CAUTION

lDuring maintenance, be sure to place the removed components in a safe place to avoid damage to them.

lDo not touch the aluminum ﬁ ns of heat exchanger built-in the indoor or outdoor unit to avoid personal injury when you install or maintain the unit.

Also, pay attention not to be scratched or pinched your hand by inner parts.

lNever use water hotter than 40 °C. The unit body may warp or change color.

lDo not use inﬂ ammable 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.

lBefore cleaning the unit, be sure to turn it off and all the power supply has been disconnected.

Cleaning the Air Filter

If dirt is allowed to collect in the air ﬁ lter, the airﬂ ow will be reduced, leading to reduced performance, and increased operating noise. Be sure to clean the

ﬁ lters at the beginning of the operating season, and about every 2 weeks during periods of frequent operation.

The air ﬁ lter is attached to the front panel, and you need to remove the intake grille ﬁ rst, when you get access to the air ﬁ lter.

Cleaning the unit

Clean the unit by wiping with a cloth moisten with cool or warm water, then wipe with another soft, clean, and dry cloth.

When not using the unit for extended periods (1 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.

When not using the unit for extended periods, turn off the electrical breaker or disconnect the power plug for safety.

Check the power cord

lRemove the built-up dirt and dust on the power plug and the electrical outlet periodically.

lCheck the power cord occasionally to conﬁ rm that it is not damaged by cuts or abrasions. If you discover damage to the cord, consult authorized service

personnel.

Operation

Unit Overview

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

An adequate ﬂ ow 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 ﬁ ltered

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 ﬁ n coil may freeze up due to excessively low room temperature caused by low outdoor

temperature at night.

Once the ﬁ n coil becomes frozen, the airﬂ ow 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 sufﬁ ciently low. This condition may occur when the

thermostat switches off automatically because cooled air, when it passes through the vertical airﬂ ow louvers positioned downwards and the horizontal

airﬂ ow 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 ﬂ ow 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 Direction Control

When the SUPER WAVE switch is turned to “ON” position, the horizontal airﬂ ow 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.

In the event of a malfunction (burning smell, etc.), immediately

stop operation, turn off the electrical breaker or disconnect the

power plug, and consult authorized service personnel.

In the place where bears be sufﬁ cient 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 ﬂ oor. 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 ﬁ lls up

the gap between the rails on the inner bottom of the cabinet and

bottom side of the base.

Before requesting service, perform the following checks:

Symptom Problem

NORMAL

FUNCTIONS

Noise is heard: During operation and immediately after stopping the unit, the sound of water ﬂ owing 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 ﬂ owing).

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.

Smells: 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.

CHECK ONCE

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 ﬁ lter 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?

If the problem persists after performing these checks, immediately stop operation, turn off the electrical breaker or disconnect the power plug, and consult

authorized service personnel.
