To compensate for the height difference between the top edge of
the pump chamber and the surface level, a plastic pump chamber
extension can be installed or concrete adjusting rings can be used.
NOTE:
It is not possible to use a pump chamber extension for the pump
chamber "Port 600...E".

The plastic pump chamber extension can be used to extend the
pump chamber by 200 to 500 mm. The pump chamber extension
is made of PE material and must be ordered as an accessory (not
available for Port 600...E).
1.
Determine the required extension for the surface level.
Take into account the height of the pump cover.
2.
The required dimension is defined by the selected groove at the
taper of the extension.
Select the appropriate groove using the following table:

Grooves 1, 2 and 10 may not be used.
3.
Insert the O-ring supplied in the selected groove in the extension.
4.
Coat the O-ring and the inside of the taper on the pump chamber
with lubricant (washing-up liquid or even water in an emergency).
5.
Slide the pump chamber extension into the pump chamber until the
O-ring wedges securely in the cone in the taper.
Do not push the O-ring beyond the cone. Make sure that the
O-ring slides cleanly into the taper, does not twist and is not
pushed out of the groove. If necessary, push the O-ring further by
hand when fitting the extension.
