Orientation of the filter housing in the Maxi tank dome
The filter housing is placed in the tank dome so that the pipes can be laid through the openings of the Maxi
tank dome. The side openings in the 3 and 9 o'clock position are used for the inlet and fastening. If an
emergency overflow is to be connected, the 12 o'clock position can be used. The 6 o'clock position cannot
be used because the opening is lower.

Laying connections
The inlet (1) (HT pipe 250 mm DN 110) is fitted at the 3 o'clock or 9 o'clock position on the tank dome. The
pipe is inserted (narrower end first) from the inside to the outside and the sleeve is connected to the filter
housing.
To secure the fixing pipe (250 mm, DN 110) (2), use a double sleeve. The fixing pipe is inserted from outside
to inside, narrower end first. The pipe end and the connection of the filter housing must lie directly against
each other before the double sleeve is tightened.
The pipe and the double sleeve for the emergency overflow are not included in the scope of supply.
