ATTENTION

About Batteries

• When replacing the batteries, use batteries of the same type, and replace both batteries at the same time.
• When the system is not used for a long time, take the batteries out.
• The batteries will last for approximately 1 year. If the remote controller display begins to fade and the degradation of reception performance occurs within a year, however, replace both batteries with new, size AAA.LR03 (alkaline).
• The attached batteries are provided for the initial use of the system.
• The usable period of the batteries may be short depending on the manufactured date of the air conditioner.

About remote controller

• Never expose the remote controller to direct sunlight.
• Dust on the signal transmitter or receiver will reduce the sensitivity. Wipe off the dust with a soft cloth.
• Signal communication may be disabled if an electronic-starter-type fluorescent lamp (such as an inverter-type lamp) is in the room. Consult the shop if that is the case.
• If the remote controller signals happen to operate another appliance, move that appliance somewhere else, or consult the service shop.

Celsius/Fahrenheit display change function of the remote controller

• The set temperature may increase when the display is changed to Celsius from Fahrenheit because a fraction of 0.5°C is rounded up.
• Example: A set temperature of 64°F (equivalent to 18.5°C) will be converted into 19°C.
• When the display is changed to Fahrenheit again, the set temperature will be converted to 66°F (equivalent to 19°C) instead of the original set temperature (64°F) but a set temperature of 66°F (equivalent to 19°C) will be converted into 19°C with no temperature change.
• A reception sound will go off for the transmission of the set temperature to the indoor unit at the time of setting the Celsius/Fahrenheit display change function.

• Use this when making the noise quieter.
• The unit might lose capacity when the airflow rate is set to a weak level.
• Each pressing of the button advances the airflow rate setting in sequence.

NOTE
Notes on HEAT operation

•  Since this air conditioner heats the room by taking heat from outdoor air to indoors, the heating capacity becomes smaller in lower outdoor temperatures. If the heating effect is insufficient, it is recommended to use another heating appliance in combination with the air conditioner.
• The heat pump system heats the room by circulating hot air around all parts of the room. After the start of the HEAT operation, it takes some time before the room gets warmer.
• In HEAT operation, frost may occur on the outdoor unit and lower the heating capacity. In that case, the system switches into defrosting operation to take away the frost.
• During defrosting operation, hot air does not flow out of the indoor unit.

Note on the COOL operation
This air conditioner cools the room by blowing the hot air in the room outside, so if the outside temperature is high, the performance of the air conditioner drops.

Note on DRY operation
The computer chip works to rid the room of humidity while maintaining the temperature as much as possible. It automatically controls temperature and airflow rate, so manual adjustment of these functions is unavailable.

Notes on AUTO operation

• In AUTO operation, the system selects a temperature setting and an appropriate operation mode (COOL or HEAT) based on the room temperature at the start of the operation.
• The system automatically reselects the setting at regular intervals to bring the room temperature to a user-setting level.

Note on FAN operation
This is valid for fans only.

Note on airflow rate setting
