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 gase-
ous residual materials.
Gaseous residual materials such
as phthalates (softeners) also
occur in the flow of gas in vapo-
rous form.
In spite of a high degree of se-
paration of 99 % of the liquid
aerosols that occur, vaporous
softeners can damage the
diaphragms and seals of down-
stream fittings and consumers,
and may cause the gas pressure
regulation system to fail.
No warranty given for
failure of gas pressure re-
gulation systems, valves or other
components in the liquid gas
system caused by oil contamina-
tion 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 quantity, the
pressure and the temperature
during removal, the gas cylinder
that is used and the country in
which it is used are determining
features.
Truma recommends changing
the filter cartridge every 2 years
during the gas check as a pre-
cautionary measure. It can be
decided whether to make the
change sooner by checking the
saturation indicator at regular
intervals (e.g. when the cylinder
is changed).
