fan must be capable of breaking live voltage
contact on all switching poles to fully isolate the
fan from power during Category III overvoltage
conditions, in accordance to applicable electrical
engineering regulations.
• The ventilator is designed for installation at a
substantial height, i.e. 2.3 m above the floor. The
fan shall only be installed in a position and an
orientation specified in the Operating Manual,
given the necessary entry of the power cable into
the fan housing.
• Before servicing the fan, isolate it from the mains voltage with the circuit breaker. Secure the circuit breaker
against inadvertent operation.
• The fan installation design must prevent reverse flow of flue gas into the room from open flue gas exhaust
ducts and appliances operated with open flames.
• Never attempt to modify or alter the fan without authorization.
• Before installing the fan, verify the load bearing capacity of the installation substructure. Improper installation
fastening may result in damage or failure of the fan and hazards to the people nearby.
The fan can be hazardous when operated against its intended use or installed by unqualified
personnel.
Application and operating conditions
• The central fan is intended for handling indoor air of normal quality or with a low dust content (with a particle
size < 10 μm) with low aggressiveness and humidity. The central fan is intended for operation in temperate
climate conditions and within the performance limits specified in the product catalogue.
• The central fan may be operated only in a permanent indoor installation.
• The maximum temperature of the medium handled by the air exhaust fan and the maximum ambient
temperature are +40°C.
• The central fan is an IPX2 and protection class I device.
• The fan must be operated only according to its intended use and within the performance limits specified on
the nameplate.
•
Connect the fan to the building mains (electrical system) with the following power cable: NYM-O 5x1.5
mm² (H07V-K 5x1.5 mm²) or with two NYM-O 3x1.5 mm² (H07V-K 3x1.5 mm²) cables, depending on the
optional accessories provided.
• Do not use the 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.
