Fine Adjustment Of The Operating; Pressures - Kärcher WATERCLEAN 600 HP Betriebsanleitung

WTC 600 HP
• 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.

Fine Adjustment of the Operating

Pressures

In case of alterations to the system
adjustments, the following values must
not be exceeded under any circum-
stances:
• Pump pressure, max. 69 bar
• Drinking water amount, max. 650 l/h
• The concentrate amount must not ex-
ceed the operational start-up value
The system reacts somewhat time-
i
delayed to alterations of the regulation
valve. Therefore carry out the adjust-
ment at concentrate control valve (13)
only in small steps, and wait until
checking the respective effect.
(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).
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.
• Slowly shut the concentrate control valve (13)
in clockwise direction until either the flow rate
of 600 l/h is reached at the flow meter for drink-
ing water (42) or the pressure of 69 bar is
Version 06/05
reached at the pressure gauge for pump pres-
sure (11).
(2) Conducting capacity of the drinking
water has increased from _____
to _____ µS/cm
Small increases of the drinking water
i
conducting capacity do not influence
the drinking water quality.
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 drinking water conductance value
has increased to _____ µS/cm, the
Kärcher Service must be contacted.
(3) The difference between pump and
concentrate pressure has increased
by more than _____ bar
• Read the values at the manometer for the
pump pressure (11) and for the concentrate
pressure (12), and determine the differential
pressure.
