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.
Power Supply
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
temperature at the air outlet compared to the HIGH
POWER (RED) position, due to the reduced fan speed.
Connect the Power Supply Plug to an electrical point.
●Connect securely, without looseness.
●In the case of direct line connections, turn on the breaker.
MASTER CONTROL Switch
NOTE: After you start driving, it will take approximately
10 minutes for the air from this unit become
warm. This delay is normal.

THERMOSTAT Control Switch
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 comfortable environment is always maintained.
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.
1. When you wish to lower the temperature, turn theTHERMOSTAT Control switch
clockwise in the direction of the higher numbers of the dial.
2. When you wish to increase the temperature, turn theTHERMOSTAT Control switch
counterclockwise in the direction of the lower numbers.
NOTE:
•When the THERMOSTAT Control switch 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.
•When the THERMOSTAT Control switch is set at positioned at “10”, the
room-side fin coil may freeze up and prevent effective cooling. If this happens,
turn the switch to “FAN”, and turn the THERMOSTAT Control switch
counterclockwise.
CAUTION!
When cooling/heating is stopped by means of either the MASTER CONTROL
or THERMOSTAT Control switch do not restart cooling/heating for at least 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.

AIR DIRECTION ADJUSMENT
WARNING!
●Do not put fingers or other objects into the air louvres; an internal fan operates at high
speed and could result in personal injury or damage.
●Do not operate the air conditioner with the airflow louvres blocked, since malfunction
could result.
Super Wave
When the SUPER WAVE switch is put on, the SUPER WAVE moves and blows air
to the left and right (See Fig. 1). On attaining the desirable direction of the air
blow and on putting off the SUPER WAVE switch, the air blow in that particular
direction can be achieved. Do not move the SUPER WAVE's louvers inside the
outlet with the hand as it might cause damage.
The SUPER WAVE's louvers do not move even if the SUPER WAVE switch is in
the MASTER CONTROL )(OFF) position
For horizontal air direction control, rotate the horizontal louvers upward, or down-
ward (See Fig. 2).
NOTE:
The THERMOSTAT positions “8”, “9”and “10”can be used when the room
temperature does not become sufficiently low. This condition may occur
when the THERMOSTAT Control switches off automatically because cooled
air, when it passes through the Up-Down Airflow-direction Louvres positioned
downwards, makes a short circuit and the recirculated air touches the sensor
of the THERMOSTAT.

CAUTION!
Before cleaning the unit, be sure to stop the unit and disconnect the power supply.
1. Disconnect the power plug. 2. Turn off the electrical breaker.
●A fan operates at high speed inside the unit, and personal injury could result.
Cleaning the Air Filter
If dirt is allowed to collect in the air filter, the airflow will
be reduced, leading to reduced performance, and increased
operating noise. Be sure to clean the filters at the beginning
of the operating season, and about every two weeks during
periods of frequent operation.
Remove the Air Filter
Remove the Air Filter from the front panel assembly by lift
up the air filter's handle and pull out.
Cleaning
Use a vacuum cleaner to remove dust and dirt from the
air filter, or wash in a synthetic detergent. After washing,
dry in a shaded place, then reinstall.
Installing the Air Filter
Insert the filter to the panel, making sure the two upper tabs
and the lower tab are return properly to their holes in the
panel.
Cleaning the Indoor Unit
Clean the indoor unit by wiping with a cloth dipped in
cool or warm water, then wipe with another soft, clean,
dry cloth.
CAUTION!
Never use water that is hotter than 40°C. The body
may warp or change colour.
Do not use inflammable sprays such as lacquer or
hair spray near the air conditioner.
The unit can be damaged by gasoline, benzine, thinners,
insecticides and other chemical agents.
When Not Using the Unit for Extended
Periods (One Month or More)
Operate the unit on fan mode for about one-half day on a
day with clear weather, to assure that the internal parts
are dry.
CAUTION!
When not using the unit for extended periods, discon-
nect the power plug for safety.
●When a plug is left connected, dust may collect on
the blades, leading to smoke and fire hazard.
Check the Power Cord
Check the power cord occasionally to confirm that it is
not damaged by cuts or abrasions. If you discover damage
to the cord, consult authorized service personnel.
More than 40 °C
Inspections and Repairs
Depending on the conditions of use, the internal parts of an air conditioner will become dirty after about two or three
seasons of use, and performance may be affected. For this reason, regular professional maintenance is recommended.
Consult authorized service personnel.

TROUBLESHOOTING
In the event of a malfunction (burning smell, etc.), immediately stop operation, disconnect
the power plug, 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 disconnect the power plug or turn off your circuit breaker
to ensure that power is completely off.
WARNING!
Before requesting service, perform the following checks:
Symptom
Noise is heard:
Smells:
Mist or steam are emitted:
Airflow is stop:
Problem
●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 mode, a sizzling sound may be heard occasional. This sound
is produced by the automatic defrosting operation. (Heating)
●Some smell may be emitted from the air conditioner. This smell is the re-
sult of room smells (furniture, tobacco, etc.) which have been taken into
the air conditioner.
●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 fan may stop, and steam may be seen rising
from the unit. This is due to operation of the defrosting mode. (Heating)
●During Heating mode, the unit will temporarily stop operation (between 6
and 12 minutes) as the automatic defrosting mode operates. During
defrosting operation, the OPERATION indicator lamp will flash slowly.

OPERATION DETAILS
Please read and understand the following details regarding this air conditioner.
Operation and Performance
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 find that insufficient 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 recircula-
tion to warm your entire room. As a result, some time
will be required after starting operation until your entire
room becomes warm.
Microcomputer-controlled Automatic
Defrosting
When outside air temperatures are low and humidity is high,
using the Heating mode may result in the creation of frost
inside the outdoor unit, lowering its heating performance.
A built-in microcomputer is used to monitor this condition
and when necessary, the defrosting mode operates, result-
ing in a temporary interruption of the Heating mode (both
indoor and outside fans will stop). About 7 to 15 minutes
will be required for normal operation to be resumed.
Temperature and Humidity Range
Permissible ranges of temperature and humidity are as
follows:
Outdoor temperature:
About 21°C to 43°C
Indoor temperature:
About 21°C to 32°C
Indoor humidity:
About 80% or less. If the unit is used for
long periods under conditions of high
humidity, water may condense on and drip
from the surface of the unit.
Outdoor temperature:
About 0°C to 21°C
Indoor temperature:
About 30°C or less
If the unit is used under higher temperature conditions
than those noted here, the automatic protection circuit may
operate, interrupting the operation. If the unit is used under
lower temperature conditions than those noted here, the heat
exchanger may freeze, causing water leakage or other
malfunction.
●Do not use the air conditioner for any purpose other
than room cooling or room heating.
