2 Safety regulations
This product has no dangerous ignition sources when ob-
serving regulations and operating parameters in these oper-
ating instructions. Installation into a complete system can
pose new hazards the manufacturer of this sample gas pump
has no control over. If necessary, perform a risk assessment of
the complete system this product will be installed into.
Observe the relevant national safety regulations for the in-
stallation site and the generally applicable state of the art
when configuring and building the complete system. These
can be determined through applicable harmonised standards,
e.g. EN 60079-14 among others. Additional national regula-
tions pertaining to initial operation, operation, maintenance,
repairs, and disposal must be observed.
Avoid any exothermic reactions in your system, do not use
materials with a catalytic effect in the conveyor lines. Danger-
ous rises in temperature may otherwise occur. Sample gas
pump materials in contact with mediums are specified in this
operating manual to facilitate the safety assessment.
Adiabatic compression is part of the physical operating prin-
ciple of bellows pumps. Dangerous rises in temperature can-
not be ruled out when exceeding the operating parameters.
Avoid these dangerous conditions. If necessary, protect the en-
tire system against flashback. Follow these notes and the ap-
plicable national regulations and prevent malfunctions to
avoid personal injury and property damage.
The operator of the system must ensure:
• The equipment is installed by a professional familiar with
the safety requirements and risks,
• Safety notes and operating instructions are available and
observed,
• The permissible data and operating conditions are ob-
served,
• Protective devices are used and the required maintenance
is performed,
• The unit is disposed according to the law.
DANGER
Electrical voltage
Electrocution hazard.
a) Disconnect the device from power supply.
b) Make sure that the equipment cannot be reconnected to
mains unintentionally.
c) The device must be opened by trained staff only.
d) Regard correct mains voltage.

DANGER
Danger of explosions, danger of poisoning from poison-
ous corrosive gases
During maintenance work, depending on the medium used,
explosive and/or poisonous corrosive gases could escape, and
this could lead to a danger of explosion or could be hazardous
to health.
a) Inspect the leak tightness of your sampling system before
putting the device into operation.
b) Ensure that gases that are hazardous to health are dis-
charged safely.
c) Turn off the gas supply before beginning any mainten-
ance or repair work and flush the gas lines with inert gas
or air. Secure the gas supply so that it cannot be turned
on unintentionally.
d) Protect yourself during maintenance from poisonous /
corrosive gases. Wear appropriate protective equipment.
DANGER
Explosion hazard
Life and explosion risk may result from gas leakage due to im-
proper use.
a) Use the devices only as described in this manual.
b) Regard the process conditions.
c) Check tubes and hoses for leakage.
DANGER
Adiabatic compression (explosion hazard)!
In case of adiabatic compression, high gas temperatures may
occur. The operator is responsible to consider this situation.
Make sure to obey the allowed technical specifications and
ambient conditions (see data sheet), take special attention to
the media temperature with respect to temperature class T3
or T3C. These vary in addition to gas composition and ambi-
ent conditions. Where necessary, the operator must install
temperature sensors for monitoring and must automatically
shut down the sample gas pump should the temperature ex-
ceed the limits.
DANGER
DANGER - Explosion danger in case of high temperat-
ures
Temperature of the device depends on the medium temper-
ature. Correlation between medium temperature and tem-
perature classes is given in the data sheets.
Observe maximum temperature classes T3 or T3C for the
pumps and the allowed ambient temperatures and medium
temperatures.
