(Risk of re)
This symbol is only for R32 refrigerant. The type of the refrigerant used is written on the nameplate on the outdoor unit.
R32 refrigerant is ammable. If the refrigerant leaks, or comes in contact with re or parts that generate heat, it may create
harmful gas and pose a risk of re.
Read the OPERATION MANUAL carefully before operation.
Service personnel are required to carefully read the OPERATION MANUAL and INSTALLATION MANUAL before operation.

otherrefrigerant,anddonotallowairtoremaininthelines.
- If air is mixed with the refrigerant, then it may cause abnormal high
pressure in the refrigerant lines, resulting in an explosion and other
hazards.
- The use of any refrigerant other than that specied for the
system will cause mechanical failure, system malfunction, or
unit breakdown. In the worst case, this could lead to a serious
impediment to securing product safety.
- It may also be in violation of applicable laws.
- MITSUBISHI ELECTRIC CORPORATION cannot be held
responsible for malfunctions or accidents resulting from the use of
the wrong type of refrigerant.

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
supplied 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 a󰀨ect the ability of the indoor unit to receive
signals.
■ 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
controller on a wall and be sure to always place the remote controller in the holder after
use.

3.Operation
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,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
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 ashing.
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
minutes, the air conditioner switches to heating mode.
Cooling mode 15 minutes (switches
from heating to cooling)
Set temperature +2°C
Set temperature
Set temperature -2°C
15 minutes (switches
from cooling to heating )
■ Because the room temperature is automatically adjusted in order to
maintain a xed e󰀨ective temperature, cooling operation is performed
a few degrees warmer and heating operation is performed a few
degrees cooler than the set room temperature once the temperature is
reached (automatic energy-saving operation).
