3. Remove the control valve from the box and make sure the large black O-ring is seated in its place on the base just above the threads. Hold it over the top of the Hercules Filter and align it with the opening. Center the riser tube to the valve and carefully slide it on. You may need to push down hard to get the tube to slide all the way in. There is an O-ring in the valve. Once it is in, carefully start turning the valve clockwise to thread it down tight. Make sure there is no grit in threads to ensure proper seal. Do not cross thread or over tighten.

4. Plumb it in by cutting the cold water line where you want to connect - the raw water side. Connect your incoming water line to the shut-off on the inlet side of the control valve. Connect to the shut-off valve on the outlet of the small filter housing to the other portion of the pipe leading to the house (the filtered water side).

5. Next, a backwash drain line (1/2-inch plastic hose that you must supply) must be attached to the drain fitting on the back of the control valve and run into a drain. (Read control valve manual for more instructions)

6. Once all filters are plumbed in, you need to backwash ALL filters to flush out media dust. There may be a lot of fine media dust in the filters that will flush out when the water is first turned back on. Before backwashing & flushing in the next step, take the filter cartridge out of small housing, so it doesn’t plug up. First, close the ball valve after the small 10-inch cartridge filter housing. This is the filtered water going into the house.

7. On the Hercules Filter, set the control to the backwash position (check the control valve manual). Unplug the control.
Important! Open valve partially to let tank fill very slowly in backwash position. This will allow air to escape out of the drain as the tank fills. Doing otherwise can cause control valve to plug up with media and cause enormous problems. Turn the filtered side water line off. This will keep the dust out of house plumbing, hot water heater, etc.

8. Important! First remove the one-micron filter from housing so it will not plug up.

9. Then Arsenic-Fluoride Filter & Purification Filter has to be flushed. A spigot is provided for a hose; run hose to a drain until water is clear.
If water will be off for some time, it would be a good idea to shut the power off to the hot water heater unless the water line is on bypass so the client has continuous water flow.
Caution! You may need to turn off power to hot water heater until you are done. Hot water can expand.
Low water can burn out electric heating elements if it is on and the water level is down.

10. Note: The water will have a little bit of grayness or air bubbles coming out for a few days. This is harmless. If you fill a clear glass, you will see bubbles rise to the top and leave the water crystal clear & odor free. If not, run water until clear and repeat air bubble test in glass.

11. Set backwash pins in control valve as needed. (Check control valve manual). All pins in = every night. Every other pin = alternate nights, etc.
If you don't know how often to set it, email me telling your water conditions before installing the system, and I will be happy to suggest the right setting.

12. Set clock time to current time. Do not worry about backwashing at night. It is automatically off set when set to current time. (Check control valve manual).

13. Replace 1-micron filter cartridge in housing (post filter) every 12 months or when water flow noticeably slows down.
How to replace: Shut off ball valve before the filter and after the filter. Open the post bib enough to relieve pressure. It's going to drip and squirt some water. When you unscrew the filter housing, it's going to be full of water, so have a bucket underneath. Now you can rinse out the cartridge housing and put new filter in the housing.

14. For troubleshooting, check control valve manual.
