FEATURES AND FUNCTIONS
■ Energy saving and Comfortable function
■ Clean function
INVERTER
REMOVABLE AIR FILTER
At the start of operation, large amount of power is used to bring the
room quickly to the desired temperature. Afterwards, the unit automatically switches to a low power setting for economic and comfortable operation.
The indoor unit’s air filter can be removed for easy cleaning
and maintenance.
ECONOMY OPERATION
When ECONOMY operation mode is operated, the room temperature will be little higher than the set-temp under cooling mode
and lower than set-temp under heating mode. Therefore, the
ECONOMY mode is able to save more energy than other normal
mode.
SUPER QUIET OPERATION
When the FAN button is used to select QUIET, the indoor
unit begins super quiet operation; the indoor unit’s airflow
is reduced to produce quieter operation.
AUTO CHANGEOVER
The operation mode (cooling, dry, heating) is switched automatically to
maintain the set temperature, and the temperature is kept constant at all
times.
■ Convenient function
■ Remote controller
WIRED REMOTE CONTROLLER
The wired remote controller allows convenient control of
indoor unit operation.
WIRELESS REMOTE CONTROLLER (OPTION)
The optional wireless remote controller can be used.When you
use remote controller, there are following different points as
compared with using wired remote controller.
[ The additional function for wireless ones ]
• SLEEP timer
• TIMER
• 10°C HEAT operation
And you can use both wireless and wired remote controller simultaneously. (But function is limited.)
[ The restricted functions for wired ones ]
• Weekly timer
• Temperature set back timer
WEEKLY TIMER
Use this timer function to set operating times for each day
of the week. Use the DAY OFF setting to switch off timed
operation for a selected day in the coming week. Because
all days can be set together, the weekly timer can be used
to repeat the timer settings for all of the days.
TEMPERATURE SET BACK TIMER
Use this timer function to change the set temperature in
the operation times set for each day of the week. This can
be used together with other timer settings.

TROUBLESHOOTING
Instructions relating to heating (*) are applicable only to “HEAT & COOL MODEL” (Reverse Cycle).
In the event of a malfunction (burning smell, etc.), immediately stop operation, turn off the electrical
breaker, and consult authorized service personnel.
Merely turning off the unit’s power switch will not completely disconnect the unit from the power
source. Always be sure to turn off the electrical breaker to ensure that power is completely off.
Before requesting service, perform the following checks:
WARNING
Symptom
NORMAL
FUNCTION
Does not operate immediately:
Noise is heard:
Problem
If the unit is stopped and then immediately started again, the compressor will not operate for about 3 minutes, in order to prevent
fuse blowouts.
● Whenever the electrical breaker is turned off then on again, the
protection circuit will operate for about 3 minutes, preventing unit
operation during that period.
—
During operation and immediately after stopping the unit, the sound
of water flowing in the air conditioner’s piping may be heard. Also,
noise may be particularly noticeable for about 2 to 3 minutes after
starting operation (sound of coolant flowing).
—
●
●
*● During heating operation, a sizzling sound may be heard
occasionally. This sound is produced by the automatic defrosting
operation.
Smells:
Mist or steam are emitted:
Airflow is weak or stops:
Water is produced from the
outdoor unit:
See Page

●
Some smell may be emitted from the indoor unit. This smell is the
result of room smells (furniture, tobacco, etc.) which have been
taken into the air conditioner.
—
●
During cooling or dry operation, a thin mist may be seen emitted
from the indoor unit. This results from the sudden cooling of room air
by the air emitted from the air conditioner, resulting in condensation
and misting.
—
*● During heating operation, the outdoor unit’s fan may stop, and
steam may be seen rising from the unit. This is due to the automatic
defrosting operation.
13
*● When heating operation is started, fan speed is temporarily very low,
to allow internal parts to warm up.
*● During heating operation, if the room temperature rises above the
thermostat setting, the outdoor unit will stop, and the indoor unit will
operate at very low fan speed. If you wish to warm the room further,
set the thermostat to a higher setting.
—
*● During heating operation, the unit will temporarily stop operation
(between 4 and 15 minutes) as the automatic defrosting mode operates. During the automatic defrosting operation,
will be shown
on the remote controller display.
13
●
The fan may operate at very low speed during dry operation or when
the unit is monitoring the room’s temperature.
—
●
During QUIET operation, the fan will operate at very low speed.

