Malfunctions Explanation Remedy
No flow. The shut-off valves are not
open completely.
Open the shut-off valves
completely
The exchanger capacity is
low. A softening or phosphate
system is connected
upstream. Connect the mixed-bed
cartridge directly to the raw
water network.
Contaminated raw water. Connect a filter upstream
and wait for the lines to be
flushed.
Clean the sieve elements in
the base and in the lid.
The mixed-bed cartridge has
not been fully bled.
Bleed the mixed-bed
cartridge completely.
The mixed-bed cartridge is
used up. Replace the resin bag.
The residual conductivity
rises rapidly after a long
period of operational
downtime. Re-Ionisierung has occurred. Allow the water to drain
without being used until the
residual conductivity abates.
The flow rate is very low. The hose line is kinked. Re-lay the hose line.
The hose line is clogged. Disconnect the hoses from
the system and flush them
out thoroughly.
The sieve elements are
clogged. Clean the sieve elements in
the base and in the lid.
The flow rate is very high The flow stabiliser in the raw
water connection is defective. Replace the flow stabiliser.
The residual conductivity
has exceeded the limit
value. The mixed-bed resin is
depleted. Replace the resin bag.
The conductivity is high
even with a new resin bag
Resin bag fitted incorrectly Fit the resin bag correctly.
Flow rate too high
