Ensure that the pump is completely decontaminated
before maintenance commences.
+
Take adequate precautions to protect people from the
effects of dangerous substances if contamination has
occurred. Use appropriate protective clothing, safety
goggles and protective gloves.
+
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 capaci-
tor 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. Drain condensate,
if applicable.
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.
