NOTES:

 Specifications are based on the following conditions:

– Cooling: Indoor temperature of 27 °CDB/19 °CWB, and outdoor temperature of 35 °CDB/24 °CWB. – Heating: Indoor temperature of 20 °CDB/15 °CWB, and outdoor temperature of 7 °CDB/6 °CWB. – Pipe length: 5 m, Height difference: 0 m. (Between outdoor unit and indoor unit.), Standard static pressure; 18 type and 24 type: 35Pa, 30 type: 47Pa

 Protective function might work when using it outside the operation range.  *1: Maximum current:

– The maximum value when operated within the operation range. – The total current of indoor unit and outdoor unit.

 *2: Sound pressure level:

– Measured values in manufacturer’s anechoic chamber. – Because of the surrounding sound environment, the sound levels measured in actual installation conditions might be higher than the specified values here.

 Automatic airflow adjustment procedures

1. To start the auto setting, use No.32 of setting value in Function Number 26.

2. Run the air conditioner on fan mode (High). * For instructions on how to operate the air conditioner, refer to the operation manual of the remote controller. During automatic airflow adjustment, the mode will be fixed at fan (High). When this function is active, do not operate the outdoor unit.

3. The air conditioner will run for about 1 to 8 min then stop automatically. * Do not change the throttles of the inlet and outlet ports during operation. When used in a group control system, the setting will take about 10 min.

4. Turn the air conditioner off and on again.

5. Check the setting value of Function 26. * If the setting value has not changed, repeat the procedure from step 2.

CAUTION

When the duct or outlet installations are changed after the Automatic airflow adjustment is completed, repeat the procedure from step 1.

NOTES:

• If the space is larger than stated above, the condition will be the same as when there is no obstacle.

• Height above the floor level should be 50 mm or more.

• When installing the outdoor unit, be sure to open the front and left side to obtain better operation efficiency.

CAUTION

• When the outdoor temperature is 0 °C or less, do not use the accessory drain pipe and drain cap. If the drain pipe and drain cap are used, the drain water in the pipe may freeze in extremely cold climate. (For reverse cycle model only.)

• In area with heavy snowfall, if the inlet and outlet of the outdoor unit is blocked with snow, it might become difficult to get warm, and it is likely to cause product malfunction. Construct a canopy and a pedestal, or place the unit on a high stand that is locally installed.
