Summer Aerator Installation
Match your filter tubing size to the correct size aerator:
PA 50 (uses 1/2” tubing)
minimum flow rate 300 GPH - will infuse .88 cubic ft of air per hour.
PA 75 (uses 3/4” tubing)
minimum flow rate 500 – 720 GPH.- will infuse .96 cubic ft. of air per hour.
PA 125 (uses 1 1/4” tubing)
minimum flow rate 1200 GPH - will infuse 1 + cubic ft of air per hour.
Example 1: Install the aerator into your filter’s discharge tubing. From the discharge tubing of your pond filter, insert the aerator fitting (hose barb), making sure the flow arrow (as shown on the bottom side of the aerator fitting) is installed and pointed in the direction of the water flow.
Attach one end of the _” tubing provided to the top of the aerator nipple. The other end should be attached to the disc. We suggest that you use all 4 feet of the tubing so that the disc will float even when the water level fluctuates. You can also just lay it over the ponds edge on the outside.
Set the disc dial to full open for full aeration. Do not attach anything on the discharge side of the aerator because it will cause back-pressure in the filter. If back-pressure is in your system or if the aerator nipple is installed backwards [flow arrow-bottom] , the aerator will spout water out of the disc instead of infusing air.
Example 2: Aerator set into a waterfall. An aerator can be installed directly into a waterfall from the discharge tubing of a filter.
Attach the aerator fitting, hose barb, onto the end of the filter discharge tubing. Allow the other end of the aerator fitting to discharge water just below the surface and draw in air from the top small _”nipple opening. It will not be necessary to use the tubing or disc that was supplied.
Do not attach anything on the discharge side of the aerator because it will cause back-pressure in the filter. If back-pressure is in your system or if the aerator nipple is installed backwards [flow arrow-bottom] , the aerator will spout water out of the disc instead of infusing air.
