Filter System Normal Operation
•
The normal display alternates between time of day and days until regeneration.
•
Days remaining until the next regeneration will count down from the regeneration day
override value to 1 day remaining. Regeneration will start next scheduled regen time.
Battery Back-up (9 Volt Battery Required)
Attach a 9v battery to its cable. The battery lays on bottom plate of the valve, below
circuit board assembly.
DO NOT INSTALL BATTERY UNTIL AFTER INITIAL BACKWASH.
The purpose of the battery is to hold the clock time during a power outage (all other
values are stored on the circuit board) and to advance the valve to a cycle step that will
not allow water to run to drain, if the power failure occurs during a backwash cycle.
How to Start A Manual Backwash
1.
If days remaining is not already at 1 press and hold the Set/Change button. After 7
seconds the days remaining display will read: [1]
2.
With days remaining at 1 press and hold the Set/Change button again. After 5 seconds
the regeneration cycle will begin.
3.
Fast Cycling Through each Step
: First complete above immediate cycle steps; Press and
hold the Set/Change button. After 3 seconds valve will start to advance to next step.
When to Add Potassium Permanganate
Add one 5-lb jug of potassium permanganate every 3 - 4 months. Check the potassium
permanganate solution tank and when you see the mound of potassium permanganate
disappear after a few months, just add another 5-lb jug.
In some cases, you won’t see the mound; you might just see solution after a couple of
weeks. If you have it set to regenerate (backwash cycles) every 1 – 3 days, you might
need to add it more frequently, perhaps every 2 months.
