1. Safety Precautions
Before installing the unit, make sure you read all the
“Safety Precautions”.
The “Safety Precautions” provide very important
points regarding safety. Make sure you follow them.
Please report to or take consent by the supply
authority before connection to the system.
• Do not operate the unit for a long time in high humidity, e.g.
leaving a door or window open. In the cool mode, if the unit is
operated in a room with high humidity (80% RH or more) for a
long time, water condensed in the air conditioner may drop and
wet or damage furniture, etc.
• Do not touch the upper air outlet vane or the lower air outlet
damper during operation. Otherwise, condensation may form and
the unit may stop operating.
Caution:
• Do not use any sharp object to push the buttons, as this may
damage the remote controller.
• Never block or cover the indoor or outdoor unit’s air inlets or
outlets.
• Never wipe the remote controller with benzene, thinner chemical
rags, etc.
• This appliance is intended to be used by expert or trained users
in shops, in light industry and on farms, or for commercial use by
lay persons.
• Children should be supervised to ensure that they do not play
with the air conditioner.
• This appliance is not intended for use by persons (including
children) with reduced physical, sensory or mental capabilities,
or lack of experience and knowledge, unless they have been
given supervision or instruction concerning use of the appliance
by a person responsible for their safety.
• This appliance can be used by children aged from 8 years and
above and persons with reduced physical, sensory or mental
capabilities or lack of experience and knowledge if they have
been given supervision or instruction concerning use of the
appliance in a safe way and understand the hazards involved.
Children shall not play with the appliance. Cleaning and user
maintenance shall not be made by children without supervision.
• When installing or relocating, or servicing the air conditioner, use
only the specified refrigerant (R410A) to charge the refrigerant
lines. Do not mix it with any other refrigerant and do not allow air
to remain in the lines.
If air is mixed with the refrigerant, then it can be the cause of
abnormal high pressure in the refrigerant line, and may result in
an explosion and other hazards. The use of any refrigerant other
than that specified for the system will cause mechanical failure
or system malfunction or unit breakdown. In the worst case, this
could lead to a serious impediment to securing product safety.
Warning:
• These appliances are not accessible to the general public.
• The unit must not be installed by the user. Ask the dealer or an
authorized company to install the unit. If the unit is installed
improperly, water leakage, electric shock or fire may result.
• Do not alter the unit. It may cause fire, electric shock, injury or
water leakage.
• Do not stand on, or place any items on the unit.
• Do not splash water over the unit and do not touch the unit with
wet hands. An electric shock may result.
• Do not spray combustible gas close to the unit. Fire may result.
• Do not place a gas heater or any other open-flame appliance
where it will be exposed to the air discharged from the unit.
Incomplete combustion may result.
• Do not remove the front panel or the fan guard from the outdoor

• Never repair the unit or transfer it to another site by yourself.
• When you notice exceptionally abnormal noise or vibration, stop
operation, turn off the power switch, and contact your dealer.
• Never insert fingers, sticks etc. into the air inlets or outlets.
• If you detect odd smells, stop using the unit, turn off the power
switch and consult your dealer. Otherwise, a breakdown, electric
shock or fire may result.
• This air conditioner is NOT intended for use by children or infirm
persons without supervision.
• If the refrigeration gas blows out or leaks, stop the operation of
the air conditioner, thoroughly ventilate the room, and contact
your dealer.

Notes (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 2 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 confirm that the signal transmitted from the remote controller has
been received. Signals can be received up to approximately 7 meters, 23 feet in a direct line
from the indoor unit in an area 45° to the left and right of the unit. However, illumination such
as fluorescent lights and strong light can affect the ability of the indoor unit to receive signals.
If the operation lamp near the receiver on the indoor unit is blinking, the unit needs to be in-
spected. 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 hu-
midity.
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.
If the indoor unit beeps 4 times when you are using the wireless remote controller, switch the
auto mode setting to the AUTO (single set point) mode or AUTO (dual set point) mode.
For details, refer to the included Notice (A5 sheet) or the Installation Manual.
Battery installation/replacement
1. Remove the top cover, insert two LR6 AA
batteries, and then install the top cover.
2. Press the Reset button.

