CAM LOCKING MECHANISM OPTION
• Take the cover and drill a Ø 21 mm hole in
the centre of the hollow cylindrical shape
provided for the locking mechanism
• Insert the upper part of the barrel (1) in the
hole which has been drilled (the triangular
shape of the barrel should be outside the
cover) as indicated in the diagram below.
• Next thread the nut (2) over the barrel
(inside of the cover)
• Then place the locking lug (3) over the
square form of the barrel and insert the
screw (4) to keep the lug in place.
• Using the spanner (5) release the locking
device so that the lug (3) does not project
outside the cover. Screw the cover over
your lift station, then lock the cover with the
spanner. Remove the spanner and position
the cap supplied over the cover in order to
prevent clogging with dirt.
