Location

The DEL Ozone units are designed for wall mounting. Mount generator in a clean, protected area, either indoors or outdoors (preferably out of direct sunlight). Locate generator out of reach of sprinklers or drainage spouts. Allow sufficient access for maintenance, all tubing, and electrical wires. Ozone generator should be installed at least (not less than) one foot above the maximum water level.

Wall Mounting

Open the enclosure door and locate the three mounting holes on the back wall of the enclosure. There will be two holes located near the top on the left and right and one located in the center near the bottom. Refer to Figure 1 for clarification.
Install screws (or other hardware appropriate for the mounting surface) through the two mounting holes near the top of the enclosure. Install the last screw through the mounting hole near the bottom of the enclosure. Mounting hardware must be driven until the head fully contacts the enclosure wall. Mounting hardware head must not be smaller than 0.25 inches (6.3 mm) in diameter and the threads of the hardware must be smaller than 0.25 inches (6.3 mm) in diameter.

Plumbing

CMP DEL OZONE 25 Generator Instruction fig2

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.
Note: Water must not travel back to the ozone generator. Mounting the unit above the water line and scheduled check valve replacement will keep water from entering the DEL Ozone generator.

Plumbing the Injector Manifold

The injector manifold must be installed in the pool’s main return line after all other pool equipment (pump, filter, heater, and cleaner). Figure 2 shows the most basic installation. For installation with additional oxidizers and pool cleaners, refer to Appendix A.
Note: The injector manifold should be installed above water level whenever possible. If the injector manifold is installed below water level, take proper precautions to prevent water from draining through the injector and damaging the surrounding area. For example, use clamps on all tube connections, run ozone tubing above water level and provide adequate drainage around the pool equipment.
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).

Water Line Check Valve

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). CMP HydroSeal™ check valve recommended.

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 pressure test.

CMP DEL OZONE 25 Generator Instruction fig3

Flow Test – Refer to Figure 3a.

Install tube adapter on injector. Use Teflon thread tape as needed.
Connect the flow meter assembly to the tube adapter.
Hold the flow meter assembly so that the clear plastic chamber is vertical with the tubing on top.
Turn on the pool’s circulation system as this allows 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 as described below.

Manually 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.

Self-Adjusting Injector Manifold: This manifold is equipped with a spring loaded valve. It cannot be manually 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. If you experience complications see TROUBLESHOOTING.

Ozone Tube Connection – Refer to Figure 3b.

After the system has been set for the correct flow rate, remove the flow meter assembly and connect the ozone tube between the ozone outlet barb on the DEL Ozone generator, and the tube adapter on the injector assembly. Ensure that the check valve arrow is pointing toward the injector. If equipment is above water level, cut off the excess tubing so that the line from the injector to the DEL Ozone generator is as straight and free from dips and loops as possible. If equipment is below the water level, run tubing to a point above water level. Ensure that all tube connections are secured with clamps.

Electrical

Main Power

This device is intended to be installed by a certified electrical technician, in accordance with local electrical codes. Connect the DEL Ozone generator to the pool timing clock so that the DEL Ozone generator operates simultaneously with the pool pump. The DEL Ozone generator has three available knockouts for a 1/2 inch conduit fitting, two on each side and one on the back. Remove only the ideal knockout and install the proper conduit fitting. Open the enclosure and locate the terminal block. Connect Line 1, Line 2, and ground to the terminal block as indicated by the label on the inside of the enclosure door. Refer to the IMPORTANT SAFETY INSTRUCTIONS at the beginning of this manual for important wiring information.

Earth Grounding Lug

Using an 6 AWG (13.3 mm2) conductor, connect the grounding lug on the bottom of the DEL Ozone generator to an appropriate earth contact.

OPERATION

General

To achieve optimal performance from the ozone system, the pool must be as clean as possible to start with.

Backwash or clean filters one day before starting the ozone generator.
Superchlorinate pool water using a chlorine based shock treatment prior to ozone system start-up.
Test pool chemistry and adjust pH between 7.4 and 7.6. Adjust total alkalinity between 80 and 120 ppm.
Run pool filtration continuously for 24 hours prior to starting ozone system.

