operate.
l
Do not drop the remote controller. Do not get it wet.
l
The maximum distance for communication is about 7 m.

About the remote controller
l
Never expose the remote controller to direct sunlight.
l
Dust on the signal transmitter or receiver will reduce the
sensitivity. Wipe off dust with soft cloth.
l
Signal communication may be disabled if an
electronic-starter-type fluorescent lamp (such as
inverter-type lamps) is in the room. Consult the shop if that
is the case.
l
If the remote control signals happen to operate another
appliance, move that appliance to somewhere else, or
consult the shop.

Five levels of air flow rate setting from
"
" to "
"plus "

l
At smaller air flow rates, cooling or heating effect is also
smallwer.
n
To change the air flow direction:
(See page 10.)
NOTE
<Note on HEAT mode operation>
Since this air conditioner heats the room by taking heat from
outdoor air to indoors, the heating capacity becomes smaller in
lower outdoor temperatures. If the heating effect is insufficient, it
is recommended to use another heating appliance in
combination with the air conditioner.
The heat pump system heats the room by circulating hot air
around all parts of the room. After the start of heating operation,
it takes some time before the room gets warmer.
In heating operation, frost may occur on the outdoor unit and
lower the heating capacity. In that case, the system switches
into defrosting operation to take away the frost. During
defrosting operation, hot air does not flow out of indoor unit.
<Note on DRY mode operation>
This operation dehumidifies the indoor air when it is humid.
<Note on AUTO operation>
In AUTO operation, the system selects a temperature setting
and an appropriate mode (COOL or HEAT) based on the room
temperature at the start of the operation.
The system automatically reselects setting at a regular interval to
bring the room temperature to user-setting level.
If you do not like AUTO operation, you can select manually,
you like the mode and setting.
Preparation Before Operation

Setting the air purifying filters
1
Open the front grille .
l
Hold the grille by the tabs on the two sides and lift it until
it stops with a click. (about 60˚)
2
Pull out the air filters.
l
Push upwards the tab at
the center of each air
filter, then pull it down.
3
Set the air purifying filters.
l
Attach an air purifying filter to each air filter.
(See page 14 "Care and cleaning")
4
Set the air filters in their original
positions and close the front grille .
l
Operation without air filters may result in troubles as dust
will accumulate inside the indoor unit.
NOTE
Tips for saving energy
l
Be careful not to cool (heat) the room too much.
Keeping the temperature setting at a moderate level helps
save energy.
Recommended temperature setting
For cooling: 26˚C – 28˚C
For heating: 20˚C – 24˚C
l
Cover windows with a blind or a curtain.
Blocking sunlight and air from outdoors increases the
cooling (heating) effect.
l
Clogged air filters cause inefficient operation and waste
energy. Clean them once in about every two weeks.
POWERFUL
Operation
POWERFUL operation quickly maximizes the cooling
effect in any operation mode. You can get the maximum
capacity with a touch of a button.
l
Pressing the (POWERFUL) button during operation starts
POWERFUL operation.
l
POWERFUL operation ends in 20 minutes. Then the system
automatically operates again with the settings which were used
before POWERFUL operation.

Notes on POWERFUL operation
l
In COOL and HEAT mode
To maximize the cooling and heating effect, the capacity of
outdoor unit must be increased and the air flow rate be fixed to
the maximum setting.
The temperature and air flow settings are not variable.
l
In DRY mode
The temperature setting is lowered by 3˚C and the air flow rate
is slightly increased.
l
In FAN mode
The air flow rate is fixed to the maximum setting.

Precedence-room setting
When setting the preference-room during installation, the
indoor unit's operation mode always takes priority.
When the precedence-setting room unit is operated in
POWERFUL mode, there are times that air conditioners in other
rooms will temporarily stop in order to centralize power to the
unit in the room.
Please adjust the precedence-room setting to match your life
style. Moreover, for precedence-room settings, please consult
the service shop where you bought the unit.
Precedence-room setting is applied to only 4MX80, 4MK90.
l
COOL/HEAT mode
This mode is used to set the unit to only cool or heat. For
information on using this mode, consult the service shop where
you bought the unit.
COOL/HEAT mode is applied to only 4MX80, 4MK90.
NOTE
<Note for heat pump multi system>
When two or more indoor units have no precedence-room
settings and are set to modes that differ from each other, the
indoor unit which is operated first activates, while the other
indoor unit does not activate and the OPERATION lamp blinks.
(This is not a malfunction.)
An indoor unit that is not in operation will automatically start
and operate in the mode in which a previously operated indoor
unit was stopped. However, if the unit in operation provides
only COOL and DRY modes, simultaneous operation is
possible.
