Electrical Connection - SFA SANIFOS 1600 Manual De Instrucciones

(pipe DN 100) is inserted into the sleeve (see inlet). To avoid any bad odour, we recommend to
guide the venting line over the roof. The cable empty pipe (pipe DN 100) is inserted into the other
sleeve and guided further up to the switchgear. The pipe has to be closed at the outlet in the control
cabinet or building (e.g. by a blind cover with cable glands). If a pipe connection is required, so
it has to be closed using a commercial blind cover.

Electrical connection

The pump cable and the pneumatic hose/ float switch cables are guided in the cable empty pipe
toward the switchgear.
The operating instructions of the pump and the circuit diagram apply for the electrical connection.
The shut-down point and the run-on time have to be adjusted in such a
way that the pumping process is completed prior to the pump housing
emerging, but the pitot tube has already completely emerged. The pneu-
matic hose has to be guided rising steadily and without loops to the swit-
chgear. The maximum length should not exceed 20 m.
5.4 Filling the excavation pit
Prior to filling the excavation pit, the lip seal for the top piece has to be inserted into the tank and
the top piece be inserted and adjusted using the BEGU tank cover of the ground elevation
Please note that the pressure test of the pressure line must not be carried
out against the shut-off valve.
When all lines have been connected and checked for tightness, the
excavation pit can be filled.
To fill the excavation pit, filling sand or gravelly sand has to be used in conformity with the civil
engineering/relevant regulations.
Use gravelly sand only up to a grain size of 32 mm, provided that the ex-
cavation ground does not correspond to the particle size group 0 to max.
32 mm.
Cohesive soil, rubble, rock and sharp-edged grain must not be used!
The filling material has to be introduced in layer thicknesses of max. 30 cm and be equally
condensed. In the event of a lowering of groundwater level of the excavation pit, condensation of
the filling material can take place by covering with mud and by adding water with simultaneous
operation of the draw-down device.
Use friable filling material!
To ensure buoyance safety with the soil type of clay, the tank must be filled with sand, clay or
concrete from outside. In order to exclude deformation of the PE tank, high filling from one side
must be avoided by all means.
