customized control system (e.g., zone control), ask your Daikin dealer for the operation that corresponds to your system.
MAIN SWITCH
Ensure that your installer shows you the location of the main power switch of the air conditioning systems. This switch is normally located adjacent to the outdoor unit or in the fuse box / switchboard.
The main switch must be turned on at least 6 hours before the air conditioner is operated to warm up the compressor. Failure to do so may result in damage to the compressor which will not be covered by warranty.
If the air conditioner is not going to be used for an extended period of time or you are going away on holidays, the main switch should be turned off to prevent accidental operation of the air conditioner. Remember that the main switch must be turned back on at least 6 hours before operating the air conditioner.

IMPORTANT NOTES ABOUT INSTALLATION
- Ensure the outdoor unit is installed in: a. A place that can sufficiently withstand the weight of the air conditioner with less running noises and vibrations. b. A place where the hot air stream discharged from the air outlet of the outdoor unit and the running noises do not bother your neighbours.
- Ensure that there are no obstacles near the air outlet of the outdoor unit. Obstacles such as plants, boxes, fences, etc., may result in declined performance and increased running noises.
- If abnormal noises occur in use, consult your dealer.
- Ensure the drain piping from the indoor unit is free of blockage. During cooling operation, water should drip from the outlet of the indoor unit's drain piping. If there is no evidence of water from the drain outlet after several hours of cooling, it may be that the drain is blocked or the relative humidity is low. If you think the drain is blocked, stop the air conditioner and contact your installer.
- Ensure that a separate power supply circuit is provided for this air conditioner. All electrical work is to be carried out by qualified personnel according to local laws and regulations.

- To turn the air conditioner off, simply press the ON / OFF BUTTON. The OPERATION INDICATOR will turn off.
Note: On some occasions, the indoor fan will continue to run at extra low (or low) speed for approximately one minute after the unit has been switched off. This is not a malfunction; it is a function of the unit to remove excess heat from the indoor unit heat exchanger.
AUTOMATIC HEATING / COOLING CHANGEOVER (Heat Pump Models Only) (see Fig. 2)
When operated in this mode, the air conditioner will automatically switch between heating and cooling modes, depending on the room temperature and set temperature.
PMV Control (for Super Inverter Models only)
When in automatic cool/heat changeover mode, the Predicted Mean Vote (PMV) control is activated. By initially manually increasing or decreasing the set temperature (for increased comfort) over time, the PMV control "learns" and "remembers" these temperature settings as well as prevailing conditions. When similar conditions occur again, the system automatically controls temperature settings according to the learned preferences. This saves running costs (avoids over cooling/heating) and increases comfort levels.
- Press the MODE SELECTION BUTTON (if required) until the AUTO MODE INDICATOR (?) is displayed.
When AUTO MODE is selected, either the COOL or HEAT MODE INDICATOR will also be displayed along with the most recent temperature setting. The air conditioner will then measure the room temperature and select the applicable mode (heating or cooling) based on the current and desired room temperature.
PROGRAM DRY MODE (see Fig. 3)
When operated in this mode, the microprocessor prioritizes reducing humidity rather than room temperature. (Note: Some room temperature reduction may still occur depending on ambient conditions). This mode is used in very humid environments where conditions may be uncomfortable even if the room temperature is fairly low. The air conditioner will not enter dry mode if the room temperature is below 16°C.
- Press the MODE SELECTION BUTTON (if required) until the DRY MODE INDICATOR (?) is displayed.
- Press the ON / OFF BUTTON to commence operation. The OPERATION INDICATOR will illuminate.
- To turn the air conditioner off, simply press the ON / OFF BUTTON. The OPERATION INDICATOR will turn off.
Note: The SELECTED TEMPERATURE DISPLAY (8) and FAN SPEED DISPLAY (9) will not appear during PROGRAM DRY operation.
FAN MODE (see Fig. 2)
When operated in FAN MODE, only the indoor fan is energized. The outdoor unit does not operate, so heating or cooling is not provided. This mode is useful for circulating air within the building.
- Press the MODE SELECTION BUTTON (if required) until the FAN MODE INDICATOR (?) is displayed.
- Press the ON / OFF BUTTON to commence operation. The OPERATION INDICATOR will illuminate.
- Select the desired fan speed (if required) by pressing the FAN SPEED SELECTOR BUTTON.
- To turn the air conditioner off, simply press the ON / OFF BUTTON. The OPERATION INDICATOR will turn off.
Note: The SELECTED TEMPERATURE DISPLAY (8) will not appear during FAN MODE operation.
PROGRAM TIMER
The air conditioner can be programmed to automatically turn on or off in 1-hour increments up to 72 hours in advance. It may also be programmed to turn on for a determined time then off again, or vice versa, provided the last operation (switch on or off) is within 72 hours.
