MOUNTING
The fan is suitable both for horizontal or vertical mounting on the floor, on the wall or on the ceiling (Fig. 1).
The fan can be installed independently or as part of a set with parallel or in-series connection (Fig. 2).
Install minimum 1 m long air duct on the intake spigot side in case of horizontal fan mounting or a hood in
case of vertical fan mounting.
The outlet spigot must always be connected to the air duct. The fan mounting sequence is shown in Fig. 3-11
and 14-19.
The fan wiring diagrams are shown in Fig. 12-13. Some fan models are equipped with a plastic limit stop in
front of the L1 terminal. Remove the limit stop for connection to the L1 terminal.
