EC–AG 

Installation & Operations Manual

Symptom: No Flow.
1. Injector not supplying adequate suction. 

a. Check pump and ensure water is flowing through Injector. 
b. Check that pump skimmer and filter are clean. 
c. Check that Injector is plumbed in the right direction. 
d. Ensure that there is no debris clogged inside the Injector. 

2. Ozone Supply Tubing is impaired. 

a. Check for kinks or clogs. 
b. Check for cracks or cuts. 
c. Check connections. 
d. Check that the Check Valve is installed with the arrow pointing  

towards the Injector. 

e. Be sure that the Check Valve has not become fouled with 

debris. Disconnect the Ozone Supply Tubing from the Injector. 
With the pump running, test the end of the Hose Barb Fitting 
with your thumb, and feel for suction. Wash your hands 
immediately afterwards to remove any residual nitric acid. If 
there is sufficient suction without the Check Valve, replace the 
Check Valve and Ozone Supply Tubing.

 
Symptom: Ozone Supply Tubing becomes yellow/brown and brittle.
1. The high concentration of ozone created by the advanced 

plasma gap ozone generators, as well as environmental 
conditions like UV sunlight will tend to deteriorate the supplied 
ozone tubing. This is normal and acceptable, as long as the 
tubing doesn’t become cracked and leak. Because of this, DEL 
recommends replacing the Ozone Supply Tubing and your Check 
Valve every year.
