The control valve manufacturer's instructions are enclosed with the unit, but here's a brief “everything-you-need-to-know” version. The control valve manufacturer's instructions apply mainly to water softeners, but you should keep the manual as a parts reference.
When the filter is in the place where it will be installed, load the Centaur media into the tank. To do this, cover the hole in the center tube of the filter with tape or a plastic bag to keep media out. Then pour all the Centaur media into the tank. Avoid breathing the dust from the Centaur as you pour. No gravel underbed is needed with the Vortech tank. The Centaur will fill the tank only about 2/3 full. This is the correct amount.
Remove the protective cap or tape from the center tube, clean away the carbon dust from the top of the tank, then screw the control valve onto the top of the tank, making sure that the center tube goes into the center hole in the bottom of the filter valve. It's like putting a cap on a bottle. The valve's o-ring is pre-lubricated. Do not use excessive force in tightening, and no tools are needed. Hand tight and snug is good enough.
Attach the metal bypass valve to the back of the filter valve using the clips that are on the valve. Refer to a picture in the manual if there are questions about placement. Again, don't over-tighten. There will be a bit of up and down play in the installed bypass. This is normal. It's there to give the installer some room for error.
Attach the filter to the home plumbing using the 1" female fittings on the bypass valve. Note that the “In” port of the valve is on the left as you look at the filter from the back.
Connect the unit to an approved drain. The drain line attaches to the barbed drain fitting on the side of the control valve. (See picture.)
When the unit is connected, with the control valve and the bypass valve in the “Service” position, open a faucet downstream and turn the inlet valve on part way to allow water to flow into the filter slowly. Check for leaks.
It's best to let water run very slowly through the filter to allow the bed to soak and to minimize media being washed out. (The manufacturer of the filter carbon recommends a 24-hour soak before putting the filter in service. We've found that this is usually unnecessary, but it's best to avoid high volume use for the first day or so.) Allow the filter to rinse for at least ten minutes through the open faucet, gradually increasing the inlet volume, then close the faucet and the filter is in service.
The control valve is usually programmed before shipping. But, check to see that pin 12 is pulled out on the skipper wheel. This will provide a backwash every 12th day only. If alternate programming is desired, consult the manufacturer's instructions. For most clean, city water usage, a once in twelve days backwash schedule is fine.
When using the Fleck instructions enclosed, keep in mind that most of the information pertains to water softeners. What you have is a filter, not a water softener.
The Fleck instructions have no specific information about filters, but keep the manual as a source of information in the event that you need parts for the valve.
After the filter is installed, the valve is pre-programmed and needs no alteration. All you need to do is set the time of day as per instructions in the manual, plug the valve in, be sure it's in the service position, then forget it. Operation is completely automatic from that point.
