Close the Inlet and Outlet Valves. Using the
Controller, initiate a Manual Flush sequence to bring
System pressure to close to zero. Refer to the
instructions in the Controller Functions section under D.
OPERATIONS on how to perform a Manual Flush
sequence. 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. Reinsert the Plug into the Mini Ball Valve.

Vertical Systems:
Remove the System Cap using the Cap Wrench. The
water level should be at least 2" above the Internal
Prefilter spigot.
If the water level is below 2", open the Inlet Valve slowly
to raise the water level.

Once the cap is removed, wipe the System Cap out with
a clean, soft cloth, remove the O-ring carefully, wipe the
O-ring with a clean cloth, check the O-ring for damage or
wear, apply a very small amount of DOW CORNING 111
silicone lubricant on the O-ring, and replace the O-ring. If
necessary, replace the O-ring with a new O-ring.
Horizontally-mounted Systems: Ensure that there is still
some water inside the System after the Manual Flush. Do
not empty the System completely. If water stops coming
out during the Manual Flush, open the Inlet Valve slowly to
fill the System again.
WARNING!
Do not use a bottle of bleach more than 3 months
old.
If a Bypass Valve is installed, the Bypass Valve
should be closed for the entire procedure to avoid
contaminated water entering the household
distribution system. Contaminated water might
cause personal injury and in some cases death.
This cleaning procedure does NOT disinfect the
household pipes. If potentially microbiologically
unsafe water is present in the pipes, it is strongly
recommended that all pipes be sanitized.

Vertical Systems:
With the Internal Prefilter still removed, pour 2 cups
(500 ml) of 5 - 6% unscented household chlorine bleach
OR 1 cup (250 ml) of 12% chlorine bleach into the
Prefilter cavity. Replace the System Cap. Slowly open the
Inlet Valve to pressurize the System. Let stand for 60
minutes.
