Concealed Duct High Static Pressure

Installation Manual

 

!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 137Pa (14mmAq)] as factory default.
