7.4 flocculant metering (optional)
NOTICE!
Overdosing of flocculants
Cause: Metering flocculant during downtime or
backwashing of the filter leads to overdosing of
flocculant and the water to go cloudy.
The peristaltic pump DULCO
®
flex DF4a must be
locked electrically with the filter of the swimming
pool and the peristaltic pump DULCO
®
flex DF4a
may only run during regular operation of the filter.
For this electric locking, the pause contact input of
the peristaltic pump must be switched with the filter
control, as described in the separate operating
instructions of the peristaltic pump.
Alarm message flocculant
The level switch of the flocculant suction lance is
intended for connection to the controller. If there is
a shortage of flocculant, a central alarm message
is triggered.
Optionally, the metering system can be delivered with flocculant
metering. The flocculant is metered by means of a peristaltic pump
DULCO
®
flex DF4a that is mounted to the plate. A separate oper‐
ating manual is provided for the installation of the peristaltic pump
DULCO
®
flex DF4a.
When using flocculant metering, cloudy swimming pool water is an
indicator that the wrong flocculant or a wrong dosage of flocculant
was used. In the event of cloudy swimming pool water, please con‐
tact your swimming pool manufacturer and/or chemicals retailer.
