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.

Programming timer operation
The ON timer and the OFF timer can be used in combination. The timer of the set time that is reached first will operate first.
(“ ” mark indicates the order of timer operations.)
• If the current time has not been set, the timer operation cannot be used.
NOTE:
If the main power is turned off or a power failure occurs while AUTO START/STOP timer is active, the timer setting is
cancelled. As these models are equipped with an auto restart function, the air conditioner starts operating with timer
cancelled at the same time that power is restored.
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.

BEFORE CONTACTING THE SERVICE REPRE-
SENTATIVE, CHECK THE FOLLOWING AGAIN
Question
The air conditioner cannot
be operated for about 3 min-
utes when restarted.
Cracking sound is heard.
The air from the indoor unit
smells strange.
The fan stops during the
DRY operation.
The sound of water flowing
is heard.
The sound as burbling is
heard.
The room cannot be cooled
sufficiently.
Mist is discharged from the
air outlet of the indoor unit.
Answer (not a malfunction)
• This protects the air conditioner according to in-
structions from the microprocessor. Please wait.
• This sound is generated by the expansion/con-
traction of the front panel, etc. due to change in
temperature.
• The air conditioner may suck in an odor adher-
ing to the wall, carpet, furniture, cloth, etc. and
blow it out with the air.
• In DRY operation, the unit operates using the
same refrigerant circuit as in COOL operation.
DRY operation time has to be reduced in order
to lower humidity without much room tempera-
ture decreasing. So the compressor sometimes
stops, and at the same time the indoor fan stops.
This prevents water condensed on the heat ex-
changer from evaporating again.
• This is the sound of refrigerant flowing inside the
air conditioner.
• This is the sound of condensed water flowing in
the heat exchanger.
• This is the sound of the heat exchanger defrost-
ing.
• This sound is heard when the outside air is ab-
sorbed from the drain hose in turning on the
range hood or the ventilation fan and that makes
water flowing in the drain hose spout out.
This sound is also heard when the outside air
blows into the drain hose in case the outside wind
is strong.
• When a ventilation fan or a gas cooker is used
in a room, the cooling load increases, resulting
in an insufficient cooling effect.
• When the outside air temperature is high, the
cooling effect may not be sufficient.
• The cool air from the air conditioner rapidly cools
moisture in the air inside the room, and it turns
into mist.
WHEN YOU THINK THAT TROUBLE HAS OCCURRED
Question
The air conditioner cannot
be operated.
The room cannot be cooled
or heated sufficiently.
The air from the indoor unit
smells strange.
The display on the remote
controller does not appear
or it is dim. The indoor unit
does not respond to the re-
mote control signal.
When a power failure oc-
curs.
Check points or Remedy
• Is the breaker turned on?
• Is the fuse blown?
• Is the ON timer set? (Page 8)
• Is the temperature setting correct? (Page 7)
• Is the filter clean? (Page 9)
• Are there any obstacles blocking the air inlet or
outlet of the indoor or outdoor unit?
• Is a window or door open?
• Is the filter clean? (Page 9)
• Are the batteries exhausted? (Page 5)
• Is the polarity (+, -) of the batteries correct?
(Page 5)
• Are any buttons on the remote controller of other
electric appliances being pressed?
• Does the air conditioner start operating again?
If the air conditioner had operated before the
power failure, as these models are equipped with
an auto restart function, the air conditioner
should start operating again. (Refer to Descrip-
tion of “AUTO RESTART FUNCTION” on page
6.)
Question
The air flow direction
changes during operation.
The direction of the hori-
zontal vane cannot be ad-
justed with the remote con-
troller.
Water leaks from the out-
door unit.
White smoke is discharged
from the outdoor unit.
Air does not blow out soon
in the heating operation.
The operation is stopped
for about 10 minutes in the
heating operation.
Hissing sound is some-
times heard.
The room cannot be heated
sufficiently.
In a multi-unit system, the
indoor unit which is not op-
erating becomes warm and
a sound, similar to water
flowing, is heard from the
unit.
The air conditioner starts
the operation only with the
main power turned on,
though you do not operate
the unit with the remote
controller.
Answer (not a malfunction)
• When the air conditioner is operated in COOL
or DRY mode, if the operation continues with air
blowing down for 1 hour, the direction of the air
flow is automatically set to horizontal to prevent
condensed water from dropping.
• In the heating operation, if the air flow tempera-
ture is too low or when defrosting is being done,
the horizontal vane position is automatically set
to horizontal.
• During COOL and DRY operations, pipe or pipe
connecting sections are cooled and this causes
water to condense.
• In the heating operation, the defrosting opera-
tion makes water frozen on the outdoor unit melt
and drip down.
• In the heating operation, water condensed on
the heat exchanger drips down.
• In the heating operation, vapor generated by the
defrosting operation looks like white smoke.
• Please wait as the air conditioner is preparing
to blow out warm air.
• Defrosting of the outdoor unit is being done (De-
frosting operation).
Since this is completed in 10 minutes, please
wait. (When the external temperature is too low
and humidity is too high, frost is formed.)
• This is the sound when the flow of refrigerant
inside the air conditioner is switched.
• When the outside air temperature is low, the
heating effect may not be sufficient.
• A small amount of refrigerant continues to flow
into the indoor unit even though it is not operat-
ing.
• These models are equipped with an auto restart
function. When the main power is turned off with-
out stopping the air conditioner with the remote
controller and is turned on again, the air condi-
tioner will start operation automatically in the
same mode as the one set with the remote con-
troller just before the shutoff of the main power.
Even if the above items are checked, when the air conditioner does not
recover from the trouble, stop using the air conditioner and consult your
dealer.
In the following cases, stop using the air conditioner and consult your dealer.
•
When water leaks from the indoor unit.
•
When the left operation indicator lamp blinks.
•
When the breaker trips frequently.
•
The remote control signal may not be received in a room where an electronic
ON/OFF type fluorescent lamp (inverter-type fluorescent lamp, etc.) is used.
•
Operation of the air conditioner may interfere with radio or TV reception in
areas where the reception is weak. An amplifier may be required for the af-
fected device.
•
When thunder is heard, stop operation and disconnect the power supply plug
or turn off the breaker. Otherwise, the electrical parts may be damaged.

