Technical data

Design and functioning

The fan casing is made of plastic.
The extract spigot with a non-return valve is attached to the fan to prevent back air flow.
In the upper part of the casing there is a terminal box, which contains terminals for connecting the fan to power mains and to electronics board, if available.
A single-phase electric motor with a centrifugal impeller with forward curved blades is fastened inside of the casing.
Depending on the model, the fan is equipped with a timer and a humidity sensor.

Mounting and set-up

Read the user’s manual before installing the unit.

The fan is a component part and is not designed for stand-alone operation.
The fan is designed for ceiling mounting and installation in the floor slab with fastening to the ceiling surface using removable rotary clamping brackets on the fan casing.
The fan installation location must comply with local building codes for this type of product.
Check the fan for mechanical damages prior to mounting.
Before mounting make sure the casing does not contain any foreign objects (e.g. foil, paper).
While installing the unit ensure convenient access for subsequent maintenance and repair.
The minimum distance between the fan and the ceiling should be at least 5 mm.

Mounting sequence

Connection to power mains

Power off the power supply prior to any operations with the unit.
The unit must be connected to power supply by a qualified electrician.
The rated electrical parameters of the unit are given on the Manufacturer’s label.

Any tampering with the internal connections is prohibited and will void the warranty

The fan is rated for connection to single-phase AC 220-240 V/50 (60) Hz.
The fan is connected to power mains with an electric plug through a QF circuit breaker with a magnetic trip integrated into the fixed wiring system.
The position of the automatic circuit breaker must ensure free access for quick power-off of the unit.

Wiring diagram of the fan

Terminal designations on the wiring diagram: L – phase; N – neutral; S1 — switch; QF – automatic circuit breaker.

Electronics operation algorithm

Timer (T)
After turning on an external switch, such as a light switch, the fan turns on.
After the switch is turned off the fan keeps operating for a set turn-off delay time period, adjustable from 0 to 30 minutes.

Humidity sensor (TH)
If the set humidity level in the room is exceeded from 60 % to 90 %, the fan turns on.
As the indoor humidity level drops down the fan keeps operating for a set turn-off delay time period, adjustable from 0 to 30 minutes, and then turns off.

The fan delivery set includes a specially designed plastic screwdriver for fan settings adjustments.
Use it to change the turn-on and turn-off delay time and the humidity set point.

To adjust the fan turn-on delay time, turn the control knob Ton clockwise to increase and counter-clockwise to decrease the turn-on delay time respectively, adjustable from 0 up to 2 minutes.

To adjust the humidity set point, turn the control knob H clockwise to increase and counter-clockwise to decrease the humidity sensor set point, adjustable from 60% up to 90%

Do not use a metal screwdriver, knife, etc.
For adjustment operations not to damage the circuit board.

Technical maintenance

Disconnect the unit from power supply before any maintenance operations!
Ensure that the unit is switched off from the supply mains before removing the guard.

The fan maintenance includes regular cleaning of the surfaces of dust and dirt. Replace the filter as required, but at least every 6 months.
The impeller cleaning is shown below. Clean the impeller blades thoroughly every 6 months.
