Plumbing & Performing Tests
Identify Injector Manifold Location
The injector manifold must be installed in the pool’s main return line AFTER all other pool equipment (pump, filter, heater and cleaner).
Ozone gas is introduced to the pool circulation line using a venturi injector. Suction developed by the venturi allows the DEL Ozone generator to operate safely under vacuum.
Verify Water Level
The injector manifold should be installed above water level whenever possible.
If the injector manifold is installed below water level, take proper precautions by preventing water from draining through the injector and damaging the surrounding area.
You can use clamps on all tube connections, run ozone tubing above water level and provide adequate drainage around the pool equipment, as needed.
Plumb the injector manifold
Locate an appropriate section of the return line and install the injector manifold with PVC cement.
Be very careful to observe and follow the correct water flow direction (as indicated by the arrow on the injector manifold).
Install check valve
A check valve must also be installed between the pump outlet and the injector manifold to prevent the pump from draining and losing its prime (when not in use).
If the pool equipment is mounted above the water line, a check valve must be installed between the pump outlet and the Injector Manifold.
This will prevent the pump from draining and losing its prime (when not in use).
Perform a Pressure Test
If a pressure test is required, it should be performed prior to connecting the Ozone Gas Line.
Install the 3/4” pipe cap provided onto the Injector for the pressure test.
Perform a Flow Test
1. Install Tube Adapter on injector. Use Teflon thread tape as needed.
2. Connect the Flow Meter Assembly to the Tube Adapter.
3. Hold the Flow Meter Assembly so that the clear plastic chamber is vertical with the tubing on top.
4. Turn on the pool’s circulation system, allowing the Injector Assembly to pull a vacuum.
Under normal operation, the ball in the Flow Meter Assembly will be floating in between its Max and Min line.
Under worst-case system conditions the flowmeter ball should indicate at least a small amount of air flow.
Flow may be adjusted.
What type of valve is equipped on the injector manifold?
Rigid Injector Manifold
Operating the Adjustable Injector Manifold
Gas flow can be controlled by adjusting the Valve on the Manifold.
Close the valve to increase gas flow.
Open the Valve to decrease gas flow.
Operating the Rigid Injector Manifold
This manifold is equipped with a spring loaded valve.
It cannot be adjusted, but provides a wide operating range.
If more gas flow is necessary, verify that other valves in the system are not inhibiting flow through the Manifold.
