Operation with the Remote Control Unit (continued)

• After the cooling or drying operation has stopped, the indoor fan runs
for about 30 seconds to dry out the inside of the air conditioner. (The
operating lamps remain off.) The flap closes after the fan has
stopped.

• If the room temperature rises above the temperature setting during a
drying operation, the unit performs similar operation to cooling, and
when the room temperature approaches the temperature setting, it
performs the humidity-priority drying operation.

• The drying operation does not serve to raise the room temperature.
(When the outside air temperature is low or when the heat quantity
inside the room is low, the room temperature will not rise.)

• A change made to the temperature setting remains stored in the
memory even after operation has stopped.

• If the temperature setting is lowered during a drying operation so that
the unit has switched to a cooling operation, the outdoor unit shuts
down for 3 minutes. (This happens only when one indoor unit is
used.)

• When the unit is running in the drying operation mode while the
temperature setting is higher than the room temperature, the
humidity may not be reduced. In a case like this, select a temperature
setting which is lower than the current room temperature, and
perform the drying operation.

NOTE This appliance has a built-in 3-minute time delay circuit to ensure reliable

operation. When the operation button is pressed, the compressor will
start running within three minutes. In the event of power failure, the unit
will stop.

During a cooling or drying operation

• The room is cooled down for 15 minutes by cooling at a slightly lower
temperature than usual, and the fan speed is set to the highest fan
speed setting.

• When the unit is used continuously for 15 minutes, the temperature
setting has been reached during a cooling or heating operation or the
humidity setting has been reached during a drying operation (which is
only when one indoor unit is operated), operation will continue for
the next 5 minutes at a reduced power level, after which the regular
operation is restored.
If the setting is not reached in either case, regular operation is
restored immediately.

• After HIGH POWER operation has finished or when a HIGH POWER
operation has been canceled on the way and then reinstated, regular
operation is performed for about 5 minutes to protect the unit, and
then the HIGH POWER operation is performed.

• During HIGH POWER operations, the room temperature may not
coincide with the temperature setting.

indoor units

Tips for Energy Saving

Do not • Block the air intake and outlet of the unit. If they are obstructed, the

unit will not work well, and may be damaged.

• Let direct sunlight into the room. Use sunshades, blinds or curtains. If
the walls and ceiling of the room are warmed by the sun, it will take
longer to cool the room.

Do • Always try to keep the air filter clean. (Refer to “Care and Cleaning”.)

A clogged filter will impair the performance of the unit.

• To prevent conditioned air from escaping, keep windows, doors and
any other openings closed.

Adjusting the Airflow Direction

1. Horizontal The horizontal airflow can be adjusted by moving the vertical vanes with

your hands to the left or right.

When the humidity is high, the vertical vanes should be in the front
position during the cooling or dehumidifying operation. If the vertical
vanes are positioned all of the way to the right or left, condensation may
begin to form around the air vent and drip down.

2. V ertical The vertical airflow can be adjusted by moving the flap with the remote

control unit. Do not move the flap with your hands. Confirm that the
remote control unit has been turned on. Use the FLAP button to set either
the sweep function or one of the six airflow direction settings.

CAUTION

A. Sweep function

The flap starts moving up and down to
deliver air over the sweep range.

B. Setting the airflow manually

Referring to the above illustration, use the
FLAP button to set the airflow direction
within the range used during the heating,
cooling, or dehumidifying operation.

NOTE • The flap automatically closes when the unit is off.

• During the heating operation, the fan speed will be very low and the

flap will be in the horizontal position (position 6) until the air being
blown out of the unit begins to warm. Once the air warms up, the flap
position and fan speed change to the settings specified with the
remote control.

• Use the FLAP button on the remote control to adjust the position of
the flap. If you move the flap by hand, the factual flap position and the
flap position on the remote control may no longer match. If this
should happen, shut off the unit, wait for the flap to close, and then
turn on the unit again; the flap position will now be normal again.

• Do not have the flap pointed down during cooling and drying
operation. Condensation may begin to form around the air vent and
drip down.

Clean the casing and grille of the indoor unit with a vacuum cleaner
brush, or wipe them with a clean, soft cloth.

If these parts are stained, use a clean cloth moistened with a mild liquid
detergent. When cleaning the grille, be careful not to force the vanes out
of place.

1. Never use solvents, or harsh chemicals when cleaning the indoor
unit. Do not wipe the plastic casing using very hot water.

2. Some metal edges and the fins are sharp and may cause injury if
handled improperly; be especially careful when you clean these
parts.

3. The internal coil and other components of the outdoor unit must be
cleaned every year. Consult your dealer or service center.

Operation without the Remote
Control Unit

If you have lost the remote control unit or it has trouble, follow the steps
below.

1. When the air conditioner is not running
If you want to turn on the air conditioner, switch the operation selector to
the OFF position, and then to the ON position.

NOTE The set temperature and fan speed are automatically set at the

last selection before stopping.

2. When the air conditioner is running

the OFF position.

Care and Cleaning

1. For safety, be sure to turn the air conditioner off and also to
disconnect the power before cleaning.

2. Do not pour water on the indoor unit to clean it. This will damage
the internal components and cause an electric shock hazard.
