Maintenance and Care
Version 06/05
• 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.
3.2.5
Fine Adjustment of the Operating
Pressures
(1)
Flow of drinking water has decreased
from _____ to _____ l/h
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).
• Slowly shut the pressure control valve (14) in
clockwise direction until the desired amount is
almost reached at the flow meter (42).
• 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).
Notice: The quantity of concentrate will in-
crease. This is correct.
• Carry out a readjustment on both valve levers,
if required.
(2)
Conducting capacity of the drinking
water has increased from _____
to _____ µS/cm
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).
• Open the concentrate control valve (13) in coun-
terclockwise direction in small steps until the con-
ductance capacity has reached the set value.
• 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.
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
i
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.
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.
i
Small increases of the drinking water
conducting capacity do not influence
the drinking water quality.
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.
