ATTENTION
PROTECT THE BREATHER VALVE FROM BLOCKAGES.
If this optional pipeline is connected using the ¼ "NPT thread, it must have a minimum
internal diameter of 8 mm. With the pipeline connected (comply with the length details
in chapter 2.4), IP 66 protection is achieved and a vent line flow rate of around
10.5 l/min is possible

ATTENTION
Flame barriers can generally only be replaced by the manufacturer. Please
contact your TAC
Surfaces which come into contact with gas must be free of grease, oil, solvents and
other impurities.
Gases must not be contaminated or falsified when being transported from the source
(pipeline or cylinder) to the measuring instrument. This applies to all gases. Route the
gas pipelines to the measuring instrument. Use the pipework diagram specified and
prepared by the system operator. Ensure that every pipeline and every gas route is fitted
with the required safety and shut-off equipment. All pipelines are to be kept as short as
possible. Use only tight, clean stainless steel gas pipes.
Prevent dirt and/or moisture getting into the device as it could possibly
falsify the measurements or cause damage. Controls and pipe couplings
with low dead spaces are to be given preference.
