Unit Overview
Fan (High speed) and compressor
operate at rapid cooling.
This lever is used to adjust the air flow
direction and sweep angle.
Room air is drawn outside.
Exhaust vent is closed.
To obtain maximum cooling effect in the hot summer select position HIGH POWER on the master control. Maximum moisture removal, air circulation and
dust removal are effected at the same time.
Selection of SUPER QUIET reduces operating noise.
Air Circulation
An adequate flow of air is very important for comfort. When the master control knob is set at “FAN” position, the fan only is actuated so that the air is filtered
and circulated without cooling effect.
Air circulation only without cooling effect may also be achieved with the thermostat knob turned counterclockwise to “1” position and with the master control
at either “HIGH POWER” or “SUPER QUIET” position.
Thermostat Control
The thermostat is set by means of the thermostat control. When the room temperature is higher than the thermostat setting, the compressor is
automatically switched on to provide a cooling effect. When the room temperature is lower than the thermostat setting, the compressor is automatically
switched off to stop cooling.
It can be seen therefore, that the thermostat serves to keep the room temperature constant by causing the compressor to start and stop automatically.
1. When you wish to lower the temperature, turn the thermostat control clockwise in the direction of the higher numbers on the dial.
2. When you wish to increase the temperature, turn the thermostat control 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. Note that it is unhealthy for the room
temperature to be lower than approximately 22 °C.
4. When the thermostat control 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.
Once the fin coil becomes frozen, the airflow from the air conditioner is restricted by the frost, and the room temperature may rise due to the resultant
weak cooling performance of the air conditioner.
5. 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 switches off automatically because cooled air, when it passes through the vertical airflow louvers positioned downwards and the horizontal
airflow 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 restarting the cooling operation after it has been turned off by either master control of thermostat, be sure to allow at least 3 minutes.
If cooling operation is restarted immediately after it is turned off, an over current will flow through the compressor motor and the safety
device will be actuated. If the safety device is actuated it will not be possible to restart the compressor motor for about 20 minutes.
Air Flow Adjustment
Right side
With this air conditioner, three air directions can be obtained as shown in the figures on the left side.
When the air flow direction is set, adjust to the desired sweep angle.
Left side
Adjusting Air Flow Direction and Sweep Angle
When the SUPER WAVE switch is turned to “ON” position, the horizontal airflow louvers is automatically actuated and sweeps the jet of air alternately, left
and right and thus more effective cooling will be obtained.
The 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.

Care and Maintenance
Move the select lever fully left to the “NEUTRAL”.
Position the vertical louver to either the left end, center, or the right end .
Move the select lever fully to the right end of the SUPER WAVE ZONE.
Set the SUPER WAVE switch to “ON”.
The sweep angle can be adjusted within the SUPER WAVE ZONE range. When the select lever is
returned to the left, the sweep angle decreases. Adjust sweep angle according to preference.
Note: If the select lever is returned to the “NEUTRAL” in error, the vertical louvres do not function properly.
In this event, carry out the procedure from the beginning.”

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 2 weeks during periods of frequent operation.
The air filter is attached to the front panel, and you need to remove the intake grille first, when you get access to the air filter.

may be affected. For this reason, regular professional maintenance is recommended. Consult authorized service personnel.
Unit: mm
Typical installation
Air filter removal
Push the bottom of the intake grille up
with your hand, and pull it toward you.
● When constructing a timber frame, arrange so that the outside rear of the air
conditioner is between 5 and 10 mm lower than the front of the unit.
This allows condensed water to drain off outside the room.
If the inside of the air conditioner is lower, condensed water and rain may flow
into the room.
Avoid installing the air conditioner near a fireplace or other heating
In the place where bears be sufficient to the weight of the air
conditioner concerning installation, noise and vibration choose
such place without increasing.
● For installation, avoid any places in direct sunlight. Combined
installation with a sunshade is recommended; installing the unit
under direct sunlight may cause low cooling performance or
increasing of the electricity consumption.
● Consult the installation in a special place to a selling agent.
Because sea breeze sometimes becomes to a cause of
malfunction by corrosion etc., in the case that the place become
use with machine oil, the place of many place etc., that occur,
sulfuration gas such as a hot spring area that hits in a seashore
area it buys and give consultation to that selling agent.
● Avoid the neighbourhood that be discharged dust, a lampblack,
steam, such as an exhaust port, a ventilation fan.
● It is place where do not give neighbours trouble about removal
water or a wind and noise.
● Where practicable, locate the air conditioner with the lower edge
of the cabinet approximately 0.75 m (29.5”) to 1.5 m (59”) from
the floor. This usually gives the optimum air circulation pattern
within the room for cooling and heating.
● When installing the attached insulation (620 mm x 40 mm, t12),
insert it from the inside of the room so that the insulation fills up
the gap between the rails on the inner bottom of the cabinet and
bottom side of the base.
Power Supply
Before requesting service, perform the following checks:
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.
● Some smell may be emitted from the 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 unit. This results from the sudden
cooling of room air by the air emitted from the air conditioner, resulting in condensation and misting.
Does not operate at all:
● Is the power plug disconnected from its outlet?
● Has there been a power failure?
● Has a fuse blown out, or a circuit breaker been tripped?
Poor cooling performance:
Is the air filter dirty?
Are the air conditioner’s intake grille or outlet port blocked?
Did you adjust the room temperature settings (thermostat) correctly?
Is there a window or door open?
In the case of cooling operation, is a window allowing bright sunlight to enter? (Close the curtains.)
In the case of cooling operation, are there heating apparatus or computers inside the room, or are
there too many people in the room?
