DEFINITION OF THE REGENERATION FREQUENCY FOR THE TIME SYSTEM :
volume of water treated (softened)
volume of water for daily consumption
E.g.:
Supposing that for DOUBLE 85 a daily consumption of 4200 litres is required (with hardness of 30
°
F)
17.000:4200=4 the number to set (in this case regeneration takes place every 4 days).
CORRESPONDING REGENERATION TIMES:
1 C =
6 minutes backwash
2 C =
30 minutes brine suction
3 C =
30 minutes slow rinse
4 C =
8 minutes rapid rinse
Height of floater = 500 mm
SYSTEM VOLUME - VOLUME TIME
N.B.
The number of litres of water to be set on the display is 1/100 that found in the table. E.g. value in table is 17.000.
The value to be set (17.000:100) = 170.
The litres are counted with a pulse every 100 litres, without changing the actual quantity of water.
N.B.
The litres of softened water shown in this table are obtained with intake water with a total hardness of max. 45
°
F
and salinity not exceeding 500 PPM, without oils, colourless and without turbidity.
Water consumption per regeneration is calculated as a function of the following parameters:
- time of each phase
- water flowrate at the drain
- operating pressure
