Section 4 Maintenance & Service
3E. Water Chemistry
Regular chlorine or bromine testing should be performed as normal.
Ozone will be eliminating the majority of contaminants. Therefore, only
a small amount of chemicals will need to be added - just enough to
maintain a minimum of residual level of 0.5 - 1.0 ppm chlorine or 1.0 -
2.0 ppm bromine. Ozone is pH neutral thus minimizing pH adjustments
4A. System Electromechanical Overview
4A-1. Ozone Module
The DEL Ozone Generators are constructed with high voltage plasma
gap Ozone Modules. The Ozone 25, Ozone 50, and Ozone 100 have
2, 4, and 6 modules, respectively. Each module has an indicator light
that signals it's working properly. If the light goes out, replace the
module.
4B. System Maintenance
4B-1. The green indicator lights on the Ozone Modules located
inside the enclosure indicates that the Power Supply is operating
properly. When an indicator light goes out, replace the corresponding
Ozone Module. Regularly check inside the unit to verify all the Ozone
Modules are working.
4B-2. Each Ozone Module should be replaced after 15,000 hours of
operation. Even if the green indicator light(s) are glowing, the Ozone
Module may be producing less ozone after this period of time due to
contamination within the plasma gap ozone chamber.
4B-3. Regularly reinstall and check the flowmeter for proper flow.
Always remove the flow meter after confirming proper flow. Inspect
Ozone Tube for cracks or wear and replace as necessary.
4B-4. Replace the Ozone Tube every year or sooner, if needed. If
there is evidence of water leaking past the Check Valve toward the
DEL Ozone generator, shut down the unit immediately and replace
the Ozone Tube and Check Valve. If water entered the DEL Ozone
generator, allow the unit to dry completely before restarting. Evidence
of water in the DEL Ozone generator may void the warranty.
