Programming the Effector Flowmeter Display

Each aerator air flow can be monitored very accurately on the individual effector flowmeters. They are normally set for “scfm” standard cubic feet per minute as shown by the left most LED green indicator being lit. If for some reason, the setting is changed, the following procedure will restore the program back to displaying scfm.

With power on, press “mode/enter” until EF is displayed. Press “set” and HI is displayed

Press “mode/enter” until UNI, press and hold “set “until display stops blinking

Press “set” when scfm is displayed, then press “mode/enter” to complete the program.

The display will read 0.0 when there is no air flow. The maximum air flow reading is 134 scfm. Do not exceed 100 scfm on any aeration device as this is the maximum air flow tolerated. Total airflow capacity of compressors is about 220-240 SCFM.

Weed Advice

As the lake lowers, members should aggressively manage the weeds in front of their property. The following are some suggestions of what can be done.

Pull weeds and remove both plant and root system. Remove weed fragments. Place them in a compost area away from the shoreline to dry and later be used as organic compost. A weed rake is specially useful. Do not leave removed weeds in the lake bed because they will germinate into weeds next year. Roots left in sediment will regrow next year.

After removal, and the shoreline is dry, till or scrape the sediment to expose the area to freezing temperatures to discourage germination and regrowth next spring.

If you have an existing blanket that’s been submerged, try to remove it and clean it before redeploying. As the water rises, wave action may displace the blanket. To prevent this from happening, weight the edges down with slabs of stone, tile, sand bags etc.

It is easier to install new weed blankets while the lake is down and the bottom exposed. It is also better for the creatures that live in the lake bottom (mussels, crayfish, snails, etc.). Most blankets are made of plastic and will float if not sufficiently weighted down. Sediment deposits on the blanket. This will require the blanket to be removed periodically every year or two. Blankets need to vent gas. Otherwise, they will become buoyant and rise to the surface. Woven blankets are good and will allow gases to escape. But plastic sheet blankets need to be punctured or slit every two-three feet. Be careful when placing blankets where propeller wash can disrupt them. Make sure they are well secured to the bottom. Restrict the area of permanent blankets to just the swim area. If we need to cut weeds with the harvester, we don’t want to snag your blanket.

It violates Normanoch Rules and State regulations so please don’t do it.
