Warning
Danger of damage to the plant. The follow-
ing values must never be exceeded:
– Maximum pump pressure 7 MPa
– Maximum drinking water quantity 5,000
l/h
– Concentrate quantity min. 10,000 l/h
Note
The pressure settings can only be changed
via the speed of the pump. Only KÄRCHER
customer service technicians are permitted
to adjust this.
(1) Drinking water flow has fallen from
_______ l/h to _______ l/h

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 has fallen to ______
l/h, contact the KÄRCHER customer
service.
(2) Conductivity of drinking water has
increased 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.

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 value has increased to
_____μS/cm, contact the KÄRCHER
customer service.
ƽ 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

Wear safety gloves and safety goggles.
 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.
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 indicated in the
dosing table 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. 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. 2 min-
utes until the chemicals are fully mixed.
Note
With the WPC 5000 SW-AM system, the
dosing container holds 200 l.
