APPLICATION AND OPERATING CONDITIONS

The fan is designed for wall and ceiling mounting
Bathroom extractor fans are designed to transport normal or slightly dusty air (particle size <10 μm) of low aggressiveness and humidity in temperate climates according to and within their limits of performance
The appliance is designed only for continuous operation in a building if there is no access to the power supply line
The maximum temperature handled by the bathroom extractor fan and the maximum ambient temperature are +40°C
The exhaust fan is an IP24 and protection class II device if it is installed in the wall or ceiling according to Figure 7.
The bathroom extractor fan must be operated according to its intended use and in accordance with the data provided on the rating plate
The bathroom extractor fan must be connected to the building mains (recessed electrical installation) with one of the following power cable: 2x1,5 mm²; 3x1,5 mm², depending on the fan version - see PRODUCT DATA chapter. If a cable with more wires is used, eg 4x1,5mm², the outer diameter of the cable must not exceed 14,5 mm
The bathroom extractor fan cannot be used to circulate air with the following characteristics:
- viscous contaminants prone to deposition in the bathroom extractor fan,
- corrosive contaminants which may degrade the bathroom extractor fan,
- contaminants from mixtures of flammable substances in the form of gases, vapours, mists and dusts, which in combination with air can create an explosive atmosphere
Motors fitted with ball bearings are designed for a service life of at least 30,000 hours at maximum permissible ambient temperature so as to enable continuous operation at maximum efficiency
In case additional controllers exist in the installation, these must not cause frequent switching on and off of the bathroom extractor, as this will be considered extreme and not intended use of the product
The device is not suitable for use 2000 m above sea level

TRANSPORT AND STORAGE

PRODUCT DATA

Terminal block (standard version, no part index suffix). Models with terminal block should be connected according to the wiring diagram in Fig. 3.

The bathroom extractor fan is operated by means of a separate switch, which is part of the building electrical installation (not part of the appliance)
Humidity sensor and timer (part name suffix "DH"). Models equipped with humidity sensor (hygrostat) and stop delay (timer) should be connected according to the wiring diagram in Fig. 4 or 5.

The air humidity sensor detects humidity between 40% ("HIGRO" potentiometer turned maximum to the left) and 90% ("HIGRO" potentiometer turned maximum to the right) of relative humidity (see Fig 8.1)

The system is additionally equipped with a timer The operation of the fan depends on the power supply connection method If connected as shown in Fig5, the fan will start automatically when the air humidity level exceeds the set value of the humidity sensor Under these conditions the fan will switch off when the air humidity level is below the set value, plus the switch-off delay time set with the timer elapses Switch-off delay time is regulated by the "CZAS/TIME" potentiometer in the range of 3-30 min (the minimum switch-off delay time is obtained by turning the potentiometer maximum to the left - see Fig 8.2)

If connected as shown in Fig 4, the fan can also be started with by operating the separate on/off switch Depending on the setting of the "DELAY" slider (13) on the controller, the fan will start operating when voltage is detected on the "SL" terminal or after 2 minutes after voltage is detected After a signal loss at the "SL" terminal due to switching off the light or the on/off switch, the fan will stop after the stop delay time set with the potentiometer if the humidity level in the room is below the level preset on the potentiometer The humidity detection system is the master system
NOTE: When the green diode located in the electronic system is on, it means that the humidity level in the room is higher than the preset on the potentiometer controlling the humidity level adjustment. As long as the diode is on, the fan will not start counting down the stop delay after which the fan is switched off. It will take place only after the humidity level in the room drops and the green diode goes off.
