Consumables - Kärcher WPC 100 FW Manual Del Usuario

Screw on the filter pot and tighten it
using the filter key.
Restart the raw water flow.
Set main switch to "1".
Fine regulation of the operating
pressures
Warning
Danger of damage to the plant. The fol-
lowing values should not be exceeded
when you make changes to the plant
settings:
Maximum pump pressure 0.6 MPa
–
Maximum drinking water quantity
–
100 l/h
The concentrate quantity should not
–
fall below the value at the time of
startup.
Note
There is a time delay before the plant
reacts to the changes done to the reg-
ulating valves. Hence do the settings at
the pressure regulation valve and the
concentrate regulation valve in small
steps and wait for the respective effect.
(1) Drinking water flow has fallen
from 100 l/h to 80 l/h
1 Concentrate regulation valve
2 Pressure regulation valve
3 Flow meter for drinking water
4 Flow meter for concentrate
Close the pressure regulation valve
in a clock-wise direction until the
flow meter for the drinking water
has almost achieved the target val-
ue.
Close the concentrate regulation
valve slowly in the clock-wise direc-
tion until the required target value is
reached for the flow meters of the
concentrate and the drinking water.
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) Difference between pump and
concentrate pressure has increased
by more than 0.1 MPa
1 Manometer for concentrate pres-
sure
2 Manometre for pump pressure
Read the value on the manometer
for the pump pressure and the con-
centrate pressure and determine
the differential pressure.
Compare the ascertained differen-
tial 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 0.1 MPa. In-
form Kärcher Customer Service.
Mixing the chemicals
Danger
Risk of burns injury on account of
chemicals. Please wear safety gloves
and safety goggles while handling acid-
resistant chemicals.
Note
The values for dosing the different
chemicals are based on the raw water
analysis and the plant output. Kärcher
Customer Service will enter the dosing
quantities required for your plant in the
following table at the time of startup.
The dosing quantities refer to a fully
empty dosing station. Calculate the
corresponding value if the dosing sta-
tion is partially empty.

Remove the can from the dosing
station.
Danger
Risk of injury on account of chemical
reaction. The dosing stations should
not get interchanged and be filled up
with the wrong chemicals.
Fill up 2 l drinking water from WPC
100 FW in the completely empty
tank.
Measure the quantities of the re-
spective chemicals given in the dos-
ing table and fill up the can.
Fill up the can up to the mark "10 l"
with drinking water from WPC 100
FW.
Close the can with the lid.
Mix the water and the chemical
thoroughly by shaking the can.
Remove the lid and insert it in the
holder bracket of the dosing station.
Slide the suction unit into the can
and place the can back into the dos-
ing station.
Deaerate the dosing pump accord-
ing to the instructions in the chapter
"Maintenance and Care".
