•
The air exhaust fan is intended for handling indoor air of normal quality or with a low dust content (with a particle size < 10 μm) and of low aggressiveness and
humidity. The air exhaust fan is intended for operation in temperate climate conditions and within the performance limits specified in the product catalogue.
•
The air exhaust fan may be operated only in a permanent indoor installation and with its power supply line concealed.
•
The maximum temperature of the medium handled by the air exhaust fan and the maximum ambient temperature are +40°C.
•
The air exhaust fan is an IPX4 and protection class II device.

The fan must be operated according to its intended use and within the performance limits specified on the nameplate.
•
Connect the air exhaust fan to the building mains (electrical system) with the following power cable: H03VV-F (OMY) 2x1,5 mm² or H03VV-F (OMY) 3x1,5 mm²),
maximum outer diameter 7,5 mm, depending on the optional accessories provided (does not apply to the models with the supply cable attached).
•
Do not use the air exhaust fan to handle the air with the following content:
- viscous contaminants prone to deposition in the fan,
- corrosive contaminants which may degrade the fan,
- flammable contaminants, including gas, vapours, mists or particulates which may form explosive mixtures with air.
•
The devices equipped with ball bearings are designed for a minimum operating life of 30,000 hours in S1 duty cycle at the maximum power output and the maximum
ambient temperature.
•
The control system must prevent extremely frequent power cycling.
