Malfunctions: Cause And Troubleshooting - SFA SANISUB ZPK 30 Notice De Service / Montage

5. INSTALLATION
Prior to commissioning, check the pump
for possible external damages (e.g.
transport damages) in order to prevent
accidents with electrical current.
If the pump shall be inserted into a pit or a duct,
its dimensions must allow the float switch to move
freely.
When the water level rises with the float floating
to the top, so the pump will turn on and pump off
the water until such a low water level has been
achieved that the float turns off the pump again.
The heights required by the float to start and stop
the pump can be changed by moving the float
cable through its fixing eyelet.
The inlet screen must not be clogged by mud and/
or fibrous media.
Even an automatically operating device,
such as a submersible pump, must not be
operated for a long period of time without
supervision.
Note: Place the pump in an initial water level of
at least 120 mm (SANISUB ZPK 30), or 200 mm
(SANISUB ZPK 40) to allow priming.
