Cooling
To obtain maximum cooling effect in the hot summer, select
position HIGH POWER (BLUE) on the MASTER CONTROL.
Maximum moisture removal, air circulation and dust removal
are effected at the same time.
Selection of SUPER QUIET (BLUE) reduces operating noise.
Heating
To obtain maximum heating effect in severe winter select
position HIGH POWER (RED) on the MASTER CONTROL.
Maximum air circulation is obtained at the same time.
Selection of SUPER QUIET (RED) reduces heating effect and
operating noise. However you may feel a higher tempera-
ture at the air outlet compared to the HIGH POWER (RED)
position, due to the reduced fan speed.
NOTE:
After you start driving, it will take approximately 10
minutes for the air from this unit become warm.
This delay is normal.
If you find that insufficient room heat is produced, we
recommend that you use the air conditioner together with
other heating appliances.
Air Circulation
To maintain a comfortable room temperature, an important
factor is the circulation of air. Room air can be circulated
without cooling/heating by selecting either HIGH FAN or LOW
FAN position on the MASTER CONTROL.
Circulation of air without cooling/heating can be also effected
as follows:
1. When operating with the MASTER CONTROL switched
to HIGH POWER (RED) or SUPER QUIET (RED), turn the
thermostat fully clockwise.
2. When operating with the MASTER CONTROL switched
to HIGH POWER (BLUE) or SUPER QUIET (BLUE), turn
the thermostat fully counterclockwise.
Thermostat Control
Once the thermostat is set to the desired temperature, the
room temperature will be automatically adjusted without
excessive or insufficient cooling/heating and thus a com-
fortable environment is always maintained.
When cooling, turn the THERMOSTAT knob clockwise to
increase cooling effect.
When heating, turn the THERMOSTAT knob counterclock-
wise to increase heating effect.
The thermostat controls the compressor only, and accordingly
the fan is constantly circulating air even during the period when
the compressor is off during cooling/heating operation. To stop
the cooling/heating operation set the master control OFF
position.
1. When you wish to lower the temperature, turn the THER-
MOSTAT knob clockwise in the direction of the higher
numbers on the dial.
2. When you wish to increase the temperature, turn the
THERMOSTAT knob counterclockwise in the direction of
the lower numbers.
3. When the THERMOSTAT is set at positions “5”, “6” or
“7”, comfortable room temperatures can usually be
obtained. Please note that it is unhealthy for the room
temperature to be lower than approximately 22˚C.
4. When the THERMOSTAT is positioned at “10”, the room-
side fin coil may freeze up due to excessively low room
temperature (for example, below 18˚C) caused by low
outdoor temperature at night.
FGE_9353031037 1/9/04, 11:02 AM4

- 5 -
Once the fin coil becomes frozen, the air flow from the air
conditioner is restricted by the frost, and the room tem-
perature may rise due to the resultant weak cooling per-
formance of the air conditioner.
5. The THERMOSTAT positions “8”, “9” and “10“ can be
used when the room temperature does not become suffi-
ciently low. This condition may occur when the thermo-
stat switches off automatically because cooled air, when
it passes through the horizontal louvers positioned down-
wards and the vertical louvers positioned to the left, makes
a short circuit and the recirculated air touches the sensor
of the thermostat.
NOTE: The thermostat controls the compressor only and
accordingly the fan is constantly circulating air even
during the period when the compressor is off.
Important
When cooling/heating is stopped by means of either the
MASTER CONTROL or THERMOSTAT do not restart cooling/
heating for at least three (3) minutes. If cooling/heating is
restarted within this time, the compressor motor will be
subjected to an over current and a compressor motor safety
device will be actuated. If this occurs, restarting cooling/
heating will not be possible for about 20 minutes.
Automatic Defrosting
When continuous heating is effected for a long period of
time with low outside temperatures, the condenser tends to
frost up and heating efficiency will drop. To prevent this
condition, the unit is equipped with an automatic defrosting
system.
When frosting occurs the fan is stopped automatically. After
5 or so minutes the frost will have melted and the normal
heating function is then automatically returned.
Exhaust Air Control
By setting EXHAUST AIR control lever to the appropriate
positions between “OPEN” and “CLOSE” positions, it is
possible to expel the room air to the desired extent. The
quantity of air to be expelled will increase when the lever is
positioned closer to the “OPEN” position.
NOTE: Cooling/heating effect will be reduced when operating
EXHAUST open.
Air Direction Control
When the SUPER WAVE switch is turned to “ON” position,
the vertical louver is automatically actuated and sweeps the
jet of air alternately, right and left and thus more effective
cooling/heating will be obtained.
Louvers may be stopped at any position when SUPER WAVE
switch is turned off.
Sweep angle and direction can be adjusted with the select
lever. The sweep can span an area either to the right or to
the left. Select a sweep angle suitable to the layout of the
room and the position of the air conditioner in the room
which the air conditioner is installed.

