Wear parts have to be replaced regularly.
+
Never operate a defective or damaged pump.
+
Check every motor capacitor regularly by measuring
its capacity and estimating its time in operation. Re-
place old capacitors early enough to prevent a failure in
operation. If an old motor capacitor fails, the capacitor
may get hot. It may even melt or emit a flame, which
could be
dangerous for persons and equipment in
the vicinity. The capacitors have to be replaced by an
electrician.
+
Vent the pump before starting maintenance. Isolate the
pump and other components from the vacuum system.
Allow sufficient cooling of the pump. Separate the pump
from the coolant circuit and drain condensate, if appli-
cable.
Ensure that
maintenance is done only by suitably trained
and supervised technicians. Ensure that the maintenance
technician is familiar with the safety procedures, which re-
late to the products processed by the pumping system.
Only dismantle the pump as far as necessary.
