Deutsch

– The electrical connections must be 

done by an electrician according to 

IEC 60364-1. 

– Never touch damaged or ripped mains 

cables.  If required, pull out the plug 

from the socket immediately.

– Never operate the unit with damaged 

cable. 

The following symbols are used in this op-

erating manual:



Danger

Indicates an immediate threat of danger. 

Failure to observe the instruction may re-

sult in death or serious injuries.

몇

Warning

Indicates a possibly dangerous situation. 

Failure to observe the instruction may re-

sult in light injuries or damage to property.

Note

Indicates useful tips and important infor-

mation about the product.

The plant is used for treating surface wa-

ter, water from natural springs and river 

water. 

Due to the modular structure, turbid sub-

stances, hardeners, salts, bacteria and 

water can be separated depending on the 

quality of raw water. 



Danger

Risk of injury if the plant is not installed 

properly.  Risk to health on account of 

poorly treated drinking water.  The plant 

may be put into operation only when set-

up, installed and prepared for operation by 

skilled and authorized personnel.

Î

Check the connection of the plant to 

the raw water source. 

Î

Ensure uninterrupted flow of the gen-

erated drinking water into a tank or a 

suitable user-side facility. 

Note

The driking water must be able to flow out 

without any counter-pressure.  The height 

difference must not be more than 3 m.

Note

If the plant is fitted with one or more dos-

ing stations, then it needs to be ensured 

that this has been connected properly and 

filled up. 

Î

Fill up dosing station (refer chapter 

"Maintenance and Care/ Maintenance 

jobs")

Î

Check whether the mains plug of the 

dosing pumps of the dosing stations is 

connected to the sockets of the plant. 

Î

Check the position of the operating 

swtich:

"Automatic“ position: 

the plant is 

controlled by an external floater switch 

in the drinking water tank.

"Manual" position: the plant is man-

ually switched on and off using the 

main switch.

Î

Turn the main switch to position "1"; 

drinking water production will start.

Alternating display of:

– Plant/ version number and operating

ductance.

몇

Warning

Risk of damage. If the plant is to be shut 

down for more than 14 days, then Kärcher 

Customer Service must carry out some 

preservative tasks.

Î

Turn main switch to "0"; the plant will 

stop production of drinking water.

Note

Do not switch off the plant overnight! The 

media filter is automatically cleaned dur-

ing the night. There is a risk of damage to 

the plant if you do not do this cleaning.



Danger

Health hazard on account of poor quality 

of drinking water. . The control tasks out-

lined in this maintenance plan are to be 

carried out according to the schedule in 

order to ensure the quality of drinking wa-

ter.  If the deviations in the target values 

cannot be corrected by taking the pre-

scribed measures, then stop production of 

drinking water and inform Kärcher Cus-

tomer Service immediately.

Warning

Danger of damage to the plant. The follow-

ing values should not be exceeded when 

you make changes to the plant settings:

–

Max. pump pressure 2.1 MPa

 (21 bar)

–

Maximum drinking water volume:

– The concentrate quantity should not fall 

below the value at the time of startup. 

–

Do not change the setting of the pump 

regulation valve.

Note

There is a time delay before the plant reacts 

to the changes done to the regulating 

valves. Hence do the settings at the pres-

sure regulation valve and the concentrate 

regulation valve in small steps and wait for 

the respective effect.

(1) Drinking water flow has fallen from 

_______ l/h to _______ l/h

1 Flow meter for drinking water

2 Flow meter for concentrate 

3 Concentrate regulation valve

4 Pressure regulation valve

5 Flow meter for concentrate backflow

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 concentrate backflow has almost 

achieved the target value. 

Î

Close the concentrate regulation valve 

slowly in the clock-wise direction until 

the required target value is reached for 

the two flow meters of the concentrate 

and the drinking water.

Î

Readjust both the valves if required. 

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. 

1 Flow meter for drinking water

3 Pressure regulation valve

4

Display

5 Manometer for membrane input pres-

sure

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

Open the concentrate regulation valve 

in small step by turning it in the anti-

clockwise direction until the conductivity 

has reached the target value.

Î

Close the pressure regulation valve in 

small steps in the clock-wise direction 

until the flow meter of the drinking water 

has reached the target value.

몇

Warning

Danger of damage to the RO membrane. 

While closing the pressure regulation valve, 

ensure that the membrane input pressure 

does not exceed 2.1 MPa (21 bar).

Note

The purpose of this setting procedure is to 

increase the concentrate quantity.

Î

Repeat these setting steps if required. 

Eventually, the original drinking water 

quantity will no longer be reached.
