About Mode Operation
*Heating
● Always set the temperature higher than the current room temperature. If it is set lower than the current room temperature, heating
will not start.
● For about 3 to 5 minutes after starting heating, the fan will operate very slowly, then switch to the selected fan setting. This period
allows the indoor unit’s heat- exchanger to perform before emitting warm air.
● During defrosting (see page 9), the heating mode will be temporarily interrupted. The defrost indicator will turn on the remote controller
display.
Cooling
● Always set the temperature lower than the current room temperature. If it is set higher than the current room temperature, the unit
will not enter the cooling mode and only the fan will operate.
Fan
● The room temperature cannot be adjusted in the FAN mode. (The room temperature is not displayed on the remote controller.)

● Before cleaning the unit, be sure to stop the unit and disconnect the power supply.
● Turn off the electrical breaker.
● A fan operates at high speed inside the unit, and personal injury could result.
CARE AND MAINTENANCE
Installing the Air Filter
Be sure the fi lter is always installed in the inlet air grille of the indoor unit.
Filters can be purchased through your local dealer.
Cleaning the Air Filter
If dirt is allowed to collect in the air fi lter, the airfl ow will be reduced, leading to reduced performance, and increased operation noise.
Be sure to clean the fi lters regularly.
How to Cleaning
Use a vacuum cleaner to remove dust and dirt from the air fi lter, or wash in a synthetic detergent. After washing, dry in a shaded
place, then reinstall.
CAUTION!
● When used for extended periods, the unit may accumulate dirt inside, reducing its performance. We recommend that the unit
be inspected regularly, in addition to your own cleaning and care. For more information, consult authorized service personnel.
● When cleaning the unit’s body, do not use water hotter than 40 °C, harsh abrasive cleansers, or volatile agents like benzene or
thinner.
● Do not expose the unit body to liquid insecticides or hairsprays.
● If the unit will not be operated for a period of one month or more, be sure to allow the inner parts of the unit to dry thoroughly, in
advance, by operating the unit in fan mode for half a day.
SYSTEM OPERATION
<Control Several Units with just one Remote Controller>
One remote controller can control up to 16 air conditioners.
All the air conditioners can be operated with the same setting.
When using, consult authorized service personnel.

Instructions relating to heating (*) are applicable only to “HEAT & COOL MODEL” (Reverse Cycle).
* Microcomputer-controlled Automatic
Defrosting
When the outside temperature is low and the humidity high, frost
will collect on the outside unit, reducing heater effi ciency. When
this happens, the computer will automatically start the defrost
cycle. During the defrost cycle, the indoor fan will shutdown and
the defrost indicator of the remote controller will turn on. It will
take anywhere from 4 to 15 minutes before the air conditioner
starts up again.
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 intermit-
tently.
* Heating Performance
● This air conditioner uses a heat pump which absorbs heat
from outside air and brings it indoors. As a result, its heating
performance is reduced as the temperature of outside air
drops. If you fi nd that insuffi cient room heat is produced, we
recommend that you use the air conditioner together with
other heating appliances.
● Heat-pump type air conditioners use warm-air recirculation to
warm your entire room. As a result, some time will be required
after starting operation until your entire room becomes warm.
* When Indoor and Outdoor Tempera-
tures 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.
OPERATING DETAILS
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.
Operation and Performance
AUTO Restart
Group Control
Temperature and Humidity Range
● 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 turn off the circuit breaker
turn it on again and then use the remote controller to resume
operation.
One remote controller can control up to 16 air conditioners.
All of the air conditioners will be operated with the same settings.
● If the air conditioner is operated under higher temperature conditions than those listed, the built-in protection circuit may operate to
prevent internal circuit damage. Also, during Cooling mode, if the unit is used under conditions of lower temperatures than those
listed above, the heat-exchanger may freeze, leading to water leakage and other damage.
● Do not use this unit for any purposes other than the Cooling, (*) Heating, and air-circulation of rooms in ordinary dwellings.
Permissible range of temperature and humidity are as follows:
Cooling Mode *Heating Mode
Outdoor temperature
COOLING MODEL About 0 to 52 °C —
HEAT & COOL MODEL
(Reverse Cycle)
About 0 to 46 °C About –10 to 21 °C
Indoor temperature
About 0 to 30 °C About below 30 °C
Indoor humidity About 80 % or less
If the unit is used for long
periods under high-humidity
conditions, condensation
may form on the surface
of the indoor unit, and drip
onto the fl oor or other objects
underneath.

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:
Symptom Problem
See Page
NORMAL
FUNCTION
Doesn’t operate
immediately:
● 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.
—
Noise is heard:
● 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 fl owing).
—
*
● During Heating operation, a sizzling sound may be heard oc-
casionally. This sound is produced by the Automatic Defrosting
operation.
9
Smells:
● 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.
—
Mist or steam are
emitted:
● During Cooling 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.
9
Airfl ow is weak or stops:
*
● 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 2 and 16 minutes) as the Automatic
Defrosting mode operates. During the Automatic Defrosting
operation, the defrost indicator of the remote controller will turn on.
9
● The fan may stop when the unit is monitoring the room’s temperature.
—
Water is produced from
the outdoor unit:
*
● During Heating operation, water may be produced from the outdoor unit
due to the Automatic Defrosting operation.
