In normal use, the lifetime of the diaphragms and valves is

typically 15,000 operating hours. Bearings have a typical

durability of 40000 h.

➨

Ensure that the pump cannot be operated acciden

tally. Never operate the pump if covers or other

parts of the pump are disassembled.

➨

Switch off the pump. Disconnect the electrical

power cord and wait two minutes

before starting

maintenance to allow the capacitors to discharge.

➨

Note

: The pump may be contaminated with process

chemicals, which have been pumped during operation.

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.

Vent the pump before starting maintenance. Isolate the

pump and other components from the vacuum system.

Allow sufficient cooling of the pump.

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.
