Tab.12 *To reduce the surface temperature of the pump heads and to extend the
service life of the diaphragm, you can optionally attach a water cooling system (see
Chapter 6.5 Connecting water cooling (optional)).
**The gas tightness of the pump head is no longer ensured after the pump head is
opened or after changing diaphragm and reed valves. A leak test can be used to
determine whether the original gas tightness is again achieved.
***Values apply for helium leak test
Additional equipment
The pump is equipped with a safety diaphragm.
