Insert the pre-filter drain pipe into the double branch for corners.
Tighten the compression fitting by hand.
Secure the pre-filter to the mount using self-tapping screws
(accessories bag).
The inlet of the pre-filter can be rotated and therefore adapted to on-
site conditions.
After the pre-filter has been aligned, it has to be sealed.
