Smells

Whenever the air conditioner is turned on, it stinks.

There are no components in the air conditioner sending out chemical smells. But, when the air con-
ditioner is turned on, other smell sources are sucked into the air conditioner and get out of it. So, find
and root out the smell sources. Generally, when the drain hose is taken out to the washing room or
there are sources of smells such as a diaper bin, a shoe shelf or a socks bin, bad smells generate.
Also, it occurs where glass cleaners or air fresheners are used; when they are sucked in interacting
with dusts and moistures inside, bad smells generate. These kinds of organic materials noxious to
human bodies. So, we recommend against the use of them.

Whenever the air conditioner is turned on, it smells sour.

When  the  room  is  papered  recently,  its  paste  smells  would  be  sucked  inside.  Also,  when  the  air
conditioner  is  installed  in  the  study  room  of  young  boys  loving  sweat-generating  activities  such  as
the basketball, excessive sweats evaporate and get sucked into the air conditioner resulting in bad
smells. So, find and root out the problem or refresh the room frequently.

Whenever the air conditioner is turned on, it smells musty.

It is due to the improper keeping of the product after its use. When keeping the product, dry up the
inside with the operation of Ventilation to prevent must. When the product is kept without drying up
the inside with Ventilation, mold would grow inside resulting in must. So, open the windows and
switch on the Ventilation function to get rid of the saturated smell inside.

Whenever the air conditioner is turned on, it sends out bad smells such as stale smells.

It occurs generally when there are pet animals in the house. Their smells stay at the same place. But,
when the air conditioner is turned on, the air gets circulated resulting in the circulation of the smells.

Operation

It won't start.

There is a power failure or it is plugged out. Also, check if the power distribution panel is switched off.

It goes off during operation.

When the hot air does not escape properly, it goes off during operation. It occurs when it does not
ventilate properly because the outdoor unit is covered, the back of the outdoor unit is blocked by a
cardboard or a plywood panel, and the front of the outdoor unit is blocked by the closed window or
other obstacles. Clear the above obstacles from the outdoor unit.

It generally works properly. But, when it's considerably hot, it goes off during operation.

It occurs when the outdoor unit is exposed to direct sunlight and the hot air does not escape properly.
Set up a sun blind over the outdoor unit and clear the neighboring obstacles from the outdoor unit to
provide good ventilation. When it goes off frequently during a heat wave, it would prevent the turn-
off  and  increase  the  cooling  capacity  cleaning  the  outdoor  unit  or  spraying  some  water  to  the  heat
exchanger.

The remote controller won't operate.

When the batteries run out or the transmitter or receiver of the remote controller is blocked by obsta-
cles, change the batteries or keep the obstacles away from the controlling area. Also, the remote
controller may not work under intensive light from a 3-wave length lamp or a neon sign due to the
EMI. In this case, take the remote controller closer to the receiver.
