Correct installation of ATEX fan
The fan must be installed properly to guarantee trouble-free operation. To document proper installation, you
will find a form on the last pages of this operating manual. The fitter must confirm the proper installation item
for item on this form.
The signed form must be kept by the safety officer or operating company.
COLASIT also offers a comprehensive installation service for fans.

Shipping, unpacking, inspection, storage
The fan is completely assembled and can be delivered in a closed film wrapping.
Please make sure the delivery corresponds to the shipping documents.
Please examine the packaging for external damage and report any damage
immediately to the transport company, the supervisor and the manufacturer.
Please handle the fan with care. During transportation, only apply strain on the steel parts. Plastic is
sensitive to impact and knocks, especially in the temperature range under +5°C.
When the film is removed, the intake and pressure nozzles are open and
unprotected against the intrusion of foreign objects. Therefore, please do not
remove the protective film until shortly before final installation.
Storage
If the fans are not put into operation immediately, store them in a clean dry place
where they are protected from impacts, vibrations, and temperature fluctuations
and where the air humidity is under 90%.
If these storage conditions are not available, switch the fans on at regular intervals
to exclude the risk of condensate forming. Before switching on, unscrew the
condensate drain plugs each time and replace them afterwards.
