5.3. Commissioning
The chapter contains all the important instructions for the
operating staff for secure commissioning and operation of
the machine. The following information must be retained
and checked:
•
Type of installation
•
Type of operation
•
Minimum water coverage / Max. immersion depth
Also inspect after it has been stationary for a long peri-
od of time and remove any faults that you find.
To avoid material damage and personal injury when oper-
ating the machine, the following points must be followed:
•
The machine must only be commissioned by qualified
and trained staff following the safety instructions.
•
The entire staff that work on the machine must have
received, read and understood the operating manual.
•
This machine is only suitable for use under the oper-
ating conditions specified.
5.4. Preparatory Work
The machine has been designed and assembled accord-
ing to the state of the art, so that it works reliably for a
long time under normal operating conditions. However, a
prerequisite for this is that you follow all the requirements
and instructions.
Please check the following points:
•
Cable guidance – no loops, slightly taught
•
Check the temperature of the conveying medium and
immersion depth
•
If a hose is used on the discharge side, this is to be
rinsed through with clean water before it is used, so
that there are no deposits or blockages
•
For a wet setup, the pump sump is to be cleaned
•
The pipework system on the discharge side and suc-
tion side is to be cleaned, and all gate valves are to
be opened.
•
The pump housing must be ventilated, i.e. it must be
completely filled with the medium and it must not
contain any more air. The ventilation may be done
by suitable ventilation equipment in the system or,
if present, by bleeder screws on the pressure joint.
•
Check the accessories, pipework system and the at-
tachment device for correct, firm seating.
5.5. Electrical System
When laying and selecting the electrical lines and when
connecting the motor, the relevant local and VDE regula-
tions are to be followed. The motor must be protected by
a motor overload switch.
Danger due to electricity!
There is danger of death due to improper handling
of electricity!
5.6. Direction of Rotation
For 1Ph motors, checking the direction of rotation is not
necessary, as it can always run with the correct direction
of rotation.
5.7. Type of Activation
Types of Activation with Plug
Plug the plug in the socket provided for this purpose.
Pump runs directly, if the sensor is triggered.
5.7.1. After Activating
The rated current is briefly exceeded during the starting
process. After this process has finished, the operating
current should no longer exceed the rated current. If the
motor does not start immediately after switching on, it
must be shut down immediately. Before switching on
again, the pauses must be maintained according to the
technical data. If there is a new fault, the machine must
be shut down again immediately. A new activation pro-
cess must only be started after troubleshooting.
The following points should be checked:
•
Switching frequency and pauses (see Technical Data)
•
Air introduction on admission side, a baffle plate may
have to be attached
•
Minimum water covering, level control, protection
against dry running
•
Quiet running
•
Check for leaks, take any necessary steps according
to the “Maintenance” chapter
6. Maintenance
6.1. General
The pump as well as the entire system must be inspec-
ted and maintained at regular intervals. The interval of
the maintenance is determined by the manufacturer and
applies for the general conditions of use. The manufac-
turer must be contacted in the event of aggressive and/
or abrasive pumped mediums, since the interval could be
shortened 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 cleaning
work on the machinery and the system must be car-
ried out with due diligence, at a safe working place
and by trained qualified personnel. The required pro-
tective 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.
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 jeopardize your life!
