air conditioner comes under the term “appliances not accessible to
the general public”.
The precautions described below are WARNING and CAUTION. These are very important precautions
concerning safety. Be sure to observe all of them without fail.
WARNING ...... These are the matters with possibilities leading to serious consequences such as death or serious injury due
to erroneous handling.
CAUTION ....... These are the 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 componenets 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.

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.
Reguarly 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.

WHAT TO DO BEFORE OPERATION
This operation manual is for the following 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 (eg 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.

!
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.
FUNCTIONS OF THE REMOTE CONTROLLER

AUTOMATIC HEATING / COOLING CHANGEOVER
(Heat Pump Models Only) (see Fig. 2)
PMV Control (for Super Inverter Models only)
1
TEST
During the heating mode you may notice the indoor fan changing
speed. This is due to the fan switching from the selected fan
speed to extra low (or low) when the desired room temperature
is reached and the compressor cycles off.
This is to avoid cold draughts.
When the air conditioner is operated in this mode, it will
automatically switch between the heating and cooling
modes, depending on the room temperature and set
temperature.
2
hr
Notes:
As the air conditioner incorporates a hot start system, the indoor
fan will run at an extra low (or low) speed irrespective of the
selected fan speed for a few minutes when the unit is first turned
on. This is to avoid cold draughts.
When in the automatic cool / heat changeover
mode, the Predicted Mean Vote (PMV) control is
activated. By initially manually increasing or
decreasing the set temperature in this mode (for
increased comfort) over a period of time, the PMV
control “learns” and “remembers” these
temperature settings as well as prevailing
conditions - both inside and outside.
When similar conditions occur again, the system
automatically controls the temperature settings
according to the learnt preferences. This not only
can save in running costs (as it avoids over cooling
and over heating) but can also increase comfort
levels.
1. Press the MODE SELECTION BUTTON (20) (if
required) until the AUTO MODE INDICATOR (
is displayed.
)
When the AUTO MODE is selected either the COOL
or HEAT MODE INDICATOR will also be displayed
along with the most recent temperature setting.
(ie. if the last adjustment you made was to set the
cooling mode temperature to 23° then when you
select the AUTO MODE it will display AUTO
COOLING at a temperature of 23°). The air
conditioner will then measure the room
temperature and select the applicable mode
(ie. heating or cooling) based on the current and
desired room temperature.
2. Adjust the desired room temperature (if required)
by momentarily pressing on the up or down arrow
TEMPERATURE SET BUTTON's (17) until the
desired temperature is displayed. Each press of
the button will increase or decrease the desired
temperature by 1 degree. The desired temperature
may be set in the range of 16 - 32 degrees.

It is possible to set both the start and stop time 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 time as
described above. For example if you require the air
conditioner to stop in 3 hours time and then start up
again 6 hours later you would program a stop time of
3 hours and a start time of 9 hours (ie. 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 (14) and the
START or STOP TIME INDICATOR will extinguish.

Advanced Features
DEFROST FUNCTION (Heat Pump Models only)
During heating at low outside air temperatures it is
possible for frost to build up on the outdoor unit heat
exchanger. This build up of frost will restrict the airflow
through the heat exchanger and therefore the
performance of the air conditioner will gradually be
reduced. As the outdoor unit microprocessor is
constantly monitoring system performance and
ambient temperature it will recognise that frost is
building up on the heat exchanger and activate defrost
operation.
When the unit enters the defrost mode both the indoor
and outdoor fans will stop and the DEFROST
INDICATOR (
) will be displayed on the
remote control. The unit will remain in the defrost
mode for around 4 to 8 minutes (10 min. max.) during
which time the heat exchanger will warm up to defrost
itself.than 1°C below the selected temperature.
8
The indoor unit microprocessor monitors the
temperature of the indoor heat exchanger and
operates the indoor fan at a speed lower than the
normal low until the heat exchanger temperature
reaches a target temperature. When this target is
reached the fan switches from extra low to set speed.
(FDY90 operates at low speed)
This hot start feature is also utilised after defrost and
during the heating cycle 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 the
power is restored.
DUAL REMOTE CONTROL OPERATION (Optional)
A second (optional) remote control may be added to
the system to allow setting and control of the unit at
two different locations. This is particularly useful in
two storey applications where one controller can be
installed upstairs and the other controller downstairs.
When dual controls are used the air conditioner will
obey the last command entered into either controller.
Both controllers will display the same information so if
the temperature on the downstairs controller is
increased from 21 to 23 degrees, the upstairs
controller will also indicate 23 degrees. 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 the doors and
windows remain open, room air will flow out and
decrease the effect of cooling and heating.
! Never place objects near the air inlet and the air
outlet of the unit. It may retard effectiveness or
cause operation to stop.
!
Turn off the main power supply switch when not
using for long periods of time. Electricity is
consumed as long as the switch is on. Turn off the
main power supply switch in order to save energy.
Turn on the main power supply switch 6 hours
before restarting operation in order to ensure
smooth operation. (Refer to MAINTENANCE)
! Ventilate the room regularly.
Using the unit for long periods of time requires
regular ventilation of the room.
! When the display shows “
“ (TIME TO CLEAN
THE AIR FILTER), clean the filter(s). (Refer to
MAINTENANCE)

15.10 Self Diagnosis
In the unlikely event that a fault develops with the air
conditioner the microprocessor in the indoor and
outdoor units will diagnose the fault (where possible),
display a unique fault code on the remote controller
(see below) and flash the OPERATION INDICATOR (2)
on and off. If this occurs take a note of the fault code
(eg. A1) and contact your installer. This code will
indicate to the installer / repairer what the problem
may be.

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 (ie. 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.
IMPORTANT!
