Prime & Start the Pump
1.
Fill solution tank with 5 gallons of softened, distilled or RO water but don’t add Alum yet.
2.
Connect the suction tubing to the foot valve and discharge tubing to your injection check valve.
3.
Connect the degassing prime valve tubing and route to the solution tank, above the water line.
4.
Open the degassing prime valve approximately one turn counterclockwise to open. This will
allow the solution to be pumped back into the tank for fast priming.
5.
Turn on the pump and set Speed to 100% to help prime the pump if not already displaying 100
6.
You will quickly see water being pumped up the suction tubing and out of the degassing valve
return line port.
7.
Close the degassing port valve to allow liquid to pump out the discharge side. Open and close
degassing valve as required to prime pump. Close degassing valve once pump is primed for
normal operation.
8.
To start mix 2 lbs of alum powder (2-1/2 Cups) in to the 5 gallons of water and mix thoroughly.
Some alum may not mix and settle which is normal.
9.
Turn on system or run water and allow to run for 10-15 minutes. Check for leaks. After your
Alum metering pump has been running for a few days, tighten 4 stainless steel bolts on the
pump end.
Metering Pump Buttons
Out of the box, when you plug the unit in, the green Motor light is
indicating the pump has power. It will be set at 100 and start pumping.
Press the Start/Stop button to stop the unit from pumping. The Up and
Down arrows are to adjust the Speed of the pump, from 0-100.
The Set button and the Auto light indicator have no function on this
