Heat insulation
Heat build-up will occur if heating hoses are
routed through a closed channel or shaft.
Remedy: hoses may not touch one another.
Furthermore, suffi cient ventilation is to be pro-
vided.
If, for example, powder-like substances, adhe-
sives or other thermally insulating materials ac-
cumulate on heating hoses, then overheating will
occur at these locations.
Remedy: eliminate the cause with regular
cleaning to remove such materials.
Heat build-up will be caused by surrounding the
heating hose with other materials. The heating
hose will overheat at such points. If the sensor
area is surrounded, then the remainder of the
hose will cool off.
Bundling or routing that permits contact between
hoses will lead to overheating at points of con-
tact.
Remedy: route with open space between
hoses.
Do not fasten clips or brackets so tightly that they
cause the hose’s outer braid to be pressed inter-
nally against the heat conductor.
Disregard for this rule can lead to damage of the
protective braid and the hose.
Openly routed hose lines along paths where there
is vehicle or pedestrian traffi c are to be protected
against damage from abrasion and or deforma-
tion, e.g. by using hose bridges.
False Right
Appropriate measures are to be taken to arrange
and affi x hose lines to prevent them from be-
ing damaged externally by external mechanical
infl uences; this includes the scraping of hoses
against components or one another. To the ex-
tent necessary, hoses are to be secured in place,
for example, by protective jackets. Sharp-edged
components are to be covered.
Hose brackets are to be avoided at points where
they would prevent the hose’s natural free move-
ment and length changes.
Where hose lines are exposed to high external
temperatures they must either have suffi cient
physical separation from the external heat source
or be protected by appropriate measures (e.g.
shielding).
