SAFETY PRECAUTIONS

Before using the appliance, read these “PRECAUTIONS” thoroughly and operate in the correct way.

The instructions in this section all relate to safety; be sure to maintain safe operating conditions.

“DANGER, “WARNING” and “CAUTION” have the following meanings in these instructions:

DANGER!

This mark indicates procedures which, if improperly performed, are most likely to

result in the death or serious injury to the user or service personnel.

 

 

 

WARNING!

This mark indicates procedures which, if improperly performed, might lead to the

death or serious injury of the user or service personnel.

 

CAUTION!

This mark indicates procedures which, if improperly performed, might possibly result

 

in personal harm to the user, or damage to property.

Do not attempt to install this air conditioner by yourself.

DANGER!

This air conditioner contains no user-serviceable parts. Always consult authorized

 

 

service personnel for repairs.

When moving, consult authorized service personnel for disconnection and installation of the air conditioner.

Do not become excessively chilled by staying for many hours in the direct cooling airflow.

Do not insert fingers or objects into the outlet port or intake grille.

Do not start and stop air conditioner operation by disconnecting the power supply cord.

Take care not to damage the power supply cord.

In the event of a malfunction (burning smell, etc.), immediately stop operation, turn off the breaker, and consult authorized service personnel.

In the event of refrigerant leakage, be sure to keep away from fire or any flammables. (consult an authorized service personnel)

If the power supply cord of this appliance is damaged, it should only be replaced by the authorized service personal, since special purpose tools and specified cord are required.

Provide occasional ventilation during use.

CAUTION! Do not direct airflow at fireplaces or heating apparatus.

Do not climb on, or place objects on, the air conditioner.

Do not hang objects from the indoor unit.

Do not set flower vases or water containers on top of air conditioners.

Do not expose the air conditioner directly to water.

Do not operate the air conditioner with wet hands.

Do not pull power supply cord.

Turn off power supply when not using the indoor unit for extended periods.

Check the condition of the installation stand for damage.

Do not place animals or plants in the direct path of the airflow.

Do not drink the water drained from the air conditioner.

Do not use in applications involving the storage of foods, plants or animals, precision equipment, or art works.

Connection valves become hot during Heating; handle with care.

Do not apply any heavy pressure to radiator fins.

Operate only with air filters installed.

Do not block or cover the intake grille and outlet port.

En-1

Ensure that any electronic equipment is at least 3.3 ft (1m) away from either the indoor or outdoor units.

CAUTION!

Avoid installing the air conditioner near a fireplace or other heating apparatus.

 

 

 

 

When installing the indoor and outdoor unit, take precautions to prevent access to infants.

 

 

Do not use inflammable gases near the air conditioner.

 

 

This appliance is not intended for use by persons (including children) with reduced physical,

 

 

sensory or mental capabilities, or lack of experience and knowledge, unless they have been

 

 

given supervision or instruction concerning use of the appliance by a person responsible for

 

 

their safety. Children should be supervised to ensure that they do not play with the appliance.

FEATURES AND FUNCTIONS

INVERTER

At the start of operation, large amount of power is used to bring the room quickly to the desired temperature. Afterwards, the unit automatically switches to a low power setting for economic and comfortable operation.

WIRELESS REMOTE CONTROLLER

The Wireless Remote Controller allows convenient control of air conditioner operation.

ECONOMY OPERATION

When ECONOMY operation mode is operated, the room temperature will be little higher than the set-temp under cooling mode and lower than set-temp under heating mode. Therefore, the ECONOMY mode is able to save more energy than other normal mode.

AUTO CHANGEOVER

The operation mode (cooling, dry, heating) is switched automatically to maintain the set temperature, and the temperature is kept constant at all times.

MINIMUM HEAT OPERATION

The room temperature can be maintained at 50°F so as to prevent the room temperature from falling too far.

PROGRAM TIMER

The program timer allows you to integrate OFF timer and ON timer operations in a single sequence. The sequence can involve 1 transition from OFF timer to ON timer, or from ON timer to OFF timer, within a 24 hour period.

SLEEP TIMER

When the SLEEP button is pressed during Heating mode, the air conditioner’s thermostat setting is gradually lowered during the period of operation; during cooling mode, the thermostat setting is gradually raised during the period of operation. When the set time is reached, the unit automatically turns off.

OMNI-DIRECTIONAL AIRFLOW (SWING OPERATION)

3-dimensional control over air direction swing is possible through dual use of both an UP/DOWN air direction swing and RIGHT/LEFT air direction swing. Since UP/DOWN air direction fl aps operate automatically according to the operating mode of the unit, it is possible to set air direction based on the operating mode.

REMOVABLE INTAKE GRILLE

The indoor unit’s INTAKE GRILLE can be removed for easy cleaning and maintenance.

MILDEW-RESISTANT FILTER

The AIR FILTER has been treated to resist mildew growth, thus allowing cleaner use and easier care.

SUPER QUIET OPERATION

When the FAN button is used to select QUIET, the unit begins super-quiet operation; the indoor unit’s airflow is reduced to produce quieter operation.

POLYPHENOL CATECHIN AIR CLEANING FILTER

The polyphenol catechin air cleaning fi lter uses static electricity to clean fi ne particles and dust in the air such as tobacco smoke and plant pollen that are too small to see.

The fi lter contains catechin, which is highly effective against various bacteria by suppressing the growth of the bacteria adsorbed to the fi lter.

Note that when the air cleaning fi lter is installed, the amount of air produced decreases, causing a slight decrease in the indoor unit’s performance.

NEGATIVE AIR IONS DEODORIZING FILTER

It comprises pottery super micro particles which can produce negative air ions having the effect of deodorizing and can absorb and remit the peculiar smell at home.

HORIZONTAL AIRFLOW: COOLING/ DOWNWARD AIRFLOW: HEATING

For cooling, use horizontal airflow so the cool air does not blow directly on the occupants in the room. For heating, use downward airfl ow to send powerful, warm air to the fl oor and create a comfortable environment.
