Prior to Operation

Preparing for operation

1. Contact an installation specialist for installation.
2. Use a dedicated circuit.

Usage

1. 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.
2. Due to the possibility of oxygen deficiency, ventilate the room when used together with stoves or other heating devices.
3. 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.
4. While using the remote control, refer the user manual of that particular remote controller.

Cleaning and maintenance

1. Do not touch the metal parts of the unit when removing the filter. Injuries can occur when handling sharp metal edges.
2. Do not use water to clean inside the air conditioner. Exposure to water can destroy the insulation, leading to possible electric shock.
3. 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.

Service
For repair and maintenance, contact your authorized service dealer.

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 used again.

1. Clean the air filter and install it in the indoor unit.
   (Refer to page 9 for cleaning it.)

2. Check that the air inlet and outlet of the indoor/outdoor unit are not blocked.

3. Check that the ground wire is connected correctly. It may be connected to the indoor unit side.

Operation Tips

Do not overcool the room.
This is not good for the health and wastes electricity.
Keep blinds or curtains closed.
Do not let direct sunshine enter the room when the air conditioner is in operation.
Keep the room temperature uniform.
Adjust the vertical and horizontal airflow direction to ensure a uniform temperature in the room.
Make sure that the doors and windows are shut tight.
Avoid opening doors and windows as much as possible to keep the cool air in the room.
Clean the air filter regularly.
Blockages in the air filter reduce the airflow and lower cooling and dehumidifying effects. Clean at least once every two weeks.
Ventilate the room occasionally.
Since windows are kept closed, it is a good idea to open them and ventilate the room now and then.

Before you call for service…

Troubleshooting Tips! Save time and money!
Check the following points before requesting repairs or service…. If the malfunction persists, please contact your dealer.
The air conditioner does not operate.

• Has the fuse blown or has the circuit breaker been tripped?

The room has a peculiar odor.

• Check that this is not a damp smell exuded by the walls, carpet, furniture or cloth items in the room.

It seems that condensation is leaking from the air conditioner.

• Condensation occurs when the airflow from the air conditioner cools the warm room air.

• Has the temperature been set incorrectly?
• Are the indoor unit’s air inlet or outlet vents obstructed?

The air conditioner operation is noisy.

• For a noise that sounds like water flowing.
  -This is the sound of freon flowing inside the air conditioner unit.
• For a noise that sounds like the compressed air releasing into atmosphere.
  -This is the sound of the dehumidifying water being processed inside the air conditioning unit.

Crack sound is heard.

• This sound is generated by the expansion/constriction of the front panel, etc. due to changes of temperature.

Remote control display is faint, or no display at all.

• Are the batteries depleted?
• Are the batteries inserted in the opposite (+) and (-) directions?
