●Connect securely, without looseness.

●In the case of direct line connections, turn on the breaker.

MASTER CONTROL Switch

POSITION FUNCTION

)(OFF) The air conditioner is switched off.

FAN Fan only is operating to provide filtered air without

cooling effect.

SUPER QUIET Fan speed is low and cooling efficiency is intermediate

with low noise level.

NORMAL A cooling effect is obtained by a quieter operation than

“HIGH POWER”.

HIGH POWER Fan speed is at its maximum resulting in maximum

cooling effect.

Cooling

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

To maintain a comfortable room temperature an important factor is the circulation

of air. Room air can be circulated without cooling by selecting FAN position on

the master control.

Air circulation only without cooling effect may also be achieved with the thermostat

knob turned counterclockwise to “1” position and with the master control knob

at either “cool” position.

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.

MASTER CONTROL

9385175112_En.p65 7/20/04, 4:14 PM8

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.