PROGRAMMING THE START / STOP TIME (see Fig. 4)
- Press the TIMER MODE START/STOP BUTTON once to enter program STOP mode, or twice to enter program START mode. The symbol "O" indicates STOP, and "|" indicates START. The PROGRAM START/STOP TIME INDICATOR will flash.
- Select the desired START/STOP TIME by momentarily pressing the up or down arrow PROGRAM TIME BUTTONs until the desired elapsed time is displayed. Each press increases or decreases the elapsed time by 1 hour.
- Once the desired START/STOP TIME is displayed, press the PROGRAM TIMER ON/OFF BUTTON. The PROGRAM START or STOP TIME INDICATOR will stop flashing and remain displayed.
- Operate the air conditioner in the desired mode as described above. The PROGRAM START/STOP TIME INDICATOR will count down towards zero. When zero is reached, the air conditioner will start or stop operating depending on the program set.
It is possible to set both start and stop times so that the air conditioner either starts after a predetermined time and then stops after a further predetermined time, or stops after a predetermined time and then starts again after a further predetermined time. This is achieved by setting both the on and off times as described above. For example, if you require the air conditioner to stop in 3 hours and then start up again 6 hours later, you would program a stop time of 3 hours and a start time of 9 hours (i.e., 3 + 6 hours).
CANCELLING THE START OR STOP TIME
If you change your mind and do not want the air conditioner to automatically start or stop, simply press the PROGRAM TIMER ON/OFF BUTTON, and the START or STOP TIME INDICATOR will extinguish.
15.8 Advanced Features
DEFROST FUNCTION (Heat Pump Models only)
During heating at low outside air temperatures, frost can build up on the outdoor unit heat exchanger. This build-up restricts airflow, reducing performance. The outdoor unit microprocessor monitors system performance and ambient temperature, recognizing frost build-up and activating defrost operation.
When the unit enters defrost mode, both indoor and outdoor fans stop, and the DEFROST INDICATOR (❄️) is displayed on the remote control. The unit remains in defrost mode for approximately 4 to 8 minutes (10 min. max.) while the heat exchanger warms up to defrost itself.
HOT START SYSTEM (Heat Pump Models only)
To prevent a cold draft when the air conditioner turns on in heating mode, the indoor unit has a computer-controlled hot start system. The indoor unit microprocessor monitors the indoor heat exchanger temperature and operates the indoor fan at a speed lower than normal low until the heat exchanger reaches a target temperature. The fan then switches from extra low to the set speed. (FDY90 operates at low speed).
This hot start feature is also used after defrost and during heating cycles when the compressor switches back on after the room temperature has fallen more than 1°C below the selected temperature.
AUTOMATIC RESTART AFTER POWER FAILURE
If the air conditioner is operating during a power failure, it will automatically restart in the same mode when power is restored.
DUAL REMOTE CONTROL OPERATION (Optional)
A second (optional) remote control can be added to the system for control at two different locations. This is useful in two-storey applications where one controller is upstairs and the other downstairs. When dual controls are used, the air conditioner obeys the last command entered into either controller. Both controllers display the same information.
This feature is not available if the optional set-back time clock (BRC15A61) is used.
NOTE: Program Timer setting is not possible from the second (optional) remote controller.
15.9 Optimum Operation
Observe the following precautions to ensure the system operates efficiently:
- Adjust the room temperature for a comfortable environment. Avoid excessive heating or cooling.
- Prevent direct sunlight from entering a room during cooling operation by using curtains or blinds.
- Keep doors and windows closed. If doors and windows remain open, room air will flow out, decreasing the effect of cooling and heating.
- Never place objects near the air inlet and air outlet of the unit. This may retard effectiveness or cause operation to stop.
15.10 Self Diagnosis & 15.11 Not Malfunction of the Air Conditioner
Self Diagnosis
In the unlikely event of a fault, the microprocessor will diagnose it (where possible), display a unique fault code on the remote controller, and flash the OPERATION INDICATOR on and off. If this occurs, note the fault code (e.g., A1) and contact your installer. This code will indicate the potential problem to the installer/repairer.
Not Malfunction of the Air Conditioner
The following symptoms do not indicate that the air conditioner has malfunctioned:
THE SYSTEM DOES NOT OPERATE
- The system does not restart immediately after the ON / OFF button is pressed. If the OPERATION lamp lights, the system is in its normal operating condition. It may not restart immediately because one of its safety devices has actuated to prevent the system from being overloaded. The system will turn on again automatically after the passage of three minutes.
