Discolouration of
4 filtrate (brownish
or milky)
Issue with
coffee machine
(corrosion,
5
limescale
deposits, gypsum
deposits)
76
Root cause
Water consumption outside of
product specification (too low,
too high)
Regular supply of bypass water
during peak demand
Membrane clogged
(Non-electric) pump defective
PURITY C500 MinUp was
subjected to an impact
Insufficient line pressure
Capacity of pre-filter is exhausted
(PURITY C Quell ST, PURITY
C50 Fresh)
Measures service technician
Make sure that the usual water
consumption of the coffee machine
meets the specifications of
PROGUARD Coffee
Minimum
required filtrate 10 litres/day
withdrawal
Maximum 80 litres/day
permissible
30,000
filtrate
litres/year
withdrawal
The water consumption of the
coffee machine should not exceed
the maximum filtrate production
per hour (depending on the inlet
pressure) too often, otherwise the
bypass valve will open too often.
3 bar ~10l/h
4 bar ~13l/h
5 bar ~16l/h
6 bar ~20l/h
• Measure the line pressure
• If the line pressure is <3 bar,
install a booster pump
• Even at a line pressure of 3–5
bar, an installation is possible to
increase the filtrate production
per hour
Replace the PURITY C150
PROGUARD cartridge
Replace the (non-electric) pump
Flush the PURITY C500 MinUp
cartridge until the discolouration in
the filtrate has vanished
Check the line pressure. If the
line pressure is <3 bar, install an
electric booster pump
Compare assumed and actual water
consumption with the FlowMeter.
If the actual water consumption is
greater than assumed: Adjust the
amount of water consumption in the
App and the FlowMeter and replace
the PURITY C pre-filter
