If the pump does not achieve the ultimate vacuum:
- Whenever the diaphragms and valves have been replaced, a break-in
period of several hours is required before the pump achieves its ulti-
mate vacuum.
- In case of an unusual noise, switch off pump immediately and check
clamping disc positions.
If the specified ultimate vacuum is not achieved, and if this does not
change after the break-in period:
Check hose connectors at pump heads for leaks. If necessary recheck
valve seats and pump chambers.
