Make sure that the seal of the filler cap is not damaged and that
they sit properly. Replace it if necessary

l

Screw on the filler cap again

Checking the colour of the oil

NOTE

: The oil must be clear and transparent. A permanent milky co-

lour is an indication for contamination by foreign bodies. A dark colour
is an indication for oil that has been chemically altered or contaminated
by foreign bodies.

WARNING

Dark colored oil may indicate a hazardous pump condition which
could cause personal injury.

If dark oil similar to the example shown is observed, you have to
contact the Busch Customer Service without delay.

Oil change

DANGER

If the vacuum pump has pumped gases that were contaminated
with foreign bodies that are hazardous to health, the oil is also
contaminated with these foreign bodies.

There is a health hazard when changing contaminated oil.

There is also a danger to the environment.

Wear protective clothing when replacing contaminated oil.

Contaminated oil must be treated specially and must be disposed
of according to applicable regulations.

Draining used oil

NOTE

: After switching off the vacuum pump at normal operating tem-

perature wait no more than 20 minutes before the oil is drained.

l

Make sure that the vacuum pump is switched off and cannot
accidentally be switched on again

l

Make sure that the vacuum pump is vented to atmospheric
pressure

l

Put a drain tray underneath the oil drain plug

l

Unscrew the oil drain plug

l

Drain the oil

When the oil flow has stopped:

u

Refit the oil drain plug

l

Switch on the vacuum pump for a few seconds

l

Make sure that the vacuum pump is switched off and cannot
accidentally be switched on again

l

Remove the oil drain plug again and drain any remaining oil

l

Carefully unscrew and remove the magnetic plug

l

Check that no metal swarf sticks to the magnet of the magnetic
plug, clean if necessary

l

Make sure that the sealing washer of the magnetic plug is not
damaged, replace it if necessary

l

Refit the magnetic plug and tighten up

l

Make sure that the sealing washer on the drain plug is undamaged
and correctly positioned, replace it if necessary

l

Refit the oil drain plug and tighten up

Dispose of the used oil according to applicable regulations

CAUTION

Because of wear and tear of the seal, it is recommended to replace
the drain plug whenever the oil is changed.

Filling in new oil

l

Prepare the quantity of oil needed (see “Oil type/ quantity”)

WARNING

The use of chemically contaminated or polluted oil can lead to ha-
zardous pump conditions which could cause personal injury.

NOTE

: The quantity of oil specified in the installation handbook is of

informative nature only. Check the oil level with the help of the oil
sight glass on the vacuum pump.

l

Make sure that the drain plug has been fitted properly and that
they do not leak

CAUTION

Only fill in oil through the oil filler opening.

l

Unscrew the oil filler cap (OFP)

l

Fill in oil up to the middle of the oil sight glass

l

Make sure that the oil level lies between the MIN and MAX
markings on the oil sight glass

l

Make sure that the seal of the filler cap is not damaged and that it
sit properly. Replace it if necessary

l

Screw on the filler cap again

Checking the cooling water

Checking the cooling water flow

l

Check the cooling water flow regularly

If the flow drops, check for leaks

u

Make sure that the specifications of the cooling water are fol-
lowed

Checking the nitrogen

Checking the nitrogen flow

l

Check the nitrogen flow regularly

If the flow drops, check for leaks

u

Make sure that the specifications of the nitrogen are followed

Checking the current consumption

l

Check the current intensity of the motor

An increased intensity is an indication for a fault (see “Troubleshoo-
ting”)

Checking the sound absorber
(accessory)

l

Make sure that the condensate does not collect at the exhaust of
the vacuum pump

l

Drain the condensate at the drain opening and collect it in a
container
