Every 6 Months:
●
Make sure that the housing is free from dust and dirt, clean if nec-
essary
●
Make sure that the vacuum pump is shut down and locked against
inadvertent start up
Note : Any kind of deposit on the vacuum pump compromises the ex-
plosion safety of the vacuum pump.
●
Clean the fan cowlings, fan wheels, the ventilation grilles and cool-
ing fins
WARNING
_ad
The proper assembly of flame arrestors is essential for their safe
function.
Risk of explosion in case of faulty assembly!
Flame arrestors must only be serviced by personnel that have re-
ceived specific training for this purpose either by Busch or by the
manufacturer of the flame arrestors.
●
Service the flame arrestors (i) (k) (d) - in case of discolouration or
deformation consult Busch or the manufacturer of the flame
arrestor in any case
●
Check the electrical connection
●
Make sure that the earth cable (cable between earth connection of
the vacuum pump and earth point) is undamaged (resistance
check)
Every Year:
●
Make sure that the vacuum pump is shut down and locked against
inadvertent start up
●
Replace the exhaust filter (
Ú
page 12: Exhaust Filter)
In case an inlet air filter is installed:

Every 16000 Operating Hours, At the Latest after
4 Years:
●
Have a major overhaul on the vacuum pump (Busch service)
Checking the Oil
Checking the Level
●
Make sure that the vacuum pump is shut down and the oil has col-
lected at the bottom of the oil separator (j)
●
Read the level on the sight glass (p)
In case the level has dropped underneath the MIN-marking:
◆
Top up oil (
Ú
page 10: Topping up Oil)
In case the level exceeds the MAX-marking:
◆
Excessive dilution with condensates - change the oil and check
the process
◆
If appropriate retrofit a gas ballast (Busch Service) and observe
the chapter Conveying Condensable Vapours (
Ú
page 9)
In case the level exceeds the MAX-marking despite proper use of the
gas ballast:
◆
Clean the sinter metal filter (compressed air)
Topping up Oil
Note : Under normal conditions there should be no need to top up oil
during the recommended oil change intervals. A significant level drop
indicates a malfunction (
Ú
page 14: Troubleshooting).
Note : During operation the exhaust filter gets saturated with oil. It is
therefore normal that the oil level will drop slightly after replacement
of the exhaust filter.
CAUTION
_a
Filling oil through the suction connection (f) will result in breakage
of the vanes (i) and destruction of the vacuum pump.
Oil may be filled through the filling port (g, o) only.
CAUTION
_a
During operation the oil separator is filled with hot, pressurised oil
mist.
Risk of injury from hot oil mist with open filling port.
Risk of injury if a loosely inserted filling plug (g, o) is ejected.
Remove the filling plug (g, o) only if the vacuum pump is stopped.
The vacuum pump must only be operated with the filling plug (g, o)
firmly inserted.
●
Make sure that the vacuum pump is shut down and locked against
inadvertent start up
●
Remove the filling plug (g, o)
●
Top up oil until the level reaches the middle of the sight glass (p)
●
Make sure that the seal ring is inserted into the filling plug (g, o)
and undamaged, replace if necessary
●
Firmly reinsert the filling plug (g, o) together with the seal ring
Checking the Colour of the Oil
Note : The oil should be light, either transparent, a little foamy or a little
tarnished. A milky discolouration that does not vanish after sedation of
the oil indicates contamination with foreign material. Oil that is either
contaminated with foreign material or burnt must be changed
(
Ú
page 11: Oil Change).
