l
Switch on the main disconnect switch, then release the emergency
stop button. Restart the pump by pressing on Start button on the
remote control. If the pump does not start, press on emergency
stop button, switch off and padlock the main disconnect switch,
switch off the customer’s power supply and put the label
“maintenance processing”. Call the BUSCH Semicon service team
in charge of the maintenance of the pumps.
l
If the external thermal protection B1 is engaged, check that the
water flow shows 2l/min on the flowmeter. If not, set the water
flow at 1,5 l/min according to the instruction (see chapter
“Checking the cooling liquid flow”). Check the wiring system of
the thermal protection by opening the side face (Type 3 of
electrical work). Wait a few hours for the cooling of the protection,
then press on Start button to restart the pump.

Position of the pump gravity center
l
The gravity center of the BC 0200 F pump is determined according
to the drawing
Installation of the vacuum pump in a
seismic zone
l
Convey the pump to its final location with a pallet truck before
removing it from its support
l
Unscrew the fixing screws of the pump on the transport pallet and
remove the machine from its support with an appropriate lifting
system by using the lifting brackets made for this purpose
l
Check that the wheels no longer touch the ground
CAUTION
The vacuum pump is fixed to the ground with four M10 screws, one
screw per bracket. The fixing screw must stand a 1200 N tensible
force (per bracket).
The final user must adapt the type of screws depending on the
ground material.
