2C-1. External Control
Make sure that the control switch is properly
rated for the ozone generator. A pair of control
contacts is provided inside the ozone generator.
Refer to wiring diagram and Figure 4 for proper
connection.
2D. Plumbing
Ozone gas is introduced to the circulation line
using a venturi injector. Suction developed by the
venturi allows the CD generator to operate safely
under vacuum.
2D-1. Injector Assembly
Plumb the Injector and/or Degas Assembly into the
water line according to the installation instructions
for that assembly. The Injector/Degas Assembly
must be installed in the main return line after all
other pool equipment.
2D-2. Water Check Valve (optional item)
If the pool equipment is mounted above the water
line, a 1/3# DELCheck check valve (P/N: CO-0101)
must be installed between the pump outlet and
the injector assembly.
2D-3. Ozone Gas Line
1. Install the ozone check valve (contained in parts
bag) into the ozone output fitting on the
generator. Apply Teflon tape, Mil T-27730A or
equivalent, to threads. Flow direction is away
from the generator. Install elbow or straight
MPT-to-compression fitting (contained in parts
bag) onto check valve. Insert one end of ozone
tubing into the fitting, hold the tubing in place
and tighten the fitting.
NOTE: Use a back-up wrench when
tightening all fittings.
2. The injector assembly is also equipped with a
compression fitting. Connect the other end of
ozone tubing to the injector suction port as
described in Step 1. See Figure 2a.
NOTE: The ozone gas supply line must have a

SECTION 3 Operation
3A. 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
injector bypass valve and/or filtration sidestream
valve to flow water through the injector.
6. Open ozone isolation valve.
7. Turn ozone generator on.
NOTE: If your Injector Assembly is equipped
with a ball valve, close the valve by turning
the handle clockwise until the proper suction
is indicated as described in Section 3B.
3B. Normal Operation
At this point, the system's cooling fans will
start-up and the oxygen concentrator will begin
operating. The green power indicator should
be illuminated and the red vacuum indicator
should turn off when sufficient vacuum is
obtained. The green ozone indicator should
then illuminate.
If the indicator lights are OK and the flowmeter is
reading the proper flow (refer to specification label
in unit), then the ozone generator is producing
ozone and the injector assembly is injecting the
ozone into the pool return/inlet line.
Make further adjustments to the injector bypass
valve until vacuum light turns off and the ozone
light turns on. NOTE: Do not exceed the max air/
oxygen flow rate specification as indicated on
the specification sticker.

Material Safety Data Sheet
SECTION I: MATERIAL IDENTIFICATION
IDENTITY:OZONE (Gaseous)
ISSUED: February, 1992
FORMULA: O3
REVISED: May 12, 2014
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.
Manufacturer/Supplier:On-site generation, equipment available from various suppliers, including:

Special Fire Fighting Procedures:Wear a self contained breathing apparatus with full face pieces operated in a pressure-
demand or other positive-pressure mode.
Unusual Fire/Explosion Hazards:Decomposition of ozone into oxygen gas, (O2), can increase strength of fire.
SECTION V: REACTIVITY DATA
Stability:Ozone is not stable. Hazardous polymerization cannot occur.

Genesis CD–2G, CD–5G, & CD–7G Installation & Operations Manual
4-0697_ Rev.D
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.
Precautions To Be
Taken In Handling
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.

1. Connect the 2-wire 4-20mA signal to the 4-20mA input + and – terminals at Terminal Block A.
2. Use the shortest wire route possible.
3. Use shielded wire.
4. Ground at the transmitter source only. DO NOT ground the shield at the terminal block input.
5. Avoid noise problems by routing cable away from noise sources such as motors, high-current
switches, transformers, and AC wires.
