5.10.1. After Start-Up

The rated current is briefly exceeded during the start-up
procedure. Once this process has ended, the operating
current should no longer exceed the rated current.
If the motor does not start immediately after the machine
is switched on, it must be switched off immediately. The
start pauses specified in the technical data must be ad-
hered to before starting up again. If the fault recurs, the
machine must be switched off again immediately. The ma-
chine may only be started again once the fault has been
rectified.
The following items should be monitored:
• Operating voltage (permissible deviation +/- 5% of
the rated voltage)
• Frequency (permissible deviation -2% of the rated fre-
quency)
• Current consumption (permissible deviation between
phases is a maximum of 5%)
• Voltage difference between the individual phases
(max. 1%)
• Starts and stops per hour (see technical data)
• Air entry in the infeed, a deflector plate should be fit-
ted if necessary
• Minimum water immersion level, level control unit,
dry-run protection
• Smooth running
• Check for leaks, if need be, follow the necessary
steps as set out in "Maintenance"

6. Maintenance

6.1. General

The pump as well as the entire system must be inspect-
ed and maintained at regular intervals. The interval of the
maintenance is determined by the manufacturer and ap-
plies for the general conditions of use. The manufacturer
must be contacted in the event of aggressive and/or abra-
sive pumped mediums, since the interval could be short-
ened in these cases.
The following points must be noted:
• The operating instructions must be available to the
maintenance personnel and must be followed. Only
maintenance work and measures listed here must be
carried out.
• All maintenance work, inspection work and clean-
ing work on the machinery and the system must be
carried out with due diligence, at a safe working
place and by trained qualified personnel. The required
protective gear must be worn. The machinery must
be disconnected from the power supply for all work.
Unintentional start must be prevented. Furthermore
the respective protective measures according to the
Employers' Liability Association regulations, BGV/the
Statutory Accident insurance, GUV must be complied
with when working in basins and/or containers.
• For weights over 50 kg, technically flawless and
licensed auxiliary lifting devices must be used for
lifting and lowering the machine.
Ensure that sling gear, ropes and the safety equipment
of the hand winch are technically sound. The work
must only be started when the auxiliary hoisting gear
is technically in order. Failure to carry out these checks
may jeopardise your life!
• Electric works on the machinery and the system
must be carried out by a specialist. For ex-approved
machines, you must also observe the „Ex protection"
section in the annex!
• If easily inflammable dissolvers and cleaning materi-
als are used, open fire, open light and smoking are
prohibited.
• Machines which circulate hazardous materials or
come into contact with these must be decontaminat-
ed. It is also important to ensure that no hazardous
gases form or are present.
• Ensure that the required tools and materials are read-
ily available. Tidiness and cleanness ensure safe and
proper work on the machinery. Remove used clean-
ing materials and tools from the machinery after the
work has been carried out. Keep all materials and
tools in a dedicated place.
• Service media (such as for example oils, lubricants,
etc.) must be captured in a suitable container and
must be disposed of according to the regulation
75/439/EEC and writ §§5a, 5b AbfG, Waste Avoid-
ance and Management Act). Respective protective
clothing must be worn when carrying out clean-
ing work and maintenance work. This must be dis-
posed of according to waste catalogue TA 524 02
and EC directive 91/689/EEC. Only lubricants rec-
ommended by the manufacturer must be used.
