Page 3: Technical Description
• The coupling must only be operated in normal industrial atmospheres. Since aggressive media may attack the coupling components, screws and elastic buffer rings, they repre- sent a risk for the operational safety of the coupling. Consult RINGFEDER POWER TRANSMISSION in such cases. -
Page 4: Storage
The coupling parts can be stored in their delivered standard-state for 6 months in a dry, roofed place at normal room temperature. For a longer storage duration a long-term preser- vation is necessary (consult RINGFEDER POWER TRANSMISSION). The elastic intermediate ring must not be subjected to ozone containing mediums, direct solar influence or strong light sources with ultraviolet-light. -

Page 13: Operation
When operating the coupling, its specific technical data has to be carefully observed (see chapter 6 ‘Technical Data’). These values must never be exceeded without the prior written approval by RINGFEDER POWER TRANSMISSION.In order to ensure trouble-free and reliable performance of the coupling, the coupling has to be designed according to the selection specifications, e.g. - Page 14 Check coupling parts for damages products change.
