Programming Backwash Controls
Setting The 24-Hour Timer
Press and hold the red button in, to disengage the drive gear. Turn
the large dial until the actual time of day is opposite the time of day
pointer. Release the red button to re-engage the drive gear.
Setting The Backwash Frequency
The filter control features a skipper wheel with twelve numbered
tabs and trip fingers. Each represents one day of a twelve day
schedule. By adjusting the skipper wheel tabs the control can be
programmed to backwash every second, third, fourth, sixth or every
twelfth day, according to your requirements.
The control is shipped with all the skipper wheel tabs pushed out-
ward. You must push the tabs in toward the center of the wheel
(retracting the trip fingers) for each day that backwashing is not
required.
Rotate the skipper wheel until number “1” is at the pointer, leave this
tab out. Moving clockwise round the skipper wheel adjust the
remaining tabs using the following table as a guide.
MANUAL REGENERATION
Turn the manual regeneration knob clockwise. The slight movement of the manual regeneration now engages the pro-
gram wheel and starts the regeneration program. The back center knob will make one revolution approximately three
hours and stop in the position shown in the drawing. Actual backwash time is 14 minutes. In any event, iron-free water
may be drawn after rinse water stops flowing from the filter’s drain line.

PROBLEM
CAUSE
CORRECTION
1. Water is clear when drawn, turns
red upon standing (stain produc-
ing)
A.
Insufficient air drawn by Hydro-Charger.
B.
Bypass open or leaking.
C.
Filter bed overloaded with precipitated iron
due to insufficient backwash.
D.
Presence of manganese or tannins.
E.
Flow rate exercise for model.
F.
Check-valve located between Hydro-Charger
and pressure tank, disrupting water flow.
G.
Pumping cycle too short. pH of treated water
too low (should be 7.0 or higher; with man-
ganese, pH must be 8.2).
A. Check Hydro-Charger adjustment. If unable to
adjust for long enough draw, check pumping rate.
B.
Close bypass valve and/or repair as necessary.
C.
Upon correction of problem (increase backwash fre-
quency if problem determined to be insufficient fre-
quency), manually backwash until backwash water
starts to clear (in more severe iron-fouling cases, fil-
ter bed may need chemical cleaning - contact deal-
er).
D.
Recheck water analysis.
E.
Reread Sec. 2. Facts to Remember When
Planning Your Installation
F.
Relocate check-valve.
