Operating instructions

Intended use

Evaporation residue such as ole-
fines, paraffins and other hydro-
carbon compounds gets into the
liquid gas during manufacture
and via the logistics chain. These
oily substances are transported
from the liquid gas cylinder in
the form of aerosols (liquid drop-
lets in the micrometer range) in
the vaporous flow of gas, and
are deposited in the gas pressure
regulation systems, pipelines or
valves.
The Truma gas filter has been
specially developed for filtering
these aerosols, and removes
99 % of the oily particles thanks
to its efficient replaceable filter
cartridge.

The Truma gas filter is
not designed for filtering
gaseous residual materials.
Gaseous residual materials such
as phthalates (softeners) also
occur in the flow of gas in vapor-
ous form.
In spite of a high degree of sepa-
ration of 99 % of the liquid aero-
sols that occur, vaporous soften-
ers can damage the diaphragms
and seals of downstream fittings
and consumers, and may cause
the gas pressure regulation sys-
tem to fail.
No warranty given for
failure of gas pressure
regulation systems, valves
or other components in the
liquid gas system caused by
oil contamination or other
foreign substances in the
liquid gas.
The proportion of evaporation
residue in vaporous liquid gas
depends on various factors.
As well as the removed quan-
tity, the pressure and the tem-
perature during removal, the
gas cylinder that is used and
the country in which it is used
are determining features.
The filter cartridge must be
checked for residue (e.g.
oil or clear liquids) at regular
intervals, but at least every time
the cylinder is changed).
Replace the filter cartridge
– if there are residues on the fil-
ter cartridge or in the filter cup,
– at least every 2 years.
