Wire connection change of fan motor
This duct is composed of 3 fan motors.
To change external static pressure by duct resistance, connect the 3 connectors of the orange lead wires that are
connected to the underside of the fan tap changing terminal block to the same number (F1, F2 or F3) terminal.
The wires of the fan motor has been connected to (F2) [External static pressure 14 mmAq (137 Pa)] as factory default.
* Do not use F4.
NOTE
When the external static pressure is changed, write down the static pressure once change in the wiring diagram of the indoor unit is made.
