4 . INSTALLATION
DANGER
Work by unqualified personnel .
Risk of injury. Risk of damage to the station.
 Installation, mounting, operation and maintenance may be carried out by a specialist company only.
 Les directives et les règles de sécurité doivent être respectées.
4 . 1 PRODUCING THE EXCAVATION PIT
The excavation pit must be created with due regard to the regulations of the civil engineering (slope angle, possibly shor-
ing up the tank etc.).
4 .2 INSERTING THE SHAFT
Before inserting the tank, the excavation pit has to be backfilled with approx. 30 cm of crushed rock and condensed with 5
cm grit so that a horizontal supporting surface comes into being. Then, the PE tank has to be inserted into the excavation
pit and aligned. Now fill up approx. 30 cm filling sand and condense.
IMPORTANT
Check if the tank still stands level.
4 .3 CONNECTING THE SHAFT
4 .3 .1 Inlet
An inlet sleeve DN 150 with lip seal is available in the tank. The inlet line (pipe DN 150) is plugged approx. 1 cm into the
inlet sleeve. Beforehand, a lubricant or grease has to be applied on the inside of the seal. The max. deviation of the axis of
the inlet must not exceed 3°. Further inlets are possible as an option.
4 .3 .2 Pressure line
The pressure pipe line ends approx. 180 mm outside the tank with a pipe socket PE HD 63x5.8. PE HD pipe 63x5.8 should
be installed as pressure line. Connection to the pipe socket which is available at the tank can take place by means of a
commercial compression fitting, for example.
4 .3 .3 Ventilation / cable routing
2 sleeves with lip seal DN 100 are available for ventilation / cable entry. The ventilation pipe (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.
4 .3 .4 Electrical connection
DANGER
Electrical connection work performed by an unqualified individual .
Risk of death by electric shock!
 The electrical connection must be performed by a qualified and licensed electrician.
 The electrical installation must meet the current standards in the country.
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.
IMPORTANT
• The shut-down point and the run-on time have to be adjusted in such a way that the pumping process is com-
pleted prior to the pump housing emerging, but the pitot tube has already completely emerged.
• The pneumatic hose has to be guided rising steadily and without loops to the switchgear. The maximum length
should not exceed 20 m.
4 .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.
