Page 6: General Safety Precautions
The safety precautions listed herein are limited solely to using the MRF. The MRF has been designed and constructed in accordance with the current state of the art and recognized safety regulations. Nevertheless, hazards may be posed to the life and limb of the individual using the unit or to third parties. -
Page 7: Basic Symbols
This information helps you to optimally utilize all the features offered by your MRF. Proper/Designated Use The MultiRheo Filter MRF is a stationary filter unit used for full flow and bypass flow filtering from low viscosity fluid. Any use deviating from what is specified herein shall constitute improper use. -
Page 8: Training And Instruction Of Personnel
The MRF may only be operated by properly trained and instructed personnel. The areas of responsibility of your staff must be established in a clear-cut manner. Staff undergoing training may not use the MRF unless supervised by an experienced staff member. -
Page 9: Modifications To The Mrf
General Safety Precautions 1.11 Modifications to the MRF Do not make any modifications (design modifications, extensions) to the MRF without the prior consent of the manufacturer. Immediately replace any machine components which are not in perfect condition. Only use original (OEM) spare parts and consumables. When using non-OEM components it cannot be ensured that they have been designed and manufactured so as to comply with loading and safety requirements. -
Page 10: Transportation & Packing
