Product Overview

NOTE: Fixed Shipping Rate is not valid for Hawaii or Alaska.

The JED 603 is designed for water purification in residential and commercial hot tubs, small pools, fountains, cisterns and water tanks up to 5,000 gallons. The JED 603 is supplied in a plastic rainproof enclosure that can be wall mounted outdoors. The JED 603 has its own air compressor that can pump ozone into a pool, tub, or tank up to 24 hours a day independently of water circulation.  

Unlike other sellers, our JED 203 includes an "over the side kit" for super easy diffusing of ozone into the water. The over the side kit includes 20' of ozone tubing that connects to the Ozone Generator and should be installed over the top of the water tank sidewall. An included bubbler stone on the end of the tubing ensures effective diffusion of the ozone into the water. 

The bubbler stone should not be installed any deeper than 4' in a water tank. Installation of the diffuser deep than 4' will cause premature failure of air compressor.

Troubleshooting Tips

It is unusual for one of these units to fail during the warranty period. Typically if a JED Model 203 or 603 fails within the first year of use, something has blocked the airflow. Having the air stone positioned deeper than 4 feet below the surface of the water can also cause an issue. If the water inside the tank is deeper than 4 feet, you may devise a float in order to keep the air stone suspended at no more that 4 feet beneath the surface of the water. This allows the air stone to move up and down with changes to the water level without allowing it to fall deeper than 4 feet. Other possibilities that can block airflow would include a clogged air stone, kinked air hose, or the tubing getting pulled/yanked out of the corona discharge assembly—even only slightly. This causes ozone to fill the enclosure and destroy the unit. In some cases, a lightning strike can take out the transformer, and while the air pump might still work, it may no longer produce ozone.
