ss
ss
sMulti system air conditioner (Outdoor unit: MXZ series) can con-
nect two or more indoor units with one outdoor unit. According to
the capacity, two or more units can operate simultaneously.
•When you try to operate two or more indoor units with one outdoor unit
simultaneously, one for the cooling and the other for heating, the opera-
tion mode of the indoor unit that operates earlier is selected. The other
indoor units that will start the operation later cannot operate, indicating
an operation state in flashing.
In this case, please set all the indoor units to the same operation mode.
•There might be a case that the indoor unit, which is operating in
(AUTO) mode. Cannot change over to the operating mode (COOL ↔
HEAT) and becomes a state of standby.
•When indoor unit starts the operation while the defrosting of outdoor
unit is being done, it takes a few minutes (max. about 15 minutes) to
blow out the warm air.
•In the heating operation, though indoor unit that does not operate may
get warm or the sound of refrigerant flowing may be heard, they are not
malfunction. The reason is that the refrigerant continuously flows into it.
Automatic operation
■According to a set temperature, cooling operation starts if the room tem-
perature is too hot and heating operation starts if the room temperature
is too cold.
■During automatic operation, if the room temperature changes and re-
mains 2 °C or more above the set temperature for 15 minutes, the air
conditioner switches to cooling mode. In the same way, if the room tem-
perature remains 2 °C or more below the set temperature for 15 min-
utes, the air conditioner switches to heating mode.

■Indicates that the filter needs cleaning.
Clean the filter.
■When resetting “FILTER”display
When the [FILTER] button is pressed two times successively after
cleaning the filter, the display goes off and is reset.
Note:
●When two 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 filter display goes off, the cumula-
tive 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 dirti-
ness depends on the environmental conditions, clean the filter accordingly.
●The filter cleaning period cumulative time differs with the model.
●This indication is not available for wireless remote controller.

sCleaning the filters
•Clean the filters using a vacuum cleaner. If you do not have a vacuum
cleaner, tap the filters against a solid object to knock off dirt and dust.
•If the filters are especially dirty, wash them in lukewarm water. Take care
to rinse off any detergent thoroughly and allow the filters to dry com-
pletely before putting them back into the unit.
9. Care and Cleaning
Caution:
•Do not dry the filters in direct sunlight or by using a heat source,
such as an electric heater: this may warp them.
•Do not wash the filters in hot water (above 50°C), as this may warp
them.
•Make sure that the air filters are always installed. Operating the
unit without air filters can cause malfunction.
Caution:
•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 filters using the methods shown in the following sketches.
ss
ss
sFilter removal
Caution:
•In removing the filter, 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 filter is removed, do not touch the metallic parts inside
the indoor unit, otherwise injury may result.
10. Trouble Shooting
Having trouble?
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 tem-
perature is reached.
A flowing 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.
Water or vapor is emitted from the outdoor unit.
The operation indicator does not appear in the remote controller display.
“ ” appears in the remote controller display.
When restarting the air conditioner soon after stopping it, it does not oper-
ate even though the ON/OFF button is pressed.
Here is the solution. (Unit is operating normally.)
■Clean the filter. (Airflow is reduced when the filter 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 sufficiently 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 de-
frosting operation. Normal operation should begin after approximately 10
minutes.
■These sounds can be heard when refrigerant is flowing in the air condi-
tioner or when the refrigerant flow 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.
■If the indoor temperature and the humidity are high, this condition may
occur when operation starts.
■During defrosting mode, cool airflow may blow down and appear like a
mist.
■During cooling mode, water may form and drip from the cool pipes and
joints.
■During heating mode, water may form and drip from the heat exchanger.
■During defrosting mode, water on the heat exchanger evaporates and
water vapor may be emitted.
■Turn on the power switch. “ ” will appear in the remote controller display.
■During central control, “ ” appears in the remote controller display and
air conditioner operation cannot be started or stopped using the remote
controller.
■Wait approximately three minutes.
(Operation has stopped to protect the air conditioner.)

■When cooling operation stops, the drain pump operates and then stops.
Wait approximately 3 minutes.
