About Mode Operation
AUTO:
● When the room temperature is 2 ° C
higher than the set temperature, the
mode will switch between Cooling and
Drying.
● During the Drying mode operation, the
FAN setting should be switched to LOW
for a gently cooling effect during which
the fan may temporarily stop rotating.
● If the mode automatically selected by the
unit is not satisfactory, see page 6 for instructions on changing the mode setting
(COOL, DRY, FAN).

Cooling:
● Use to cool your room.
Dry:
● Use for gently cooling while dehumidifying your room.
● 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 detecting room humidity.
● Then fan speed cannot be changed manually when Dry mode has been selected.
Fan:
● Use to circulate the air throughout your room.
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:
The heat and cool functions of this unit
cannot operate at the same time.

About the PROGRAM timer
● The PROGRAM timer allows you to integrate OFF timer
and ON timer operations in a single sequence. The sequence can involve one transition from OFF timer to ON
timer, or from ON timer to OFF timer, within a twentyfour hour period.
● The first timer function to operate will be the one set nearest to the current time. The order of operation is indicated by the arrow in the remote control unit’s display
(OFF → ON, or OFF ← ON).
● One example of PROGRAM timer use might be to have
the air conditioner automatically stop (OFF timer) after
About the ON timer
● The timer function is designed to bring your room to a
comfortable temperature by the set time; as a result, the
unit automatically begins operation before the set time
so that the room reaches the desired temperature by the
time set on the timer (“Nice-Morning Timer”).
● The hotter it is in summer, or the colder it is in winter, the
earlier that operation will begin.

To Use the SLEEP timer
While the air conditioner is operating or stopped, press the
SLEEP button.
Both the indoor unit’s OPERATION indicator lamp (red) and the TIMER indicator

About the SLEEP timer
To prevent excessive warming or cooling during sleep, the SLEEP timer function automatically modifies the thermostat setting
in accordance with the time setting. When the set time has elapsed, the air conditioner completely stops.
During Cooling/Dry operation:
When the SLEEP timer is set, the thermostat setting is automatically raised 1 °C every sixty minutes. When the thermostat has been raised a total of 2 °C, the thermostat setting at
that time is maintained until the set time has elapsed, at
which time the air conditioner automatically turns off.

CLEANING AND CARE
CAUTION!
● 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.
Cleaning the Air Filter
1. Push the intake grille pushbuttons (two
places).
2. Open the intake grille.
OPEN
PUSH
3. Hold down the hook at A and pull the filter out.

● When reinstalling the filter, be sure that the hooks at A
and B engage correctly into place.

4. Clean the air filters.
Remove the dust from the air filters by vacuuming or
washing them. After washing, allow the air filters to dry
thoroughly in an area protected from sunlight.
● Dust can be cleaned from the air filter either with a vacuum
cleaner, or by washing the filter in a solution of mild detergent and warm water. If you wash the filter, be sure to
allow it to dry thoroughly in a shady place before reinstalling.
● If dirt is allowed to accumulate on the air filter, air flow
will be reduced, lowering operating efficiency and increasing noise.
● During periods of normal use, the air filters should be
cleaned every two months.

A
Intake grille
● 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.

TROUBLESHOOTING
WARNING!
Before requesting service, perform the following checks:
NORMAL
FUNCTION
Doesn’t operate immediately:
Noise is heard:
Smells:
Mist or steam are
emitted:
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.
Symptom
● 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 power switch 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 operation, a slight squeaking sound may be heard. This is
the result of minute expansion and contraction of the front cover
due to temperature changes.
● 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.
Problem

CHECK ONCE
MORE
Airflow is weak or stops:
Symptom
Doesn’t operate at all:
Poor Cooling performance:
The unit operates differently from the remote control unit’s setting:
● The fan may operate at very low speed during Dry operation or
when the unit is monitoring the room’s temperature.
● In the monitor AUTO operation, the fan will operate at very low
speed.
Items to check
● Has there been a power failure?
● Has a fuse blown out, or a circuit breaker been tripped?
● Is the timer operating?
● Is the air filter dirty?
● Are the air conditioner’s intake grille or outlet port blocked?
● Did you adjust the room temperature settings (thermostat) cor-
rectly?
● Is there a window or door open?
● In the case of Cooling operation, is a window allowing bright sun-
light to enter? (Close the curtains.)
● In the case of Cooling operation, are there heating apparatus and
computers inside the room, or are there too many people in the
room?
● Are the remote control unit’s batteries dead?
● Are the remote control unit’s batteries loaded properly?

OPERATING TIPS
Operation and Performance
Low Ambient Cooling
When the outdoor temperature drops, the outdoor unit’s fans may switch to Low Speed.
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.
● Should a power failure occur during TIMER operation, the
timer will be reset and the unit will begin (or stop) operating under the new timer setting. In this event, the TIMER
indicator lamp (green) will flash (see Page. 4).
● 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 plug, reconnect it, and then
use the remote control unit to resume operation.
Temperature and Humidity Range
Cooling/Dry Mode
Outdoor temperature
Indoor temperature
Indoor humidity
● 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 and Dry modes, 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.
