nate the cause of failure. Wait approx. five minutes before

restarting the pump.

•

Note

: In case of

supply voltage below 115 V

, the lock

of the cutout might be impaired and the pump may

restart on its own after sufficient cooling down. Take

appropriate precautions, if an automatic restart of the

pump may lead to a dangerous situation (e.g., switch

off the pump and disconnect from the power source).

Maintenance and repair

In order to comply with laws (occupational, health and

safety regulations, safety at work law and regulations for

environmental protection) vacuum pumps, components

and measuring instruments can only be returned when

certain procedures (see section „Repair - Maintenance -

Return - Calibration“, pg. 70) are followed.

Take advantage of our service seminars, which put special

focus on the maintenance and repair of vacuum pumps.

For details and for the online ”Instructions for repair” man-

ual see www.vacuubrand.com.

In normal use, the lifetime of the diaphragms and valves

is typically 15,000 operating hours. Bearings have a typi-

cal durability of 40000 h. Motor capacitors have a typi-

cal durability in the range of 10000 to 40000 h depending

strongly on operation conditions including ambient tem-

perature, humidity or load.

➨

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 five seconds

before starting

maintenance to allow the capacitors to discharge.
