If necessary, clean the seal contour of the seal and of the hood, and lightly lubricate it using a recom-
mended silicone grease (e.g. Paraliq GTE 703).
caution:
do not use any petroleum-based or synthetic lubricants (except for silicone grease)!

Put the plastic hood on the lower part such that the inner lugs are positioned over the fastening grooves and
→
the external sealing lugs are positioned almost over each other. Press the hood completely over the seal of the
lower part.
Turn the hood by approx. 1.5 cm clockwise (meaning until the sealing lugs are positioned over each other).

Potentially, apply more sealing and plastic self-cutting screws.
