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
.
Determining The Backwash Frequency
The following table can be used to help determine the frequency of regeneration.
Use this table as a guide - individual circumstances will require more or less
frequent regenerations.
To set a neutralizing filter follow the table under mild conditions.
NOTE: add one person if you have a dishwasher.
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 twelfth day, according to your
requirements.
The control is shipped with the skipper wheel tabs pushed
outwards. You must push the tabs in toward the center
of the wheel (retracting the trip finger) 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. This slight movement of the manual regeneration knob engages the program wheel and
starts the regeneration process. The back center knob will make one revolution in approximately three hours and stop in the position
shown in the drawing. Actual backwash time is 14 minutes. In any event, treated water may be drawn after rinse water stops flowing
from the filter’s drain line.
