Open a nearby cold water high demand tap, then open
the Outlet Valve. This will prevent antifreeze from spreading
throughout the piping system. Run the tap for 30 minutes.
Open all other cold water taps in the home and flush
separately for 1 minute each.

Close the Inlet Valve and Outlet Valve. Partially drain the
System using the Manual Flush function for 1 minute to
depressurize the System. Refer to the Controller Functions
section under D. OPERATIONS on how to perform a Manual
Flush sequence. Remove the Plug from the Mini Ball Valve on
the Inlet Fitting Assembly by depressing the lock ring and
pulling on the Plug. Slowly open the Mini Ball Valve to ensure
there is no pressure in the System. Water will flow out, but
should not spray. Close the Mini Ball Valve immediately. If
there is spray, repeat the Manual Flush sequence. Replace the
Plug in the Mini Ball Valve.

Be sure the water level in the System is 2” above the
bottom of the Prefilter cavity. Add more water by slowly
opening the Inlet Valve if necessary. Add 2 cups (500 ml) of
unscented household bleach (5 - 6% chlorine) or 1 cup (250 ml)
chlorine bleach (12% chlorine), maximum 3 months old, to the
System.
8
Allow the System to soak for 15 minutes. With the
System Cap tightened, drain the System using the Controller.
Open the Inlet Valve and allow System to pressurize.
NOTE: If the winterization spring start up is combined with the
annual maintenance cleaning procedure, the System must
soak for 60 minutes. If the System is on ground or well water,
the System must be cleaned with citric acid crystals instead
of chlorine bleach. Follow the directions on the package for
preparing the citric acid crystals. Never mix chlorine bleach
with the citric acid crystals.
9
Open the Outlet Valve and a nearby COLD water tap to
remove chlorine from the System. Run the tap fully open for 5
minutes. Further flushing must be performed by the
homeowner.
10
Close the Inlet Valve and Outlet Valve. Use the Controller
to depressurize the System. Ensure that there is no pressure
inside the System as described in Step 5.
11
Open the System Cap and install a new Carbon Prefilter.
If using a Stainless Steel Prefilter, insert a clean, undamaged
Stainless Steel Prefilter and replace the System Cap.
Do not remove the Thimble
Filter from the spigot. If the
Thimble Filter is dislodged,
gently push it back down into
the spigot. If the Thimble Filter
is damaged, replace with a
new Thimble Filter.
