4-3. Fan Characteristics
Current value as a criterion, adjust the air volume value to become within the range of the chart below.
REQUIREMENT
Install the volume damper in the air outlet, and adjust the airflow to become within the range of the chart above.
n Wire connection change of fan motor
Wiring connection of the fan motor is connected that external static pressure makes to 200P during factory setting.
In cases where external static pressure is required to change by the duct resistor, change the wiring connection.
The fan motor connector is connected to the 9P white color connector during factory setting.
When the fan motor is set to high static pressure, connect to the 9P red color connector such as arrow mark.
In addition, 9P red color connector is bundled along with wirings into the electric parts box.
