Operating Conditions
Water Heater
If the water heater has been exposed to both iron and hardness for a long period of time, replacement of the heater tank
maybe the only practical solution to prevent continued staining originating from this source. After completing the installa-
tion of the chemical free iron filter system, clean the water heater by following these instructions:
1. Shut off energy supply to water heater and close heater inlet water valve.
2. Drain hot water tank completely. Open inlet water valve allowing heater tank to be refilled with iron-free water. Continue
flushing until water runs clear to drain.
3. If, after approximately 30 minutes flushing, water does NOT clear, terminate flushing operation. Refill hot water heater with
water and pour approximately 1/2 gallon of household bleach into top of heater tank. Allow bleach solution to stand in
tank for 20 to 30 minutes. Flush tank again until water is clear at drain. Turn energy supply on.
NOTE:
If water does not clear in approximately 10 minutes, water heater should probably be replaced.
Dishwasher
Consult owners’ handbook and follow manufacturer’s instructions.
Toilet Flush Tanks
Prior to commencing installation of the filter system, pour 4 to 6 ounces of resin mineral cleaner Pro-Rust Out or inhibited
muriatic acid into flush tanks and bowls and let stand. When installation is completed, flush toilets several times with iron-free
water. If iron deposits or stains remain, repeat procedure until clear.
Maintenance Instructions
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 a pumping curve for this data. Follow the instructions found on
page 7. If the measured pumping rate is less than the backwash rate of the filter, see page 39, Trouble Shooting.
2. Have your water tested - for pH, iron and manganese on both the treated and raw water to ensure your water condi-
tions 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.
