P2.x AMEX
DANGER
Diffusing pumped media
Explosion hazard! Formation of explosive atmosphere due to
escaping flammable gases.
When operating the sample gas pumps with media that tend
to diffuse strongly, such as hydrogen (H
tions, it is essential to note that these are not permanently
technically leak-proof due to their design. To ensure safe op-
eration, the official regulations for installation and operation
must be observed. In addition to regular leakage checks, suit-
able technical measures such as gas monitoring devices, tech-
nical ventilation, etc. must be provided depending on the in-
stallation situation.
CAUTION
Tipping hazard
Equipment damage.
Secure the device against tipping, sliding and falling.
CAUTION
Hot surface
Burning hazard
According to the product type and operation conditions, the
temperature of the housing may exceed 50 °C during opera-
tion.
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. It must be stored in a covered, dry and dust-
free room at a temperature between -20 °C and +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 not permitted. In principle, the operator
must meet all applicable standards with respect to preventing
damage due to lightning, which could result in damage to the
sample gas pump.
Especially with sample gas pumps P2.x AMEX-O2 (item no.:
42.............-O2), any contamination of components in contact
with the media must be ruled out.
Storage areas must not contain any equipment generating
ozone, e.g. fluorescent lighting, mercury vapour lamps, high-
voltage electrical equipment.
After prolonged storage or downtimes, test the insulation res-
istance of the winding, phase against phase and phase
against mass, prior to initial operation. Moist windings can
cause current leaks, flashovers and breakdown. The insulation
resistance of the stator winding must be at least 1.5 MΩ meas-
ured at a winding temperature of 20 °C (68 °F). Values below
this require the winding to be dried.

The motor shaft should be turned occasionally to ensure the
entire bearing remains lubricated. To do so, remove the three
cross-tip screws (9) from the console cover (8). This exposes
the crank gear (10). You can now turn the motor shaft on it.
For the item numbers, please refer to the assembly drawing
42/025-Z02-01-2 in the appendix.

Contusion hazard
Contusion of the fingers
Don't have your fingers caught between eccenter and slide.
4 Installation and connection
Check the equipment for damage before installation. Among
other things, this could be a damaged housing, supply cables,
etc.. Never use equipment with obvious damage.
Diffusing pumped media
Explosion hazard! Formation of explosive atmosphere due to
escaping flammable gases.
When operating the sample gas pumps with media that tend
to diffuse strongly, such as hydrogen (H
tions, it is essential to note that these are not permanently
technically leak-proof due to their design. To ensure safe op-
eration, the official regulations for installation and operation
must be observed. In addition to regular leakage checks, suit-
able technical measures such as gas monitoring devices, tech-
nical ventilation, etc. must be provided depending on the in-
stallation situation.
Use appropriate tools
According to DIN EN 1127-1, the operator is responsible to se-
lect and use appropriate tools.
Contamination of cleaned components
With sample gas pumps P2.x AMEX-O2 (item no.: 42.............-
O2), contamination with oil, grease, dust, particles, lint, hair,
etc. must be ruled out for fire protection reasons when work-
ing on components that come into contact with media. If ne-
cessary, adapt your operational and organisational measures
with regard to the work clothing to be used, hygiene regula-
tions, etc. If necessary, move such work to a suitable, cleaner
work area.
Unit leakage rate
With sample gas pumps P2.x AMEX-H2 (item no.: 42.............-
H2), the leakage rate is tested at the factory to verify compli-
ance with defined limit values. This may deviate after loosen-
ing or retightening cap screws and/or pipe fittings. Carry out
a new test if necessary.
