Monitoring devices
The pump chamber is used to collect sewage. In the event of a fault in the system, the
sewage can become backed up to the inlet. In serious cases, the pump chamber can
overflow.
The installation of a high water alarm is recommended to ensure operational reliability.
For increased safety, the high water alarm should be reported via GSM or fieldbus.
2.5
Explosive atmosphere in the col-
lection reservoir
Sewage containing faeces can lead to gas accumulations in the tank. These gas accu-
mulations can escape into the operating space and create an explosive atmosphere as a
result of incorrect installation or maintenance work. This atmosphere can ignite and
lead to an explosion. In order to prevent an explosive atmosphere, observe the follow-
ing points:
ƒ
Tank must be undamaged (no cracks, leaks, porous material)! Take any defective
lifting units out of operation.
ƒ
Ensure all connections for the inlet, pressure pipe and aeration and venting are
sealed tightly and in accordance with regulations!

When opening the tank (e.g. during maintenance work), ensure appropriate ex-
change of air!
