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
Potentially explosive atmosphere
Explosion hazard if used in hazardous areas.
The device is not suitable for operation in hazardous areas
with potentially explosive atmospheres.
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, take special attention to the media tem-
perature with respect to temperature class T4. These vary in
addition to gas composition and ambient conditions. Where
necessary, the operator must install temperature sensors for
monitoring and must automatically shut down the sample
gas pump should the temperature exceed 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 chapter "Technical data".
Observe maximum temperature classes T4 for the pumps and
the allowed ambient temperatures and medium temperat-
ures.
DANGER
Danger of explosion due to exothermic reactions
Avoid catalytic materials in the conveyor pipelines and other
materials, e.g. male stud couplers, connecting to the sample
gas pump.
Depending on the particular medium conveyed (e.g. ethylene
oxide), a polymerisation of the medium may occur. Heat
build-ups are possible and constitute an ignition source. If
necessary, for clarification consult a technical department
that possesses sufficient chemical expertise.
DANGER
Explosion hazard
Flammable media fed into the pump may only be heated to a
maximum of 80 % of their respective ignition temperature.
CAUTION
Tilting risk
Damage of the device
Secure the device against any sudden translocation during
maintenance.
CAUTION
Hot surface
Burning hazard
According to the product type and operation conditions, the
temperature may exceed 50 °C during operation.
Depending on the conditions at the installation site it may be
necessary to provide these areas with appropriate warning
signs.
3 Transport and storage
Only transport the product inside the original packaging or a
suitable alternative.
The equipment must be protected from moisture and heat
when not in use. They must be stored in a covered, dry and
dust-free room at a temperature between -20 °C to +40 °C
(-4 °F to 104 °F). To avoid bearing damage, ensure a vibration-
free environment (v eff<0.2 mm/s).
Outdoor storage is prohibited. On principle the operator must
meet all applicable standards with respect to preventing dam-
age due to lightning, which could result in sample gas pump
damage.
