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.
Do not expose the device to combustible or explosive gas mix-
tures.
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. 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.
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 drying the winding.
The motor shaft should be turned occasionally to ensure the
entire bearing remains lubricated. To do so, remove the three
cross-tip screws (9) of the console cover (8) and remove. 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.

CAUTION
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.

4.1 Requirements for the set-up location

CAUTION
Equipment damage
Protect the equipment, particularly gas connections and gas
lines, from dust, falling objects, as well as external blows.
Lightning
On principle, the operator must meet all applicable standards
with respect to preventing damage to the equipment due to
lightning, which could result in equipment damage.
Never block the vent, and the exhaust air – including from ad-
jacent units – must not be immediately suctioned in.
When installing without Bühler mounting bracket, be sure
the motor is far enough from the back panel (at least 40 mm).
The sample gas pumps are rated for altitudes <= 1000 m.
They're available in various styles and the specific technical
data may vary.
Therefore always note all device-specific data on the pump
and motor type plate and their specific limits - see Technical
Data.

4.1.1 Outdoor installation

The sample gas pumps were not specifically designed for out-
door setup. The operating and environmental conditions are
crucial for the required types of protection and any additional
measures required, such as:
• adequate protection from the weather
• Adjusting the maintenance intervals (e.g. cleaning and re-
placing wear parts)
Use suitable measures and regular inspections to prevent
damage to the equipment from e.g.:
• Corrosion
• Sunlight (temperature peaks and damage from
UV rays)
• Moisture from condensation (e.g. due to rapid temperat-
ure changes or downtimes)
• Icing
• Insects and microbes
• other animals, e.g. martens, etc.
Please remember that all technical operating parameters of
the equipment must also be met with outdoor installation.
Specifically:
• Maximum or minimum operating temperatures
• Degree of protection
