MAINTENANCE AND REPAIR

7.2. Decommissioning for maintenance work or
storage
The system must be switched off and the pump
must be disconnected from the mains by an
electrician and secured against being switched
on again without permission. Pumps with plugs
must be unplugged (do not pull the cable!). Work
on removal, maintenance and storage can then
commence.
BEWARE of poisonous substances!
Pumps that pump liquids hazardous to health
must always be decontaminated before un-
dertaking any other work! Otherwise, there
is a risk of fatal injury! Wear the necessary
physical protection equipment!
BEWARE of burns!
The housing parts can heat up to well above
40 °C. There is a risk of burns! After switch-
ing it off, let the pump cool down to ambient
temperature.
7.2.1. Removal
Portable wet well installation
Pumps in portable wet well installation can be
lifted out of the pit once they have been discon-
nected from the mains and the pressure pipe has
been drained. It may be necessary to dismantle
the hose first. It may be necessary to use a suit-
able lifting device.
Stationary wet well installation
Pumps in stationary wet well installations with
a suspension unit are raised out of the pump
chamber using the appropriate lifting equipment.
During lifting, always hold the power supply cable
slightly taut to prevent it being damaged.
The operating space does not have to be emptied
especially for this purpose. The gate valves in the
inlet and in the pressure pipeline must be closed
to prevent the operating space overflowing or the
pressure pipeline being emptied, respectively.
Stationary dry well installation
For pumps in stationary dry well installation, the
suction and pressure-side gate valves have to be
closed before removal. Note that the fluid in the
hydraulics housing will escape during removal.
Suitable collector tanks should be positioned to
collect all of the escaping fluid.
After undoing the screwed connections on the
suction and pressure connections, the pump can
be removed using suitable lifting equipment. The
operating space must be cleaned thoroughly after
the pump is removed and any drips must be wiped
up.

7.3. Return delivery/storage

For shipping, the parts must be packed in tear-
proof plastic bags of sufficient size in such a
manner that they are tightly sealed and leak-
proof.
