Notes
•
Installation and start-up must only be undertaken
by trained persons. Damage due to improper han-
dling is not included in the guarantee terms.
•
The machine is delivered in fully assembled condi-
tion. It must not have suffered damage in transit.
•
Please make certain that the rotor shaft can be
rotated by hand. If this is not the case, inform our
service staff.
•
Lift the machine using only the securely installed
eye bolts.
For use in a potentially explosive atmos-
phere,all parts of the equipment must satisfy
the requirements for the zone in which they
are used.
Note that it may be necessary to provide
equipotential bonding between the equip-
ment and the truck. The safe operation of the
vacuum pump in a potentially explosive at-
mosphere requires that all safety instructions
in our operating instructions and comple-
mentary instructions are strictly observed.
