page 33 of 57The diaphragms and valves will be damaged, if liquids arepumped in significant amounts.Check the pump regularly for external soiling and depos-its. Clean the pump if necessary to avoid an increase ofthe pump’s operating temperature.In case of overload, the motor is shut down by a self-holdthermal circuit breaker in the winding.Note: Only a manual reset is possible. Switch off thepump and disconnect the electrical power cord. Identifyand eliminate the cause of failure. Wait approximately fiveminutes before restarting the pump.• Note: In case of supply voltage below 100V, the lockof the breaker may not latch and the pump might restarton its own after sufficient cooling. Take appropriate pre-cautions, if an automatic restart of the pump may leadto a dangerous situation.A warm up period (approximately 15 min.) is required to en-sure that the rated ultimate vacuum and pumping speed areattained. Avoid overheating (e.g., due to hot process gases).Important notes regarding the use of gas ballastGas ballast is a continuous purge to keep the pump’s in-terior as clean as possible and to reduce the possibility ofcondensation inside the pump.➨ Air and pumped media might react inside the pump orat the outlet of the pump and form hazardous or explo-sive mixtures, when you use air rather than inert gasfor the gas ballast. This constitutes a risk of significantdamage to equipment and/or facilities, a risk of person-al injury or even loss of life.+ Make sure that air/gas intake through the gas ballastvalve can never lead to hazardous, explosive or other-wise dangerous mixtures. If in doubt, use inert gas.NOTICE
