Manual Regeneration - Rain Soft EC4 Serie Manual Del Usuario

Brine Draw / Slow Rinse Cycle
After the system is backwashed for several minutes, the valve moves to the brine draw position. In this posi-
tion, the valve creates a vacuum to pull the brine solution out of the brine tank. The brine solution flows
slowly through the mineral bed, removing the hardness ions that are attached to the softening resin and
sending them to the drain. After all the brine is drawn out of the brine tank, the system continues to slowly
rinse the mineral bed, giving plenty of time for all the resin beads to be recharged and rinsing out any excess
brine.
Fast Rinse Cycle
The valve then moves to its final regeneration cycle, in which water flows quickly through the bed in its
normal direction from top to bottom. This settles the mineral bed back down and serves as a final cleaning
rinse. The valve then returns home. The regeneration cycle is complete.
NOTE: The entire regeneration cycle, from backwash to fast rinse, takes one to two hours in most cases.

MANUAL REGENERATION:

Although it may never be necessary, you always have the option to start an immediate regeneration using the
"manual regeneration" key on the keypad. The manual regeneration will start with brine tank fill and a 2 hour
soak cycle as described above. Since a manual regeneration is primarily intended to recover from unusual
circumstances, such as allowing the brine tank to run out of salt, it is assumed that you need to recover full
capacity. Therefore, a manual regeneration always uses the maximum salt dose for your size of unit.
