TIPS FOR SAVING ENERGY

TIPS FOR SAVING ENERGY

Here are some tips that will help you minimize the power consumption when you use the air conditioner. You can use your air conditioner more efficiently by referring to the instructions below:

• Do not cool excessively indoors. This may be harmful for your health and may consume more electricity.

• Block sunlight with blinds or curtains while you are operating the air conditioner.

• Keep doors or windows closed tightly while you are operating the air conditioner.

• Adjust the direction of the air flow vertically or horizontally to circulate indoor air.

• Speed up the fan to cool or warm indoor air quickly, in a short period of time.

• Open windows regularly for ventilation as the indoor air quality may deteriorate if the air conditioner is used for many hours.

• Clean the air filter once every 2 weeks. Dust and impurities collected in the air filter may block the air flow or weaken the cooling / dehumidifying functions.

IMPORTANT SAFETY INSTRUCTIONS

CAUTION

Installation

• Always check for gas (refrigerant) leakage after installation or repair of product. Low refrigerant lev-

els may cause failure of product.

• Install the drain hose to ensure that water is drained away properly. A bad connection may cause

water leakage.

• Keep level even when installing the product. To avoid vibration or water leakage.

• Do not install the product where the noise or hot air from the outdoor unit could damage the neigh-

borhoods. It may cause a problem for your neighbors.

• Use two or more people to lift and transport the product. Avoid personal injury.

• Do not install the product where it will be exposed to sea wind (salt spray) directly. It may cause cor-

rosion on the product. Corrosion, particularly on the condenser and evaporator fins, could cause product malfunction or inefficient operation.

• Do not expose the skin directly to cool air for long periods of time. (Don't sit in the draft.) This could

harm to your health.

• Do not use the product for special purposes, such as preserving foods, works of art, etc. It is a con-

sumer air conditioner, not a precision refrigeration system. There is risk of damage or loss of property.

• Do not block the inlet or outlet of air flow. It may cause product failure.

• Use a soft cloth to clean. Do not use harsh detergents, solvents, etc. There is risk of fire, electric

shock, or damage to the plastic parts of the product.

BEFORE USE

Preparing for operation

• Contact an installation specialist for installation.

• Use a dedicated circuit.

Usage

• Being exposed to direct airflow for an extended period of time could be hazardous to your health. Do not expose occupants, pets, or plants to direct airflow for extended periods of time.

• Due to the possibility of oxygen deficiency, ventilate the room when used together with stoves or other heating devices.

• Do not use this air conditioner for non-specified special purposes (e.g. preserving precision devices, food, pets, plants, and art objects). Such usage could damage the items.

Cleaning and maintenance

• Do not touch the metal parts of the unit when removing the filter. Injuries can occur when handling sharp metal edges.

• Do not use water to clean inside the air conditioner. Exposure to water can destroy the insulation, leading to possible electric shock.

• When cleaning the unit, first make sure that the power and breaker are turned off. The fan rotates at a very high speed during operation. There is a possibility of injury if the unit’s power is accidentally triggered on while cleaning inner parts of the unit.

MAINTENANCE AND SERVICE

ENGLISH

Indoor Unit

- Turn the system off before cleanining, To clean, wipe with a soft, dry cloth. Do not use bleach or abrasives.

NOTE

Supply power must be disconnected before cleaning the indoor unit.

Air Filters

The air filters behind the front grille should be checked and cleaned once every 2 weeks or more often if neccessary.

- Never use any of the followings: Water hotter than 40°C.

Could cause deformation and/or discoloration.

Volatile substances. Could damage the surfaces of the air conditioner.

- Remove the Air filters.

Take hold of the tab and pull slightly forward to remove the filter.

CAUTION

When the air filter is to be removed, do not touch the metal parts of the indoor unit. It may cause an injury.

- Clean dirt from the air filter using a vacuum

cleaner or washing with water. If dirt is conspicuous, wash with a neutral

detergent in lukewarm water. If hot water (40°C or more) is used, it may

be deformed.

- After washing with water, dry well in the

shade. Do not expose the air filter to direct sunlight

or heat from a fire when drying it.

- Install the air filter.

MAINTENANCE AND SERVICE

Do not overcool the room.

Keep blinds or curtains closed.

Keep the room temperature uniform.

Make sure that the doors and windows are shut tight.

Clean the air filter regularly.

Ventilate the room occasionally.

ENGLISH

Operation Tips!

This is not good for the health and wastes electricity.

Avoid opening doors and windows as much as possible to keep the cool air in the room.

Do not let direct sunshine enter the room when the air conditioner is in operation.

Blockages in the air filter reduce the airflow and lower cooling and dehumidifying effects. Clean at least once every two weeks.

When the air conditioner is not

going....

When air conditioner is not going to be used for a long time.

- Operate the air conditioner at the following

settings for 2 to 3 hours.

Type of operation: Fan operation mode.(Refer to page 20.)

This will dry out the internal mechanisms.

- Turn off the breaker.

CAUTION

Turn off the breaker when the air conditioner is not going to be used for a long time. Dirt may collect and may cause a fire.

Adjust the vertical and horizontal airflow direction to ensure a uniform temperature in the room.

Since windows are kept closed, it is a good idea to open them and ventilate the room now and then.

Helpful information

The air filters and your electiric bill. If the air filters become clogged with dust, the

cooling capacity will drop, and 6% of the electricity used to operate the air conditioner will be wasted.

When the air conditioner is to be used again.

- Clean the air filter and install it in the indoor

unit. (Refer to page 27 for cleaning it.)

- Check that the air inlet and outlet of the in-

door/outdoor unit are not blocked.

- Check that the ground wire is connected cor-

rectly. It may be connect to the indoor unit side.

- Remove the batteries from the Remote Con-

troller.

MAINTENANCE AND SERVICE

User must carry routine checkup & cleaning to avoid unit’s poor performance. In case of special situat

ion, the job must be carried out by service person only.

The air conditioner does not operate.

The room has a peculiar odor.

It seems that condensation is leaking from the air conditioner.

Air conditioner does not operate for about 3 minutes when restart.
