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 conditions
haven’t changed.
3. Inspect the Control Valve 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. 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.
7. Periodic cleaning of the air vent assembly with mild acid
or vinegar will ensure that it continues to vent excess air
properly.
8. The filter tank can be cleaned with a mild soap solution.
9. Never subject the unit to freezing
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 filter to
freezing or to temperatures above 43°C (110°F).
SERVICING COMPONENTS
-
The seals and cartridge should be inspected/cleaned or
replaced every year depending on the inlet water quality
and water usage.
The media should be replenished or replaced depending
of inlet water quality and water consumption. Check with
your water treatment expert on the media bed change
frequency.
BELOW ARE SOME GUIDELINES:
Piston assembly, seal and spacers, injectors should be
replaced on an annual basis.
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 Model NU 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.
NU - 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.
TO - under normal operating conditions the effective life of the
filter media is approximately one to three years depending
on the water quality, after which, taste and odor problems
may return. When this happens contact your dealer for a
replacement media bed.
MM / Nexsand - under normal operating conditions, the media
should never need to be replaced. If you experience pressure
loss and cannot correct it with a manual regeneration, your
media bed may need replacing - contact your dealer.
BM - Depending on the raw water iron content.

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):
