2 Safety
2.1 Intended use
The pump is intended solely for the following uses:
 Transferring liquids and gases
 For operation in accordance with the operating parameters
specified in the technical data of the supporting documents
2.2 Reasonably foreseeable misuse
The pump must not:
 be operated in an explosive atmosphere
 be used to transfer explosive media
 be used to transfer media whose compatibility with the pump
head, valves, diaphragms, and seals has not been proven
2.3 Responsibility of the user
The user is responsible for ensuring that the safety precautions in
these Installation Instructions are complied with. Applicable, safety,
accident prevention, and environmental protection regulations must
be complied with.
2.4 Product-specific risks
Remaining risks that were determined in a risk assessment are
described in this section. Safety precautions and warnings in this
section and in the other sections of the Installation Instructions
must be observed to prevent dangerous situations.
DANGER
Danger of injuries and damage to property due to dangerous
substances
Poisoning and chemical burns or unintended reactions caused by
leaking dangerous substances
 Observe the safety data sheets of the transferred media
 Before transferring a medium, check whether it can be
transferred safely in the specific application case.
 Ensure that the system is not subject to any risks of explo-
sion, also in extreme operating conditions (temperature,
pressure) or in case of malfunctions.
 Ensure the pump is used only by suitably trained, skilled
employees
 Clarify the wear resistance of the head material
 Check that the pump and the system do not leak at the op-
erating temperature of the transferred medium
 Regularly check the pump for damage
 Operate the pump only when you are sure it has no tech-
nical malfunctions
 Operate the pump in accordance with the technical data
 Work on the pump or fluid circulation system only after they
have been decontaminated and/or a decontamination decla-
ration is present

DANGER
Danger of injuries and damage to property due to leaks at the
interfaces to the pump head
Poisoning and chemical burns or unintended reactions caused by
leaking dangerous substances
 Wear personal protective equipment
 Connect the pump correctly
 Operate the pump only when you are sure it has no tech-
nical malfunctions
 Operate the pump in accordance with the technical data
DANGER
Danger of injuries and damage to property due to uncon-
trolled flow while the pump is not in operation
Poisoning and chemical burns or unintended reactions caused by
leaking dangerous substances
 Install a shut-off valve in the fluid circulation system
WARNING
Danger from magnetic field
The pump generates a strong local magnetic field, which may
cause pacemakers or other devices that are affected by magnetic
fields to malfunction.
 Ensure that these devices are kept at least 10 cm away
from the pump when it is operating
 If necessary, attach additional shielding devices

3 Installation
WARNING
Danger from incorrect installation
Injuries or damage to property from leaking media
 After installation, check the system for leaks with a safe
medium
 Observe the requirements for intended use
 Take precautions in the design of the end device so that
leaking liquids cannot come into contact with live compo-
nents
The following requirements apply to all activities described in this
section:
3.1 Installation location
The installation location must:
 protect the pump against immersion
 keep aggressive and flammable liquids and vapors away
 allow hoses to be connected without tensile or bending stress
 take account of cooling the pump drive
 ensure that any leaks can be handled
 have appropriate precautions if flammable media are used
3.2 Mechanical mounting
 Protect the product against impacts, knocks, and strong vibra-
tions
 For dimensions, installation positions, fluid connections, please
refer to the product data sheet
3.3 Connecting the fluid system
Use suitable means to check the fluid connection for leaks.
For more information regarding dimensions, please refer to the
data sheet.

3.4 Electrical connection
For terminal assignment, output data, and control requirements,
please refer to the data sheet
Observe the regulatory requirements for electrical installations:
 Overload protection and separating protective devices
 Contact protection and additional insulation
 Ground connections
 Protection against vibrations, tensile stress, and corrosion
3.4.1 DC coils
CAUTION
Danger from burns or fire, poisoning from flue gases
If the pump is connected incorrectly, it may overheat and catch
fire.
 Connect the pump to the correct voltage
 Operate the pump in accordance with the technical data
 Take suitable precautions to limit maximum power con-
sumption.
3.4.2 AC coils
DANGER
Danger from electric shock
 Connect the pump to the correct voltage
 Wear personal protective equipment
 Operate the pump only when you are sure it has no tech-
nical malfunctions
 Operate the pump in accordance with the technical data
 Ensure that the fluid circulation system is grounded
 Check the pump for damage regularly
 Disconnect the pump from the power supply when carrying
out maintenance work
 In case of fixed installation, install a maintenance switch

Installation Instructions FL 10 Initial start-up
KNF Flodos 173856_MA_FL10_EN_01.docx1

4 Initial start-up
The product must not be started up until it has been ensured that
the machine in which the product is to be installed meets the
requirements of the Machinery Directive 2006/42/EC, if applicable.
CAUTION
Danger of bursting of the fluid system due to overpressure.
The pump builds up pressure. With a closed system, the max.
permitted operating pressure may be exceeded, which can dam-
age the pump and the system.
 Prevent operation against a closed system
 Use only parts that come into contact with the fluid that are
designed to at least withstand the operating pressure of
the pump
 If necessary, take suitable measures to limit the maximum
system pressure
CAUTION
Danger of unexpected chemical reactions with water
Residues of water in the pump that come from testing in the
factory may react with the transferred medium.
 Before starting the pump for the first time, rinse it with a
medium that is uncritical as regards water
CAUTION
Danger from hot surfaces
The pump becomes hot during operation Burns from hot surfaces
or injuries from uncontrolled movements are possible.
 Do not touch the pump while it is operating.
 Ensure a sufficient supply of cool air and keep a safe dis-
tance between the pump and neighboring components.
 Operate the pump in accordance with the technical data
 If the temperature of the medium is above 50°C, take pre-
cautions to prevent burns from fluid components.
Before switching on the pump, check the following points:
 All hoses attached properly
 Specifications of the power supply correspond with the data on
the pump’s type plate
 Pump discharge not blocked
 All cables attached properly
 Contact protection for electrical connections and moving parts
installed
