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
temperature wait no more than 20 minutes before the oil is drained.
l Make sure that the vacuum pump is switched off and cannot ac-
cidentally be switched on again
l Make sure that the vacuum pump is vented to atmospheric pres-
sure
l Put a drain tray underneath the oil drain plugs (ODP)
l Remove the oil drain plugs (ODP)
l Carefully remove the drain plugs
l Drain the oil
l Because of wear and tear on the seals replace the current drain
plugs with new ones
When the oil flow has stopped:
u Close the oil drain plugs (ODP)
l
Switch on the vacuum pump for a few seconds
l Make sure that the vacuum pump is switched off and cannot ac-
cidentally be switched on again
l Remove the oil drain plugs again and drain any remaining oil
l Check that no metal swarf sticks to the magnet of the drain plug,
clean if necessary
l Refit the oil drain plugs and tighten up
l Dispose of the used oil in compliance with applicable regulations
CAUTION
Because the ends of the drain plugs are magnetic, metal swarf can
stick to them. Always clean away this swarf when removing the
drain plugs.
Because of wear and tear of the seals, it is recommended to replace
the drain plugs 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
hazardous 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 va-
rious oil sight glasses on the vacuum pump.
l
Make sure that the drain plugs have 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 mar-
kings on the oil sight glasses
l Make sure that the seals of the filler cap are not damaged and
that they sit properly. Replace them 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 silencer (accessory)
l Make sure that the condensate does not collect at the exhaust of
the vacuum pump
l
Drain the condensate and collect it in a container
l Dispose of the condensate according to applicable environmental
protection regulations
l Check the silencer regularly and clean it if necessary
