Operating supplies such as oil and lubricants must
be collected in appropriate vessels and properly di-
sposed of (in accordance with the 75/439/EEC direc-
tive and with §§5a, 5b AbfG). Appropriate protective
clothing is to be worn for cleaning and maintenan-
ce jobs. This is to be disposed of in accordance with
waste code TA 524 02 and EC Directive 91/689/EEC.
Only lubricants expressly recommended by the ma-
nufacturer may be used. Oils and lubricants should
not be mixed. Only use genuine parts made by the
manufacturer.
A trial run or functional test of the plant must only be
carried out under the general operating conditions!
6.2. Maintenance dates
Monthly:
•
Checking current consumption and voltage
Semi-annually:
•
Visual inspection of the power supply cable
6.3. Maintenance work
Checking current consumption and voltage
Current consumption and voltage on all 3 phases are to
be checked regularly. In normal operation, these remain
constant. Slight fluctuations depend on the nature of the
conveyed medium. Observing current consumption enab-
les damage and/or malfunctions of blade wheel/propeller,
bearings and/or motor to be detected and resolved at an
early stage. This can largely prevent greater consequential
damage and reduce the risk of a total failure.
Visual inspection of the power supply cable
The power supply cable must be examined for bubbles,
cracks, scratches, abrasions and / or pinching points.
Upon detection of damage, the damaged power supply
cord must be replaced immediately.
The cable may only be replaced by the manufacturer
or an authorized or certified service workshop. The
machine may not be put into operation again until the
damage has been properly fixed!
7. Shutdown
7.1 Temporary shutdown
For this type of shutdown, the machine remains installed
and is not cut off from the electricity supply. For tempo-
rary shutdown, the machine must remain completely sub-
merged so that it is protected from frost and ice. Make
sure the operating room and the pumped fluid cannot be
covered by ice. This ensures that the machine is always
ready for operation. During longer shutdown periods,
carry out a regular (monthly to quarterly) function run for a
period of 5 minutes.

Cleaning the container
First disconnect the container from the power supply.
Then unscrew the lid from the lifting unit. Now rinse the
container thoroughly with clean water. Then close the con-
tainer again.
Caution!
Only carry out a function run under the proper con-
ditions of operation and use. Never run the machine
dry. This can result in irreparable damage!
7.2 Final shutdown / storage
Switch off the system, disconnect the machine from the
electricity supply and dismantle and store it. Note the fol-
lowing information concerning storage:
Beware of hot parts!
When removing the machine, be careful of the tem-
perature of the housing components. These can heat
up to well above 40°C. Let the machine cool down to
ambient temperature before you touch it.
•
Clean the machine.
•
Store it in a clean, dry place, protect the machine
against frost.
•
Place it down vertically onto a firm foundation and se-
cure it against falling.
•
Seal the intake and discharge ports of pumps with
suitable material (such as foil).
•
Support the electric connecting lead on the cable
lead-in to help avoid a permanent deformation.
•
Protect the ends of the electric power cable from
moisture.
•
Protect the machine from direct sunshine as a pre-
ventive measure against brittleness in elastomer
parts and the propeller and casing coating.
•
When storing the machine in a garage please remem-
ber: Radiation and gases which occur during electric
welding destroy the elastomers of the seals.
Cleaning the container
First disconnect the container from the power supply.
Then unscrew the lid from the lifting unit. Now rinse the
tank thoroughly with clean water. Then fill the tank with
fresh water to a height of approx. 14 cm. The impeller of
the pump is then completely submerged. This prevents
the impeller from sticking to the suction cover. Then close
the container tightly again.
7.3 Restarting after an extended period of storage
Before restarting the machine, clean it of dust and oil de-
posits. Then carry out the necessary maintenance actions
(see "Maintenance"). Check that the mechanical shaft
seal is in good order and working properly. Once this work
has been completed, the machine can be installed (see
"Installation") and connected to the electricity supply by
a specialist. See "Start-up" for instructions on restarting.
Only restart the machine if it is in perfect condition and
ready for operation.
