Care of Your Filter
To retain the attractive appearance of your new water filter, clean occasionally with a mild soap solution. Do not use
abrasive cleaners, ammonia or solvents. Never subject your softener to freezing or to temperatures above 43°C (110°F).

Please refer to the servicing section of this manual for step by step procedure.
Not following the above will void all warranty on the control valve.
Maintenance of your new water filter requires very little time or effort but it is essential. Regular maintenance will ensure
many years of efficient and trouble free operation.
Replacing Media Bed
The media bed in a neutralizing filter is slowly dissolved and has to be replaced. The frequency of replacement varies,
depending on water quality - consult your dealer to determine the expected life of your media bed.

Backwashing Instructions
To Calculate Backwash Frequency - Normal Applications
Backwash frequency for households with average water use can be determined using the following guide. The guide
cannot be used if the filtered water supplies a swimming pool, geothermal pump, outside spigots or other high water
demand devices or activities. If your application includes any of the foregoing refer to the paragraph on “Special
Applications” below.
1. Locate the box intersected by the number
of people in your family and the parts per
million (ppm) of iron in your water (if your
ppm is between two numbers on the guide,
use the higher number).
2. The number in the box represents how many
times your filter has to backwash in a twelve
day schedule.
Example: You have four in the family and 8 ppm of iron. Refer to the guide and locate the box intersected by four in the
family and 8 ppm of iron. The figure supplied is 2. This means your filter control should be programmed to backwash twice
in twelve days — that is every sixth day. If the figure had been 3 it would mean 3 backwashes in twelve days or every
fourth day.
To Calculate Backwash Frequency - Special Applications
To ensure adequate reserve capacity and prevent loss of water pressure between backwashes the figure of 15,000 (not
the full 30,000 ppm capacity) is used to calculate backwash frequency. Determine your backwash frequency as follows:
