1. About this document
1.1. Use of the Operating and Installation Instruc-
tions
The Operating and Installation Instructions are part of the pump.
➔Forward the Operating and Installation Instructions to any
subsequent owners of the pump.
Customer-specific project pumps (pump models which begin with
"PJ" or "PM") may differ from the Operating and Installation In-
structions.
➔In case of project pumps, take note of any additionally agreed
specifications.
1.2. Symbols and markings

It also indicates the possible consequences of failure
to observe the warning. The signal word (i.e. “Warn-
ing”) indicates the level of danger.
➔Here you will see actions for avoiding the danger
and potential consequences.

2. Use
2.1. Intended use
The pumps are exclusively intended for transferring gases and
vapors.
Owner's responsibility
Only install and operate the pumps under the operating parameters
and conditions described in Chapter 4. Technical data.
Only complete pumps may be taken into service.
Make sure that the installation location is dry and the pump is
protected against water in the form of rain, spray, splashes and
drips.
Before using a medium, check whether the medium can be trans-
ferred danger-free in the specific application case.
Before using a medium, check the compatibility of the materials of
the pump head, diaphragm, and valves with the medium.
Only transfer gases which remain stable under the pressures and
temperatures occurring in the pump.
2.2. Improper use
The pumps must not be operated in an explosive atmosphere.
The pumps are not suitable for transferring dust.
The pumps are not suitable for transferring liquids.
The pumps are not suitable for use with aggressive media. Other
pumps in the KNF product line are designed for use with aggres-
sive media. Please contact us for more information.
The pumps must not be used to create vacuum and pressure
simultaneously.
Never apply positive pressure to the suction side of the pump.

3. Safety
Observe the safety precautions in Chapters
6. Installation and connection and 7. Operation.
The pumps are built according to generally recognized rules of
technology and in accordance with the pertinent occupational
safety and accident prevention regulations. Nevertheless, potential
dangers during use can result in injuries to the user or others or in
damage to the pump or other property.
Only use the pumps when they are in a good technical and proper
working order, in accordance with their intended use, observing the
safety advice within the Operating and Installation Instructions, at
all times.
Make sure that only trained and instructed personnel or specially
trained personnel work on the pumps. This applies especially to
assembly, connection, and servicing work.
Make sure that all personnel have read and understood the Oper-
ating and Installation Instructions, especially the "Safety" chapter.
Observe the accident prevention and safety regulations when
performing any work on the pump and during operation.
Ensure that the pump is separated from the mains and is de-
energized.
When transferring dangerous media, observe the safety regula-
tions for handling such media.
Be aware that the pumps are not designed to be explosion-proof.
Make sure that the temperature of the medium is always sufficient-
ly below its ignition temperature, to avoid ignition or explosion. This
also applies to unusual operating situations.
Note that the temperature of the medium increases when the pump
compresses the medium.
Hence, make sure that the temperature of the medium is sufficient-
ly below its ignition temperature, even when it is compressed to
maximum permissible operating pressure of the pump. The pump's
maximum permissible operating pressure is stated in the Technical
data (see Chapter 4).
Consider any external sources of energy, such as sources of
radiation, that could additionally heat the medium.
In case of doubt, consult the KNF customer service.
All replacement parts should be properly stored and disposed of in
accordance with the applicable environmental protection regula-
tions. Ensure adherence to the pertinent national and international
regulations. This applies especially to parts contaminated with toxic
substances.
For the purposes of Machinery Directive 2006/42/EC, pumps are
“partly completed machinery,” and are therefore to be regarded as
not ready for use. Partly completed machinery may not be com-
missioned until such time as it has been determined that the ma-

chine in which the partly completed machinery is to be assembled
conforms to the provisions of the Machinery Directive 2006/42/EC.
The following essential requirements of Annex I of Directive
2006/42/EC (general principles) are applied and observed:
−General Principles No. 1
−No. 1.1.2. / 1.1.3. / 1.3.1. / 1.3.3. / 1.3.4. / 1.4.1. / 1.5.1.* /
1.5.2.* / 1.5.8. / 1.5.9. / 1.7.4. / 1.7.4.1. / 1.7.4.3.
(* only for pumps with AC motor)
As these partly completed machinery are OEM-models the power
supplies and the equipment for disconnecting and switching-off the
partly completed machinery respectively have to be considered
when mounting as well as over-current and overload protective
gear.
In addition a protection against mechanical parts in motion and hot
parts, if existing, has to be provided when mounting.
The pumps conform to the Directive 2011/65/EU.
The following harmonized standards are met:

Fig. 6: Pump head
Diaphragm pumps transfer, compress (depending on pump ver-
sion), and evacuate gases and vapors.
The elastic diaphragm (4) is moved up and down by the eccentric
(5) and the connecting rod (6). In the downward stroke it aspirates
the gas to be transferred via the inlet valve (2). In the upward
stroke, the diaphragm presses the medium out of the pump head
via the outlet valve (1). The diaphragm hermetically seals the
working chamber (3) from the pump drive (7).

6. Installation and connection
Always install the pumps under the operating parameters and
conditions described in Chapter 4. Technical data.
Observe all safety precautions (see Chapter 3).
6.1. Setting up or installing the pump
➔Choose a safe location (flat surface) for the pump.
➔Before installation, store the pump at the installation location to
bring it up to ambient temperature.
Refer to Fig. 7 (N 813.3 ANE), Fig. 8 (N 813.4 ANE),
Fig. 9 (N 813.5 ANE), Fig. 10 (N 813.3 ANDC-B and N 813.3

➔When setting up or installing the pump, make sure that the fan
can draw in an adequate amount of cooling air.
For pumps with fan: Install the pump so as accidental finger con-
tact is with the fan is impossible.
➔Make sure that the installation location is dry and the pump is
protected against water in the form of rain, spray, splashes and
drips.
The pump motor's IP protection class is provided on the type
plate.
➔Set up or install the pump at the highest point in the system to
prevent condensate from collecting in the pump head.
➔Protect the pump against dust.
➔Protect the pump against grease and oils.
➔Protect the pump against vibration and impact.

6.2. Electrical connections
GEFAHR
Extreme danger from electrical shock
➔Only have the pump connected by an authorized
specialist.
➔Only have the pump connected when the power
supply is disconnected.
➔When connecting the device to a power source, the relevant
standards, directives, regulations, and technical standards
must be observed.
➔In the electrical installation, arrangements (complying with EN
60335-1) must be made for disconnecting the pump motor
from the electrical supply.
➔For pumps with AC motor:
The motors of the pump must be protected according to EN
60204-1 (protection against excess current, or overloading).
➔For operating current see type plate.
➔It is recommended that an additional “Emergency Stop” switch
is installed.
➔The pump must be installed so that contact with live parts
(electrical connection) is impossible.
Pumps with AC motor
1. Make sure that the power supply data match the data on the
pump type plate.
The voltage must not vary by more than + 10% and - 10% from
that shown on the type-plate.
2. Connect earth (ground) wire to the motor.
3. Connect motor wires.
Pumps with brushless DC motor
1. Make sure that the power supply data match the data on the
pump type plate.
The voltage must not vary by more than + 10% and - 10% from
that shown on the type-plate.
2. Electrical connect of the pump according to Fig. 12, page 20.
Note the proper polarity (see marking on the motor). Incorrect
lead connection will damage electronics of brushless dc motors
(type designation ending with B). The supply wires have in-
verse-polarity protection on the motor board for this purpose,
while the control-voltage wires do not have this protection
function.