Note:
Even if you press the ON/OFF button immediately after shutting down the operation is progress, the air conditioner will not start for about 3 minutes.
This is to prevent the internal components from being damaged.
The settable temperature range varies with the model of outdoor units and remote controller.
3. Operation
What the blinking mode icon means
The mode icon will blink when other indoor units in the same refrigerant
system (connected to the same outdoor unit) are already operated in a
different mode. In this case, the rest of the unit in the same group can
only be operated in the same mode.
Press the [F2] button to decrease the preset temperature, and press the
[F3] button to increase.
• Refer to the table on this page for the settable temperature range for
different operation modes.
• Preset temperature range cannot be set for Fan/Ventilation operation.
• Preset temperature will be displayed either in Centigrade in 0.5- or
1-degree, Fahrenheit in 1-2 degree increments, or in Fahrenheit, de-
pending on the indoor unit model and the display mode setting on the
remote controller.
Automatic operation (single set point)
■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 1.5°C, 4°F or more above the set temperature for 3 minutes,
the air conditioner switches to cool mode. In the same way, if the room
temperature remains 1.5°C, 4°F or more below the set temperature for
3 minutes, the air conditioner switches to heat mode.
Cool mode 3 minutes (switches
from heating to cooling)
Set temperature +1.5°C, +4°F
Set temperature
Set temperature -1.5°C, -4°F
3 minutes (switches
from cooling to heating)
■Because the room temperature is automatically adjusted in order to
maintain a fixed effective 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).
3.2. Mode Selection
Each pressing of the [F1] button cycles
through the following operation modes.
Select the desired operation mode.

• Refer to the table on page 7 for the settable temperature range for
different operation modes.
• The preset temperature settings for cooling and heating in the
Auto (dual set point) mode are also used by the Cool/Dry and Heat
modes.
• The preset temperatures for cooling and heating in the Auto (dual
set point) mode must meet the conditions below:
• Preset cooling temperature is higher than preset heating temperature.
• The minimum temperature difference requirement between cooling and
heating preset temperatures (varies with the models of indoor units
connected) is met.
* If preset temperatures are set in a way that does not meet the minimum
temperature difference requirement, both preset temperatures will
automatically be changed within the allowable setting ranges.

ordinary air quality. Depending on the air quality, the filter may require
more frequent cleaning.
The cumulative time at which filter needs cleaning depends on the model.
• This indication is not available for wireless remote controller.
Caution:
• Ask authorized people to clean the filter.
►Cleaning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
completely before putting them back into the unit.
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, 122 °F), 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.
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.

