(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.
1 Cover
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.
ƽ 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.
ṇ
Warning
Risk of flocculation or other undesirable
chemical reactions. Only use chlorine-free
drinking water from the drinking water test-
ing tap to mix the chemicals.
1 Drinking water testing tap
The dosing depends on the filling level in
the dosing container.
Fully emptied dosing container.
Î
Fill 20 l drinking water in the dosing can.
Î Use the measuring beaker to measure
20 times the quantity (WPC 5000...) or
10 times the quantity (WPC 2500...) in-
dicated in the dosing table and fill it into
the dosing container.
Î Fill up the dosing container up to the
"200 l" mark (WPC 5000...) or to the
"100 l" mark (WPC 2500..) with chlo-
rine-free drinking 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. 2 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
Read the filling level of the dosing con-
tainer on the scale, for e.g. 50 l.
Î Determine the refill quantity; for that de-
duct the filling level that you have read
from 200 l. In the example: 200 l – 50 l =
150 l.
Î From the dosing table, ascertain the re-
quired quantity of the corresponding
chemicals. In the example: 15 x the
quantity for 10 l water.
Î Measure the ascertained quantity of the
corresponding chemical and fill it into
the dosing container.
Î Fill up the dosing container up to the
"200 l" mark with chlorine-free drinking
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.
Note
With the WPC 2500 BW-AM system, the
dosing container holds 100 l. Please set
100 l here instead of 200 l and proceed as
indicated above.
