➨

Never operate the pump if covers or other parts of the

pump are disassembled. Ensure that the pump cannot

be operated accidentally.

➨

Isolate equipment from power supply before re-

moving the cover!

➨

Before starting maintenance, unplug the equipment and

wait 5 seconds to allow the capacitors to discharge.

➨

Attention: The pump might be contaminated with nox-

ious or otherwise dangerous process chemicals that

have been pumped during operation. Ensure that the

pump is decontaminated before maintenance.

Take adequate precautions to protect people from the

effects of dangerous substances if contamination has

occurred. Wear appropriate safety-clothing when you

come in contact with contaminated components.

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 operation time. Exchange

old capacitors early enough to prevent a failure. When

motor capacitors fail, they can get hot enough to melt

or cause a flame which could be

dangerous for per-

sons and equipment in the vicinity. Motor capacitors

have to be replaced by an electrician.

Before starting maintenance, vent the system and al-

low sufficient cooling of the pump. Drain condensate, if

applicable. Avoid the release of pollutants.

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.

In order to comply with law (occupational, health and safe-

ty regulations, safety at work law and regulations for en-

vironmental protection) vacuum pumps, components and

measuring instruments returned to the manufacturer can

be repaired only when certain procedures (see section

”Notes on return to the factory”) are followed.
