4.5 Ventilation
According to the recommendations of EN 12050-1, pumping stations 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 (SANIFOS
®
110P, 280 and 610) or
Ø ext. 100 (SANIFOS
®
1300) vertically to the vent hole using the flexible
sleeve.
On SANIFOS
®
280 and SANIFOS
®
610: 1 ventilation hole is available.
On SANIFOS
®
1300: 4 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 chamber to facilitate assembly of the fittings.
Ventilation should be at a distance of approximately 50 cm from the
tank cover.
WARNING
Insufficient ventilation. Risk that the pumping station will not work!
