Maintenance and Care
The equipment may be put into operation only when set-up, installed and prepared for oper-
ation by an authorized KÄRCHER specialist dealer.

ure
3.1 Starting Operation
Before starting operation:
•
Make sure that the equipment is connected to
the untreated water source and the respective
transporting gear, e. g., admission-pressure
unit.
3.1.2 Filling the Metering Stations
If the system is equipped with one or
more metering stations, it must be en-
sured that these are correctly filled and

connected.
• Put on protective clothing.
The drinking water must be able to run
off without counterpressure. The height
difference must not exceed 3 m.
• Open the lid (27) of the metering station (30).

In case an admission-pressure unit
is necessary, it will be installed by a
Kärcher service technician.
i
The admission-pressure unit consists of a
pump (21) and a control device (22). The operat-
ing condition of the pump is indicated with three
indicator lights:
•
•
•
Green (24): Ready for operation
Yellow (25): Pump delivering
Red (26):

The metering stations must not be
mixed up or mistaken, meaning filled
with the wrong chemical.

• Add the corresponding amount of chlorine-free
drinking water.
• Shut the lid of the metering station.
• Pull the mixing rod (28) out of the metering
station to the stop and push back in again.
Repeat this procedure for approx. 5 minutes
until the chemical is completely mixed.

Maintenance and Care
If the metering container was com-
pletely empty, the metering pump (29)
may have possibly drawn in air. In this
case, bleed the air from the pump as
described in Section 3.2.3.
3.1.3 Switching On the Equipment
•
Check if the pumps of the metering station,
sand and activated carbon filter are connected
to the respective power outlets (18 / 19) at the
switch box (8).
•
Check if the operating mode switch (9) is in the
correct position “Automatic” or “Hand”.
In the “Automatic” operating mode, the
system is controlled via an external float
switch in the drinking water tank.
i
In the “Hand” operating mode, the sys-
tem is switched on and off manually via
the main switch.
•
Switch the main switch (20) to the “I” position;
the system starts the drinking water produc-
tion.

3.2.3 Bleeding the Metering Pump
• On the control panel, acknowledge the mal-
function indication with the RETURN key but-
ton (36); the system starts.
The metering pump must be bled when the pump
has drawn in air (e. g., because the metering con-
tainer is completely empty).
•
The system stops; the “Motor/hard water“ mal-
function indication is shown in the display.
3.2.4 Replacing the Fine Filter
Check the pressure difference at manometers (15)
and (16). Replace the filter insert when over 0.8 bar:
• Switch off the equipment at the main switch (20).
• Stop the untreated water supply.

• Place a bucket under the untreated water drain
cock (37) and open the cock.
• Wait until no more water emerges out of the
cock, then shut the cock again.
• Attach the filter wrench (41) to the filter bowl
(40) and screw off the filter bowl.

•
Unscrew the bleeding screw (34) by one turn.
Press the MANUAL pushbutton (33) until the
medium flows without bubbles through the

• Remove the filter insert (38) from the filter bowl
and replace with a new one.

•
Before screwing on the filter bowl, check the
sealing ring (39) for damage.
Screw on the filter bowl and tighten with the fil-
ter wrench.
Open the untreated water supply again and
start the system with the main switch.
Notice: The quantity of concentrate will in-
crease. This is correct.
• Carry out a readjustment on both valve levers,
if required.
3.2.5 Fine Adjustment of the Operating
Pressures
10
In case of alterations to the system
adjustments, the following values must
not be exceeded under any circum-
stances:
• Pump pressure, max. 21 bar (MP) or
14 bar (LP)
• Drinking water amount, max. 650 l/h
• The concentrate amount must not ex-
ceed the operational start-up value

The system reacts somewhat time-
delayed to alterations of the regulation
valves. Therefore carry out the adjust-

ment at the pressure control valve (14)
and at the concentrate control valve
(13) only in small steps, and wait until
checking the respective effect.
(2) Conducting capacity of the drinking
water has increased from _____
to _____ µS/cm
(1) Flow of drinking water has decreased
from _____ to _____ l/h
Small increases of the drinking water
conducting capacity do not influence
the drinking water quality.
i
Read off the amount of drinking water at the flow
meter (42) and compare with the value taken
when starting operation (see operational start-up
record).
On the display of the control panel (10), read the
current drinking water conductance value and
compare with the value taken when starting oper-
ation (see operational start-up record).
If the flow of drinking water has de-
creased to _____ l/h , the following fine
adjustment is to be carried out.
If the fine adjustment does not lead to
an increase in the drinking water flow,
the Kärcher Service must be con-
tacted.
If the drinking water conductance value
has increased to _____ µS/cm, the follow-
ing fine adjustment is to be carried out.
If the fine adjustment does not lead to a
decrease of the drinking water con-
ductance value, the Kärcher Service
must be contacted.
•
•
Slowly shut the pressure control valve (14) in
clockwise direction until the desired amount is
almost reached at the flow meter (42).
• Open the concentrate control valve (13) in coun-
terclockwise direction in small steps until the con-
ductance capacity has reached the set value.
Slowly shut the concentrate control valve (13)
in clockwise direction until the respective set
value is reached on both flow meters for con-
centrate (43) and drinking water (42).
• Shut the pressure control valve (14) in clock-
wise direction in small steps until the drinking
water amount in the viewing glass (42) has
reached the set value.

pressure (12), and determine the differential
pressure.
Observe the maximum pressure of 21 bar
(MP) or 14 bar (LP) at the manometer (11)!
• Compare the differential pressure with the
value taken when starting operation (see oper-
ational start-up record).
•
Repeat the adjustment steps, if required. The
original drinking water amount may possibly
not quite be reached.
If the differential pressure has in-
creased by more than _____ bar, then
the RO filter membrane is clogged.
Readjustment is no longer possible.
(3) The difference between pump and
concentrate pressure has increased
by more than _____ bar
Stop the drinking water production and
notify the Kärcher Service.
•
Read the values at the manometer for the
pump pressure (11) and for the concentrate
3.2.6 Mixing the Chemicals
When working with chemicals, always wear protective clothing.
Values for the metering of the various chemicals result from the untreated water analysis and
the system capacity.
Upon starting operation, the Kärcher service technician enters the required metering amounts
for your equipment into the following metering table.

used.
This water is taken from the drinking
water sampling valve (44).
• Determine the required amount of the respec-
tive chemical from the metering table.
Example: 4 x the amount for 10 l water.
• Measure the determined amount of the respec-
tive chemical and fill into the container.
• Refill amount of water to the “75 l” mark and
mix in accordance with Section 3.1.2.
3.3 Switching Off the Equipment
44
If the equipment is not operated for
periods exceeding 14 days, it must be
preserved by the Kärcher Service.
Otherwise permanent damage must be
expected.
The metered addition is carried out dependent of
the level in the metering container.
• Switch the main switch (20) to the “O” position;
the equipment stops the drinking water produc-
tion.
Completely emptied metering container:
•
Fill 10 l of drinking water into the metering con-
tainer.
Never switch off the equipment over-
night! Otherwise the automatic clean-
ing of the pre-filter is not carried
through. Danger of damage to the
equipment is given!
•
With a measuring cup, measure the 7.5 -fold
amount mentioned in the “10 Liter Water” col-
umn of the respective chemical and fill into the
container.
•
Fill the container with drinking water to the “75
l” mark and mix according to Section 3.1.2.
