5 Mounting
5.1 Preparing mounting
If the filling line is longer than 20 m, do not determine the adjustment
dimension X on the basis of the adjustment tables, but take into account the
special conditions.
The adjustment dimensions X specified take into a account a manhole socket
height of 100 mm for tanks according to EN 12285-1/12285-2/DIN 6618 and
60 mm for tanks according to DIN 6619 as well as a total thickness of the
manhole cover including the seal of 20 mm.
• In the case of a different height of the manhole, correct the adjustment
dimension X according to the deviation.
• Install the level sensor vertically. It must always be installed in the tank
from the manhole cover or the tank top.
5.2 Mounting the product
In the case of underground tanks, the distance between the upper edge of
the connection fitting and the lower edge of the manhole cover must be at
least 20 mm and no more than 300 mm.
1. Determine the adjustment dimension X and the check dimension Y as per
chapter "Determining adjustment dimension X".
2. Loosen the locking screws at the screw fitting.
3. Set the adjustment dimension X between the reference edge of the man-
hole cover or the screw fitting (take into account the thickness of the seal)
and the marking groove at the protective sleeve.
4. Tighten the locking screws.
5. Screw the screw fitting with the product into the tank socket (with seal).
6. Check correct installation of the product via the check dimension Y.
7. Mount the fitting for wall mounting (type -Wa) directly next to the filling
connection of the tank.
The fitting can be mounted on a plane wall with dowels or next to the filling
opening using a console.
- A clip is used to mount the console to the filling pipe.
- As an alternative, the connection can be made with a GWG filler cap.
