3. Safety
Note the safety precautions in chapters
6. Installation and connection, and 7. Operation.
The pumps are built according to the generally recognized rules of
technology and in accordance with the occupational safety and
accident prevention regulations. Nevertheless, dangers can result
during their use which lead to injuries to the user or others, or to
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 instructions, at all times.
Make sure that only trained and instructed personnel or specially
trained personnel work on the pumps. This especially applies to
assembly, connection and servicing work.
Make sure that the personnel has read and understood the operat-
ing instructions, and in particular the "Safety" chapter.
Observe the accident prevention and safety regulations when
performing any work on the pump and during operation.
Do not expose any part of your body to the vacuum.
Open housing parts with notice sticker (see fig. 1) only after
separating mains plug from power source.
When transferring dangerous media, observe the safety regula-
tions when handling these media.
Be aware that the pumps are not designed to be explosion-proof.
Make sure the temperature of the medium is always sufficiently
below the ignition temperature of the medium, to avoid ignition or
explosion. This also applies for unusual operational situations.
Note that the temperature of the medium increases when the pump
compresses the medium.
Hence, make sure the temperature of the medium is sufficiently
below the ignition temperature of the medium, even when it is
compressed to the maximum permissible operating pressure of the
pump. The maximum permissible operating pressure of the pump
is stated in the technical specifications (see chapter 4).
If necessary, consider any external sources of energy, such as
radiation, that may add heat to the medium.
In case of doubt, consult the KNF customer service.
Store all replacement parts in a protected manner and dispose of
them properly in accordance with the applicable environmental
protection regulations. Observe the respective national and inter-
national regulations. This especially applies to parts contaminated
with toxic substances.

6.1. Installation
ÎBefore installation, store the pump at the installation location to
bring it up to room temperature.
ÎSee chapter 4, Technical data, for the dimensions of pump.
ÎInstall the pump so that the motor fan can intake sufficient
cooling air.
ÎMake sure that the installation location is dry and the pump is
protected against rain, splash, hose and drip water.
ÎChoose a safe location (flat surface) for the pump.
ÎProtect the pump from dust.
ÎProtect the pump from vibration and jolt.
6.2. Connection
ÎOnly connect components to the pump which are designed for
the pneumatic data of the pump (see chapter 4).
ÎIf the pump is used as a vacuum pump, safely discharge the
pump exhaust at the pump’s pneumatic outlet.
A
marking on the pump head shows the direction of flow.
1. Remove the protective plugs from the pneumatic connectors of
the pump.
2. Mount accessory parts filter or silencer (if present).
If the pump is used as a vacuum pump, mount a silencer at the
pressure side if necessary. If the pump is used as compressor,
mount a filter at the suction side if necessary.
Before mounting the filter or silencer, unscrew the correspond-
ing hose connector from the threads in the pump head.
3. Connect the suction line and pressure line (N 86 K_.18: tube
ID 4 mm; N 811 K_.18: tube ID 6 mm).
4. Lay the suction and pressure line at a downward angle to
prevent condensate from running into the pump.

Tab. 4
7.2. Starting
ÎOnly operate the pump under the operating parameters and
conditions described in chapter 4, Technical data.
ÎMake sure the pump is used properly (see chapter 2.1).
ÎMake sure the pump is not used improperly (see chapter 2.2).
ÎObserve the safety precautions (see chapter 3).
WARNING
Hazard of the pump head bursting due to excessive
pressure increase
ÎDo not exceed max. permissible operating
pressure (see chapter 4).
ÎMonitor pressure during operation.
ÎIf the pressure exceeds the maximum permissi-
ble operating pressure, immediately shut down
pump and eliminate fault (see chapter 9. Troub-
leshooting).
ÎOnly throttle or regulate the air or gas quantity in
the suction line to prevent the maximum per-
missible operating pressure from being ex-
ceeded.
ÎIf the air or gas quantity in the pressure line is
throttled or regulated, make sure that the maxi-
mum permissible operating pressure of the
pump is not exceeded.
Excessive pressure (with all of the related hazards) can be
prevented by placing a bypass line with a pressure-relief valve
between the pressure and suction side of the pump. For further
information, contact your KNF technical adviser.
ÎWith the pump at a standstill, open pressure and suction lines
to normal atmospheric pressure.
Pump standstill

Operation

WARNING
A
utomatic starting can cause personal injury and
pump damage
When the operation of the pump is interrupted by the
thermal switch, the pump will restart automatically
after cooling down.
ÎAfter triggering of the thermal protection or in the
event of power failure, remove the pump’s mains
plug from the socket so that the pump cannot
start uncontrollably.
ÎAttempt work on the pump only if the pump is
separated from mains power.
7.3. Switching pump on and off
Switching pump on
The pump may not start up against pressure or vacuum during
switch-on. This also applies in operation following a brief power
failure. If a pump starts against pressure or vacuum, it may
block. This activates the thermal switch, and the pump
switches off.
ÎMake sure that no vacuum or pressure is present in the lines
during switch-on.
ÎSwitch on pump with mains switch (see fig. 2 and 3, depending
on pump type)
Switching off the pump/removing from operation
ÎWhen transferring aggressive media, flush the pump prior to
switch-off to increase the service life of the diaphragm (see
chapter 8.2.1).
ÎSwitch off pump with mains switch (see fig. 2 and 3, depending
on pump type).
ÎOpen pressure and suction lines to normal atmospheric pres-
sure.
ÎDisconnect the power source.
