	IMPORTANT SAFETY INSTRUCTIONS
WARNINGS FOR USE
1	Do not pull or deform the power supply cord. Pulling and misuse of the power supply cord
	can result in damage to the unit and cause electrical shock.
2	Be careful not to expose your body directly to the outlet air for a long time. It may affect
	your physical conditions.
3	When using the air conditioner for infants, children, elderly, bedridden, or disabled people
	make sure the room temperature is suitable for those in the room.
4	Never insert objects into the unit. Inserting objects can result in injury due to the high
	speed rotation of internal fans.
5	Ground the air conditioner without fail. Do not connect the grounding wire to gas pipe,
	water pipe, lightning rod or telephone grounding wire. Incomplete grounding may cause
	electric shock.
6	If anything is abnormal with the air conditioner (ex. a burning smell), stop the operation
	immediately and turn the circuit breaker OFF.
7	The appliance shall be installed in accordance with national wiring regulations. Improper
	cable connection can cause the power supply cord, plug and the electrical outlet to
	overheat and cause fire.
8	If the supply cord is damaged, it must be replaced by the manufacturer or its service agent
	or a similarly qualified person in order to avoid a hazard. Use only the manufacture-
	specified power cord for replacement.

WARNINGS FOR INSTALLATION / REMOVAL / REPAIR

• Do not attempt to install/remove/repair the unit by yourself. Incorrect work will cause electric shock, water leak, fire etc. Consult your dealer or other qualified service personnel for the installation/removal/repair of the unit.

This equipment complies with the requirements of Directives 89/336/EEC and 73/23/ EEC as amended by 93/68/EEC.

ENGLISH

E-1

Open a window or door periodically to ventilate the room, especially when using gas appliances. Insufficient ventilation may cause oxygen shortage.

IMPORTANT SAFETY INSTRUCTIONS

CAUTIONS FOR USE

1

2	Do not operate the buttons with wet hand. It may cause electric shock.
3	For safety, turn the circuit breaker off when not using the unit for an extended period of
	time.
4	Check the outdoor unit mounting rack periodically for wear and to make sure it is firmly
	in place.
5	Do not put anything on the outdoor unit nor step on it. The object or the person may fall
	down or drop, causing injury.
6	This unit is designed for residential use. Do not use for other applications such as in a
	kennel or greenhouse to raise animals or grow plants.
7	Do not place a vessel with water on the unit. If water penetrates into the unit, electrical
	insulations may deteriorate and cause electric shock.
8	Do not block the air inlets nor outlets of the unit. It may cause insufficient performance
	or troubles.
9	Be sure to stop the operation and turn the circuit breaker off before performing any
	maintenance or cleaning. A fan is rotating inside the unit and you may get injured.

10 Do not splash or pour water directly on the unit. Water can cause electrical shock or equipment damage.

11 This appliance is not intended for use by young children or infirm persons without supervision.

Young children should be supervised to ensure that they do not play with the appliance.

CAUTIONS FOR LOCATION / INSTALLATION

• Make sure to connect the air conditioner to power supply of the rated voltage and frequency.

Use of a power supply with improper voltage and frequency can result in equipment damage and possible fire.

•Do not install the unit in a place where inflammable gas may leak. It may cause fire. Install the unit in a place with minimal dust, fumes and moisture in the air.

•Arrange the drain hose to ensure smooth drainage. Insufficient drainage may cause wetting of the room, furniture etc.

•Make sure a leak breaker or a circuit breaker is installed, depending on the installation location, to avoid electrical shock.

•The built-in protective device may prevent the unit from operating when used out of this range.

•Condensation may form on the air outlet if the unit operates continuously in the COOL or DRY mode when humidity is over 80 percent.

WHEN POWER FAILURE OCCURS

This air conditioner has a memory function to store settings when a power failure occurs.

After power recovery, the unit will automatically re-start in the same settings which were active before the power failure, except for timer settings.

If the timers were set before a power failure, they will need to be re-set after power recovery.

PREHEATING FUNCTION

In the HEAT operation, the indoor fan may not start for two to five minutes after the unit is turned on to prevent cold air from blowing out of the unit.

DE-ICING FUNCTION

•When ice forms on the heat exchanger in the outdoor unit during the HEAT operation, an automatic de-icer provides heat for about 5 to 10 minutes to remove the ice. During de-icing, the inside and outside fans stop operating.

•After de-icing is completed, the unit automatically resumes operation in the HEAT mode.

HEATING EFFICIENCY

•The unit employs a heat pump that draws heat from the outside air and releases it into the room. The outside air temperature therefore greatly affects the heating efficiency.

•If the heating efficiency is reduced due to low outside temperatures, use an additional heater.

•It takes time to warm up and heat the entire room because of the forced air circulation system.

TIPS ON SAVING ENERGY

Below are some simple ways to save energy when you use your air conditioner.

SET THE CORRECT TEMPERATURE

•Setting the thermostat 1°C higher than the desired temperature in the COOL mode and 2°C lower in the HEAT mode will save approximately 10 percent in power consumption.

•Setting the temperature lower than necessary during cooling operation will result in increased power consumption.

BLOCK DIRECT SUNLIGHT AND PREVENT DRAFTS

•Blocking direct sunlight during cooling operation will reduce power consumption.

•Close the windows and doors during cooling and heating operations.

SET PROPER AIR FLOW DIRECTION TO OBTAIN THE BEST AIR CIRCULATION

KEEP FILTER CLEAN TO ENSURE THE MOST EFFICIENT OPERATION MAKE MOST OF THE TIMER OFF FUNCTION

DISCONNECT THE POWER CORD WHEN THE UNIT IS NOT USED FOR AN EXTENDED PERIOD OF TIME

• The indoor unit still consumes a small amount of power when it is not operating.
