The thermostat cannot be used to set room temperature during the FAN mode
(the temperature will not appear on the remote control unit’s display).

About three seconds later, the entire display will reappear.

Example: When set to 26 °C
The thermostat setting should be considered a standard value, and may differ
somewhat from the actual room temperature.

To Set the Fan Speed

Press the FAN CONTROL button (Fig. 6 M).

Each time the button is pressed, the fan speed changes in the following order:
s AUTO s HIGH s MED s LOW s QUIET

About three seconds later, the entire display will reappear.

When set to AUTO:

Heating : Fan operates so as to optimally circulate warmed air.
However, the fan will operate at very low speed when the temperature
of the air issued from the indoor unit is low.
Cooling : As the room temperature approaches that of the thermostat setting,
the fan speed becomes slower. Example: When set to AUTO
Fan : The fan will operate at the optimum speed in accordance with the
room temperature in the vicinity of the indoor unit.

When set to QUIET:

SUPER QUIET operation begins. The indoor unit’s airflow will be reduced for qui-
eter operation.
● SUPER QUIET operation cannot be used during Dry mode. (The same is true
when dry mode is selected during AUTO mode operation.)
● During Super Quiet operation, Cooling performance will be reduced somewhat.

To Stop Operation

Press the START/STOP button.

OPERATION
About Mode Operation

AUTO:
● Depending on the room temperature at the time operation begins, the operating
mode will be switched automatically as shown in the accompanying table.
Also, depending on the operating mode, the room temperature setting will cause
the “standard” temperature to be set as shown.

Actual Room Operating Mode Thermostat Setting

Temperature (standard setting)
30 °C or above → Cooling → 27 °C
27 to 30 °C → Cooling → 26 °C
24 to 27 °C → Dry → 24 °C
22 to 24 °C → Monitor
Below 22 °C → Heating → 23 °C

The operating mode and standard thermostat settings are selected automatically
when operation begins.
● When automatic operation is initiated, the fan will run at very low speed for about
one minute while the unit detects and selects the proper operating mode.
● Once the operating mode has been set, the mode will not change even if the
room temperature changes.
However, during the monitor operation mode, if the room temperature changes
to below 22 °C, the mode will automatically switch to Heat, and when it rises
above 24 °C the mode will automatically switch to Dry.
● When in the monitor mode, the fan will operate very slowly.
● If the START/STOP button is pressed to recommence operation within two hours
after stopping automatic operation, the unit will begin operating from the same
mode as before.

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 twenty-four 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 auto-
matically stop (OFF timer) after you go to sleep, then start (ON timer) automati-
cally in the morning before you arise.

ADJUSTING THE DIRECTION OF AIR CIRCULATION

Vertical (up-down) direction of airflow is adjusted by pressing the Remote Control Unit’s AIR FLOW DIRECTION button. Hori-
zontal (right-left) airflow direction is adjusted manually, by moving the Air Flow Direction Louvers.
Whenever making horizontal airflow adjustments, start air conditioner operation and be sure that the vertical air direction
louvers are stopped.

● Before cleaning the air conditioner, be sure to turn it off and disconnect the power supply cord.
CAUTION! ● Be sure the intake grille (Fig. 1 9) is installed securely.
● When removing and replacing the air filters, be sure not to touch the heat exchanger, as per-
sonal injury may result.

● If dirt is allowed to accumulate on the air filter, air flow
will be reduced, lowering operating efficiency and increas-
ing noise.
● During periods of normal use, the air filters should be
cleaned every two weeks.

When using the optional Air Cleaning Filter

● Install the optional Air Cleaning Filter set (APS-02F) as instructed (installation instructions are furnished with the Air Clean-
ing Filter set).

● 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.
● When shutting down the unit for one month or more, first allow the fan mode to operate continuously for about one-half
day to allow internal parts to dry thoroughly.

TROUBLESHOOTING
In the event of a malfunction (burning smell, etc.), immediately stop operation, turn off the cir-
WARNING! cuit 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 your circuit breaker to ensure that power is completely off.

Before requesting service, perform the following checks:

Symptom Problem See Page

FUNCTION ately: pressor will not operate for about 3 minutes, in order to prevent
fuse blowouts. —
● Whenever the power supply plug is disconnected and then recon-
nected to a power outlet, 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 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.
● During Heating operation, a sizzling sound may be heard occa-
sional. This sound is produced by the Automatic Defrosting op- 15
eration.
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 ● During Cooling or Dry operation, a thin mist may be seen emitted
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 Automatic 15
Defrosting operation.

Airflow 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 for a higher setting.

● During Heating operation, the unit will temporarily stop opera-

tion (between 7 and 15 minutes) as the Automatic Defrosting mode

● If the air conditioner is used 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 temperature 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), Dehumidifying, and air-circulation of rooms in
