Your MITSUBISHI ELECTRIC product is designed and manufactured with high quality materials and components which can be
recycled and/or reused. This symbol means that electrical and electronic equipment, batteries and accumulators, at their end-of-life,
should be disposed of separately from your household waste. If a chemical symbol is printed beneath the symbol (Fig. 1), this chemi-
cal symbol means that the battery or accumulator contains a heavy metal at a certain concentration.
This will be indicated as follows: Hg: mercury (0,0005%), Cd: cadmium (0,002%), Pb: lead (0,004%)
In the European Union there are separate collection systems for used electrical and electronic products, batteries and accumula-

Note(Onlyforwirelessremotecontroller):
■When using the wireless remote controller, point it towards the receiver on the indoor unit.
■If the remote controller is operated within approximately two minutes after power is sup-
plied to the indoor unit, the indoor unit may beep twice as the unit is performing the initial
automatic check.
■ The indoor unit beeps to conrm that the signal transmitted from the remote controller has
been received. Signals can be received up to approximately 7 meters in a direct line from
the indoor unit in an area 45° to the left and right of the unit. However, illumination such
as uorescent lights and strong light can affect the ability of the indoor unit to receive sig-
nals.
■ If the operation lamp near the receiver on the indoor unit is ashing, the unit needs to be
inspected. Consult your dealer for service.
■Handle the remote controller carefully! Do not drop the remote controller or subject it to
strong shocks. In addition, do not get the remote controller wet or leave it in a location with
high humidity.
■To avoid misplacing the remote controller, install the holder included with the remote control-
ler on a wall and be sure to always place the remote controller in the holder after use.

Informationformultisystemairconditioner(Outdoor
unit:MXZseries)
►Multisystemairconditioner(Outdoorunit:MXZseries)can
connecttwoormoreindoorunitswithoneoutdoorunit.According
tothecapacity,2ormoreunitscanoperatesimultaneously.
• When you try to operate 2 or more indoor units with 1 outdoor unit
simultaneously, one for the cooling and the other for heating, the
operation 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 blinking.
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 owing may be heard, they are
not malfunction. The reason is that the refrigerant continuously ows
into it.
Automaticoperation
■According to a set temperature, cooling operation starts if the room
temperature is too hot and heating operation starts if the room
temperature is too cold.
■During automatic operation, if the room temperature changes and
remains 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
temperature remains 2 °C or more below the set temperature for 15

When the is displayed on the
Main display in the Full mode, the
system is centrally controlled and
the lter sign cannot be reset.
If two or more indoor units are connected, filter cleaning timing for
each unit may be different, depending on the lter type.
The icon will appear when the lter on the main unit is due for
cleaning.
When the lter sign is reset, the cumulative operation time of all units
will be reset.
The icon is scheduled to appear after a certain duration of op-
eration, based on the premise that the indoor units are installed in a
space with ordinary air quality. Depending on the air quality, the lter
may require more frequent cleaning.
The cumulative time at which filter needs cleaning depends on the
model.
