Select a location for installation of your Iron Rival that is within close proximity to the main
incoming water lines of the home. The location should have a firm, level surface with sufficient
space for the treatment tank. Ensure that there will be sufficient space surrounding the unit to
facilitate maintenance.
You will also need access to a standard, non-switched, grounded 120volt (60 Hz) electrical outlet.
The Fleck 2510SXT control valve comes with a 5 foot long electrical cord. An extension cord may
be used to reach a suitable electrical outlet. If this option is used, ensure that the extension cord is
UL/CSA certified and of an appropriate wire gauge for the application.
You will also require a nearby floor drain or standpipe to discharge the drain water from the
backwash cycle (a drain standpipe for a washing machine, floor drain, or sump pump are excellent
drain options). We recommend that the drain line be connected to a minimum 1½" drain standpipe
or floor drain located ideally below the top of the head of your Iron Rival. If possible, the drain
should be no farther than 20 feet from the system.
Note: Never connect the drain line directly into a drain pipe. Allow an air gap between the drain
tubing and waste line to prevent the possibility of back-siphoning. We do not recommend use of a
check valve as it may become clogged with contaminants ejected from the system during backwash.
Step 3. –Prepare Treatment Tank
Two types of media are supplied with your Iron Rival system: washed gravel which forms the base
layer (underbedding) in your treatment tank, and specialized catalyst media (either Birm or Filox-R
depending on the model purchased), that promotes the rapid oxidation of the contaminants.
Before you start, gather the main treatment tank, the Fleck 2510SXT control valve, upper locking
stack diffuser, distributor and riser tube assembly (shipped inside the tank), funnel, and the bags or
boxes of gravel and catalyst media. Place the tank in the location where it will sit when the
installation is complete. Temporarily, remove the riser/tube distributor assembly from the treatment
tank. Hand tighten the Fleck 2510SXT control valve on the tank, and mark where the front of the
tank will be. Turn the tank so that the front of the tank is where you want it when it is full –once it
is full of media and water, it becomes very heavy and is hard to move!
Remove the controller and re-insert the distributor and riser tube assembly into the tank. The
distributor, which looks like a plastic screen, is pre-connected to the end of the long plastic riser
tube which extends from the bottom of the tank to the top of the tank where the control valve is
attached. At the bottom of the tank, there is a recess in the center of the tank to accept the
distributor to keep it aligned properly in the center of the tank. The riser tube has been pre-cut to
the correct height for you. When the distributor is correctly positioned, the top of the riser tube will
be almost perfectly flush with the top of the tank. If the tube is protruding above the tank, the
distributor tube is not nested correctly in the recess at the bottom of the tank.
Add enough water to the tank to cover the lower distributor with a minimum of 6 inches of water.
This will prevent damage to the lower distributor as gravel is loaded. Place the funnel into the tank
so that the riser tube is in the middle. Place tape over the open end of the riser tube. This will
prevent gravel or media from accidentally going down the tube during the following steps.
