Step by Step Instructions

1. Bring the water level up to the top of your skimmer. When you backwash, you will lose a lot of water. Have your D. E. by the pool.
2. If you have a Polaris, or any pressure side cleaner, make sure the cleaner motor is off. Then, turn the pool pump off, then disconnect the cleaner from the wall fitting during the backwash procedure.
3. Turn the multi-port valve handle to the backwash position.
4. Turn the pool pump on. Watch the sight glass for trash and clarity. When the sight glass is clear, turn the pool pump off again.
5. Turn the valve to the rinse position and turn the pump back on for approximately 10–20 seconds. Turn the pool pump off again.
6. Repeat steps 4 and 5 until the sight glass is completely clear in the backwash cycle from start to finish.
7. Return the valve to the filter position. Start the pool pump. You have one (1) minute to get the D. E. into the skimmer before you mess up any grids in the filter. Get the reading off the pressure gauge, this is the starting pressure. Backwash the filter when the pressure is 8–10 pounds over starting pressure.

Chemically clean and inspect the filter at least once per year

Note:

• FNS 24 is 3 scoops after backwash, 5 scoops after tear down.
• FNS 36 is 5 scoops after backwash, 7 scoops after tear down.
• FNS 48 is 7 scoops after backwash, 9 scoops after tear down.
• FNS 60 is 9 scoops after backwash, 11 scoops after tear down.
