4. First fit the inlet port. Fit the sealing ring. Before
mounting, check that the sealing ring (A) is not
deformed or damaged and replace it if
necessary.
5. Before fitting check that the hose clamp is not
damaged and replace it if necessary. Slide the
flange bracket (B) and the hose clamp (C) over
the hose together. Align the holes in the flange
bracket with the ones at the front of the port.
Position the four retaining bolts (A) and tighten
them until they are approx. 5 mm from the port,
so that the gap between the flange bracket and
the port remains.
6. Slide insert (B) in the flange (A) and press the
insert in the hose. If necessary lubricate the
insert with Bredel Genuine Hose Lubricant in
order to simplify mounting. Make sure that the
holes in flange (A) are aligned with the holes in
flange bracket (C). Check that the insert is in
the correct place. If the insert is not positioned
correctly the product to be pumped may leak or
the lubricant may leak.
7. Turn the rotor in such a way that the hose (A) is
pressed firmly against the flange surface (B).
