Commissioning
m
The safety hints in the previous sections must be observed!
g
In explosive zones care must be taken that during switching on and operation of the pumps the pump
section is filled with water (dry running) or alternatively is submerged or under water (wet installation).
Ensure in this case that the minimum submergence given in the data sheet is observed. Other types
of operation e.g. snore operation or dry running are not allowed.
Before commissioning the unit should be checked and a functional test carried out. Particular attention should
be paid to the following:
Have the electrical connections been carried out in accordance with regulations?
Have the thermal sensors been connected?
Is the seal monitoring device (where fitted) correctly installed?
Is the motor overload switch correctly set?
Have the power and control circuit cables been correctly fitted?
Was the sump cleaned out?
Have the inflow and outflows of the pump station been cleaned and checked?
Is the direction of rotation correct - even if run via an emergency generator?
Are the level controls functioning correctly?
Are the required gates valves (where fitted) open?
Do the non-return valves (where fitted) function easily?
Have the hydraulics been vented in the case of dry installed pumps?

Maintenance
c
Before commencing any maintenance work the unit should be completely disconnected from the
mains by a qualified person and care should be taken that it cannot be inadvertently switched back on.
m
When carrying out any repair or maintenance work, the safety regulations covering work in enclosed
areas of sewage installations as well as good general technical pratices should be followed.
NOTE
The maintenance hints given here are not designed for “do-it-yourself” repairs as
special technical knowledge is required.
NOTE
A maintenance contract with our works service department will guarantee you the
best technical service under all circumstances.
6.1
General maintenance hints
ABS submersible pumps are reliable quality products each being subjected to careful final inspection.
Lubricated-for-life ball bearings together with monitoring devices ensure optimum pump reliability provided that
the pump has been connected and operated in accordance with the operating instructions.
Should, nevertheless, a malfunction occur, do not improvise but ask your ABS customer service department for
assistance.
This applies particularly if the pump is continually switched off by the current overload in the control panel, by
the thermal sensors of the thermo-control system or by the seal monitoring system (DI).
Regular inspection and care is recommended to ensure a long service life.
