before production. 
Any change in the conditions of use is only permissible after approval by COLASIT; otherwise this will entail 
loss of warranty.

The fan must be deployed and used in accordance with the conditions mentioned 
in this operating manual. Only in this way can its function be guaranteed and 
dangers to persons and material be excluded during operation. We accept no 
liability nor guarantee any claims for damages arising from nonobservance of this

1.4 

Safety review 

 

After installing the fan, we recommend the operator conducts a review of the entire operational environment. 
In this way it can be guaranteed that neither the fan will suffer damage nor that the fan will cause any 
damage. 
 

1.5 

Personnel qualifications 

 

The fan may only be put into operation, handled, operated, maintained and cleaned by trained personnel 
who are authorised (and competent) to carry out such work. 
The personnel must possess the appropriate skills needed to operate the fan and be familiar with the effects 
of the reactions caused by the fan. 
The personnel qualified to operate the fan must be able to react adequately and correctly in case of a fault or 
an emergency. 
 

1.6 

Possible emergencies 

 

An emergency may result from the bursting or melting of plastic components as a result of mechanical 
damage or chemical and thermal influences. In this case, parts may fly off or vapour may be produced that 
may be hot, corrosive, poisonous, irritating or inflammable (e.g. hydrochloric acid vapour occurring from 
burning PVC). 
There may be a danger of fire under certain circumstances. 
For the choice of the correct fire-extinguishing devices and the positioning of the firefighting equipment, 
please follow the recommendations of your local fire station.
