CYCLE 4: Brine Draw / Slow Rinse
Now that the system has completed cycle 3 and backwashed for the
set time, the valve moves to the brine draw position. In this position,
the valve creates a vacuum to pull the brine solution out of the brine
tank. The brine solution flows down slowly through the mineral bed.
This is the ion exchange process, when the hardness ions that have
attached to the softening resin exchange with the positively charged
sodium ions from the brine solution and sending the hardness ions to
the drain. After all the brine is drawn out of the brine tank, the system
continues to slowly rinse the mineral bed, allowing time for all the
resin beads to be recharged and rinse out any excess brine.
CYCLE 5: Fast Rinse
With the brine solution fully rinsed out, the valve then moves to its
final regeneration process cycle 5. Water flows top to bottom, quickly
flowing water through the bed for a final fast rinse. This settles the
mineral bed back down and serves as a final cleaning rinse. Upon
completion of cycle 5, the valve will return to the home position
ending the regeneration process.
NOTE: The entire regeneration cycle, from backwash to fast rinse,
takes one to two hours in most cases.
When to use the Manual Regeneration Option:
The EC4 Control has a manual regeneration mode available “Regen
Now.” See the “How to Initiate a Manual Regeneration” in this
manual on how start a manual regeneration. An example of when
to use a manual regeneration would be if you ran out of salt in your
brine tank and hard water is flowing in your home. Fill the brine tank
with Salt (See Add Salt to Brine Tank in the manual) then run a
manual regen, or schedule one for later in the evening to complete a
full regeneration of your system.
EC4 Display / Home Screen
The EC4 Display / Home Screen displays the current conditions of
your EC4 System. Press any button to turn on the display light. The
normal operation of the display will scroll between the following
information:
• Day of the Week, current Date, and Time.
• Capacity Remaining Bar and % Remaining: This bar indicates
the percent of capacity the softening media has remaining to
treat your homes water. When the set capacity setting is exceeded
(Default 7o%), the Softener will schedule a regen for the next
scheduled regen time.
• System Status: Normal or Alarm, Alarm will indicate current
Alarm situation will be identified on screen. Press any button on
display when Audible alarm is active to postpone alarm.
• Current Water Flow: This will only be show when water is
flowing through the outlet of the valve and an alarm is not active.
• Regen Scheduled: This will display only if a regen is triggered to
occur, displaying the time scheduled regeneration time. Regen
scheduled will replace the Capacity Bar.
