Fine regulation of the operating
pressures
Warning
Danger of damage to the plant. The fol-
lowing values should not be exceeded
when you make changes to the plant
settings:
Max. pump pressure 1.6 MPa

(16 bar)
Maximum drinking water volume:

The concentrate quantity should not
–
fall below the value at the time of
startup.
Do not change the setting of the
–
pump regulation valve.
Note
There is a time delay before the plant
reacts to the changes done to the reg-
ulating valves. Hence do the settings at
the pressure regulation valve and the
concentrate regulation valve in small
steps and wait for the respective effect.
(1) Drinking water flow has fallen
from _______ l/h to _______ l/h
1 Flow meter for drinking water
2 Flow meter for concentrate
3 Concentrate regulation valve
4 Pressure regulator valve
5 Flow meter for concentrate back-
flow
Read the quantity of drinking water
at the flow meter for drinking water
and compare it to the value when
the plant was started (see start-up
report). If the drinking water flow
ahs fallen to ______ l/h, then do the
following fine regulation:
Close the pressure regulation valve
in a clock-wise direction until the
flow meter for the concentrate back-
flow has almost achieved the target
value.
Close the concentrate regulation
valve slowly in the clock-wise direc-
tion until the required target value is
reached for the two flow meters of
the concentrate and the drinking
water.
Readjust both the valves if required.
Note
Inform Kärcher Customer Service if this
fine regulation does not lead to any
changes to the drinking water flow.
2,500 l/h
(2) Conductivity of drinking water has
increased from _____µS/cm to
1,320.86
_____µS/cm
gal/h
Note
Small increases in the conductivity of
gal/h
drinking water does not affect the qual-
ity of the drinking water.

pressure
Read the current conductivity value
on the display of the operating pan-
el and compare it to the value at the
time of start-up (see start-up re-
port). If the drinking water conduc-
tivity has increased to _____µS/cm,
then you need to rinse the mem-
brane of the RO filter unit:
Open the concentrate regulation
valve in small step by turning it in
the anti-clockwise direction until the
conductivity has reached the target
value.
Close the pressure regulation valve
in small steps in a clock-wise direc-
