• Depending on the temperature of the uid transported and the operating con-
ditions, the surface temperatures of the accessible parts may be high and
appropriate precautions must be taken.
• When commissioning or operating the fan, there is a danger of suction. There-
fore, no loose clothing should be worn, nor should necklaces, jewellery, etc.,
be used that poses a risk of being sucked into the equipment. We recommend
tying back or covering long hair.
• Please note that the supplied fan is not completely watertight. Therefore, when
the fan has an open inlet and/or outlet (installation mode A, B, C according to
EN ISO 13349) the inside and outside of the fan must be in the same category.
In the case of installation mode type D (tubular inlet and outlet), there cannot
be more than one category of difference between the inside and outside (where
the motor is). For example, the conveyed air can be considered as zone 1 and
the outside air has to be at least zone 2 (unclassi ed zones are not allowed).
• The ILT ATEX fan range can only be used with the power supply and protection
devices chosen by the manufacturer in the speci c instruction manual for the
equipment.
Additional note for products supplied without a motor or transmission
• The installer must ensure that the complete assembly of the fan with the drive
and motor complies with the ATEX directive and the requirements of EN 14986.
