How To Change The Length Of The Backwash
Time:
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 zero
determines the length of time your unit will backwash.
EXAMPLE: If there are six pins in this section, the time
of backwash will be 12 min (2 min. per pin). To change
the length of backwash time, add or remove pins as
required. The number of pins times two equals the
backwash time in minutes.
How To Change The Length Of Brine And Rinse
Time:
The group of holes between the last pin in the 1.
backwash section and the second group of pins
determines the length of time that your unit will
brine and rinse (2 min. per hole).
To change the length of brine and rinse time, move
2.
the rapid rinse group of pins to give more or fewer
holes in the brine and rinse section. Number of
holes times two equals brine and rinse time in
minutes.
How To Change The Length Of Rapid Rinse:
The second group of pins on the program wheel 1.
determines the length of time that your water
conditioner will rapid rinse (2 min. per pin).
To change the length of rapid rinse time, add or
2.
remove pins at the higher numbered end of this
section as required. The number of pins times two
equals the rapid rinse time in minutes.
How To Change The Length Of Brine Tank Refill
Time:
The second group of holes in the program wheel 1.
determines the length of time that your water
conditioner will refill the brine tank (2 min. per hole).
To change the length of refill time, move the two
2.
pins at the end of the second group of holes as
required.
The regeneration cycle is complete when the outer
3.
microswitch is tripped by the two pin set at end of
the brine tank refill section.
The program wheel, however, will continue to rotate
4.
until the inner micro-switch drops into the notch on
the program wheel.