INSTALLATION, RELOCATION AND INSPECTION
Installation place
Avoid installing the air conditioner in the following places.
•
Where flammable gas could leak.
CAUTION:
Do not install the unit where flammable gas could leak.
If gas leaks and collects around the unit, it may cause
an explosion.
•
Where there is much machine oil.
•
Salty places such as the seaside.
•
Where sulfide gas is generated such as a hot spring.
•
Where oil is splashed or where the area is filled with
oily smoke.
•
Where there is high-frequency or wireless equipment.
CAUTION:
• Earth the unit.
Do not connect the earth to a gas pipe, water pipe, lightning rod or the earth of a telephone. If the earthing is
incorrect, it may cause an electric shock.
• Install an earth leakage breaker depending on the place where the air conditioner is to be installed (humid places,
etc.).
If the earth leakage breaker is not installed, it may cause an electric shock.
Inspection and maintenance
•
When the air conditioner is used for several seasons, the capacity may be lowered due to dirt inside the unit.
•
Depending on the condition, an odor may be generated or dehumidified water may not drain out smoothly due to dirt,
dust, etc.
•
It is recommended that the unit be inspected and maintained (charged) by specialist in addition to normal maintenance.
Consult your dealer.
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
•
When the air conditioner is to be removed or re-installed because of rebuilding, moving, etc., special techniques and work
are required.
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.
Consult your dealer.
Disposal
To dispose of this product, consult your dealer.
If you have any questions, consult your dealer.
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.
Electrical work
•
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.
