Adding Media & Installation Instructions
1.
Unscrew by hand the Fleck 9100 control valve from top of the tanks if it was shipped screwed
on. Place distributor tubes in tank if not already inside tanks. If not already done, make sure
blue cap is on top of distributor tubes, or wrap the top of distributor tubes with electrical or
duct tape. The idea is we do not want gravel or resin to go down the distributor tube when you
are adding media.
2.
Add filter gravel supplied first, using the funnel sent with the nitrate filter dividing gravel equally
between tanks.
3.
Next add nitrate filter resin media. Tank will be approximately 2/3
4.
Remove cap or tape from top of distributor tube. Be careful not to pull up distributor tube
when removing cap or tape.
to the 3/4 full. Divide resin
provide equally between tanks.
5.
If possible at this point, fill tank completely with water. This will allow the nitrate filter resin to
settle and eliminate the need of “purging” the air out of the tank later.
6.
Add a small amount of vegetable cooking oil to the tank threads and screw on Fleck 9100
control valve carefully. Alternatively you can use silicone grease, but do not use pipe-joint
compound, Teflon tape, or Vaseline or other petroleum greases to lubricate tank threads.
7.
See how the Fleck by-pass is connected. There is an in and out arrows on the bypass valve for
the inlet and outlet pipe. Install inlet and outlet piping, drain tubing and brine line tubing. The
brine line tube is included and is shipped inside the brine tank.
8.
Note that the over-flow fitting on the side of the brine tank does not need to be connected,
unless the nitrate filter is installed in a closet or somewhere where overflowing salt water could
cause a problem. Water rarely overflows the brine tank however.
9.
Add approximately 5 gallons of water to brine tank, then fill brine tank with salt, about 300 lbs,
or 6 50-lb bags. It is OK to use any kind of water softening salt; however we find that extra
coarse salt works better than the pellets. You do not have to add water to the brine tank again
after this first time during the start-up.
10.
Close the valve after the nitrate filter. Connect a garden hose to the hose bib after the nitrate
filter and open hose bib. Turn on the water to the nitrate filter and allow the water to run out
the garden hose until the water is clear.
11.
See the Fleck 9100 Service Manual for instructions on how to program and set nitrate filter.
Your Fleck 9100 is already programmed for the size tank you have, but you do need to set the
