Pressure Line; Installation - SFA SANICUBIC SC Série Mode D'emploi

- The installation location should be a well-ventilated, dry and frost-free room.
- The installation site must be amply dimensioned. The room height should be approx. 2 to 2.5 m.
According to DIN 1986, Part 3, the following applies: "All plant components... (and)... all operating
elements... must be safely accessible at any time and possible to be operated without any problems.
...These plant components must not be obstructed by stored goods, furniture, coverings or similar
items...".
- The foundation of the installation room must be designed to meet potentially occurring loads depending
on the size of the plant.
- In rooms which often lie lower, ground water or seepage water often accumulates. That is why in
one corner of the room, there should be a small tank, where these liquids can accumulate and can be
disposed of using a cellar drainage pump.
- A ceiling hook above the installation site of the lifting unit facilitates the assembly as well as potential
maintenance and repair work on the pump.
- Before starting installation, all structural and line measurements should be checked and compared
with the dimensions of the unit. While doing so, it has to be particularly made sure that the constantly
declining inlet line does not lie lower than the inlet height of the collecting tank.
5.2 Assembly
During installation, it is absolutely necessary to ensure a stress-free and tight installation of the pipelines
and fittings.
5.2.1 Setting up
The sewage lifting units of the series SANICUBIC SC are aligned a the installation site according to potentially
®
existing pipelines. Here, they are set up exactly horizontal.
"The sewage lifting unit has to be secured by means of suitable attachment equipment on site against twisting
and buoyant floating!"
5.2.2 Inlet
The inlet line is connected to the flange DN 150. It must always be installed on a downhill incline. Uphill
sections in the inlet are not permitted.

5.2.3 Pressure line

Installation of a check valve in the pressure line of the lifting unit must always be installed:
DIN 19 760, Part 3: "Following interruption of the pump delivery, a backflow preventer must automatically
impede the backflow of the waste water from the pressure line. When the pump starts delivering, the backflow
preventer must automatically open..."
It is recommended to install a shut-off valve behind the check valve in order to facilitate cleaning or potential
replacement of the check valve.
The pressure line must be installed constantly rising and without unnecessary leaps in an arc beyond the
flood level and then constantly descending toward the sewer connections. Pipelines and fittings must, where
necessary, supported using pipe clamps or brackets.
5.2.4 Ventilation
The tank ventilation (flange DN 100) is installed either directly to the venting line of the building or guided
separately above the roof.
5.2.5 Electrical Connection
Safety precautions :
• All electrical systems used must comply with the standard IEC 364 / VDE 0100, that is sockets, for
example, must have earth terminals.
• The electrical connection may be carried out by an electrically qualified person! The pertinent VDE
regulation 0100 must be observed!
• The electrical network, to which the plant is connected, must have been fitted with a highly sensitive
FI protected switch IA <30 mA before the control, or to prevent a failure of the control when the FI
protected switch trips, one FI protected switch per pump has to be installed between the control and
