 Cleaning the drain pan
• Clean the drain pan periodically, or drain piping may be clogged with dust and may result in water leakage.
Ask your DAIKIN dealer to clean them.
• Prepare a cover locally to prevent any dust in the air around the indoor unit from getting in the drain pan, if
there is a great deal of dust present.
CAUTION
• Do not operate the air conditioner without filters, this to avoid dust accumulation inside the
unit.
• Do not remove the air filter except when cleaning.
Unnecessary handling may damage the filter.
• 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.
• Operation with dusty air filters lowers the cooling and heating capacity and wastes energy.
• The suction grille is option.
• Do not use water or air of 50°C or higher for cleaning air filters and outside panels.
• Ask your DAIKIN dealer how to clean it.
Check
Check that the base, stand and other fittings of the outdoor unit are not decayed or corroded.
Check that nothing blocks the air inlets and the outlets of the indoor unit and the outdoor unit.
Check that the drain comes smoothly out of the drain hose during COOL or DRY operation.
• If no drain water is seen, water may be leaking from the indoor unit. Stop operation and consult the
service shop if this is the case.
 Before a long idle period
1. Operate the “FAN only” for several hours on a fine day to dry out the inside.
• Press “MODE selector button” and select “FAN” operation.

TROUBLE SHOOTING
Trouble Shooting
These cases are not troubles.
The following cases are not air conditioner troubles but have some reasons. You may just continue using it.
Case
Explanation
Operation does not start soon.
• When ON/OFF button was
pressed soon after
operation was stopped.
• When the mode was
reselected.
• This is to protect the air conditioner.
You should wait for about 3 minutes.
Hot air does not flow out soon
after the start of heating
operation.
•
The air conditioner is warming up. You should wait for 1 to 4
minutes.
(The system is designed to start discharging air only after it
has reached a certain temperature.)
The heating operation stops
suddenly and a flowing sound
is heard.
•
The system is taking away the frost on the outdoor unit.
You should wait for about 3 to 8 minutes.
The outdoor unit emits water or
steam.
 In HEAT mode
• The frost on the outdoor unit melts into water or steam
when the air conditioner is in defrost operation.
 In COOL or DRY mode
• Moisture in the air condenses into water on the cool
surface of outdoor unit piping and drips.
Mists come out of the indoor
unit.
 This happens when the air in the room is cooled into mist by
the cold air flow during cooling operation.
The indoor unit gives out odour.  This happens when smells of the room, furniture, or
cigarettes are absorbed into the unit and discharged with the
air flow.
(If this happens, we recommend you to have the indoor unit
washed by a technician. Consult the service shop where you
bought the air conditioner.)
The outdoor fan rotates while
the air conditioner is not in
operation.
 After operation is stopped:
• The outdoor fan continues rotating for another 30
seconds for system protection.
 While the air conditioner is not in operation:
• When the outdoor temperature is very high, the outdoor
fan starts rotating for system protection.
The operation stopped
suddenly.
(OPERATION lamp is on.)
 For system protection, the air conditioner may stop
operating on a sudden large voltage fluctuation.
It automatically resumes operation in about 3 minutes.

Check again.
Please check again before calling a repair person.
Case
The air conditioner does not
operate.
(OPERATION lamp is off.)
Check
•
•
•
•
Hasn’t a breaker turned OFF or a fuse blown?
Isn’t it a power failure?
Are batteries set in the remote controller?
Is the timer setting correct?
Cooling (Heating) effect is poor. • Are the air filters clean?
• Is there anything to block the air inlet or the outlet of the
indoor and the outdoor units?
• Is the temperature setting appropriate?
• Are the windows and doors closed?
• Are the air flow rate and the air direction set appropriately?
Operation stops suddenly.
(OPERATION lamp blinks.)
• Are the air filters clean?
• Is there anything to block the air inlet or the outlet of the
indoor and the outdoor units?
Clean the air filters or take all obstacles away and turn the
breaker OFF. Then turn it ON again and try operating the air
conditioner with the remote controller. If the lamp still blinks,
call the service shop where you bought the air conditioner.
• Are operation modes all the same for indoor units
connected to outdoor units in the multi system?
If not, set all indoor units to the same operation mode and
confirm that the lamps blink.
Moreover, when the operation mode is in “AUTO”, set all
indoor unit operation modes to “COOL” or “HEAT” for a
moment and check again that the lamps are normal.
If the lamps stop blinking after the above steps, there is no
malfunction.
