2C. Electrical
2C-1. 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.
2C-2. Earth Grounding Lug
Using an 6 AWG (13.3 mm2) conductor, connect the Grounding lug
on the bottom of the DEL Ozone generator, marked to an appropriate
earth contact.
2D. Plumbing
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.
2D-1. 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.
Section 2 Installation

ENGLISH
4
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).
2D-2. Water 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).
Note: If a 1/3# DELCheckTM is used, do not install immediately after
chlorine feeders.

2D-3. 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.
2D-4. Flow Test - Refer to Figure 3a.
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 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.

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.
Rigid Injector Manifold: This Manifold is equipped with a
DELCheckTM 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. If
you experience complications see TROUBLE SHOOTING Section 4D.
2D-5. 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.

3A. General
To achieve optimal performance from the ozone system, the pool
must be as clean as possible to start with.
1. Backwash or clean filters one day before starting the ozone generator.
2. Superchlorinate pool water using a chlorine based shock treatment
prior to ozone system start-up.
3. Test pool chemistry and adjust pH between 7.4 and 7.6. Adjust
total alkalinity between 80 and 120 ppm.
4. Run pool filtration continuously for 24 hours prior to starting
ozone system.
3B. 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.
1. Check electrical connections.
2. Check for proper voltage.
3. Turn on pool circulation system.
3C. Normal Operation
1. 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. The Ozone 25, Ozone 50, and
Ozone 100 should show 2, 4, and 6 indicators, respectively.
3D. System Shut-Down
The following sequence of steps must be followed for servicing or for storage.
1. Disconnect the power to the ozone generator.
2. After the generator has been shut down, the pool water circulation
pump may be turned off.
3. If the system is to be shut down for an extended period,
disconnect the Ozone Tube from the unit.
Section 3 Operation

ENGLISH

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.

WARNING: Do NOT touch the ends of the Ozone Tube when
replacing. Trace amounts of nitric acid may be present and could
prove harmful if touched or ingested.
4B-5. While operating, check to see if bubbles are entering the pool.
If an MDV is installed, check the MDV for bubbles.
4C. Generator Servicing - Refer to Figure 4
4C-1. 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.
4C-2. Ozone Module Replacement
The Ozone 25, Ozone 50, and Ozone 100 have 2, 4, and 6 Ozone
Modules, respectively. When the green indicator lights go out, the
corresponding Ozone Module will need to be replaced.

2. Locate the Power Supply Connector and disconnect it from the
wire harness.
3. Remove the Power Supply Mounting Screw; make sure to note
plastic spacer and the star washer positions for proper reassembly.
The Ozone Module and Power Supply can now be removed from
the unit.
4. Install the new Ozone Module by reversing the above steps.
4D. 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 DEL technical support (see
section 4E)
4D-1 Symptom: Module Indicator Lights not lit when pool system is
on.
1. 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.
2. G.F.C.I. has tripped.
a. Check power cord and reset G.F.C.I.
4D-2 Symptom: Flowmeter not indicating flow.
1. 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.
2. Tubing is impaired.
a. Check for kinks or clogs.
b. Check for cracks or cuts.
Section 4 Maintenance & Service

ENGLISH
11
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.
4D-3 Symptom: Ozone Tube becomes yellow/brown and brittle.
1. 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.
4D-4 Symptom: Can’t get ball to stay in the center of flowmeter.
1. 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.

DEL Ozone Installation –Plumbing
4-1393-01_Rev.B
The DEL Ozone series generators work under vacuum. The Injector Manifold drawsthe ozone/air gas mixture out of the
ozone generator and mixes it into the water leaving behind some un-dissolved gas bubbles.These bubbles can affect
certain pool system components, so care must be taken when installing the ozone Injector Manifold.
The diagrams below cover common plumbing configurations. For other configurations or installation questions, please
call DEL Residential Pool & Spa Technical Support at 1 [phone], or e-mail: [e-mail]
Pool Cleaners (i.e. Polaris 360): Always plumb the cleaner t-fitting before the DEL Ozone injector to prevent gas
from affecting the operation of the cleaner.
Salt Chlorinator: A Salt Chlorinator may be plumbed on either side of the DEL Ozone injector.
Chlorine Tab / Mineral Erosion Feeder: Always plumb the DEL Ozone injector after any erosion feeder to avoid
gas accumulating in the feeder.
In-Floor Cleaning System: The DEL Ozone Injector must be on a different pool return leg than any In-Floor
Cleaning system to avoid excess back pressure on the Injector.This will also prevent gas intrusion and high oxidizer
levels in zone valve and cleaner heads.
Water Features: Avoid plumbing the Injector Manifold into any leg with excessive back pressure such as those
going to fountains, restrictive wall fittings, etc.
