Plumbing
Ozone gas is introduced to the circulation line using
a venturi in-line injector. Suction developed by the
venturi injector allows the generator to operate
safely under vacuum. See installation manual
for Model 521683 or 521684 for proper venturi
installation.
Ozone Gas Line
1. Connect ozone tubing to generator outlet fitting.
(3/8" stainless steel compression fitting.)
2. Connect opposite end of ozone tubing to injector
suction port. (Suction port fitting: 3/8" stainless
steel compression fitting.) See Figure 4.
NOTE: The ozone gas supply line must be
made of PTFE or stainless steel and have a
back flow prevention device (such as a check
valve) installed between the ozone generator
cabinet and the point of injection to prevent
water from backing up into the generator
system. An ozone supply check valve is
included with the Model 521683 or 521684
system.

Colling water Pressure: 15–40 psi (103–275 kPa)
Cooling Water Temp.: 5–90˚F (10–32˚C)
1/4" FPT connections are supplied on the
generator. See Figure 4, 5a, 6a. Be sure that
the tubing is appropriately matched with the marked
inlet and outlet ports. Carefully match and connect
to water plumbing as shown in Figure 4. Alternate
method using connections at injector may be used.
SECTION 3 Operation
Initial System Start-Up
Upon completing all of the generator system
connections, you are ready to begin start-up
procedures.
1. Check electrical fittings.
2. Check for proper voltage.
3. Turn on circulation pump.
4. Check for leaks.
5. With the ozone isolation valve closed, adjust the
injector bypass valve and/or filtration sidestream
valve to flow water through the injector.
6. Check cooling water.
7. Open the ozone isolation valve.
8. Turn main power switch to "ON" position.
9. Adjust injector by-pass to attain required vacuum.
(Red "Vacuum" light will go out.) Gas flow
(as indicated by the flow meter on the door of
the unit) should correspond with the rating listed
for the specific model on the specification label.
Normal Operation
With the power switch on, the system’s
compressors and cooling fans will start-up, the
oxygen concentrator will begin operating, and
the output solenoid valve will open. With the
injector adjusted to attain the correct gas flow,
the ozone generator should be producing ozone
and injecting it into the process line.
Both (2) green indicator lights should be lit. If
an optional ORP Controller is installed, it should
be displaying a reading from the sensor probe
and will automatically cycle the generator on and
off as needed to maintain water quality. Residual
ORP levels will vary per application.
However, the system will not start under any of
the following conditions:
1. The system will not start-up if the door is not
secured. A door interlock switch is incorporated
into the system enclosure.
2. If the optional ORP/DO3 controller is installed the
system will not produce ozone if the measured
level is already above the setpoint of the controller.
3. The system will not produce ozone if there is not
enough vacuum being generated by water flow
through injector. The red "Vacuum" light will go
out when proper vacuum is attained.
If you experience complications, see APPENDIX
A, TROUBLESHOOTING GUIDE or call
800.831.7133 for assistance.
System Shut-Down
The ozone generator is a specialized water
cooled device that must be properly protected
during shut-down/storage periods. The
following sequence of steps must be used for
servicing or for storage.
1. Toggle the main system power switch to the
“OFF” position to shut-down generator.
2. Close the ozone isolation valve to prevent water
back flow.
3. After the generator has been shut-down, the
process water circulation pump may be turned
off.
4. If the system is going to be shut-down and
stored during freezing weather, it is very
important that the cooling water be drained to
protect it from rupture or damage.
NOTE: Process water flow must not be shut-
down when the ozone generator is operating.
Doing so may cause water to backflow into
the system and damage the generator cells.
SECTION 4 Maintenance & Service
System Electro-Mechanical Overview
Refer to Figure 5a and 6a for component locations.
Indicator Lights
1. Main Power: Green light indicates that power is
being supplied to the ozone generator.
2. Ozone Power: Green light indicates that power
is being supplied to the high voltage Corona
Discharge circuits and that ozone is being
produced.
3. Vacuum: Red light indicates a low vacuum fault
condition. (Refer to APPENDIX A
TROUBLESHOOTING).
4. High Coolant Temperature: Red light indicates
INTELLIZONE™ COMMERCIAL OZONE GENERATOR Installation and User's Guide
4
cell temperature is over 110F - resulting from
loss of cooling water flow. (Refer to APPENDIX
"B", TROUBLESHOOTING GUIDE.)
5. Water Backflow Detected: Red light indicates
water backflow from injector into generator.
(Refer to APPENDIX "B", TROUBLESHOOTING
GUIDE.)
External Components
1. Main Power Switch: Power switch is used for
system start-up and shut-down. Switch activates
the control system allowing the generator to
start up.
2. Flowmeter: Flowmeter controls and indicates
the oxygen flow through the system.
3. Circuit Breaker: Circuit breaker protects the
generator from over current conditions. Push
the breaker button to reset.
Internal Components
1. Variable Output Switch (optional): Adjusts
high voltage power supplied to the ozone
generator module controlling ozone output
concentration. Located on the outside of the
enclosure door.
External Devices that Control Ozone Production
The devices turn ozone production on or off
based on programmed level set points. Refer
to Figure 5b and 6b for connection details.
1. ORP Controller (optional): The ORP controller
receives a millivolt (mV) signal from the ORP
sensor mounted in the process water line. ORP
(Oxidation-Reduction Potential) is a measure
of the relative oxidation strength of the water.
As ozone is added to the water system the ORP
level will rise. As ozone is used up in the water
system the ORP level will drop. The ORP
controller continuously analyzes the sensor
signal, compares it to the setpoint that has
been programmed, indicates the ORP level on
the digital display, and relays the signal to the
ozone generator.
2. Dissolved Ozone Monitor (optional):
Monitoring system designed for the continuous
measurement of ozone gas in solution. The
operating range of the system may be selected
by the user from 0-2.00 PPM or from 0-20.00
PPM. The basic sensing element used is
polarographic membraned sensor which
measures ozone directly.
External Devices that Control System
Power
The devices turn power to the ozone generator
on or off. Examples of such devices would be an
ambient ozone monitor or flow switch. Refer to
Figure 5b and 6b for connection details.
Internal Components
1. Ozone Cell Assembly: Cells are made of two
aluminum halves. Enclosed in the aluminum
halves are a ceramic tube, coil type high voltage
electrode and a PTFE rod.
2. High Voltage Supply(s): Power supplies raise
incoming line voltage and frequency to deliver it
to the cells. Each power supply is rated at 100W.
3. Air Compressors: Compressors produce and
supply compressed air to oxygen concentrator.
4. Oxygen Concentrator: Supplies concentrated,
dry, oxygen feed gas to the ozone generator.
5. Low Limit Vacuum Switch: If the vacuum in the
ozone output supply line falls below 1.5 in. Hg
the switch will open causing the system to shut
down.
6. Vacuum Regulator: Regulates the oxygen
flow into the generator cell based on a vacuum
setpoint (factory set to 3-5 in. Hg). When the
sufficient suction is being developed by the
injectors downstream the regulator will allow full
flow to pass. As suction is reduced, flow is
restricted proportionally to maintain the vacuum
set point. If suction is lost completely, flow is
cut off.
7. Water Backflow: The backflow detector senses
water present in ozone tubing in generator. If
water is detected, system will close solenoid
valve to prevent additional water backflow from
occuring. Water in the generator will cause
severe damage to the high voltage electrodes.
8. Ventilation Fan: Cooling fan operates when
main power switch is “ON”.
9. Air Filter: Filter cleans ventilation air entering
the enclosure.
10. Door Interlock Switch: Interlock switch will
shut down entire system if door is opened.
Securing the door will bring the system back
into operation.
11. Relay Panel: Contains control relays for system
interlocks, indicator lights and main power
control.
12. Hour Meter: Indicates total system operating
time in hours.

