Hardness in grains per gallon (GPG). Divide hard-
ness in ppm or mg/L by 17.1 to get GPG. If you have
iron or manganese, add 4 for each ppm.

Step 5d: Setting the Time
The display will show the time as currently programmed in the system. It can be adjusted by
simply pressing the UP or DOWN button repeatedly, holding down a button will cause time
to change quickly. You can press the Extra Cycle button to confirm the setting, or just leave it
alone for a few seconds and it will save.
Step 5e: MASTER Programming
The MASTER programming section contains ALL of the
available settings, including the settings shown in
USER programming. These settings (with the excep-
tion of the Capacity and Brine Fill settings) typically
use the default values and should not need adjusted.
MASTER Programming Settings
To enter master programming, use the UP or DOWN button to set the time of day to 12:01
PM and press the Extra Cycle button to confirm the time setting. Then press BOTH the UP
and DOWN buttons at the same time and hold for 5-10 seconds until the Parameter Display
shows DF. Adjust each setting with the UP/DOWN buttons if necessary, then press the Extra
Cycle button to advance to the next setting.
The time MUST be set to 12:01PM (PM indicator shown). If you do not get the DF
parameter, it is possible the time changed or was not set correctly. Press the extra cycle
button to get back to the time of day and try again.
The settings shown are the only ones that MAY need adjusted. If a setting is not listed in
this chart, DO NOT CHANGE IT without consulting with an expert.
Continue pressing the Extra Cycle button until you get back to the time of day to save
your settings, or press nothing for 5 minutes to discard any changes
The time will need to be
changed from the current time for

You WILL need to adjust your
capacity setting.
DO NOT change any settings unless indicated here or directed to do so by an AFWFilters
support technician. Other videos and instructions are not designed for AFWFilters systems
and may lead to improper operation. If you change a setting in the MASTER programming
that is not shown below use the system reset section to reset the system to defaults and
adjust ONLY the settings shown below and in the USER programming section.
