Smart-Sample-Tube
3 Transport and storage
Only transport the product inside the original packaging or a
suitable alternative. The sample gas probe must cool down
sufficiently prior to transport. Depending on the operating
conditions, this can take up to one hour.
CAUTION
Risk of injuries and fire
Never transport devices which have not cooled down suffi-
ciently!
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 50 °C (-4 °F
to 122 °F).
4 Installation and connection
Remove all on-site dust covers before installing the Smart
Sample Tube. These are located inside the G3/8" thread of the
sampling lance and inside the 35 mm (1.38 inch) port for con-
necting a heated line.
4.1 Installation site requirements
CAUTION
Equipment damage
Protect the device from 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.
The sample gas probes are intended for temporary, portable
gas sampling.
• Installation site and installation position are determined
based on requirements specific to the application.
• If necessary, the connection piece should be slightly tilted
toward the centre of the channel.
• Also ensure adequate and safe access during mobile use.
Particularly note the length required to install and unin-
stall the sample tube.
4.2 Installation
WARNING
Gas leakage, condensate, hot surfaces
Burns and / or health hazards due to gas / condensate!
a) The sample gas and/or condensate may be hazardous to
the health.
b) Parts near the sampling point may be hot.
c) The probe may become very hot due to the process
gasses.
ð Close the gas supply, if necessary flush the probe with air,
and allow the probe to cool down before beginning in-
stallation or maintenance.
ð Wear safety gloves and goggles.

4.3 Installing a heated sample gas line
Connecting a Smartline (recommended)
• Remove the plug from the probe casing (Fig. 1 and 2)
• Remove the nut and lock rings for the fitting (Fig. 3)
through this assembly opening and properly mount to
the Smartline tube
• Insert the Smartline into the casing from below and at-
tach the nut to the fitting through this assembly opening
• Tighten the nut with an SW14 open-end spanner
• Reinsert the plug in the casing
CAUTION! Never trim the connection pipe of the Smart-
line, or a proper connection can no longer be guaranteed.

Connecting a universal heated line
You can use the same procedure as for the Smartline, however
to maintain the IP rating and to minimise thermal bridges,
this may require an additional adapter between the heating
line and probe casing (Fig. 4). These are sold separately (spare
parts and accessories) and can be tailored to the specific ap-
plication. Trim the connection pipe for your sample gas line to
minimise the adaptation, thus thermal bridge.
NOTICE
IP degree of protection
The degree of protection (IP 44) was determined in laboratory
tests with heated line type Smartline connected. Compliance
requires a properly connected Smart Sample Tube.
Other types of heated lines can achieve the same degree of
protection with adaptations. Due to the variety of universal
heating lines, however, this must be ensured by the operating
company.
4.4 Connecting the calibrating gas line (optional)
The calibrating gas line (DN 4/6 or 1/4"-1/6" hose) can be con-
nected directly to the factory hose connection.
An optional check valve is sold separately.