Air Flow Adjustment
With this air conditioner, three air directions can be obtained
as shown in the figures below. When the air flow direction
is set, adjust to the desired sweep angle.
NOTE: Setting the vertical louver at high room humidity.
1. Set the SUPER WAVE switch to ON.
2. Or, to use with the SUPER WAVE switch to OFF,
set the switch to OFF when the vertical louver
moves to the center.
Adjusting Sweep Angle
When the select lever is moved to the right or left, the sweep
angle increases or decreases. Adjust the sweep angle within
SUPER WAVE ZONE range.
NOTE: When the select lever is returned to the “NEUTRAL”,
the vertical louvers do not normal operate. If the
select lever is returned to the “NEUTRAL” in error,
readjust the sweep angle referring to “Adjusting Air
Flow Direction and Sweep Angle”.

MAINTENANCE
Room Air Filter
A filter is provided on the rear of the removable panel. Since
the function of this filter is to filter dust and dirt in the air,
please clean it regularly before it becomes clogged with dust.
Wash the filter with clean water. If it is very dirty, rinse it in a
synthetic detergent before washing in clean water. Allow
the filter to dry thoroughly in the shade after washing.
Remove the filter in the following manner.
Using the frip position, push the bottom of the removable panel
up with your hand, pull it toward you, and the removable panel
will be easily removed (See Fig. 1, Fig. 2).
The filter is attached to the rear side of the removable panel.
Pull the lower edge of the filter forward in order to remove
the filter from the removable panel (See Fig. 3). To replace
the filter, insert the top edge of the filter under the hooks at
the top of the removable panel, then press into the two lower
hooks to fix into place (See Fig. 4).
When you want to refit the removable panel, insert it by
pushing the upper edge of the removable panel against the
upper part of the front panel. How to Remove the Front Panel
Remove the front panel in the following manner.
The front panel is attached to the cabinet with snap clips at
the top and screws at the bottom. Remove the removable
panel first and you will see two screws at the left and right
of the bottom side. Take them off. (See Fig. 5) Hold up the
front panel with your hands to remove it completely. (See
Fig. 6) When refitting the front panel, insert the two clips on
the upper part of the panel into the two slots at the top side
of the cabinet. Press the front panel at its bottom side and
fix it with screws. This completes refitting of the front panel.

NOTE:
1. A fuse may blow when a particularly large demand for
electricity, which exceeds the capacity of the fuse, occurs
in your home or when the voltage of the main power line
drops due to some fault. If the fuse blows again after
replacement with a new one, please call your dealer or
service company.
2. Your air conditioner also acts to dehumidify the room air
and to expel the water produced, therefore drops of wa-
ter emitting from the outside of the unit is quite normal.
3. Please note, your room air conditioner will automatically
control the room temperature within the thermostat range
... 16˚C (cooling) and 32˚C (heating - reverse cycle type).
4. The noise level of your air conditioner may be felt to be
higher at night than during the day. This is quite normal.
This results from the fact that environmental noise level
is lower at night so the noise level of the air conditioner
is felt to be relatively higher.
5. When defrosting under heating operation, the curious
sound which may be heard is quite normal.
Front panel Things to Do Before Calling a Serviceman
1. If your air conditioner does not operate, check the following
items before calling for service.
a) Check that the power plug is properly connected to
the power socket.
b) Check your fuses.
2. When cooling or heating effect is not obtained even with
the air conditioner operating, make the following checks.
a) Check that the thermostat setting is higher than the
room temperature when cooling.
b) Check that the thermostat setting is lower than the
room temperature when heating.
c) Check the filter. A clogged filter will reduce cooling
efficiency. When filter is excessively dirty, cooling coils
may ice up.
d) If the cooling coils are iced up, wash the filter. To get
rid of the ice quickly, operate the air conditioner with
the MASTER CONTROL knob on “FAN”position until
all the ice has gone.
General Information
1. When the ambient temperature drops to 21˚C (70˚F) or
less, icing-up may occur on the inside cooling coils, and
is quite normal (when cooling).
2. The compressor motor does not require lubrication as it
contains sufficient oil.
3. No lubrication is required for the bearings of the fan mo-
tor as dust shielded ball bearings containing grease are
fitted.
