5. Installation

5.1 Preparations
A correct and proper montage is pivotal for the failure-free operation of the pump station.
-
For this reason, the following points must be observed:
The place of installation should be a well ventilated, dry and rust-free room.
-
The place of installation must be large enough. The ceiling heights should be approx. 2 to
-
2.5 m. According to DIN 1986 part 3, the following applies: „...All parts of the unit
...(and)...all control elements...must always be safely accessible and easy to operate.
...These parts of the unit must not be obstructed by stored parts, furniture, cover panels or
several..."
The foundation of the installation room must be constructed for the possible loads
-
depending on the dimensions of the unit.
In rooms mostly located lower, ground and leakage water is accumulated. Due to this fact,
-
a small chamber should be located in a corner of the room, where the liquids will be
accumulated and can be disposed of using a cellar drainage pump.
A ceiling hook below the place of installation of the pump station facilitates the assembly
-
as well as possible maintenance and repair works on the pump.
Before starting the assembly, all structural and cable dimensions should be controlled and
-
compared with the dimensions of the unit. In doing to, it is important to ensure that the
continuously declining inlet pipe is located not deeper than the inlet height of the collecting
tank.

5.2 Assembly

During assembly, it is essential to ensure a zero-potential and tight installation of the pipelines
and valves.

5.2.1 Placement

The sewage ejection units of the type series Conpactboy will be adjusted on place of
installation to existing pipelines. Here, it is placed in an exactly vertical position and fixed onto
the floor using the included fixation screws.
DIN 19 760 part 1:"...The excrements pump station must be designed in such a way that the
fixing devices prevent torsion and buoying upwards..."

5.2.2 Inlet

The inlet pipe(s) will be connected to the included inlet bend and/or to the lateral inlets. It must
be constantly declining. Inclining passages within the inlet are forbidden. The necessary inlets
must be opened on the provided cutting edge using a saw. The inlet on the back of the Duplex
unit has to be opened using a hole circle saw or knife. Do not use a hammer!
Important:
When using the minimum inlet height of 180 mm it must be ensured, that the level control is
adjusted in such a way, that the water level of the tank in normal operation slightly increases
the lower edge up to a maximum filling of ½ of the inlet pipe before the pump switches on. In
case of inlet pipes, dirt depositions in the inlet line are not excluded in this area and in extreme
cases, the line could be blocked. This applies in particular to the lateral DN 50, due to the fact
that they are entirely filled in every case before the pump is switched on. A connected
drainage object must have its inlet minimum 180 mm above the installation level of the pump
station!
