DO NOT INITIATE A REGENERTION OF THIS SYSTEM FOR A
MINIMUM OF 24 HOURS AFTER ADDING THE WATER TO
ALLOW ADEQUATE PRE-SOAKING – BACKWASHING BEFORE
THE MEDIA IS SATURATED WILL CAUSE A LOSS OF MEDIA
AND POTENTIAL DAMAGE TO THE CONTROL VALVE.
Attach the upper locking stack diffuser onto the underside of the
control valve. Be sure to twist and lock into place.
Lubricate the tank O-ring seal. Note: Only use silicone lubricant.
The Fleck 2510SXT control valve (head) can now be secured to
the top of the tank. Before attaching the valve, check to make sure
that there is no debris such as gravel or media in the tank threads.
Screw the control valve onto the tank – make sure that the riser tube
inserts into the center hole in the upper stack diffuser and the control
valve as you screw down the valve. The control valve should be
hand-tightened (clockwise). Do not use the control valve's timer
assembly for leverage and do not use tools. A firm grasp with both
hands at the base of the valve will work. Do NOT use pipe cement
(“pipe dope”) or Teflon tape on the threads.
Step 4. – Turn off the Water & Electric Water Heaters
Turn off the household main water shutoff valve. Open all plumbing fixtures inside the home as
well as the outside faucets to drain as much water out of the plumbing system as possible.
If you have a conventional electric water heater or an on-demand (tankless) electric water heater,
we highly recommend that you turn off the electricity to the heater while installing any water
treatment equipment. Following completion of the entire installation, restore the water flow by
turning on the household main water valve and allow all air to be purged from the plumbing system
before turning the power back on to your water heater.
Failure to follow this procedure could result
in serious, permanent damage to the heating elements in your water heater.
Step 5. – Prepare and Install Inlet and Outlet Plumbing Connections
Teflon

tape is the only sealant to be used on the bypass and drain fittings.
A bypass assembly is included with your system. Depending on the size of your Iron Rival, the
bypass will generally have ¾” or 1” NPT threaded fittings to connect to your main incoming and
outgoing water lines. You will need to purchase the appropriate NPT threaded fittings to connect to
the material and size of your main water line (inlet and outlet). Locate the inlet and outlet ports on
the back of the Fleck 2510SXT control valve. Note that the inlet and outlet are marked with arrows
indicating the correct direction of water flow. When you are looking at the back of the control
valve, the inlet is on the left and the outlet is on the right. A brass check valve is pre-installed on
