Pre-Installation
1.
Review your packing list and make sure you have received all the parts before beginning
installation.
2.
If you are going to be turning off the water to the house and you have an electric water heater,
shut off the power to the water heater before beginning installation in case water heater is
accidentially drained.
3.
Pick a suitable location for your filter system on a dry level spot where it won’t be exposed to
freezing temperatures. A minimum of 20 PSI is required. Maximum pressure is 90 PSI.
4.
Get all of your plumbing parts together before beginning installation. Installation typically takes
3 to 5 hours. However after installation the Nitrate filter must be allowed to run through a
complete backwash and rinse cycle (also called ‘regeneration’). You don’t have to be present
for this first backwash necessarily, but it does take 90 minutes.
5.
After the system is installed and running, you may notice sediment or color in your water. This
occurs when sediment that is has been in the pipes for years is dislodged by the soft water or by
the simple act of turning the water pressur on and off to the house. This rarely lasts for more
than a few hours to a few days but if you have old galvanized iron pipe and the rust or color
does not stop after a few days it may mean that your pipes are corroded or deteriorated.
Best Practices for Piping & Drain Installation
1.
See typical installation (see Fig 1). The nitrate filter is installed after the pressure tank.
2.
Make sure to connect the inlet pipe to the Fleck 9100 inlet and the outlet to the outlet (see Fig
2). You can see the in and out arrows on the bypass valve which is where the pipes are
connected.
3.
Make sure there is a working gate or ball valve before the nitrate filter and also one after as
shown in the diagram. If you are installing multiple filter systems (such as iron filter then
nitrate filter) you do not need a valve in between each system. The pressure gauges are
optional and not necessary but a hose bib (which is a faucet that you can attach a garden hose
to) is strongly recommended after the nitrate filter before the second ball valve. This makes it
easy to rinse your new nitrate filter on start-up and gives you a place to test the water before it
enters your household plumbing.
4.
If you will be using copper piping, do not sweat the copper pipe directly on to the Fleck 9100
bypass valve. Avoid heating up the bypass valve with the torch.
