Carbon Filter Start Up Procedure
The water filter should be installed with the inlet, outlet, and drain connections made in
accordance with the manufacturer's recommendations, and to meet applicable plumbing
codes.
1. Push and hold the “extra cycle” button (far left button with triangle shaped arrows on the but-
ton). This button will advance the valve to the next cycle if it is pushed and released.
2. This will position the valve to backwash. You will see BW and four dashes. The four dashes
will change to a time value that will start to count down. Once the time begins to count
down. Slowly open the bypass valve to the service position. Ensure the drain line flow re-
mains steady for 10 minutes or until the water runs clear.
3. After the backwash cycle, the valve will move to the rapid rinse position. Check the drain line
flow, and run for 5-10 minutes or until the water runs clear.
4. The filter is now installed.
H2O2 Injection Setting
US Water Systems uses the “bubble method”. This is a visual method that works best for quick
and reliable H2O2 injection rates.
1. Set the proportional control on the Stenner injection panel (gray wall mount panel) to 40%
(there is a dial on the little black box (PCM) that the pump is plugged in to).
2. Run water for 10-15 minutes.
3. Take a sample after the carbon tank (or at a sink). The water in the sample container
(preferably glass) should be full of bubbles immediately after the sample is taken. If not the
installer will adjust the knob to 50%, run the water for 10-15 minutes and check again.
4. Continue adjusting the knob up in increments of 10% until the sample container is full of bub-
bles. Once the container is full of bubbles, it is an indicator that there is plenty of H2O2 in
the water.
5. Continue the same process decreasing the knob setting in 5% increments allowing the water
to run for 10-15 minutes between adjustments until there are just a few bubbles in the sam-
ple container (20-30 defined air bubbles) that come to the top of the water level and dissipate
immediately. This should be the optimal H2O2 injection setting.
This is an indicator that there is a small amount of residual H2O2 in the treated water and the contaminant
is being oxidized. Once this setting is determined the system will operate automatically.
Over the first 1-3 months it is important to monitor the H2O2 level in the storage/solution tank and start to
gain usage data that will help you determine the H2O2 usage and allow you to plan/order replenishment
H2O2 accordingly. This setting should be periodically checked and adjusted due to changes in the aqui-
fer (well) and loss of H2O2 concentration by degradation. After 6-8 months the H2O2 can lose concentra-
tion, so only replenish the tank to a level that can be used in 6-8 months to ensure the H2O2 concentration
strength is consistent.