OPERATING TIPS
Instructions relating to heating (*) are applicable only to “HEAT & COOL MODEL” (Reverse Cycle).
Heating Performance*
●
●
This air conditioner operates on the heat-pump principle,
absorbing heat from outdoor air and transferring that heat
indoors. As a result, the operating performance is reduced
as outdoor air temperature drops. If you feel that insufficient
heating performance is being produced, we recommend you
use this air conditioner in conjunction with another type of
heating appliance.
Heat-pump air conditioners heat your entire room by recirculating air throughout the room, with the result that some time
may be required after first starting the air conditioner until the
room is heated.
When Indoor and Outdoor Temperature
are High*
When both indoor and outdoor temperatures are high during use
of the heating mode, the outdoor unit’s fan may stop at times.
Low Ambient Cooling
When the outdoor temperature drops, the outdoor unit’s fans may
switch to Low Speed, or one of the fans may stop intermittently.
Microcomputer-controlled Automatic
Defrosting*
●
When using the heating mode under conditions of low outdoor
temperature and high humidity, frost may form on the outdoor
unit, resulting in reduced operating performance.
In order to prevent this kind of reduced performance, this
unit is equipped with a microcomputer-controlled automatic
defrosting function. During the defrost cycle, the indoor fan will
shutdown and
will be displayed on the remote controller. It will take anywhere from 4 to 15 minutes before the air
conditioner starts up again.
●
After heating operation stops, if frost forms on the outdoor
unit, the unit will start Automatic Defrosting operation.
At this time, the outdoor unit will automatically stop after
operating for a few minutes.
Dual Remote Controllers (optional)
An additional remote controller can be added up to the
maximum of 2 remote controllers. Either remote controller
can control the air conditioner. However, the timer functions
cannot be used at the secondary unit.
Group Control
1 remote controller can control up to 16 air conditioners. All of
the air conditioners will be operated with the same settings.
Group control cannot be used when using it by the
multi type.

When the indoor unit has adjusted your room’s temperature to near the temperature setting, it will begin monitor operation. In the monitor operation mode, the fan will operate at low speed. If the room temperature subsequently changes,
the indoor unit will once again select the appropriate operation (cooling) to adjust the temperature to the value set in the
temperature setting.
●
If the mode automatically selected by the unit is not what you wish, select one of the mode operation (COOL, DRY, FAN).
AUTO [in HEAT & COOL (Reverse Cycle) model]:
●
When AUTO (automatic changeover) is selected, the air conditioner selects the appropriate operation mode (cooling or
heating) according to your room’s present temperature.
●
When AUTO (automatic changeover) operation first selected, the fan will operate at low speed for about a few minute,
during which time the indoor unit detects the room conditions and selects the proper operation mode.

Heating
●
When the air conditioner has adjusted your room’s temperature to near the thermostat setting, it will begin monitor operation. In the monitor operation mode, the fan will operate at low speed. If the room temperature subsequently changes,
the air conditioner will once again select the appropriate operation (heating, cooling) to adjust the temperature to the
value set in the thermostat.
●
If the mode automatically selected by the unit is not what you wish, select one of the mode operation (HEAT, COOL, DRY, FAN).
HEAT *: ● Use to warm your room.
● When heating mode is selected, the air conditioner will operate at very
low fan speed for about 3 to 5 minutes, after which it will switch to the
selected fan setting. This period of time is provided to allow the indoor
unit to warm up before beginning full operation.
● When the room temperature is very low, frost may form on the outside
unit, and its performance may be reduced. In order to remove such frost,
the unit will automatically enter the defrost cycle from time to time. During
automatic defrosting operation, the heat operation will be interrupted.
● After the start of heating operation, it takes sometime before the room
gets warmer.
COOL: ● Use to cool your room.
● Use for gently cooling while dehumidifying your room.
DRY:
● You cannot heat the room during dry mode.
● During dry mode, the unit will operate at low speed; in order to adjust
room humidity, the indoor unit’s fan may stop from time to time. Also, the
fan may operate at very low speed when adjusting room humidity.
● The fan speed cannot be changed manually when dry mode has been
selected.
● Use to circulate the air throughout your room.
FAN:
During heating mode:
Set the thermostat to a temperature setting
that is higher than the current room temperature. The heating mode will not operate if the thermostat is set lower than the
actual room temperature.
During cooling/dry mode:
Set the thermostat to a temperature setting that is lower than the current room
temperature. The cooling and dry modes
will not operate if the thermostat is set
higher than the actual room temperature
(in cooling mode, the fan alone will operate).
During fan mode:
You can not use the unit to heat and cool
your room.

OPERATING TIPS
Instructions relating to inverter (❖) are applicable only to “INVERTER MODEL”.
AUTO Restart
In Event of Power Interruption
●
Should the power supply to the air conditioner be interrupted
by a power failure, the air conditioner will restart automatically
in the previously selected mode once the power is restored.
●
Use of other electrical appliances (electric shaver, etc.) or
nearby use of a wireless radio transmitter may cause the air
conditioner to malfunction. In this event, temporarily disconnect the power supply, reconnect it, and then use the remote
controller to resume operation.
Notices
*● During use of the heating mode, the outdoor unit will occasionally commence the defrost operation for brief periods.
During the defrosting operation, if the user sets the indoor
unit for heating again, the defrosting mode will continue, and
the heating operation will begin after completion of defrosting, with the result that some time may be required before
warm air is emitted.
*● During use of the heating mode, the top of the indoor unit
may become warm, but this is due to the fact that coolant is
circulated through the indoor unit even when it is stopped;
it is not a malfunction.
SELF-DIAGNOSIS
When “Er” in temperature indicator is displayed, inspection of the air conditioning system is necessary. Please consult
authorized service personnel.
