Overview buffer tank
Key buffer tank
Description
1.
When the buffer tank’s lower control level “Start filling” is reached, the solenoid valve to the swim-
ming pool filter system closes and the solenoid valve for buffer tank filling opens. Buffer tank filling
starts.
2.
At the buffer tank’s upper control level “Stop filling”, the filling is stopped. This is followed by a
flushing cycle to clean the dissolving unit: initially for 20 seconds with acid, followed by 20 seconds
with water only. Afterwards, the solenoid valves switch back to normal operation.
3.
At the buffer tank’s “Minimum alarm” level, the dosing pump(s) are switched off. An alarm mes-
sage is shown on the display; the alarm output is active.
4.
At the buffer tank’s “Maximum alarm” level, an alarm message is shown on the display. The dosing
pump(s) continue(s) running.
Contact positions
When the container is half full, the level switches’ contacts are set as follows:
Level position
Contact

closed
Maximum level
open

An activated carbon filter (61) is screwed on top of the buffer tank. It is used to clean the chlorine-
containing air when filling the buffer tank and for venting and aerating.
The buffer tank is located in the collecting tub. An alarm switch (65) for leakages is installed in the
collecting tub.
