Frost Protection - Kärcher SB MB Bedienungsanleitung

Vent the dosing pump
The system compressed air supply must be in opera-
tion.
1. Turn the venting lever anticlockwise as far as it will
go.

2. Set the dosing amount to 100%.
3. Press the ventilation button repeatedly until the de-
tergent comes out of the venting line on the under-
side of the dosing pump without bubbles.
4. Reset the dosing quantity to the desired value, see
"Settings / Setting the dosing pumps / Standard set-
ting".
5. Turn the venting lever clockwise as far as it will go.
Refuelling
DANGER
Risk of fire
Fuel can ignite.
Observe the locally applicable regulations on the han-
dling of fuel.
Do not use unsuitable fuels as they can be dangerous.
ATTENTION
Risk of damage
If the fuel tank is empty, the fuel pump runs dry and can
get damaged.
Check the fuel tank filling level regularly.
Burner faults
Incorrect fuel can lead to burner faults and poor com-
bustion.
Only use the fuel specified in the "Technical data" sec-
tion.
Use heating oil with a winter operation additives (flow
improvers) if there is a risk of frost.
Fuel overflow
Fuel expands when warmed and can overflow.
Do not fill the fuel container to the brim.
1. Unscrew the cap of the filling nozzle.

2. Fill with fuel until the filling level display shows full.
Note
Make sure that no fuel overflows and gets into the in-
spection opening. During a later inspection, this fuel
could be mistaken for leakage.
3. Close the filling nozzle.
Replenishing softening salt
ATTENTION
Malfunctions possible
Unsuitable salt can interfere with the function of the
base exchanger.
Only use the softening salt in tablet form specified in the
"Accessories" chapter.
1. Remove the lid of the salt tank.
2. Fill the salt tank to the top with softening salt.
3. Fit the lid of the salt tank.
Note
An empty salt tank causes malfunction. Fill up the salt
tank at the latest when water is visible in the salt tank af-
ter removing the lid.
Salt consumption does not increase when the salt tank
is completely full.
In a correctly working system, the salt consumption is
constant in relation to the water consumption.
We recommend documenting the salt and water con-
sumption in an operating log.

Frost protection

The frost protection device consists of:
● Recirculation fan
● Hot air blower
● Frost protection circuit or frost protection with water
loss
● Washing station heater
● Emergency frost protection
● Heating cartridge in the oil tank
WARNING
Danger of accident
If there is black ice, there is a risk of accidents for the us-
ers of the washing bay.
Lock out washing stations when black ice forms to pre-
vent black ice accidents.
Note
The following features are guaranteed:
● Unrestricted washing with the high-pressure spray
lance down to -15°C. For systems with 4 washing
stations, it is recommended to lock out one washing
station below -10°C (for systems with 4 high-pres-
sure modules type 908 already at warmer tempera-
tures).
● Restricted washing with the washing brush at tem-
peratures below 0°C. During restricted washing, all
washing brushes must be checked regularly for ic-
ing. Foam washing with an iced washing brush can
damage the vehicle. If the washing brush is iced up,
the following measures must be taken:
1-tool version: Replace the combination spray
lance with a high-pressure spray lance.
2-tool version (option): Refrain from foam washing
(e.g. by giving instructions to the user).
● 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 im-
portant vehicle components. Therefore, prevent use
of the system below -15°C by locking out the wash-
ing stations.
● The system is frost-proof down to -20°C. Below -
20°C the device must be shut down as described in
the section "Shutting down in case of frost".
Prerequisites for frost protection
● The main switch must be in position 1.
● The doors of the system must be closed.
● An uninterruptible power supply, water supply and
fuel supply must be ensured.
● The water supply must be protected against frost.
● The fuel supply must be protected against frost (e.g.
heating cartridge in the tank, trace heating).
● Set up and install as described in the chapter "Set-
ting up the system".
● The hot air blowers are set correctly.
● All maintenance measures described in the "Mainte-
nance and care" chapter have been performed.
● All cleaning tools are returned to the storage com-
partments.
● The trigger guns with frost protection bore belonging
to the system are installed.
Washing station heater
Note
A prerequisite for the correct functioning of the washing
station heater is that the washing station is designed by
the customer in accordance with KÄRCHER's recom-
mendations.
The washing station area that can be heated is limited
by the corresponding heating capacity of the device. If
the heated area exceeds this value, frost protection is
not ensured. The number of washing stations that can
be heated is given in the chapter "Technical data / data
depending on hot water generation".
Snow coating and larger quantities of ice chunks that
have fallen off the vehicles require a very high heating
capacity. It is necessary to remove these deposits.
