Installation

Make sure that no items like welding beads, screws, nuts, washers, small 
pieces of wire, for example, enter through the inlet into the pump. Carefully 
handle the sealing surfaces and keep them clean.

We recommend that two fitters fit the adapter.

The Roots vacuum pump must only be fitted as depicted. Other orientations 
are 

not

 allowed as otherwise stability is endangered.
