Description of “AUTO RESTART FUNCTION”
• These units are equipped with an auto restart function. When the main power is turned on, the air conditioner will start
operation automatically in the same mode as the one set with the remote controller before the shutoff of the main
power.
• If the unit was set to off with the remote controller before the shutoff of the main power, it will remain stopped even after
the main power is turned on.
• If the unit was in the emergency operation before the shutoff of the main power, it will start operation, when main power
comes on, in the same mode as the one set with the remote controller before the emergency operation.
• If the unit is operated in “I FEEL...” mode before power failure, the operation mode (COOL, DRY or HEAT) is not stored
in the memory. When the main power is turned on, the unit decides the operation mode by the initial room temperature
at restart and starts operation again.

In HEAT operation
• If the air conditioner absorbs too much heat from the air, it may be overloaded. Following a judgement made by the
microprocessor, the fan in the outdoor unit is automatically stopped to protect the air conditioner.
When the outdoor unit’s fan is stopped, frost may form on the outdoor unit, but this is not a problem.
In DRY operation
• The temperature control (temperature setting) cannot be done.
• The room temperature is slightly lowered in this operation mode.
■
The details of the display on the indoor unit are explained on page 6.
NOTE:
When the ambient temperature is too high, the room temperature may not reach the set temperature since the unit
operates to cool the room under a high load.
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. (Refer to the table of Operation Indicator lamp on page 6.)
In this case, please set all the indoor units to the same operation mode.
• When indoor unit starts the operation while the defrosting of outdoor unit is being done, it takes a few minutes (max. 10
minutes) to blow out the warm air.
• In the heating operation, the indoor unit that does not operate may get warm or the sound of refrigerant flowing may be
heard. This is not a malfunction since the refrigerant continuously flows into the indoor unit that does not operate.
NOTE:
• In the cooling operation, when the air conditioner is operated with setting the horizontal vane to
(4) or
(5) for 1 hour, the AIR FLOW direction is automatically set to horizontal to prevent condensed water
from dropping.
• Adjust the vertical AIR FLOW direction using the remote controller. If the horizontal vane is moved manually, it may
cause trouble.
• In the heating operation, if the air flow temperature is too low or when defrosting is being done, the horizontal vane
position is set to
(1).
Auto air flow direction control operation

• When the air flow temperature is too low, the air is
blown out horizontally.
• When the air flow temperature rises, the air is blown
out downwards.
(2) COOL, DRY
The air is blown out horizontally.
(3) FAN
The air is blown out downwards.
■
To change the horizontal direction of the air
flow, move the vertical vane manually.
Adjust the vane before operation starts.
Since the horizontal vane moves automatically, your
fingers may be caught.

What is “ECONO COOL”?
Swing air flow (change of air flow) makes you feel cooler than constant air flow. So, even though the set temperature is
automatically set 2°C higher, it is possible to perform cooling operation with keeping comfort. As a result, energy can be saved.
CAUTION:
Turn off the breaker or disconnect the power supply plug
when the air conditioner is not going to be used for a
long time.
Dirt may collect and this may cause a fire.

WARNING :
If the air conditioner operates but does not cool or heat (depending on model) the room, consult your dealer since
there may be a refrigerant leak. Be sure to ask the service representative whether there is refrigerant leakage or not
when repairs are carried out.
The refrigerant charged in the air conditioner is safe. Refrigerant normally does not leak, however, if refrigerant gas
leaks indoors, and comes into contact with the fire of a fan heater, space heater, stove, etc., harmful substances will be
generated.
Operating sound considerations
• Do not put an object around the air outlet of the outdoor unit. This may lower the capacity or increase the volume of the
operating sound.
• If an abnormal sound is heard during operation, consult your dealer.
Relocation
Electrical work
• When the air conditioner is to be removed or re-installed because of rebuilding, moving, etc., special techniques and work
are required.
• Provide an exclusive circuit for the power supply of the air conditioner.
• Be sure to observe the breaker capacity.
WARNING :
• The customer should not install this unit.
If installation is done incorrectly, it may cause a fire, an electric shock, or injury from the unit falling, water leaking,
etc.
• Do not use intermediate connection of the power supply cord or the extension cord and do not connect many
devices to one AC outlet.
A fire or an electric shock may result from poor contact, poor insulation, exceeding the permissible current, etc.
Consult your dealer.
WARNING :
Repairs or relocation should not be done by the customer.
If this is done incorrectly, it may cause a fire, an electric shock, or an injury from the unit falling, water leaking, etc.
