According to the recommendations of EN 12050-1, pumping sta-
tions must be ventilated. The pumping station must always be
ventilated so that the tank is always at atmospheric pressure.
The ventilation must be completely free and air must flow in both
directions
(no diaphragm valve fitted).
The vent pipe must not be connected to the vent pipe on the inlet
side of a grease trap.
Connect the ventilation duct Ø ext. 75 vertically to the vent hole
using the flexible sleeve.
On SANIFOS
®
250 and SANIFOS
®
500: 2 ventilation holes are
available.
Carefully cut the end of the selected hole so that the through
section is completely clear.
Leave a part of the chamfer to facilitate assembly of the fittings.
Ventilation should be at a distance of approximately 50 cm from
the tank cover.

its base, at the highest point, is located above the back-flow
level.
