Karcher A 2011201 manual Fine Adjustment of the Operating Pressures

Maintenance and Care Version 06/05 WTC 600 LP / MP

•Before screwing on the filter bowl, check the sealing ring (39) for damage.

•Screw on the filter bowl and tighten with the fil- ter wrench.

•Open the untreated water supply again and start the system with the main switch.

3.2.5Fine Adjustment of the Operating Pressures

In case of alterations to the system adjustments, the following values must not be exceeded under any circum- stances:

•Pump pressure, max. 21 bar (MP) or 14 bar (LP)

•Drinking water amount, max. 650 l/h

•The concentrate amount must not ex- ceed the operational start-up value

The system reacts somewhat time- i delayed to alterations of the regulation

valves. Therefore carry out the adjust- ment at the pressure control valve (14) and at the concentrate control valve

(13)only in small steps, and wait until checking the respective effect.

(1)Flow of drinking water has decreased from _____ to _____ l/h

Read off the amount of drinking water at the flow meter (42) and compare with the value taken when starting operation (see operational start-up record).

If the flow of drinking water has de- creased to _____ l/h , the following fine

adjustment is to be carried out.

If the fine adjustment does not lead to an increase in the drinking water flow, the Kärcher Service must be con- tacted.

•Slowly shut the pressure control valve (14) in clockwise direction until the desired amount is almost reached at the flow meter (42).

•Slowly shut the concentrate control valve (13) in clockwise direction until the respective set value is reached on both flow meters for con- centrate (43) and drinking water (42).

Notice: The quantity of concentrate will in- crease. This is correct.

•Carry out a readjustment on both valve levers, if required.

(2)Conducting capacity of the drinking water has increased from _____

to _____ µS/cm

Small increases of the drinking water i conducting capacity do not influence

the drinking water quality.

On the display of the control panel (10), read the current drinking water conductance value and compare with the value taken when starting oper- ation (see operational start-up record).

If the drinking water conductance value has increased to _____ µS/cm, the follow-

ing fine adjustment is to be carried out. If the fine adjustment does not lead to a decrease of the drinking water con- ductance value, the Kärcher Service must be contacted.

•Open the concentrate control valve (13) in coun- terclockwise direction in small steps until the con- ductance capacity has reached the set value.

•Shut the pressure control valve (14) in clock- wise direction in small steps until the drinking water amount in the viewing glass (42) has reached the set value.
