Frost protection (option)

The frost protection device consists of a hot air blower and an-
tifreezing circulation or frost protection with lost water.
Note: The presence of a frost protection system en-
sures the following properties:
● Restricted washing operation at temperatures be-
low – 5 °C. In restricted washing operation the
washing brush must be regularly checked for icing.
Brush washing with an iced washing brush can
damage the vehicle. If the washing brush is iced up,
the washing brush must be disabled or, in the case
of the 1-tool version, the combination spray lance
must be replaced with a high-pressure spray lance.
Please contact your Customer Service responsible
if washing operation is to be extended to lower tem-
peratures. At temperatures below –15 °C, washing
makes no sense because an ice coating forms on
the vehicle. This ice coating can even impair the
function of important vehicle components. For this
reason, you must lock the system at temperatures
less than –15 °C.
● Frost protection of the system down to –20 °C. At
temperatures less than–20 °C the "Frost shutdown"
procedure is to be performed.
WARNING
Frost protection water running onto the washing sta-
tion can lead to the formation of black ice under frosty
conditions.
Insert the high-pressure gun into the brush chute after use.
WARNING
Black ice on the washing station presents an in-
creased danger of accidents.
Lock the washing station if there is a danger of black ice.
Prerequisites for frost protection
● An uninterruptible power supply and water supply
must be ensured. The water supply must be protect-
ed against frost.
● Technically correct erection and installation of the
system.
● The hot air blower is set correctly.
● All maintenance measures described in the "Mainte-
nance and care" chapter have been performed.
● All cleaning tools are placed back in the tool holders.
● The high-pressure gun with frost protection bore be-
longing to the system is installed.
● The hose line from the system to the cleaning tool has
not been extended or replaced with a longer hose.
● The temperatures stated above relate to the instal-
lation site. Temperatures stated in weather forecasts
are secondary.
Hot air blower
The hot air blower heats the interior of the system to
provide frost protection.
