4. DESCRIPTION
4.1 General
The effluent lifting units of the SANICUBIC
®
GR production series are single systems that are ready
to plug in and safe against flooding, with collection chambers made of gas- and odour-proof plastic.
They work with vertical cutting unit pumps with automatic pneumatic level control. They are completely
equipped with switch boxes and all necessary switching elements.
4.2 Construction and work method
The effluent falls into the collection chamber of the SANICUBIC
®
GR effluent lifting unit through the
DN 100 (HT pipe) inflow.
The water rises in the back-up pipe screwed onto the top side of the chamber and compresses the air
located in the back-up pipe until the pressure activates the banking up pressure switch in the switch box.
This switches on the pump and conveys the water out of the chamber via the pressure main in the canal
lying above.
The back-kick flaps in the pressure main prevent the return flow of the water from the pressure main into
the chamber.
The switching system is provided with an acoustic alarm which is activated when the pump(s) fail(s) or
when the supply flow is too strong. The motor is automatically switched off at overload (excessive current
consumption or excessive coil temperature).
5. INSTALLATION
5.1 Preparations
A fault-free operation of the lifting unit is not least dependent on a correct and flawless assembly. For
this reason you have to note the following points:
- The set-up site should be a room that is well ventilated, dry and free of frost.
- The set-up site must be sufficient in dimensions. The height of the room should be around 2 to 2.5 m.
According to DIN 1986 (German standard) part 3: "...All system parts...(and)... all operating elements...
have to be accessible at all times and be operable without difficulties. ...These system parts are not to
be blocked by stored commodities, furniture, cladding, casings and so forth..."
- The substructure of the set-up site is to be designed to bear the potential loads, depending on system
size.
- Lower interior spaces tend to collect water from the water table or percolation water. Therefore there
should be a small tank in the corner of the room, where these liquids collect and can be disposed of
with a cellar drainage pump.
- A hook in the ceiling above the set-up site of the lifting unit facilitates assembly and potential maintenance
and repair work on the pump.
- Prior to assembly, all construction and connection measurements should be checked and compared
with the dimensions of the system. Here you should pay special attention that the constantly downward-
inclining supply connection never lies lower than the inflow height of the collection chamber.
5.2 Assembly
Pay urgent heed during assembly to a voltage-free and leak-proof installation of the pipelines and
fittings.
5.2.1 Set-up
The effluent lifting units of the SANICUBIC
®
GR production series are aligned on the set-up site according
to whatever pipelines are provided. It is set up horizontally and fastened to the floor by means of the fixing
screws supplied in delivery.
DIN 19 760 (German standrad) Part 1:"...The excrement lifting installation is to be designed so that distortion
and buoying upwards caused by fixing devices are avoided ..."
