Section 4: BACKWASHING INSTRUCTIONS
Periodic regeneration of the iron and manganese reduction system bed is required to fl ush out the entrapped iron that has accumulated. This procedure is performed
automatically at 1:00 a.m. for a period of approximately 10 minutes and will not interfere with a softener regeneration, which is usually set for 2:00 a.m.
TO SET BACKWASH FREQUENCY FOR NORMAL HOUSEHOLD APPLICATIONS:
To determine and set Backwash Frequency, follow these instructions:
1)
Select Backwash Frequency Schedule corresponding to your model (page 3-6 and 3-7).
2)
Locate box intersected by number of persons in your family and iron content of water (if iron concentration is between two numbers in Schedule,
use higher number.)
3)
Number in box represents number of days, between regenerations. Refer to How to Set Time of Regeneration and Days Between Regeneration on page
3-9.
Example: You have model APIF100, 4 people in family, and 8 ppm iron. Refer to Schedule for model APIF100 and locate box intersected by 4 in family and 8 ppm iron. The
fi gure indicates 6 as the the number of days between each regeneration period.
IMPORTANT NOTE
The Backwashing Frequency Schedules are based on average water consumption rates and are merely guides. They are NOT intended to be used if
water is used by outside spigots, a swimming pool, geothermal heat pump, or other high water usage devices or activities.
