GAS 222.15
4 Installation and connection
4.1 Installation site requirements
Sample gas probes are intended for flange mounting.
– 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.
– The installation site should be protected from the weather.
– In addition, adequate and safe access for installation and future maintenance work should be provided. Particularly follow
the uninstalled size of the probe tube!
If the probe is transported to the installation site in pieces, it will first need to be assembled.
4.2 Installing the sampling tube (optional)
The sampling tube, if necessary with the fitting extension, must be screwed in. The probe is then attached to the mating flange
using the included seal and nuts.
4.3 Installing the downstream filter (optional)
NOTICE
The downstream filter and the O-ring for the handle must be inserted prior to first star-
tup.
Operating without downstream filter prohibited!
O-ring handle
Attach an O-ring suitable for the expected ambient temperature to the handle.
Attach the downstream filter to the handle. Then carefully insert the handle with
filter in the gas probe and turn 90° to secure.
Verify the handle is seated correctly. When seated correctly it locks onto the filter
housing.
4.4 Insulation
On heated probes completely insulate any exposed flange areas and, if applicable, the connection piece to absolutely prevent
thermal bridges. The insulating material must meet the application requirements and be weatherproof.
