I. 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 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 fire 

hazard.

If a safety device such as a fuse, a breaker, or an 
earth leakage breaker frequently actuates;

Measure: 

 Do not turn on the main power switch.

If the ON/OFF switch does not properly work;

Measure: 

 Turn off the main power switch

If water leaks from unit.

Measure:

  Stop the operation.

If the display “ 

 ” (INSPECTION), “UNIT No.”, 

and the OPERATION lamp flash and the 
“MALFUNCTION CODE” appears.

Measure:

 Notify your Daikin dealer and inform

                 him/her of the display.

II. If the system does not properly operate except 

for the above mentioned case, and none of the 

above mentioned malfunctions is evident, 

investigate the system according to the 

following procedures.

1. If the system does not operate at all.

Check if there is a power failure.
Wait until power is restored. If power failure 
occurs during operation, the system
automationcally restarts immediately after
the power supply recovers.

Check if no fuse has blown.
Turn off the power supply.

Check if the breaker is blown.
Turn the power on with the breaker switch in 
the off position.
Do not turn the power on with the breaker 
switch in the trip position.
(Contact your dealer.)

2. If the system stops operating after operating 

the system.

Check if the air inlet or outlet of outdoor or indoor 
unit is blocked by obstacles.
Remove the obstacle and make it well-ventilated.

Obstacles decrease the airflow rate, and 

cause performance decrease and breakage 

when discharged air is suctioned. They 

cause a waste of electricity, and that may 

stop the devices.

VI. DUST FROM THE UNITS

Dust may blow out from the unit after starting 

operation from long resting time.

Dust absorbed by the unit blows out.

VII. THE UNITS GIVE OFF ODORS

The unit absorbs the smell of rooms, furniture, 
cigarettes, etc., and then emits them.
If odor is a concern, set the airflow rate to gentle 
or no airflow when the indoor temperature 
reaches the set temperature.
For details, contact your Daikin dealer.

VIII.THE UNIT DOES NOT COOL EFFECTIVELY

Program dry operation.

Program dry operation is designed to lower the 
room temperature as little as possible.
Lower the room temperature using cooling 
operation, and then use program dry operation.

Read through characteristics of the cooling 

operation, characteristics of the heating 

operation, and characteristics of the program

dry operation. (Refer to page 6, 7)

IX. THE LIQUID CRYSTAL OF THE REMOTE 

CONTROLLER SHOW “

It happens immediately after the main power 

supply switch is turned on.

This shows that the remote controller is in normal 
condition. 
This continues temporary.