Initial System Start-Up

Upon completing all of the generator system connections and cleaning the pool as outlined above, you are ready to start the ozone generator.

Check electrical connections.
Check for proper voltage.
Turn on pool circulation system.

Normal Operation

Indicator Lights: When the pool’s circulation system starts, the DEL Ozone generator will power up and the green indicator lights on the ozone cells will illuminate. Open the enclosure door to verify that all indicator lights are green.

System Shut-Down

The following sequence of steps must be followed for servicing or for storage.

Disconnect the power to the ozone generator.
After the generator has been shut down, the pool water circulation pump may be turned off.
If the system is to be shut down for an extended period, disconnect the ozone tube from the unit.

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 an appropriate residual level of chlorine or bromine. Ozone is pH neutral thus minimizing pH adjustments.

MAINTENANCE & SERVICE

System Electromechanical Overview- Ozone Module

The DEL Ozone generators are constructed with high voltage plasma gap ozone modules. Each module has an indicator light that signals it’s working properly. If the light goes out, replace the module.

System Maintenance

The green indicator lights on the ozone modules located inside the enclosure indicate that the power supplies are 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.
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.
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.
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.
WARNING Trace amounts of nitric acid may be present in the ozone gas line. Wear proper safety equipment (gloves and eye protection) and avoid direct contact with any condensation in the line.
While operating, check to see if bubbles are entering the pool. If an MDV is installed, check the MDV for bubbles.

Generator Servicing

Opening the Unit
The DEL Ozone generator may be serviced on the wall without disconnecting any of the plumbing or wiring. Simply remove the two screws on the right side of the enclosure door to open the unit.

Ozone Module Replacement

When the green indicator lights go out on the ozone modules, the corresponding ozone module will need to be replaced.

To replace an Ozone Module:

Disconnect the manifold or tubing from the ozone module.
Note: For the Ozone 25 and Ozone 50, pull the tubing clamp back from the ozone module barb connector, then pull the tubing from the barb.
Locate the ozone module power connector and disconnect it from the wire harness.
Remove the ozone module mounting screws. The ozone module can now be removed from the unit.
Install the new ozone module by reversing the steps.

TROUBLESHOOTING

Knowledge of electrical applications is required for trouble shooting. Contact a certified electrician if you are unsure of your ability to service the equipment. Improper servicing will void generator warranty. If any condition persists contact CMP technical support (see section 4D)
Symptom: Module Indicator Lights not lit when pool system is on.

No power to the ozone generator from the power source:
a. Check circuit breaker at the power distribution box.
b. Check for loose connections or wiring breaks from the power distribution box to the generator.
c. The fuse in the unit has blown and needs to be replaced. The fuse is a replaceable glass, .25” x 1.25”, 1 amp, slo-blo type.
G.F.C.I. has tripped.
a. Check power cord and reset G.F.C.I.

Symptom: Flowmeter not indicating flow.

Injector not supplying adequate suction.
a. Check pump, filters, and skimmers to ensure water is flowing through injector.
b. Ensure that there is no debris clogged inside the injector.
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 tube from the injector. With the pump running, cover the end of the injector with your thumb, and feel for suction. If there is sufficient suction without the check valve, replace the check valve with a new one.

Symptom: Ozone tube becomes yellow/brown and brittle.
The high concentration of ozone created by the DEL Ozone family of ozone generators, as well as environmental conditions like UV sunlight will tend to deteriorate the supplied ozone tube. This is normal and acceptable, as long as the tubing doesn’t become cracked and leak. Because of this, the ozone tube and check valve should be replaced every year.

Symptom: Can’t get ball to stay in the center of flowmeter.
The flowmeter provided is a general tool to setup flow to the ozone generator. Flow will vary depending on pressures across the injector, and therefore can be affected by things such as filter or strainer loading. The ozone generator’s efficiency is optimized near the center of the flow meter. The DEL Ozone generator will still perform well at flows above and below the recommended range. However, the ball must be moving and not stuck on the bottom of the flowmeter.