Preventative Maintenance Schedule
Regular maintenance should be performed to avoid
damage to the system, more costly repairs and
to keep the warranty active. For instance, the
compressor should be rebuilt every 8,750 hours
to prevent the reduction in air-pressure and flow.
If the compressor is not rebuilt, oxygen concentrator
sieve beds will become plugged and unusable,
creating more costly problems. If the generator
cells are not cleaned or replaced annually, a lower
ozone output will result.
DAILY:
Check ozone generator for proper operation.
- Make sure no red indicator lights are lit.
- Make sure flow meter is indicating proper
air flow.
MONTHLY:
1. Inspect compressor air filter.
- Replace quarterly
2. Remove and clean air filter or intake screens
See Figure 7.
- Remove filter cover plate to access filter.
- Rinse filter in warm, soapy water and blow dry.
- Replace filter.
- For models 521761 and 521762, remove and
clean intake screens.
3. Perform general cleaning of cabinet interior.

FORMULA: O3 REVISED: April 3, 2012
Description (origin/uses): Occurs in atmosphere from UV light action on oxygen at high altitude. Commercially obtained by
passing air between electrodes carrying a high voltage alternating current. Also found as a by-product in welding areas, high
voltage equipment, or UV radiation.
Ozone is used as an oxidizing agent in air and water disinfection: for bleaching textiles, oils, and waxes; organic synthesis as in
processing certain perfumes, vanillin, camphor; for mold and bacteria control in cold storage
Cautions: A powerful oxidizing agent, ozone generally exists as a gas and is highly chemically reactive. Inhalation produces
various degrees of respiratory effects from irritation to pulmonary edema (fluid in lungs) as well as affecting the eyes, blood, and
central nervous system.

SECTION V: REACTIVITY DATA
Stability: Ozone is not stable. Hazardous polymerization cannot occur.
Chemical Incompatibilities: Ozone is chemically incompatible with all oxidizable materials, both organic and inorganic.
Conditions to Avoid: Ozone is unstable at room temperatures and spontaneously decomposes to oxygen gas. Avoid ignition
sources such as heat, sparks, and open flame. Keep away from strong reducing agents and combustible materials such as
grease, oils, and fats.
Products of Hazardous Decomposition: Ozone spontaneously decomposes to oxygen gas, even at room temperatures.

