Installation, Operating and Maintenance Instructions (Original Instructions)
ABS Piranha submersible grinder pump S10 - PE125

Mounting and installation
The regulations covering the use of pumps in sewage applications together with all regulations
involving the use of explosion-proof motors should be observed.The cable ducting to the control panel
should be sealed off in a gas-tight manner by the use of a foaming material after the cable and control
circuits have been pulled through. In particular the safety regulations covering work in enclosed areas
in sewage plants should be observed together with general good technical practice.
For the Piranha transportable version, arrange the cable run so that the cables will not be kinked or nipped.
Connect the discharge pipe and cable (see section ”Electrical Connection”). Place the pump on a firm surface
which will prevent it from overturning or burrowing down. The pump can also be bolted down to the base or
suspended slightly by the lifting handle. Hoses, pipes and valves must be sized to suit the pump performance.

Discharge Line
The discharge line must be installed in compliance with the relevant regulations.
DIN 1986/100 and EN 12056 applies in particular to the following:
The discharge line should be fitted with a backwash loop (180° bend) located above the backwash level and
should then flow by gravity into the collection line or sewer.
The discharge line should not be connected to a down pipe.
No other inflows or discharge lines should be connected to this discharge line.
ATTENTION!
The discharge line should be installed so that it is not affected by frost.
The vent line is connected by means of a push-on sleeve to the vertical outlet at the top of the collection tank.
It should be of constant cross-section (min. DN 70) and should have a continuous rise to above roof level.
