P2.x AMEX
4.1 Requirements to the installation site
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.
CAUTION
Avoid vibrations and resonances
The operator is responsible to mount the pump in a way that
vibrations and resonance do not cause premature failure res-
ulting in creating an effective ignition source.
The sample gas pump must be assembled and connected as
well as disassembled in a non-Ex zone with the unit cooled
down.
Never block the vent. The exhaust air, including from adjacent
units, must not be immediately suctioned in.
When installing without a Bühler mounting bracket, ensure
adequate distance between the motor and 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, along with 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

4.2 Installation
CAUTION
Damage to the device
Protect the device, especially the gas inlets and tubes, against
dust, falling parts and external impact.
P2.2 AMEX/P2.82 AMEX
When installing the P2.2 AMEX/P2.82 AMEX on mounting
plates, use the mounting bracket included and only use the
rubber/metal bumpers included. Operation without rubber/
metal bumpers is prohibited. These must also be used when
installing the pump on an existing substructure. For the hole
pattern in the mounting bracket and the motor foot, please
refer to the Technical Data at the end of the operating and in-
stallation instructions.
P2.4 AMEX/P2.84 AMEX
Please refer to assembly drawing 42/025-Z02-02-2 when in-
stalling the P2.4 AMEX/P2.84 AMEX sample gas pump. Before
beginning the installation, ensure that the sample gas pump
is complete. You will also require 6 x M6 bolts of suitable
length and nuts for installation.
The pump head on all pump types can only be aligned turned
by 0° or 180°.
4.3 Special condition moist sample gas
Applications where the sample gas is still moist may result in
condensate forming in line and the pump body. In these
events the pump head must be suspended (pump body facing
down).
If the pump was not ordered this way, it can easily be conver-
ted on site.
Install the line between the gas output and condensate drain
with a grade so the condensate can drain and does not collect
inside the pump or the lines.
4.3.1 Alteration of hanging pump bodies
CAUTION
Damage to the device
Especially with pump head pointing down, make sure that no
dust or small parts can intrude the pump through the ventil-
ations slot. Nevertheless, the slot must not be covered dir-
ectly. If this is not possible, the pump must not be mounted
with pump head pointing downward.
Please refer to assembly drawing 42/025-Z02-01-2 in the ap-
pendix for the conversion.
• Remove the three cross-tip screws (9) and remove the con-
sole cover (8) from the pump console (5). This exposes the
crank gear (10) and the Motor flange or, depending on
pump model, the intermediate flange.
• The Pump console attaches to the flange with four
hexagon screws (7) and lock washers (6). Completely un-
screw these, holding the pump console, and rotate it 180°
on the centring of the flange.
