Close the Inlet and Outlet Valves. Using the Controller,
initiate a Manual Flush sequence to bring System pressure
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.
FIGURE 7
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.

For Ground Water Systems, refer to Ground Water
Application Cleaning Procedures section before beginning
this step.
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.
Horizontally-mounted Systems:
With the Internal Prefilter still removed, unscrew the
½
”
Brass
Plug on the Air Vent Assembly near the System Cap.

Brass Plug
Pour 2 cups (500 ml) of 5 - 6% unscented household chlorine
bleach OR 1 cup (250 ml) of 12% chlorine bleach into the
System Casing cavity. A funnel may be used in this step to
assist pouring. Replace the ½” Brass Plug. Slowly open the
Inlet Valve to pressurize the System. Let stand for 60 minutes.

Using the Controller, activate the Manual Flush
sequence. Refer to the instructions in the Controller Functions
section under D. OPERATIONS on how to perform a Manual
Flush sequence. Once the flushing is complete, open the Outlet
Valve and a nearby COLD water tap to flush most of the
chlorine from the System. Run the tap fully open for at least 60
minutes.
NOTE: Use only COLD water taps and continue the flow of
water until there is no chlorine smell.
