When using the wireless remote controller, point it towards the receiver on the indoor unit. If the remote controller is operated within approximately two minutes after power is supplied

to the indoor unit, the indoor unit may beep twice as the unit is performing the initial automatic check.

The indoor unit beeps to confirm that the signal transmitted from the remote controller has

been received. Signals can be received up to approximately 23ft.(7m) in a direct line from the indoor unit in an area 45° to the left and right of the unit. However, illumination such as ﬂ uores- cent lights and strong light can affect the ability of the indoor unit to receive signals.

If the operation lamp near the receiver on the indoor unit is blinking, the unit needs to be in-

spected. Consult your dealer for service.

Handle the remote controller carefully! Do not drop the remote controller or subject it to strong

shocks. In addition, do not get the remote controller wet or leave it in a location with high humidity.

To avoid misplacing the remote controller, install the holder included with the remote controller

on a wall and be sure to always place the remote controller in the holder after use.

When resetting “FILTER” display

When the [FILTER] button is pressed two times successively after

cleaning the ﬁ lter, the display goes off and is reset.

Note:

When 2 or more different types of indoor unit are controlled, the

cleaning period differs with the type of filter. When the master unit cleaning period arrives, “FILTER” is displayed. When the ﬁ l- ter display goes off, the cumulative time is reset.

“FILTER” indicates the cleaning period when the air conditioner

was used under general indoor air conditions by criteria time. Since the degree of dirtiness depends on the environmental con-

ditions, clean the ﬁ lter accordingly. The ﬁ lter cleaning period cumulative time differs with the model. This indication is not available for wireless remote controller.

Cleaning the ﬁ lters

• Clean the ﬁ lters using a vacuum cleaner. If you do not have a vacuum cleaner, tap the ﬁ lters against a solid object to knock off dirt and dust.

• If the ﬁ lters are especially dirty, wash them in lukewarm water. Take care to rinse off any detergent thoroughly and allow the ﬁ lters to dry completely before putting them back into the unit.

Caution:

• In removing the ﬁ lter, precautions must be taken to protect your eyes from dust. Also, if you have to climb up on a stool to do the job, be careful not to fall.

• When the ﬁ lter is removed, do not touch the metallic parts inside the indoor unit, otherwise injury may result.

Pull both the bottom corners of the intake grille to open the grille,

then lift the ﬁ lter.

Caution:

• Do not dry the ﬁ lters in direct sunlight or by using a heat source, such as an electric heater: this may warp them.

• Do not wash the ﬁ lters in hot water (above 50°C, 122°F), as this may warp them.

• Make sure that the air ﬁ lters are always installed. Operating the unit without air ﬁ lters can cause malfunction.

• Before you start cleaning, stop operation and turn OFF the power supply.

• Indoor units are equipped with filters to remove the dust of sucked-in air. Clean the ﬁ lters using the methods shown in the following sketches.

11. Trouble Shooting

Having trouble? Here is the solution. (Unit is operating normally.)

Air conditioner does not heat or cool well.

When heating operation starts, warm air does not blow from the indoor unit soon.

During heating mode, the air conditioner stops before the set room temperature is reached.

Airﬂ ow direction changes during operation or airﬂ ow direction cannot be set.

When the airﬂ ow direction is changed, the vanes always move up and down past the set position before ﬁ nally stopping at the position.

A ﬂ owing water sound or occasional hissing sound is heard.

A cracking or creaking sound is heard.

The room has an unpleasant odor.

A white mist or vapor is emitted from the indoor unit. If the indoor temperature and the humidity are high, this condition may

Clean the ﬁ lter. (Airﬂ ow is reduced when the ﬁ lter is dirty or clogged.) Check the temperature adjustment and adjust the set temperature. Make sure that there is plenty of space around the outdoor unit. Is the

indoor unit air intake or outlet blocked?

Has a door or window been left open? Warm air does not blow until the indoor unit has sufﬁ ciently warmed up.

When the outdoor temperature is low and the humidity is high, frost

may form on the outdoor unit. If this occurs, the outdoor unit performs a defrosting operation. Normal operation should begin after approximately10 minutes.

During cooling mode, the vanes automatically move to the horizontal

(down) position after 1 hour when the down (horizontal) airﬂ ow direction is selected. This is to prevent water from forming and dripping from the vanes.

During heating mode, the vanes automatically move to the horizontal

airﬂ ow direction when the airﬂ ow temperature is low or during defrost- ing mode.

When the airﬂ ow direction is changed, the vanes move to the set posi-

tion after detecting the base position.

These sounds can be heard when refrigerant is ﬂ owing in the air condi-

tioner or when the refrigerant ﬂ ow is changing.

These sounds can be heard when parts rub against each due to expan-

sion and contraction from temperature changes.

The indoor unit draws in air that contains gases produced from the

walls, carpeting, and furniture as well as odors trapped in clothing, and then blows this air back into the room.

occur when operation starts.

During defrosting mode, cool airﬂ ow may blow down and appear like a

mist.
