(3) Difference between pump and con-
centrate pressure has increased by
more than ___ MPa
1 Manometre for pump pressure
2 Manometer for concentrate pressure
Read the value on the manometer for
the pump pressure and the concentrate
pressure and determine the differential
pressure.
Compare the ascertained differential
value with the value set at the time of
startup (see startup report).
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.
Mixing the chemicals
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.

Wear safety gloves and safety goggles.
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.
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.
Fill 20 l drinking water in the dosing can.
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.
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.
Close the cover of the dosing station.
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.
Deaerate the dosing pump according to
the instructions in the chapter "Mainte-
nance and Care".
Partially emptied dosing container:
Read the filling level of the dosing con-
tainer on the scale, for e.g. 50 l.
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.
From the dosing table, ascertain the re-
quired quantity of the corresponding
chemicals. In the example: 15 x the
quantity for 10 l water.
Measure the ascertained quantity of the
corresponding chemical and fill it into
the dosing container.
Fill up the dosing container up to the
"200 l" mark with chlorine-free drinking
water.
Close the cover of the dosing station.
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.
