Applications
Duct fan is ideal solution for bathrooms and toilets. It is used to assist natural ventilation and may be installed in rooms that are equipped with individual ventilation ducts, in collective residential buildings and public use, except of rooms inside which there may occur the atmosphere that causes corrosion or explosion. 

• The equipment is not intended for use by persons (including children) with reduced physical, sensory and mental ability.
• The equipment is not designed for children to play.
• In accordance with PN-HD-60364 standard, this fan cannot be installed in 0 and 1 protection zone in rooms equipped with bath or shower.

METHOD OF INSTALLATION AND OPERATION
The duct fan shall be installed in place of a ventilation grate using rawlplugs, with holes located in the body of the fan, prepared for this purpose. In the case of through fans, this fan constitutes a part of the ventilation system. Fans equipped with a cord including a plug and a switch shall be activated by inserting the plug into the outlet of 230V ~ and the corresponding attaching of a connector coupler. Fans in B version, equipped with circuits (T, HT, FT, VT, VHT, VFT) shall be connected directly to the electrical system, using a terminal strip with LN terminals or circuits with LNS terminals.

NOTE: Connection to the mains must be performed by a person authorized to operate the electrical installation, after power is turn off.

- The fan equipped with a pull switch allows for temporary enabling and disabling the fan by pulling a string located at the bottom of the fan.
- A fixed enclosure shall be evenly adhered to a surface of the wall in order to avoid its deformation.
- You should take appropriate measures to prevent the reverse flow of gases into the room from an open chimney hole or other devices with open fire.
- In the case of fans connected to the network permanently, the electrical installation must be equipped with a switch, in which the distance between the contacts of all the poles shall not be less than 3 mm.

NOTE: Regulation of setpoints of fans with electronic circuits can be made only after disconnecting the power supply (e.g. by turning off the fuse in the circuit, by which the fan is to be powered). For switching fans equipped with electronic circuits you should not use switches with neon or LED diode.

T – fan with a timer
Control of the fan activation requires connecting a controller to the electric switch. For this purpose, you can use an existing light switch of a ventilated room fig.3  I version of the fan connection or an additional, independent switch controlling the fan activation fig. 3  II version of the fan connection . After turning off the switch W/WO fig. 3 the fan continues to work for a delay time for turning off, set in the fan controller. The set time is counted from the moment of switching off the W/WO fig. 3. Time setting is made by setting a potentiometer of the control system in the desired position. The delay time can be set in the range from 0.5 to 30 min. 

VT – fan with a timer equipped with a COMFORT module
VT fan is equipped with T circuit and additionally equipped with a comfort module.

By using switches shown in fig. 2 you can set two speeds and choose one of two types of an automatic cycle. Switch 1 in ON position – the fan works in a silent mode. Switch 1 in OFF position – an engine works at high speed to ensure maximum efficiency of the fan. Switch 2 in ON position – enables turning off the fan at the time when the switch W/WO fig. 3 is turn off. The fan will activate in time after turning off the switch W/WO fig. 3 and will turn off after the time set on the T potentiometer.

Switch 2 in OFF position – the fan works at the time of activation of the switch W/WO fig. 3 The fan will turn into the time cycle after turning off the switch W/WO fig. 3 and turn off after the time set on the T potentiometer. 

NOTE: Turning the fan into a timer is indicated by flashing LED diode. 

VFT – fan with a photocell and a KOMFORT module
VFT circuit is equipped with VT circuit and additionally has a photocell controlling the level of lighting in a room.

Using switches shown in fig. 2 you can set two speeds and select one of two types of an automatic cycle. Switch 1 in ON position – the fan works in a silent mode, Switch 1 in OFF position – an engine works at high speed to ensure maximum efficiency of the fan. Switch 2 in ON position – enables turning off the fan at the time when the switch W/WO fig. 3 is turn on or when the photocell detects the light in a room. The fan will activate in time after turning off the light or the switch W/WO fig. 3 and will turn off after the time set on the T potentiometer.

Switch 2 in OFF position – the fan works at the time of activating the switch W/WO fig. 3 or at the time of detection of activation of lighting by the photocell. The fan will activate in time after turning off the light or the switch W/WO fig. 3 and will turn off after the time set on the T potentiometer.

Using the potentiometer F fig. 1 we can set a threshold of lighting. For rooms without dark windows it is recommended to set it at a minimum value, e.g. in lightly-illuminated rooms you place the potentiometer in the middle position, while in well-illuminated rooms it is recommended to set it at a maximum.

NOTE: The fan with the photocell is not suitable for use in rooms that can be illuminated (up to 5 lux) already before turning on the light, and so, e.g. in the case of rooms equipped with a window. In the case of LED lighting, the lighting power may be insufficient for the proper control of the electronic circuit.

HT – fan with a humidity sensor
HT circuit has all the features of T circuit, and is additionally equipped with a humidity sensor that allows running the fan in case of exceeding a preset humidity threshold. Activation of the fan is made automatically when the relative humidity near the fan reaches a set level or after activation of W/WO fig. 3. Turning off takes place after the set delay time, calculated from the moment of reaching the desired humidity level in the room or when turning on the switch W/WO fig. 3.

The fan equipped with the humidity sensor (HT) requires setting the humidity level of the room. The adjustment is performed by turning the H potentiometer fig. 1 to the position of an extreme (-). The fan starts working, and the LED diode lights continuously. By turning the potentiometer very slowly in the direction of (+), at some point the LED diode will start flashing. This is a required position of the humidity level of the room.

NOTE: The adjustment shall be done in a dry room before bathing or other operations using water.

VHT – fan with a humidity sensor and with a COMFORT module
VHT circuit has all the features of VT circuit, and is additionally equipped with a humidity sensor that allows running the fan in case of exceeding a preset humidity threshold. Activation of the fan is made automatically when the relative humidity near the fan reaches a set level or after activation of W/WO fig. 3. Turning off takes place after the set delay time, calculated from the moment of reaching the desired humidity level in the room or when turning on the switch W/WO fig. 3.

The fan equipped with the humidity sensor (HT) requires setting the humidity level of the room. The adjustment is performed by turning the H potentiometer fig. 1 to the position of an extreme (-). The fan starts working, and the LED diode lights continuously. By turning the potentiometer very slowly in the direction of (+), at some point the LED diode will start flashing. This is a required position of the humidity level of the room.

NOTE: The adjustment shall be done in a dry room before bathing or other operations using water.

Automatic shutter
After starting the fan, the completely open shutter time is about 30 seconds.
When the shutter is fully opened, the fully close shutter time, after switching off the fan, it is around 90 seconds.
