INFORMATION

CAPABILITIES

Heating Capability

• This room air conditioner utilizes a heat pump system that absorbs

exterior heat and brings it into a room to be heated. As the ambient

temperature gets lower, heating capability will also lower. In such a

situation, the inverter work to increase compressor rpm to keep the

unit’s heating capability from decreasing. If the unit’s heating perfor-

mance is still unsatisfactory, other heating appliances should be used

to augment this unit’s performance.

• The air conditioner is designed to heat an entire room so that it may take some time before you feel warm.

Timer operation is recommended for effective preheating ahead of the desired time.

Cooling and Dehumidifying Capabilities

• If the heat present in a room exceeds the unit’s cooling capacity (for example, if there are many people in

the room or other heating appliances are used), the preset room temperature may not be reached.

CAUTION

Do not use a stove

or any other

hightemperature

devices in proximity

to the indoor unit.

• When fan speed, room temperature are set with the remote controller before starting manual operation and

the buttons are released, the indication of settings will go off in 10 seconds and only the operation mode

will be displayed.

• Pressing the button while the unit is in operation will let the protective circuit work so that the unit will

not operate for approximately 3 minutes.

• During heating operation, the indoor unit’s color indicator lamp may flash with no air emitted for a while.

• If you feel cold wind during heating operation with the (HI) fan speed or want to make the unit operation

quieter after the room is heated, use of (AUTO) setting is recommended.

• With the (LOW) setting, the unit’s cooling capability will lower slightly.

• With the (LOW) setting, the unit’s heating capacity will vary with the operating conditions.

VARIOUS FUNCTIONS

• When the timer has been programmed, the unit will not operate even if the set time is reached unless the

unit receives a signal from the remote controller. Confirm that timer programming is complete (beep) and

the TIMER lamp of the indoor unit lights.

• If the (SLEEP) button is pressed while the ON/OFF timer is programmed, the sleep timer takes priority.

• During sleep timer operation, the fan speed sets to (LOW) regardless of the preset speed. The remote

controller display indication will remain unchanged even with the (LOW) setting.

REGULAR INSPECTION

PLEASE CHECK THE FOLLOWING POINTS EVERY EITHER HALF YEARLY OR YEARLY. CONTACT

YOUR SALES AGENT SHOULD YOU NEED ANY HELP.

WARNING

Check to see if the unit’s earth line has been con-

nected correctly.

If the earth line is disconnected or faulty, unit failure or

electric shock hazard may result.

Check to see if the mounting frame has rusted ex-

cessively or if the outdoor unit has tilted or become

unstable.

It could collapse or fall, causing injury.

AFTER SALES SERVICE AND WARRANTY

WHEN ASKING FOR SERVICE, CHECK THE FOLLOWING POINTS.

CONDITION CHECK THE FOLLOWING POINTS

• Do the batteries need replacement?

• Is the polarity of the inserted batteries correct?

• Is the fuse all right?

• Is the voltage extremely high or low?

• Is the circuit breaker “ON”?

• Is the power plug inserted?

• Do you have any power cut?

• Is the air filter blocked with dust?

• Is the set temperature suitable?

• Have horizontal air deflectors been adjusted to their correct

positions according to the operation mode selected?

• Are the air inlets or air outlets of indoor and outdoor units

blocked?

• Is the fan speed “LOW”?

When it does not operate.

When it does not cool well.

When it does not heat well.

If the remote controller is not

transmitting a signal.

(Remote controller display is

dim or blank.)

■ The following phenomena do not indicate unit failure.

The unit is preparing to blow warm air. Please wait.

The outdoor unit is defrosting. Please wait.

Refrigerant flow noise in the pipe or valve sound generated when flow rate is

adjusted.

Noise generated when the unit expands or contracts due to temperature changes.

Noise generated with the indoor unit fan’s rpm changing such as operation start

times.

Noise of the motorized valve when the unit is switched on.

During heating, the operation

indicator blinks and air blow stops

Hissing or fizzy sounds

Squeaking noise

Rustling noise

WARNING

Clicking noise

Check to see if the power plug is securely inserted

• If the unit still fails to operate

normally after performing the

above inspections, turn the

circuit breaker off, or pull the

power plug out, and contact

your sales agent immediately.

Contact your sales agent immediately if the

following phenomena should occur:

•

The circuit breaker switches off or the fuse blows

frequently.

•

The switch operation is not stable.

•

Foreign matter or water accidentally enters the unit interior.

•

The power cord gets excessively hot or its insulation is torn or stripped.

•

TIMER lamp on the indoor unit display blinks.

As the nature of the failure can be identified by the blinking cycle,

check the blinking cycle before turning off the circuit breaker.

(

)

Notes

• In quiet operation or stopping the running, the following phenomena may

occasionally occur, but they are not abnormal for the operation.

(1) Slight flowing noise of refrigerant in the refrigerating cycle.

(2) Slight rubbing noise from the fan casing which is cooled and then

gradually warmed as operation stops.

• The odor will possibly be emitted from the room air conditioner because

the various odor, emitted by smoke, foodstuffs, cosmetics and so on,

sticks to it. So please clean the air filter and the evaporator regularly to

reduce the odor.

Noise of the ventilation fan sucking in air present in the drain hose and blowing out

dehumidifying water that had accumulated in the condensed water collector. For

details, consult your sales agent.

Operation noise changes due to power variations according to room temperature

changes.

Mist is generated as the air within the room is suddenly cooled by conditioned air.

Water generated during defrosting operation evaporates and steam is emitted.

Caused as the smells and particles of smoke, food, cosmetics, etc. present in room

air become attached the unit and blown off into the room again.

Defrosting is underway (as the heating operation is stopped, the microcomputer

checks frost accumulated in the outdoor unit and instructs the unit to perform

automatic defrosting if necessary).

Shows preheating or defrosting operation is underway.

As the protective circuit or preheat sensor operates when unit operation is stopped

during preheating and then restarted, or when operation mode is switched from cooling

to heating, the lamp continues to blink.

Actual room temperature may deviate slightly from the remote controller's

temperature setting depending on the number of people in the room, indoor or

outdoor conditions.

• Please contact your sales agent immediately if the air conditioner still fails to operate normally after

the above inspections. Inform your agent of the model of your unit, production number, date of

installation. Please also inform him regarding the fault.

Please note:

On switching on the equipment, particularly when the room light is dimmed, a slight brightness

fluctuation may occur. This is of no consequence.

The conditions of the local Power Supply Companies are to be observed.
