Karcher WPC 600 SW-A Инструкция по эксплуатации онлайн [16/72] 7136
16 English
Î Screw on the filter pot and tighten it us-
ing the filter key.
Î Restart the raw water flow.
Î Switch on the unit using the "ON/OFF"
key.
몇 Warning
Danger of damage to the plant. The follow-
ing values should not be exceeded when
you make changes to the plant settings:
– Maximum pump pressure 7 MPa
– Maximum drinking water quantity 600 l/
h
– Concentrate quantity min. 1200 l/h
Note
There is a time delay before the plant reacts
to the changes done to the regulating valve.
Hence do the settings at the pressure regu-
lation valve in small steps and wait for the
respective effect.
(1) Drinking water flow has fallen from
_______ l/h to _______ l/h
1 Pressure regulation valve
2 Flow meter for drinking water
Î 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:
Î Close the pressure regulation valve in a
clock-wise direction until the flow meter
for the drinking water has almost
achieved the target value.
Note
Inform Kärcher Customer Service if this fine
regulation does not lead to any changes to
the drinking water flow.
(2) Conductivity of drinking water has in-
creased from _____µS/cm to _____µS/cm
Note
Small increases in the conductivity of drink-
ing water does not affect the quality of the
drinking water.
Î Read the current conductivity value on
the display of the operating panel and
compare it to the value at the time of
start-up (see start-up report). If the
drinking water conductivity has in-
creased to _____µS/cm, then you need
to rinse the membrane of the RO filter
unit:
Î Reduce the drinking water output by
opening the pressure regulation value
to approx. 200 l/h.
Î Operate the plant for approx. 1 hour;
then reset the nominal output by closing
the pressure regulating valve.
Î Check again the conductivity of the
drinking water.
Note
If rinsing the membrane does not result in
lower conductivity values, then inform
Kärcher Customer Service.
(3) Difference between pump and con-
centrate pressure has increased by
more than ___ MPa
1 Manometre for pump pressure
2 Manometer for concentrate pressure
Î Read the value on the manometer for
the pump pressure and the concentrate
pressure and determine the differential
pressure.
Î Compare the ascertained differential
value with the value set at the time of
startup (see startup report).
Î The membrane filter unit must be
blocked if the differential pressure has
increased by more than ______ MPa;
no further adjustments are possible.
Stop production of drinking water and
inform Kärcher Customer Service.
Danger
Risk of burns injury on account of chemi-
cals. Please wear safety gloves and safety
goggles while handling acid-resistant
chemicals.
Note
The values for dosing the different chemi-
cals are based on the raw water analysis
and the plant output. Kärcher Customer
Service will enter the dosing quantities re-
quired for your plant in the following table at
the time of startup.
1Cover
2 Mixing rod
3 Dosing pump
4 Dosing container
Î Wear safety gloves and safety goggles.
Î Remove the can from the dosing sta-
tion.
Danger
Risk of injury on account of chemical reac-
tion. The dosing stations should not get in-
terchanged and be filled up with the wrong
chemicals.
몇 Warning
Risk of flocking or other undesirable chem-
ical reactions. Only use the drinking water
from WPC 600 SW for mixing chemicals.
The dosing depends on the filling level in
the dosing container.
Fully emptied dosing container.
Î Fill 10 l drinking water in the dosing con-
tainer.
Î Using a measuring beaker, measure 7.5
times the quantity mentioned in the dos-
ing table and add it to the dosing con-
tainer.
Î Fill up the dosing container up to the
mark "75 l" with chlorine-free water.
Î Close the cover of the dosing station.
Î Pull out the mixing rod from the dosing
container until the stop and push it back
into the container.
Repeat this process for approx. 5 min-
utes until the chemicals are fully mixed.
Î Deaerate the dosing pump according to
the instructions in the chapter "Mainte-
nance and Care".
Partially emptied dosing container:
Î Check the filling level of the dosing con-
tainer, for e.g. 35 l.
