For the operation with solvents, acids or brines the following applies:
a) The permitted operating temperature with detergent fluids of the named groups "solvents", "brines" and "acids" is limited to max.
60 °C by Kärcher.
b) The autoignition temperature of all involved substances (cleaning media and soiling / residue in the container) and their mixtures may
not be lower than the following temperature limits:
Devices with ATEX declaration T4:
Ignition temperature for gases >= 170 °C
Ignition temperature for dust >= 205 °C
Devices with ATEX declaration T3: Ignition temperature for gases >= 250 °C
Ignition temperature for dust >= 300 °C
This means that the ignition temperature of the substances must be higher than the above stated temperature.
Only the operator is responsible for the determination and observance of this temperature limit.
c) The ambient temperature of the installation must be within the range from +2 °C to max. +40 °C during operation.
d) In case that the physical-chemical aggressiveness or corrosive properties of the substances and their mixtures increases regarding
their material resistance and operating safety due to the heating of the involved substances (cleaning medium and soiling / residue)
to max. 60 °C, the operator must ensure that stainless steel (corrosion-resistant steel) of grade 1.4301 and nonferrous heavy metals
of grade 2.1086 and similar material alloys are not corroded.
e) For additional risks that may arise due to the increased temperature (e.g. from gases, fumes, hot surfaces or the like), suitable pro-
tective measures for the operating personnel must be ensured by the operator.
f) In general, it must be expected that the wear of the components increases with increasing temperature of the cleaning medium when
using aggressive cleaning media. Thus, the maintenance and inspection intervals for the device must be shortened if it is operated
with aggressive media and increased temperatures.
