Backwash
Brine draw and slow rinse
2
(down flow)
3 Fast rinse
4 Brine refill
5 Always put these pins at the end of the setting
Cycle times are factory preset.
Each pin or hole is equivalent to 2 minutes.
It is highly recommended to verify if each cycle time is
adapted to specific site conditions.
To modify the cycle time of each regeneration, add or
remove pins.
Example: view diagram on the right
1- Backwash: it goes from 10 to 14 minutes
2- Brine draw and slow rinse: it's reduced from 60
to 40 minutes
3- Fast rinse: it's reduced from 10 to 6 minutes
4- Brine refill: it's reduced from 20 to 12 minutes.
The 9000/91000/9500 valve has a brine refill cycle. Time needs to be calculated
(in minutes ) taking into account the following parameters:
- The flow regulator in the brine tank expressed in gallon per minute (gpm)
- The amount of salt needed to regenerate the resin total volume.
- A litre of water can dissolve roughly 0,362 kg of salt.
Note : 1 gallon = 3,785 l
Example:
For a 0,25 gallon par minute (gpm regulator), 6 kg of salt do dissolve, calculate this way to know
the amount of minutes to set on the program wheel.

As it is only possible to set the time on even numbers, the timer has to be set on 18 minutes.