7. Troubleshooting
Having trouble? Here is the solution. (Unit is operating normally.)
Air conditioner does not heat or cool well. ■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 inlet or outlet blocked?
■Has a door or window been left open?
When heating operation starts, warm air does not blow from the indoor
unit soon.
■Warm air does not blow until the indoor unit has sufficiently warmed
up.
During heat mode, the air conditioner stops before the set room
temperature is reached.
■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 defrosting operation. Normal operation should begin after
approximately 10 minutes.
Airflow up/down direction changes during operation or airflow up/down
direction cannot be set.
■During cool mode, the vanes automatically move to the step 1 position
after 1 hour when the vane is set to “Step 2” to “Step 5”. This is to
prevent water from forming and dripping from the vanes.
■During heat mode, the vanes automatically move to the step 1
position when the airflow temperature is low or during defrosting
mode.
When the airflow up/down direction is changed, the vanes always move
up and down past the set position before finally stopping at the position.
■When the airflow up/down direction is changed, the vanes move to the
set position after detecting the base position.
A flowing water sound or occasional hissing sound is heard. ■These sounds can be heard when refrigerant is flowing in the air
conditioner or when the refrigerant flow is changing.
A cracking or creaking sound is heard. ■These sounds can be heard when parts rub against each due to
expansion and contraction from temperature changes.
The room has an unpleasant odor. ■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.
A white mist or vapor is emitted from the indoor unit. ■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.
Water or vapor is emitted from the outdoor unit. ■During cool mode, water may form and drip from the cool pipes and
joints.
■During heat 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.
The air conditioner does not operate even though the ON/OFF button
is pressed. The operation mode display on the remote controller
disappears.
■Is the power switch of the indoor unit turned off? Turn on the power
switch.
“ ” appears 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.
When restarting the air conditioner soon after stopping it, it does not
operate even though the ON/OFF button is pressed.
■Wait approximately 3 minutes.
(Operation has stopped to protect the air conditioner.)
Air conditioner operates without the ON/OFF button being pressed. ■Is the on timer set?
Press the ON/OFF button to stop operation.
■Is the air conditioner connected to a central remote controller?
Consult the concerned people who control the air conditioner.
■Does “ ” appear in the remote controller display?
Consult the concerned people who control the air conditioner.
■Has the auto recovery feature from power failures been set?
Press the ON/OFF button to stop operation.
Air conditioner stops without the ON/OFF button being pressed. ■Is the off timer set?
Press the ON/OFF button to restart operation.
■Is the air conditioner connected to a central remote controller?
Consult the concerned people who control the air conditioner.
■Does “ ” appear in the remote controller display?
Consult the concerned people who control the air conditioner.
Remote controller timer operation cannot be set. ■Are timer settings invalid?
If the timer can be set, or appears in the remote controller
display.
“PLEASE WAIT” appears in the remote controller display. ■The initial settings are being performed. Wait approximately 3
minutes.
An error code appears in the remote controller display. ■The protection devices have operated to protect the air conditioner.
■Do not attempt to repair this equipment by yourself.
Turn off the power switch immediately and consult your dealer. Be
sure to provide the dealer with the model name and information that
appeared in the remote controller display.
Draining water or motor rotation sound is heard. ■When cooling operation stops, the drain pump operates and then
stops. Wait approximately 3 minutes.

7. Troubleshooting
Having trouble? Here is the solution. (Unit is operating normally.)
Noise is louder than specifications. ■The indoor operation sound level is affected by the acoustics of the
particular room as shown in the following table and will be higher than
the noise specification, which was measured in an echo-free room.

Noise levels 3 to 7 dB 6 to 10 dB 9 to 13 dB
Nothing appears in the wireless remote controller display, the display
is faint, or signals are not received by the indoor unit unless the
remote controller is close.
■The batteries are low.
Replace the batteries and press the Reset button.
■If nothing appears even after the batteries are replaced, make sure that
the batteries are installed in the correct directions (+, –).
After battery installation/replacement of remote controller, part of
function cannot be used.
■Please check that the clock setting is completed. If clock setting is not
done, please complete.
The operation lamp near the receiver for the wireless remote
controller on the indoor unit is blinking. ■The self diagnosis function has operated to protect the air conditioner.
■Do not attempt to repair this equipment by yourself.
Turn off the power switch immediately and consult your dealer. Be sure
to provide the dealer with the model name.
Warm air blows from the indoor unit intermittently when heating mode
is off or during fan mode. ■When another indoor unit is operating in heating mode, the control valve
opens and closes occasionally to maintain stability in the air conditioning
system. This operation will stop after a while.
* If this will cause an undesirable rise in the room temperature in small
rooms, etc., stop the operation of the indoor unit temporarily.
The wireless remote controller does not operate (the indoor unit
beeps 4 times). ■Switch the auto mode setting to the AUTO (single set point) mode or
AUTO (dual set point) mode. For details, refer to the included Notice (A5
sheet) or the Installation Manual.
Refrigerant noise is heard or warm air comes out from the suspended
indoor unit.
■A small amount of refrigerant flows into the suspended indoor unit while
other indoor units are in operation at HEAT mode.
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.
