How To Set Regeneration Cycle Program

How to set the regeneration
cycle program.
The regeneration cycle program on your Iron Curtain Filter
has been factory preset, however, portions of the cycle
or
program may be lengthened or shortened to suit local
conditions.
To expose cycle program wheel, grasp timer in upper left-
hand corner and pull, releasing snap retainer, and swing
timer to the right.
To change the regeneration cycle program, the program
wheel must be removed. Make sure the timer is in the service
position and then unplug the power cord. Grasp program
wheel and squeeze protruding lugs toward center of wheel.
Lift program wheel off timer. (The arm on the program
actuator switch may need to be moved to facilitate removal.)
After making the necessary adjustments described in steps
2, 3, and 4, install the program wheel on the timer. Place
program wheel over the protruding lugs and gently push
program wheel on until the tabs on the lugs are snapped in
place over the wheel. (The arm on the program actuator
switch may need to be moved to facilitate installation.)
Return timer to closed position engaging snap retainer in
back plate. Make certain all electrical wires are located above
snap retainer post. Plug in power cord.
The program wheel as shown in the drawing is in the service
position. As you look at the numbered side of the program
wheel, the group of pins starting at 10 determines the length
of time that your Iron Curtain Filter will backwash.
For example: If there are six pins in this section, the time of
the backwash will be 12 minutes (2 minutes per pin).
To lengthen backwash time, remove 1" long roll pin(s) from
pin storage on timer (1 pin needed for each 2 minutes to be
added). Beginning at number 8 and counting back, remove
pin(s) extended out back of program wheel (1 pin for each
long roll pin to be added to extend backwash time). Replace
with long roll pin(s) so it extends out back equal distance with
existing pins. IMPORTANT: After installing long roll pin(s),
turn the manual regeneration knob clockwise one revolution
to make sure long roll pin(s) do not touch drive gear (Item 22,
Figure 7, page 13).

How to change the length of
air recharge cycle (ARC).
The group of holes between the last pin in the backwash
section and the second group of pins determines the length
of time that your Iron Curtain Filter is in the air recharge cycle
rinse (2 minutes per hole). Note: This cycle also uses the
set of pins on the backside of the program wheel simul-
taneously with the first set of spaces on the front side of
the program wheel.
(Refer to page 3 for factory settings)
To lengthen the air recharge time, remove 1" long roll pin(s)
from pin storage on timer (1 pin needed for each 2 minutes
to be added). Beginning at number 10 and counting up,
remove pin(s) (1 pin for each long roll pin to be added to
extend air recharge time). Replace with long roll pin(s) so it
extends out back equal distance with existing pins. For each
long roll pin added, move the rapid rinse pin to the higher
numbered end of wheel.
After the rapid rinse pins, leave two holes then place two pins.
IMPORTANT: After installing long roll pin(s), turn the manual
regeneration knob clockwise one revolution to make sure
long roll pin(s) do not touch drive gear (Item 22, Figure 7,
page 13).

How to change the length of
rapid rinse time.
The second group of pins on the number side of the program
wheel determines the length of time that your Iron Curtain
Filter will rapid rinse (2 minutes per pin). To lengthen the rapid
rinse time, add pins at the higher numbered end of this
section as required. After the rapid rinse pins, leave two
holes then place two pins.
The regeneration cycle is complete when the program actua-
tor microswitch drops off the last pin. The program wheel
however, will continue to rotate until the homing microswitch
drops into the notch on the program wheel.
