2.1 Specific conditions for safe use (1-5)
1. The fan’s rating plate displays the fan’s data at rated voltage. In order for the fan’s permitted current and power con-
sumption not to be exceeded the fan may need to be pressurised with a minimum back pressure according to table
1.
2. PTC protective circuits in the motors must be connected to monitoring apparatus certified according to ATEX Directive
that isolates the motor from voltage supply immediately when activated.
3. When fans are installed in a duct system, the duct system must meet enclosure classes IP20 at the inlet and outlet.
Components that contribute to the enclosure protection must be of suitable material and durability.
4. Fans are only intended for fixed installation. The motors’ connection cable on KTEX is secured with cable ties in order
to guide the cable correctly in relation to the hinge on the hatch. Attachment must be carried out so that the cable
can still be extended after fixing without the cable insulation being damaged.
5. Ambient temperature and temperature of transported air should remain within the range –20 to +40 °C. Fans must
not be run at flows below 200 m
3
/h at ambient temperature of 20 °C. There is otherwise a risk that the exhaust tem-
peratures are higher than the permitted ambient temperature.

3 Transport and storage
The fan is packed at the factory to withstand normal handling during transit. Avoid blows and shock loads. Store the fan
in a dry, dust-free place without damaging vibrations (v eff <0.2 mm/s) to avoid bearing damage. Avoid long storage
periods (we recommend max.1 year). Before installing the fan, check the motor bearings for noise (spin the impeller
carefully by hand).
Caution
• When handling the goods, use suitable lifting equipment in order to avoid damage to fans and personnel.
• Do not lift the fan in any cable, junction box or the impeller.
