Page 41: During Operation
page 41 of 68 During operation ➨ Vent and dispose of potentially dangerous gases or vapors at the outlet of the pump appropriately. + Due to the high compression ratio, the pump might generate overpressure at the outlet. Check pressure compatibility with system components (e.g., exhaust tubing or exhaust valve) at the outlet. - Page 42 page 42 of 68 Prevent internal condensation, transfer of liquids or dust. The diaphragms and valves will be damaged, if liquids are pumped in significant amounts. Check the pump regularly for external soiling and depos- its. Clean the pump if necessary to avoid an increase of the pump’s operating temperature.

This does not change the method of replacing diaphragms and valves. ➨... - Page 53 page 53 of 68 Ensure that maintenance is done only by suitably NOTICE trained and supervised technicians. The valves and diaphragms are wear parts. If the rated ultimate vacuum is no longer achieved or in case of in- creased noise level, the pump interior, the diaphragms and the valves must be cleaned and the diaphragms and valves must be checked for cracks or other damage.

Page 57: Assembling The Pump Heads
page 57 of 68 Assembling the pump heads ➨ Bring the diaphragms (F) into a position, in which they are in contact with the housing (J) and centered with respect to the bore. ➨ Put on head covers (D). + Pay attention to the correct orientation of the head covers: Align the nib at the head cover (D) with the notch of the housing cover (A). - Page 58 page 58 of 68 Replace diaphragms and valves of the opposite side of the pump in the same way! Checking the ultimate vacuum ➨ A fter any intervention at the equipment (e.g., repair / maintenance) the ultimate vacuum of the pump has to be checked. Only if the pump achieves its specified ultimate vacuum, the pump’s leak rate is low enough to ensure that no explosive atmospheres will occur in the inte- rior of the equipment.
