Installation Guide

The Outdoor Water Solutions AerMaster Pro Electric Aerator is designed to help keep your pond
clean and healthy year around. We hope you enjoy your Aeration system for many years to
come.
Installation Instructions:
Attach your airline to each of the airlines exiting the AerMaster cabinet. Run each airline out to
the place in the pond where you want your diffuser and attach your diffuser. For diffusers with a
base, lower the diffuser down to the bottom of the pond. Using a thin rope can help to keep the
diffuser and base upright. You don’t have to tie the rope on, just fold the rope in half, lower the
diffuser, then pull the rope up by pulling on one half. Note: For rubber membrane diffusers
with a base, you will need to unscrew the rubber membrane from the base and add some
sand or gravel to add weight so it will sink to the bottom.
If your diffuser does not have a base (rubber membrane diffuser or ceramic air stone), then
inserting the diffuser into a bucket can help keep it out of the mud and muck on the bottom.
Adding 3-5 lbs. of sand or rock to the bottom of the bucket prior to inserting your diffuser helps
sink and stabilize your bucket. Note: Teflon tape is recommended, but not required for
threaded connections. If you have a rubber membrane diffuser with the airline coming off
of the side, you can drill a hole in the side of the bucket and run your airline thru the side.
We also suggest installing your diffuser into the deep part of the pond to ensure complete
circulation of your water. The exception to this would be if you’re wanting to keep the water
open for watering livestock in the winter, then you can put the diffuser closer to the shoreline (or
move it there in the fall). You can also place the diffuser in a more shallow area if you are in a
northern climate and have trout, walleye, Northern pike or Muskie in the pond and want the deep
parts of the pond to remain colder in the summer months.
The use of OWS Weighted Air Line will help keep the airline submerged and on the bottom of
the pond. In the absence of using weighted airline, tie rebar, bricks, blocks, etc. to non-weighted
airline to help keep it submerged.
Note: Air will travel to the point of least resistance or to the shallow diffusers first. Adjusting
the airflow so that it goes to the deepest diffusers is usually required.
Note: We recommend turning your electric aerator on for an hour the first day, then increasing
the time by a couple of hours each day until it is running continuously. On rare occasions, you
can have a pond “turnover” if you turn aeration on continuously in a pond not previously aerated.
This means the oxygen deprived water in the bottom of the pond rises to the top and your fish
cannot survive due to the low oxygen conditions. Doing this over the course of 3-4 days can
prevent any potential issues.
