Installation
Refi ll Flow Control Assembly or Refi ll Port Plug
Control valves that are setup for backwash only come equipped with a refi ll port plug. The refi ll port plug has no regenerant line
connection.
Control valves that use a regenerant come equipped with a 3/8” refi ll fl ow control assembly. To switch to the ½” refi ll fl ow control
assembly, remove the refi ll fl ow control and retainer (from the 3/8” refi ll elbow) by twisting and pulling out. Insert the refi ll fl ow
control and retainer into the ½” refi ll elbow.
To complete the regenerant line connection, orientate the outlet in the desired direction and push the plastic insert into the polytube.
Push the polytube into the nut. Do not use pipe dope or other sealants on threads. The threads for the compression nut do not need
Tefl on tape. Tighten the nut securely to create a pressure tight connection. A pliers or crescent wrench may be used to tighten or
unscrew the nut. The nut, gripper and retainer sleeve is a 3 piece assembly that can come apart if removed from the elbow body.
Parts must be reassembled exactly as shown in refi ll fl ow control assembly drawing to function properly. If the nut is completely
removed from the body, slip the nut, plastic gripper and retainer sleeve on to the tube then tighten on to the fi tting.
Drain Line Flow Control and Fitting Assembly
To determine which drain line fl ow control to use, obtain media bed expansion tables from the media manufacturer, choose a water
temperature and look up the desired backwash rate per square foot of bed area. Then calculate the backwash rate using the desired
tank diameter. Using Table 7, choose the drain line fl ow control that has the backwash fl ow rate closest to the calculated backwash
rate. If a manufacturer chooses to use an external drain line fl ow control, use an elbow fi tting that does not contain a hole.
If the drain line is a 5/8” fl exible polytube, slide the nut onto the polytube, then place the polytube insert into the end of the polytube
and tighten the nut on to the ¾” drain line fi tting. The nut is only designed for use with fl exible polytube. Use other nuts if attaching
different materials.
To access the drain line fl ow control remove the locking clip by pulling it straight out. Pull fi tting out and replace the locking clip so
that it is not misplaced. The drain line fi tting is pressed in and has an o-ring seal.
In the ¾
”
elbow, the white fl ow control retainer is pressed in and has an o-ring seal. The retainer can be removed by rotating and
pulling. The fl ow control can be removed by prying upward with a small blade fl at screwdriver in one of the slots on the side. The
drain line fl ow control and retainer can be chemically cleaned in dilute sodium bisulfi te or vinegar, or replaced. Do not use a wire
brush to clean the fl ow control or the washer. The washers are identifi ed with three numbers, which correspond to the fl ow rate.
When reinstalling make sure the identifying number and the rounded inside diameter on the washer is visible when seated in the
retainer. The white fl ow control washer retainer can also be removed and cleaned. Push the retainer in fi rmly when reinstalling.
In the 1
”
straight fi tting, the retainer is the fi tting. Unscrew the nut to access the fl ow control. The drain line fl ow control and the
fi tting can be chemically cleaned or replaced. Do not use a wire brush to clean the fl ow control or the fi tting.
Do not use Vaseline, oils, or other unacceptable lubricants on o-rings. A silicone lubricant may be used on the black o-ring. Use a
pliers or crescent wrench to tighten or unscrew the nut. Do not use a pipe wrench to tighten or loosen nut. Do not use pipe dope
or other sealants on threads. Use Tefl on tape on the threads of the drain line control fi tting when installing ¾” NPT or 1” straight
fi tting.
