MOUNTING
The fan is designed for top or horizontal installation and connection to a ventilation shaft or a round air duct of a matching
diameter, fig. 2.
Attention!
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. 3.
The fan mounting sequence is shown in fig. 4-12.
The fan wiring diagrams are shown in fig. 13-16, 18-20, 23-29.
Warning! Applicable only for 150 Quiet and 150 Quiet V.
Parallel power supply to the terminals 1 and 2, Fig. 21, is not allowed! That results in the fan breakdown.
The operating mode selection for the fans 150 Quiet T, TH, VT, VTH, TP are shown in fig. 22.
The visual operation indication for the fans 150 Quiet T, TH, VT, VTH, TP is shown in fig. 31.
Adjustment of the turn-off delay timer, the turn-on delay timer and the humidity sensor is shown in fig. 17, 30.
Warning! Only for 150 Quiet T, TH, VT, VTH, TP.
If one of the following events that actuated the turn-on delay timer operation (from 0 to 120 seconds):
power voltage cut-off to the input terminal 1;
no motion detection more in the premise;
humidity drop below the set level;
ceased to exist during its countdown, the fan remains in the previous operation mode.
MAINTENANCE
The fan maintenance periodicity is at least once per 6 months.
To clean the fan use a soft cloth or a brush wetted in a mild detergent solution, fig. 32-37.
WARNING!
Avoid water dripping on the electric components.
Wipe the fan surfaces dry after cleaning.
