Your chem free iron filter requires some minor maintenance to ensure optimum performance and years of trouble-free clean
water. The following steps should be performed once or twice a year (more often under harsh conditions):
1.
Verify the pumping rate of the system - do not refer to pumping curve for this data. Follow the instructions found on
Page 3. If the measured pumping rate is less than the backwash rate of the filter, see Page 12, Trouble Shooting.
2.
Have your water tested - for pH, iron and manganese on both the treated and raw water to ensure your water
conditions haven't changed.
3.
Inspect the hydrocharger and the piping between the iron filter and the pressure tank to ensure they are not plugged
with raw iron. If the line becomes plugged, the flow of water to the home will be reduced. This will result in a reduction
of water available for backwashing the unit which will inhibit operation of the system.
4.
Air-to-water pressure tank - periodically drain and flush your tank to prevent a build-up of precipitated iron from forming
in the bottom of the tank.
5.
Bladder tank - periodically check that the bladder air pressure remains at 2 psi lower than the cut-in pressure of your
pump.
6.
Check the hydrocharger - to ensure it is drawing air properly and for the correct amount of time (1/3 of the pump cycle
time or 20 seconds, whichever is greater).
7.
For applications with low pH, manganese or hydrogen sulfide, consult your local dealer for specific instructions to
maintain the efficiency and operation of your filter.
8.
Periodic cleaning of the air vent assembly with mild acid or vinegar will ensure that it continues to vent excess air
properly.
9.
The filter tank can be cleaned with a mild soap solution.
10.
Never subject the unit to freezing.
