11 Troubleshooting
Fault
SALt is shown on the display.
Unit is not providing softened
water or blended water.
Unit is not providing softened
water or too low a flow rate.
Dyed flushing water during the
start-up.
If the fault cannot be rectified with this troubleshooting guide, our customer service team must be contac-
ted, providing information of the series and production number (see type label on the reverse of the unit).
Cause
Too little regenerating agent in
the supply cavity (5).
Pipe pressure too low, so suc-
tion speed is too low.
No regenerating agent in the
supply cavity (3).
Power supply interrupted.
Adjusting spindle for blending
(V) not correctly set.
Primary pressure too low.
Abrasion particles of the
exchanger resin.
Rectification
Refill the regenerating agent
and press OK until the
SALt display disappears.
Confirm with OK.
If this occurs again, please
consult customer service.
Refill the regenerating agent.
Wait 3 hours for the brine for
form and then run the regene-
rating process manually for both
softening columns one after
the other.
Create an electrical connection.
Adjust as per the "Setting of
the blended water hardness"
section in the start-up instruc-
tions.
Increase primar y pressure
(adjust pressure reducer if
required) and activate manual
regeneration.
Repeat start-up flushing.