SECTION VI: HEALTH HAZARD DATA
Carcinogenicity: Ozone is not listed as a carcinogen by the NTP, IARC, or OSHA.
Primary Entry: Inhalation
Target Organs: Respiratory system, eyes, blood.
Summary of Risks: There is no true threshold limit and so no exposure (regardless of how small) is theoretically without effect
from ozone’s strong oxidative ability. Ozone passes straight to the smallest bronchioles and alveoli and is not absorbed by
mucous membranes along the way. Initial small exposure may reduce cell sensitivity and/or increase mucous thickness
producing a resistance to low ozone levels. Short exposure to 1-2 ppm concentrations causes headache as well as irritation to
the respiratory tract. but symptoms subside when exposure ends. High concentrations of ozone produce severe irritation of the
eyes and respiratory tract. Exposure above the ACGIH/OSHA limits produce nausea, chest pain, coughing, fatigue, reduced
visual acuity, and pulmonary edema. Symptoms of edema from excessive exposure can be delayed one or more hours.
Inhalation of >20 ppm for an hour or more (>50 ppm for 1/2 hour) can be fatal.
Acute Effects: Acute damage from ozone appears to be mainly from its oxidizing effect on contact with tissue.
Chronic Effects: Respiratory disease. Deleterious effects on lungs and acceleration of tumors have been reported.
Medical Conditions Generally Aggravated by Long-Term Exposure: History of respiratory or heart disorders.
First Aid: Remove from ozone containing air, get prompt medical help*, administer oxygen if necessary.
Eye Contact - Gently lift eyelids and flush eyes continuously with flooding amounts of water for 15 minutes or until transported to a
medical facility*.
Inhalation - Remove exposed person to fresh air, support breathing, administer humidified oxygen as needed, get medical help*.
Ingestion - Highly unlikely since ozone is a gas until -169 F,
* GET MEDICAL ASSISTANCE = APPROPRIATE IN-PLANT, PARAMEDIC, or COMMUNITY. Get prompt medical assistance for
further treatment, observation, and support after first aid.
SECTION VII: PRECAUTIONS FOR SAFE HANDLING AND USE
Steps to be Taken in Case of Spill/Leak:
1. Discontinue production
2. Isolate and vent area
3. Immediately notify personnel
4. Deny entry
5. Follow applicable OSHA regulations
Disposal: Provide ventilation to dilute and disperse small amounts of ozone (below OSHA PELs) to outside atmosphere. Follow
federal, state, and local regulations.
Handling/Storage Precautions: Ensure proper personnel training and establish emergency procedures.
SECTION VIII: CONTROL MEASURES
Respiratory Protection: High Level (>10 ppm) - Self Contained Breathing Apparatus: MISH/NIOSH approved.
Low Level (0.3 - 10 ppm) - Canister Type (carbon) respirator may be used.
Eye Protection: Wear chemical safety goggles if necessary to work in high ozone (>10 ppm).
Skin Protection: Effects of ozone on skin are minimal to non-existent.
Ventilation: Provide general and local exhaust ventilation to dilute & disperse small amounts of ozone into outside atmosphere.
SECTION IX: SPECIAL PRECAUTIONS AND COMMENTS
Storage Segregation: Prevent ozone from coming into direct physical contact with strong acids or bases or with strong
oxidizing/reducing agents.
Engineering Controls: Install ventilation systems capable of maintaining ozone to concentrations below the ACGIH/OSHA
exposure limits (see sect. II). Install ambient ozone monitor(s) configured to shut down ozone equipment and turn high speed
ventilation on.

Certified testing of DEL Ozone systems by NSF (National Sanitation Foundation) has shown that
under normal conditions of use, aqueous solutions containing low levels of ozone gas dissolved in
potable water do not present a safety hazard when contact to the individual is incidental. When
used in a room with normal ventilation, levels of ozone gas being released into the air have been
shown by NSF to be well below the periodic exposure levels established by OSHA for worker
safety through the use of DEL’s ozone management technology.
IX SPECIAL PRECAUTIONS
Precautions To Be
Taken In Handling
This material safety data sheet is provided as an information resource only. It should not be taken as a warranty or representation for which the preparer
assumes legal responsibility. While we believe the information contained herein is accurate and compiled from sources believed to be reliable, it is the
responsibility of the user to investigate and verify its validity. The buyer assumes all responsibility of using and handling the product in accordance with
applicable federal, state, and local regulations.
Aqueous solutions of ozone in potable water should not be sprayed as an aerosol (i.e. >20psi) to
avoid releasing higher levels of ozone gas into the work area. The decay rate of ozone gas is a
function of temperature and exposure to organic material. Certified testing has shown that when
ozone gas has been properly dissolved in ambient temperature (or colder (33 – 70 °F)) potable
water at a level not exceeding 2 mg/l (ppm) using DEL’s ozone management technology, the rate
at which ozone is released from the water as ozone gas is below the PEL established for gaseous
ozone.
