Short answer: The system senses the reservoir level with conductivity electrodes; as it empties, it feeds water and concentrate on separate lines and stops when FULL — mixing happens only in the reservoir (post-mix).
The Cycle
1 · Empty detection
When the level drops below the electrode tip, a fill decision is made.
2 · Filling
The water valve opens; shortly after, the concentrate pump kicks in.
3 · Full → stop
When the electrode bridge reads FULL, the valve and pump switch off.
4 · Emptying
As product is consumed, the level drops; the cycle repeats by itself.
Water and Concentrate Separate, Mixing in the Reservoir (Post-Mix)
Water and concentrate arrive on separate lines; they mix only in the reservoir. This improves hygiene in the feed lines. Hygiene advantage →
Capacity
It scales for 1-4 reservoirs; each channel is independent. Capacity variations →
