System relocation
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.
Note for Multi
System
●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.
●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.

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 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-seetting level.
●If you do not like AUTO operation, you can
select manually, you like the mode and setting.

Trouble Shooting
●●
●●
●These cases are not troubles.
The following cases are not air conditioner troubles but have some reasons. You may just continue
using it.
Case
Operation does not start soon.
●When ON/OFF button was
pressed soon after operation
was stopped.
●When the mode was reselected.
Hot air does not flow out soon
after the start of heating
operation.
The heating operation stops
suddenly and a flowing sound is
heard.
The outdoor unit emits water or
steam.
Mists come out of the indoor unit.
The indoor unit gives out odour.
The outdoor fan rotates while the
air conditioner is not in operation.
The operation stopped suddenly.
(OPERATION lamp is on)
Explanation
●This is to protect the air conditioner.
You should wait for about 3 minutes.
●The air conditioner is warming up.You should wait for 1 to 4 minutes.
(The system is designed to start discharging air only after it has reached
a certain temperature.)
●The system is taking away the frost on the outdoor unit.
You should wait for about 3 to 10 minutes.
■In HEAT mode
•The frost on the outdoor unit melts into water or steam when the air
conditioner is in defrost operation.
■In COOL or DRY mode
•Moisture in the air condenses into water on the cool surface of
outdoor unit piping and drips.
■This happens when the air in the room is cooled into mist by the cold
air flow during cooling operation.
■This happens when smells of the room, furniture, or cigarettes are
absorbed into the unit and discharged with the air flow.
(If this happens, we recommend you to have the indoor unit washed
by a technician. Consult the service shop where you bought the air
conditioner.)
■After operation is stopped:
•The outdoor fan continues rotating for another 60 seconds for system
protection.
■While the air conditioner is not in operation:
•When the outdoor temperature is very high, the out door fan starts
rotating for system protection.
■For system protection, the air conditioner may stop operating on a
sudden large voltage fluctuation.
It automatically resumes operation in about 3 minutes.

Case
The air conditioner does not
operate.
(OPERATION lamp is off)
Cooling or Heating effect is
poor.
Operation stops suddenly.
(OPERATION lamp blinks.)
An abnormal functioning
happens during operation.
Check
●Hasn’t a breaker turned OFF or a fuse blown?
●Isn’t it a power failure?
●Are batteries set in the remote controller?
●Is the timer setting correct?
●Are the air filters clean?
●Is there anything to block the air inlet or the outlet of the indoor and the
outdoor units?
●Is the temperature setting appropriate?
●Are the windows and doors closed?
●Are the air flow rate and the air direction set appropriately?
●Are the air filters clean?
●Is there anything to block the air inlet or the outlet of the indoor and the
outdoor units?
Clean the air filters or take all obstacles away and turn the breaker OFF.
Then turn it ON again and try operating the air conditioner with the remote
controller. If the lamp still blinks, call the service shop where you bought the
air conditioner.
●Are operation modes all the same for indoor units connected to outdoor
units in the multi system?
If not, set all indoor units to the same operation mode and confirm that the
lamps blink.
Moreover, when the operation mode is in “AUTO”, set all indoor unit opera-
tion modes to “COOL”or “HEAT”for a moment and check again that the
lamps are normal.
If the lamps stop blinking after the above steps, there is no malfunction.
(See page 12.)
