Hot Surface; Installation And Connection; Electrical Connections - Bühler technologies P1.1 Notice De Montage

P1.1, P1.1E
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
Please note:
• Only transport in the original packaging or a suitable al-
ternative
• Only store in covered, dry, dust-free spaces, NOT outdoors
(lightning strike!)
• Storage temperature -20 °C to +40 °C
• Storage spaces mustn't have ozoniferous installations
(e.g. fluorescent illuminants, mercury vapor lamps, high
voltage apparatuses)

4 Installation and connection

Remove any transport locks on the fan blade and check the
equipment for damage prior to installation. This could be a
damaged housing, supply cables, etc., among other things.
Never use equipment with obvious damage.
4.1 Requirements to the installation site
CAUTION
Damage to the device
Protect the equipment against dust, falling objects and ex-
ternal impacts.
Stroke of lightning
Outdoor installation is forbidden. As a matter of principle, the
operator must regard all applicable standards according pre-
vention of damage due to lightning, which may otherwise
damage the device.
Sample gas pump P1.1 (without enclosure) is a built-in unit
and must be operated within an enclosure that provides suffi-
cient protection against touching live or moving parts (fan).
Ingress of water or dust and dirt must be prevented.
Air ventilation must not be obstructed and exhausted air - in-
cluding air from adjacent units - must not be sucked in dir-
ectly.
The motor is suitable for ambient temperatures between 0 °C
to +50 °C and altitude of height ≤ 1000 m above sea level.
Please refer to chapter "Appendices" of this manual for fur-
ther information about ambient parameters at the installa-
tion site.
4.2 Installation
Use suitable rubber-metal buffers when installing to mount-
ing plates. We recommend buffers with a diameter or 10 mm,
a height of 10 mm and a shore hardness of 70. These are also
available from us.
BX420020 ◦ 03/2020
The base angle of the sample gas pump features 4x M4
tapped holes for mounting the buffers. Suitable buffers and
assembly brackets are accessories which may be ordered sep-
arately from us.
While installing the sample gas pump, there must be suffi-
cient spacing between the motor and the rear wall (20mm).
If you are using a sample gas pump with housing (type P1.1E),
the required distance between the housing and the rear wall
is 50mm. This is due to the minimum permitted bending ra-
dius of the power supply line.
The specific mounting bracket for the various product vari-
ants can be obtained as an accessory. Using the appropriate
mounting bracket guarantees the correct distance between
the device and the rear wall.
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.
4.4 Connecting gas lines
The G1/4 female threads for the respective screw-in connec-
tions are factory closed with plastic plugs to protect from dirt.
Screw-in connections are generally not included in delivery,
but are sold separately for metric or for imperial installation.
Avoid mixed-material installation, i.e. metal piping to plastic
bodies. If this cannot be avoided in isolated applications,
screw the metal connections into the pump body with care,
never use force.
Lay the lines so the line at the inlet and outlet remains flexible
for an adequate distance.
The pumps are marked IN for inlet and OUT for outlet at the
mounting ring. Be sure the gas line connections are tight.

4.5 Electrical connections

WARNING
Hazardous electrical voltage
The device must be installed by trained staff only.
CAUTION
Wrong mains voltage
Wrong mains voltage may damage the device.
Regard the correct mains voltage as given on the type plate.
