P1.3
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.
CAUTION
Use appropriate tools
According to DIN EN 1127-1, the operator is responsible to se-
lect and use appropriate tools.

4.1 Requirements to 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.
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 installation and the connection as well as the dismantel-
ing of the sample gas pump have to be made in an EX-free
area and in cooled down condition.
Sample gas pump P1.3 is a built-in unit and must be operated
within an enclosure that provides sufficient protection
against touching live or moving parts (fan) (IP54). 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
CAUTION
Damage to the device
Protect the device, especially the gas inlets and tubes, against
dust, falling parts and external impact.
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.
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.
When installing the sample gas pump, always ensure an ad-
equate amount of space between the motor and the back wall
(20 mm).
When using a sample gas pump with housing (type P1.3E), the
required spacing between the housing and back wall is
50 mm. This is based on the minimum required bend in the
connection line.
The specific mounting brackets for the different product ver-
sions are available as accessories. Using the correct mounting
bracket ensures the proper spacing between the device and
the back 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 the gas lines

A minimum of 20 cm of tubing or piping must be installed
between the sample gas pump and other system elements in-
stalled in the gas outlet according to the flow chart (e.g.
cooler, analyser, filter, flow regulator, etc.) to ensure compli-
ance with the temperature classes.
The G1/4" threaded holes 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. piping on plastic bod-
ies. If this cannot be avoided in isolated applications, screw
the metal connections into the PTFE pump body with care,
never use force.
