Air does not flow immediately after

operation is started.

Mold in the room cannot be inhibited

even after performing the air

conditioner drying operation.

The interior of the indoor unit seems

to be still damp even after performing

the air conditioner drying operation.

Even if the air conditioner drying is

performed using the remote controller

during the unit operation or timer

programming, the air conditioner drying

operation does not start.

Preliminary operation is performed for one minute

when the power switch is turned on and heating

or dehumidifying is set. The operation lamp blinks

during this time for heating. This does not

indicate a fault.

Air conditioner drying operation is to dry the

interior of the indoor unit to inhibit the growth of

mold. It is not to inhibit the mold growth in the

room.

Condition of the interior of the indoor unit varies

depending on usage of the unit and condition of

the indoor unit. If it is not dried after the first try,

perform the drying more than one time for better

effect.

To perform the air conditioner drying, stop the

unit operation or programming beforehand.

Check to see if warm (cool) air is being short-

circuited behind the lattice door. A short-circuit is

likely to occur when the deflector position is not

appropriate, the lattice does not have a big

enough opening, and/or the unit is installed in the

inner part. Install the unit as near the lattice door

as possible.

When the damper is switched, scrambing of air

will occur brtween the top and bottom outlets due

to the set fan speed during switching and filter

clogged state, which, may generate some sound.

The unit is operated after built-in

installation (behind the lattice door). It

turns off for a long time and the room

is not warmed(cooled).

Strange sound is occasionally heard

from the bottom air outlet.
