2.1 

PREPARATION AND TRAINING OF STAFF

 

The personnel involved in the installation, operation, maintenance and control of the equipment must 

be properly trained so as to carry out their tasks as effectively as possible. The responsibility, skills and 

supervision of the personnel fall within the remit of the employer. If the staff do not have the appropriate 

knowledge, they must be duly trained. If required, the employer may receive proper training directly from 

EBARA or from the distributor of this equipment.

2.2 MAINTENANCE

No technical or structural changes to the equipment are permitted without prior approval from EBARA. 

Only genuine spare parts and accessories authorized by EBARA are suitable for meeting safety standards. 

Rebuilding, modifying or using other spare parts may lead to the invalidation of your warranty.

Sound operation of the equipment depends on whether it is being used in accordance with the instructions 

given in this instruction manual. The working conditions and limits set out in this manual may not be 

exceeded in any way.

Always keep the nameplates legible and in good condition because the details shown will be needed for 

future reference or to request spare parts.

3. TRANSPORT AND STORAGE

If necessary, the equipment must be handled and stored in appropriate packaging. It must not be stored 

in damp environments with strong variations in temperature or in corrosive atmospheres. Condensates 

may attack the seal areas, metal parts and its electrical operation. In this case, any claims made under the 

warranty will be refused.
