MOUNTING AND SET-UP

The fan is designed for vertical or horizontal installation and connection to a ventilation shaft or a round air duct of a

matching diameter (Fig. 2).

Caution! In case of vertical mounting the fan must be protected against ingress of rainfalls and condensate

inside the fan. Fan installation with direct air discharge upwards is not allowed (Fig. 2). The fan mounting

sequence is shown in Fig. 3-11. The fan wiring diagrams and operation algorithm are shown in g. 12-32.

Caution! Only for Quiet-Disc 150, Quiet-Disc 150 V, Quiet-Disc Extra 150, and Quiet-Disc Extra 150 V models.

Parallel power supply to the terminals 1 and 2 (Fig. 12) is not allowed! That will result in the fan breakdown. The operating

mode selection for the Quiet-Disc 150/Quiet-Disc Extra 150 T, TH, VT, VTH, and TP models is shown in Fig. 25.

Caution! Only for Quiet-Disc 100/125 T1 and Quiet-Disc150/Quiet-Disc Extra 150 T, TH, VT, VTH, and ТР models.

If the turn-on delay timer was activated by the external switch, light switch, motion sensor or the humidity sensor and during

the timer countdown the triggered action is cancelled, the external switch is turned oﬀ, the motion is no more detected or

the indoor humidity level drops down below the set point then the fan operates in the previous operation mode.
