Lubricate the by-pass valve o-rings only on the pipe connectors with some vegetable oil or silicone
grease and connect the bypass assembly to the Fleck 5600-SXT control by sliding the bypass valve
firmly into the body of the Fleck 5600-SXT. Once bypass is in far enough, you will be able to easily
insert the red connector clips. DO NOT USE OIL OR PETROLEUM GREASE ON ANY PART OF THE FLECK
5600-SXT CONTROL VALVE. O-rings are OK to lubricate but not the main tank threads.
9.
Make sure the by-pass valve is in the bypass position when starting the installation. Follow the IN
and OUT arrows on the bypass valve and control valve for proper connection of in and out water
piping. Leave in the BY-PASS position for now.
10.
Now install your water pipes to the Fleck 5600-SXT bypass end connectors. Our preferred method is
to wrap the pipe threads with 2 or 3 wraps of Teflon tape, then apply a thin coating of white non-
hardening Teflon joint compound paste (available at all hardware stores) before attaching the pipe
fittings. Make sure inlet is installed to the 'In" pipe connector on the bypass valve and outlet is on the
“Out” connector.
Note:
Arrows on bypass valve should be visible from the top of the bypass valve.
11.
Connect some flexible tubing from the drain connection on the Fleck 5600-SXT control valve to a
suitable drain such as a septic tank or drain to a sewer. It is OK to run the drain line up and over the
Fleck 5600-SXT Softener up to 4 feet above the top of the tank. If the drain line will be more than 20
feet, and especially if your system is a 2.0 or 2.5 cubic foot size, use larger diameter tubing such as ¾”
or 1”. Note that it is desirable to be able to run the drain line into a bucket in order to test the
backwash flow rate in the future. This is why hard piping the drain line is discouraged, however, if
you do use hard PVC piping for the drain line, and you are able to remove the hard PVC drain piping
and attach flexible tubing should you ever desire for testing purposes, it is OK to use rigid PVC pipe for
the drain. Make sure the drain tubing is firmly clamped to the barbed fitting with a hose clamp to
prevent leaks.

Next, connect the solution tank to the Fleck 5600-SXT control valve with the black tubing, provided
with the brine tank.
