Install By-Pass Plumbing
Before Proceeding
Use nonmetallic plumbing.
For pools equipped with a heater, the by-pass plumbing tee to the injector should be installed BEFORE the heater.
Any by-pass that connects back to the main pool return should occur AFTER all other equipment to avoid collection of gas in the system and possible failure of pool system components.

Observe and follow the correct flow directions on all components.
A variable rate check valve will ensure adequate by-pass flow through the Injector, which will create suction to pull in the ozone.
It will also effectively limit the total by-pass flow to less than 20 GPM for optimal germicidal UV effectiveness.
Confirm Pool Return Configuration
The recommended configuration is a dedicated pool return from the DEL AOP S.
If a dedicated pool return is not possible, a connection back to the main pool return may be used.
