Operating the remote controller
●
To use the remote controller, aim the transmitter at the indoor
unit. If there is anything to block signals between the unit and
the remote controller, such as a curtain, the unit will not
operate.
●
Do not drop the remote controller. Do not get it wet.
●
The maximum distance for communication is about 7 m.
About the remote controller
●
Never expose the remote controller to direct sunlight.
●
Dust on the signal transmitter or receiver will reduce the
sensitivity. Wipe off dust with soft cloth.
●
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.
●
If the remote control signals happen to operate another
appliance, move that appliance to somewhere else, or
consult the shop.

the unit.
Fix the holder to a wall, a pillar, etc. with the
screws supplied with the holder.
Fit the claw of the holder into the bottom of
the remote controller, and push the remote
controller onto the wall.

About batteries
●
When replacing the batteries, use batteries of the same
type, and replace the two old batteries together.
●
When the system is not used for a long time, take the
batteries out.
●
When the operation display screen of the remote controller
is hard to see and the reception become hard, replace the
batteries with new AAA batteries.
●
The attached batteries are provided for the initial use of
the system.
The usable period of the batteries may be short depending
on the manufactured date of the air conditioner.

Tips for saving energy
●
Be careful not to cool 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
●
Cover windows with a blind or a curtain.
Blocking sunlight and air from outdoors increases the
cooling effect.
●
Clogged air filters cause inefficient operation and waste
energy. Clean them once in about every two weeks.
●
Holding down (
) or (
) button
rapidly increases or decreases the time display.
Please note-
●
The air conditioner always consumes 15 ~ 35 watts of
electricity even while it is not operating.
●
If you are not going to use the air conditioner for a long
period, for example in spring or autumn, turn the breaker
OFF.
●
Use the air conditioner in the following conditions.

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.

Notes on POWERFUL operation
●
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.
●
In DRY mode
The temperature setting is lowered by 1˚C and the air flow rate
is slightly increased.
●
In FAN mode
The air flow rate is fixed to the maximum setting.

POWERFUL
Operation
●
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.
●
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 for Multi
System
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.

Precautions for outdoor unit connected to RMK(X)140
•
In heating operation, when all indoor units are stopped, the
outdoor unit stops its operation automatically after 5 minutes.
This is a part of preparation process for the next operation,
not a failure.
•
In heating operation, no warm air may come out temporarily.
This is for an oil recovery operation performed at certain time
intervals, not a failure.
•
In simultaneous operation at two or more rooms, when heating
operation is performed at one room, cooling operation cannot
be performed at other rooms. Whichever mode selected first
is preferred.
