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

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.

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.
