5.3. Use of chains

Chains are used to lower/lift a pump into/out of the me-
chanical room. They are not designed for securing a float-
ing pump.
For use according the instructions follow these steps:
• Fix one end of the chain to the provided eyelet/the
handle of the pump.
• Fix the other end on the lifting device.
• Tighten the chain and lift the pump slowly and in a
controlled manner.
• Swing the pump subsequently over the mechanical
room and lower it carefully.
• Lower the pump as far as the operation point and en-
sure a steady position of the pump.
• Remove the chain from the lifting device and safe-
guard this on the chain guard, which is at the upper
edge of the mechanical room. This ensures that the
chain cannot fall into the mechanical room and does
not pose danger to anyone.
Please see the following images for this purpose.

5.4. Commissioning

This chapter contains all important instructions for oper-
ating personnel for safe commissioning and operation of
the machinery. The following must be complied with and
checked:
• Type of installation
• Operation mode
• Minimal submersion in water / maximum submersion
depth
After a longer downtime these points must also be
checked and detected defaults must be repaired!
The operation and maintenance manual must always
be kept with the machinery, or in a dedicated place
where it is accessible for the entire operating person-
nel.
The following points must be taken into account to avoid
personal and material damage when troubleshooting ma-
chinery failures:
•
The commissioning of the machinery must only
be carried out by qualified and trained personnel
in compliance with the safety regulations.
• All personnel that is working on the machinery must
have received, read and understood the operating in-
structions.
• Activate all safety equipment and emergency switch-
offs before commissioning.
• Electrotechnical and mechanical settings must only
be carried out by specialists.
• This machinery is only suitable for the use under the
indicated operating conditions.

5.5. Preparatory work

The machinery was constructed and fitted according to
the latest technology, so that it works for a long time and
reliably under normal operating conditions. This requires
however that you comply with all requirements and infor-
mations. Small oil leakages of the floating ring seals on
delivery are not problematic, but they must be removed
before lowering/immersion into the medium.
Please check the following points:
• Cable run - no loops, slightly tightened
• Check temperature of the medium and submersion
depth - see machinery data sheet
• If a tube is used for pressure, this must be rinsed with
clear water so that no deposits lead to obstruction.
• Check accessories, pipework, suspension devices for
firm and correct fitting
• Check available level controls/protection against dry
run

5.6. Electrical system

The respective local and VDE regulations must be com-
plied with when choosing and installing the electrical
leads as well as connecting the motor. The motor must be
protected with a circuit breaker. The motor must be con-
nected according to the wiring diagram. Note the direction
of rotation! In the event of wrong direction of rotation the
machine does not perform as indicated and it can become
damaged under unfavourable circumstances.
Electric shock hazard! Faulty dealing with current
may jeopardize your life! All pumps with free cable
ends must be connected by a qualified electrician.