- The system does not restart immediately when the TEMPERATURE SETTING button is returned to its former position after pushing. If the OPERATION lamp lights, the system is in its normal operating condition. It may not restart immediately because one of its safety devices has actuated to prevent the system from being overloaded. The system will turn on again automatically after the passage of three minutes.
- The system does not start when the display shows "" (UNDER CENTRALIZED CONTROL) and it flashes for a few seconds after pressing an operation button. This is because the system is under centralized control. Flashes on the display indicate that the system cannot be controlled by the remote controller.
- The system does not start immediately after the power supply is turned on. Wait one minute until the microcomputer is prepared for operation.
- The outdoor unit is stopped. This is because the room temperature has reached the set temperature. The indoor unit switches to fan operation.
WHITE MIST COMES OUT OF THE OUTDOOR UNIT
- When the system reverts to HEATING OPERATION after DEFROST OPERATION. Moisture generated by DEFROST becomes steam and is discharged.
NOISE FROM THE AIR CONDITIONER
- A ringing sound in the outdoor unit after it is started. This sound is generated by the temperature regulator working. It will quieten down after about a minute.
- A continuous low "shuh" sound is heard when the system is in COOLING or DEFROST OPERATION. This is the sound of refrigerant gas flowing through both indoor and outdoor units.
- A "shuh" sound which is heard at the start or immediately after the stop of operation or which is heard at the start or immediately after the stop of DEFROST OPERATION. This is the noise of refrigerant stopping or changing direction.
DUST FROM THE AIR CONDITIONER
- Dust may blow out from the unit after starting operation from long resting time. Dust that has settled in the unit is blown out.
THE AIR CONDITIONER GIVES OFF ODOURS
- The unit absorbs the smell of rooms, furniture, cigarettes, etc., and then emits them.
THE LIQUID CRYSTAL OF THE REMOTE CONTROLLER SHOWS "88"
- Happens immediately after the main power supply switch is turned on. Shows that the remote controller is in normal condition. Continues temporarily.
TROUBLE SHOOTING
If one of the following malfunctions occurs, take the measures shown below and contact your Daikin dealer. The system must be repaired by a qualified service person.
WARNING: When the air conditioner is in abnormal conditions (smell of something burning, etc.), switch off the main switch, and contact your dealer. Continued operation under such circumstances may result in a failure, electric shock, or fire.
- If a safety device such as a fuse, a circuit breaker, or an earth leakage circuit breaker frequently actuates, or the ON/OFF switch does not properly work. Measure: Turn off the main power switch.
- If water leaks from the unit. Measure: Stop the operation.

- Be careful with a scaffold or staging. Caution must be exercised because of work at a high place.
CLEANING THE AIR FILTER(s)
- Be sure to always clean the air filter(s) before use at the beginning of summer and winter. (Dirt and dust caught in the air filter causes a drop in airflow, which leads to a decline in performance.)
- When using the unit in a location where dirt may easily accumulate, clean the filter(s) more frequently. Once every 2 weeks is recommended.
NOTE: The air filter(s) and the suction grille(s) are supplied by your dealer. Ask your DAIKIN dealer how to clean them.
HOW TO CLEAN AIR OUTLET GRILLE
- Clean with soft cloth.
- When it is difficult to remove stains, use water or neutral detergent.
NOTE
- Do not use gasoline, benzene, thinner, polishing powder, liquid insecticide. It may cause discoloring or warping.
- Do not let the indoor unit get wet. It may cause an electric shock or a fire.
MAINTENANCE OF THE OUTDOOR UNIT
- Regularly inspect the outdoor unit to ensure the heat exchanger coil (aluminium fins) and fan outlet are not obstructed by vegetation or any other foreign objects.
- Clean the outdoor unit heat exchanger coil annually or as required by location or outdoor air quality. The coil may be cleaned by spraying the fins with low pressure water in a downwards direction (i.e., simulating heavy rain). Alternatively, have the work done by your installer.
- Regularly check the paint work of the outdoor unit for scratches or signs of corrosion. Apply touch-up or anti-corrosion paint as necessary.
START UP AFTER A LONG STOP
Confirm the following:
- Check that the air inlet and outlet are not blocked. Remove any obstacle.
- Clean the air filter(s) and outside grille. After cleaning the air filter, make sure to reattach it.
- Turn on the main power supply switch. The display on the remote controller will be shown when the power is turned on.
- To protect the unit, turn on the main power switch at least 6 hours before operation.
WHAT TO DO WHEN STOPPING THE SYSTEM FOR A LONG PERIOD
- Turn on FAN OPERATION for a half day and dry the unit. Refer to "FAN OPERATION".
- Cut off the power supply. When the main power switch is turned on, some power is being used even if the system is not operating. Turn off the main power supply switch for saving energy. The display on the remote controller will vanish when the main power switch is turned off.
