When locating the filter remember they can be buried in the ground up to the 6" neck. If you do decide to bury it make sure the bottom sludge drain plug is either closed, or piped above ground. When charging the filter with the media, use the neck insert to hold the vertical internal piping in position, then pour the media into the filter. Next remove the neck insert, and replace it with the Hayward 7 position valve. Position the valve so your pressure gauge, pump inlet orifice, pond outlet orifice, and waste orifices are all in a convenient location. When changing valve positions it is best to turn off the pump, change the valve position, and then restart the pump.
Screw the little "sight glass" bottle into position. Screw the pressure gauge into position. When plumbing the filter remember to use unions and valves in case you ever need to remove it, or tighten your plumbing fittings, etc. When installing the fittings remember to use about 10 wraps of Teflon tape, which seems to prevent leaks better than Teflon paste. When everything has been done, make sure there is water flow to your pump, put the valve in filter position and turn your pump on. If you have valves controlling various flow positions like fountains, water falls, etc, adjust them to get the effect you want. As soon as everything is adjusted to your liking, note the pressure reading on the gauge and record it so you can refer back to it later on. After a few days of filter operation your may notice the pressure gauge increase by a pound or two. This is a good indication that it is time to backwash. I backwash twice a week, only once if I am too busy. Simply turn off the motor, turn the valve to backwash, and turn the motor back on. Hopefully, you have already attached a 2" blue plastic hose to the waste line and have positioned it to a drain, sewer, street, etc. (If you maintain a salt level of 0.3% in your pond you may not want to water your garden with the pond waste.) After backwashing for about a minute you should notice the sight glass bottle clearing up. When it does you have finished backwashing. Turn the motor off, and turn the valve to rinse. In the rinse position the water goes through the filter media, but instead of returning to the pond, it is flushed out to waste. Turn the motor back on and watch the sight glass bottle. It should clear up in about 30 seconds. Turn the motor off, change the valve position back to filter, turn the motor back on, and you are done. If you need to medicate your pond, and you want to bypass the filter, turn the motor off and change the valve position to recirculate. Recirculate short circuits the water back to the pond without going through the filter media. Turn the motor back on and the medication will not reach the bacteria in your filter, and your pond will still be oxygenated by the waterfall, fountain, etc. After the medication period, turn the motor off, return the valve position to filter, and turn the motor back on. When vacuuming turn the valve to waste. Otherwise the fine sediment from the bottom of the pond will go through the filter and stay in your pond, but it will be re-suspended and make the water cloudy until it settles out again. Your motor should have a strainer in it. If it does, don't forget to clean out the motor strainer once a week or as needed. Good luck, if you have any questions contact us. |
