3 Transport/Temporary Storage/Disposal
3.1 Checking the condition upon delivery
1. On transfer of goods, check each packaging unit for damage.
2. In the event of in-transit damage, assess the exact damage, document it and
notify KSB or the supplying dealer (as applicable) and the insurer about the
damage in writing immediately.
3.2 Transport
DANGER
System falling off the pallet
Risk of injury by falling system!
▷Always transport the system in vertical position (with the cover on top).
▷Never suspend the system by its power cable.

1 Collecting tank 2 Nozzles for inlet or venting
3 Float switch 4 Ball check valve
5 Discharge line 6 Submersible motor pump
7 Cable entry for power cable 8 Drainage nozzles

The pump station consists of a stable collecting tank (1) with integrated submersible
motor pump (6), an inlet nozzle (2) and a vent nozzle (2) (8 options available for
selection) as well as a discharge line (5).
The fluid handled flows into the pump station through the inlet nozzle (2) and is
collected in a gas-, odour- and water-tight tank (1) made of polyethylene. As soon as
the float switch (3) detects a defined fill level, the submersible motor pump (6) is
started up automatically. The fluid handled is pumped off through the discharge line
to a level above the flood level and into the public sewer. As soon as the float switch
(3) detects a defined minimum fill level, the submersible motor pump (6) is stopped
automatically.

11 Float switch for alarm
The pump station consists of a stable collecting tank (1) with two integrated
submersible motor pumps (6), a horizontal (2) or vertical (3) inlet nozzle, a horizontal
(2) or vertical (3) vent nozzle (12 options available for selection) as well as two
discharge lines (5).
The fluid handled flows into the pump station through the inlet nozzle (2) or (3) and
is collected in a gas-, odour- and water-tight tank (1) made of polyethylene. As soon
as the float switch (9) detects a defined fill level, the first submersible motor pump
(6) is started up automatically. The fluid handled is pumped off through the
discharge line to a level above the flood level and into the public sewer. If the float
switch (10) detects a rising fill level while one pump is in operation, the second
submersible motor pump (6) is started up automatically. As soon as the float switch
(9) detects a defined minimum fill level, both submersible motor pumps (6) are
stopped automatically. The alarm float switch (11) needs to be connected to an alarm
switchgear for acoustic or visual alarm (optional alarm switchgear can be supplied by
KSB).

NOTE
Other operating manuals that describe components of this lifting unit must also be
observed.
Any transport locks that might have been provided have to be removed prior to
assembly and installation.
NOTE
Lifting units should not be installed next to sleeping or living quarters.
NOTE
In countries which require the use of explosion-proof pumps for handling water
containing faeces, this system must not be used for this specific fluid.
5.3 Preparing the collecting tank
5.3.1 Inlet nozzles and vent nozzles
The collecting tanks are fitted with a selection of inlet and vent nozzles of various
sizes and alignments. (⇨ Section 9.2 Page 51)
DANGER
No vent line fitted
Explosion hazard from gas accumulation!
▷Always make sure that a vent line is fitted.
Evamatic-Box N 200 l Evamatic-Box N 500 l
1. Saw off the end of the selected nozzles, making sure that the nozzle passage is
completely open.
To facilitate fitting the connections always leave some of the chamfered
protrusion.
5.3.2 Discharge-side connection
CAUTION
Incorrect openings in the collecting tank
Collecting tank cannot be used!
▷Always provide openings in the correct places, at the correct distance, with the
correct diameter.
