Never inspect or service the unit by yourself. Contact a qualified service person to perform this work.

The heat exchanger fins are sharp enough to cut. To avoid injury, wear gloves or cover the fins while working around them.

Do not place items under the indoor unit as they may be damaged by condensates that may form if the humidity is above 80% or if the drain outlet gets blocked.

Do not wipe the controller operation panel with benzine, thinner, or chemical dust cloth, as the panel may get discolored or the coating can peel off. If it is heavily dirty, soak a cloth in water-diluted neutral detergent, squeeze it well, and wipe the panel clean. Then, wipe it with another dry cloth.

This is to protect the air conditioner. You should wait for about 3 minutes.

In HEAT operation, the air conditioner may be warming up (wait 1 to 4 minutes) or performing defrosting operation, during which hot air does not flow out of the indoor unit.

The system is taking away the frost on the outdoor unit. You should wait for about 4 to 12 minutes.

This happens when the air in the room is cooled into mist by the cold airflow during cooling operation.

This happens when smells of the room, furniture, or cigarettes are absorbed into the unit and discharged with the airflow. If this happens, it is recommended to have the indoor unit washed by a technician. Consult your dealer.

After operation is stopped, the outdoor fan continues rotating for another 1 minute for system protection. While the air conditioner is not in operation, if the outdoor temperature is very high, the outdoor fan starts rotating for system protection.

Check if the air filters are clean or if there is anything blocking the air inlet or outlet of the indoor and outdoor units. Clean the air filters or remove all obstacles, turn the circuit breaker OFF, then turn it ON again and try operating the DAIKIN FFQ18W2VJU9 with the remote controller. If the lamp still blinks, call your dealer.

Are the airflow rate and the air direction set appropriately?

When more than one indoor unit is operating, priority is given to the first unit that was turned on. Set the units that are turned on later to the same operation mode as the first unit. Otherwise, they will enter the standby state, and the centralized control icon will light up on the wired remote controller.

Yes, COOL, DRY, and FAN operations may be used at the same time on a multi system DAIKIN FFQ18W2VJU9.

Normally, the operation mode in the room where the unit is first started is given priority. However, if the operation mode of the first room is FAN operation, then using HEAT operation in any room after this will give priority to HEAT operation. In this situation, the indoor unit operating in FAN mode will switch to standby.

NIGHT QUIET mode is only available for COOL operation on the DAIKIN FFQ18W2VJU9. This mode requires initial programming during installation and reduces the operation noise of the outdoor unit during night-time hours.

No, the COOL/HEAT mode lock cannot be activated together with the priority room setting on the DAIKIN FFQ18W2VJU9.

The priority room setting for the DAIKIN FFQ18W2VJU9 requires initial programming during installation.
