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.
4.5 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.
