cure generator to mounts.  
2B-2. Floor Mount Option  
1. Use the 4 1/4"-20 bolts with washers to secure feet  
to bottom of cabinet.  
2. Stand upright and securely fasten to concrete slab  
using appropriate anchors and bolts.  
2C. Electrical  
Main power circuit: Unit is supplied with a standard  
power cord. Plug cord into standard 110V grounded,  
grounding type receptacle only. NOTE: The circuit must  
be protected by a ground-fault circuit interrupter (GFCI)  
installed in accordance with electrical codes.  
2D. Plumbing  
Ozone gas is introduced to the pool circulation line using  
a venturi injector.Suction developed by the venturi allows  
the CD to operate safely under vacuum. See installation  
manual for MX-600-CD for proper venturi installation.  
2D-1. 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 2.  
Figure 2: Plumbing Schematic  
2E. ORP Sensor Connection  
(For optional ORP Controller) Consists of mounting the  
NOTE:The ozone gas supply line must have a back flow  
prevention device (such as a check valve) installed be-  
tween 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 MX-600-CD system.  
ORP probe and routing the sensor cables.  
2E-1. ORP Probe Mounting  
The sensor should be placed in the water stream at a  
point downstream from the ozone injector. See figure 2.  
1. Locate the point of insertion in the process pipe.  
NOTE: Install the ORP probe in a location which  
provides easy access for removal and cleaning of  
the probe.The probe should be installed such that  
the main stream ORP is measured. Locating the  
ORP probe upstream of the ozone measures the  
"pool" water.Locating the probe downstream of the  
ozone measures the ORP of water returning to pool.  
2. Install an appropriately sized tee in the process  
line or drill and tap a 1/2" FPT hole in the process  
pipe as shown in figure 3.  
2D-2. CoolingWater  
Cooling water must be supplied as specified in sec-  
tion 1B.  
1/4" FPT connections are supplied on the generator.  
See figure 2. Be sure that the tubing is appropriately  
matched with the marked inlet and outlet ports.Care-  
fully match and connect to water plumbing as shown  
in figure 2. Alternate method using connections at in-  
jector may be used.  
3. Remove the protective cap and apply Teflon tape  
to the sensor threads. Thread the sensor into the  
fitting or tapped hole. Save the protective sensor  
cap for storage.  
4. Start the circulation system and check for leaks  
around the sensor.

CD-7 thru CD-15 Infinity Corona Discharge Ozone Generator  
Both (2) green indicator lights should be lit. If the optional  
ORP Controller is installed, it should be displaying a read-  
ing from the sensor probe and will automatically cycle the  
generator on and off as needed to maintain water quality.  
A high ORP (650-750 mV) is necessary for biological con-  
trol.  
However, the system will not start under any of the follow-  
ing conditions:  
1. If the optional ORP controller is installed the system  
will not start up if the ORP level is already above  
the setpoint of the ORP controller.  
Figure 3: ORP Probe  
2. The system will not start up if the door is not se-  
cured. A door interlock switch is incorporated into  
the system enclosure.  
3. The system will not start up if there is not enough  
vacuum being generated by water flow through  
injector.Red vacuum light will go out when proper  
vacuum is attained.  
2E-2. ORP Cable Routing:  
Route the cable away from other power wires and protect  
cable from damage. (i.e. Conduit or attached to plumb-  
ing.) Connect the sensor cable to the BNC connector lo-  
cated on the left exterior wall of the generator cabinet.  
4. System will not operate if there is too much  
vacuum. Red vacuum light will go out when  
proper vacuum is attained.  
SECTION 3  
Operation  
If you experience complications, seeTROUBLESHOOT-  
ING section 4C or call 800-676-1335 for assistance.  
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.  
3D. System Shut-Down  
The Infinity Corona Discharge ozone generator is a special-  
ized 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 theOFF”  
position to shut down generator.  
2. Superchlorinate pool water using a chlorine based  
shock treatment.  
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.  
2. After the generator has been shut down, the pro-  
cess water circulation pump may be turned off.  
3. If the system is going to be shutdown and stored  
during freezing weather, it is very important that  
the cooling water jacket be drained to protect it from  
rupture or damage.  
3B. Initial System Start-Up  
Upon completing all of the generator system connections  
and cleaning the pool as outlined above, 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.  
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 gen-  
erator module and electrodes.  
5. Check cooling water.  
6. Adjust injector by-pass to attain required vacuum.  
(Red vacuum light will go out)  
7. Turn main power switch to "ON" position.  
3E. Water Chemistry  
Regular chlorine/bromine testing should be performed as  
normal. Ozone will be eliminating the majority of contami-  
nants. Therefore, only a small amount of chemicals will  
need to be added - just enough to maintain a minimum of  
residual level of .5-1.0 ppm chlorine or 1.0-2.0 ppm bro-  
mine. Ozone has very little if any impact on pH, reducing  
pH adjustments to a minimum.  
3C. Normal Operation  
At this point, the systems cooling fans will start up. The  
oxygen concentrator will begin operating and the output  
solenoid valve will open.The ozone generator should be  
producing ozone and injecting it into the process line.

4A-3. Internal Components  
SECTION 4  
Maintenance and Service  
1. Corona Discharge (CD) Module: Generator  
module consists of stainless steel water jacket  
and ground tubes and two end housings.  
4A. System Electro-Mechanical Overview  
Refer to Figure 4 for component locations.  
4A-1. Indicator Lights  
Enclosed inside the module are the high voltage  
glass tube electrodes.The top end housing (the  
cylindrical glass chamber) encloses the high  
voltage connection for the electrodes and allows  
for visual inspection.  
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 proper vacuum being  
supplied from the venturi injector.Light will be lit for  
either low or high vacuum conditions.  
4. High Coolant Temperature: Red light indicates  
coolant temperature is over 150°F - resulting from  
loss of cooling water flow. (Refer to TROUBLE-  
SHOOTING section.)  
5. HighTransformerTemperature: Red light indicates  
transformer temperature is over 150°F - resulting  
from high current through the transformer.(Refer to  
TROUBLESHOOTING section.)  
6. Water Backflow Detected:Red light indicates wa-  
ter backflow from injector into generator. (Refer to  
TROUBLESHOOTING section.)  
2. HighVoltageTransformer(s):Transformer raises  
supplied voltage up to the voltage necessary for  
ozone production.Transformer is thermally  
protected by a temperature switch attached to the  
transformer casing.  
3. Air Compressor: Compressor produces and  
supplies compressed air to oxygen concentrator.  
4. Oxygen Concentrator: Supplies concentrated,  
dry, oxygen feed gas to the ozone generator.  
5. Lo Limit Vacuum Switch: If the vacuum in the  
ozone output supply line falls below 2 in. Hg the  
switch will open causing the system to shut down.  
6. Hi Limit Vacuum Switch: If the vacuum in the  
ozone output supply line rises above 10 in. Hg the  
switch will open causing the system to shut down.  
7. Water Backflow Detector: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.  
4A-2. Remaining External Components  
1. Main Power Switch:Power switch is used for sys-  
tem 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 gen-  
erator from over current conditions. Push the breaker  
button to reset.  
4. ORP Controller (optional): ORP controller receives  
a millivolt (mV) signal from the ORP sensor mounted  
in the process water line. ORP (Oxidation-Reduc-  
tion Potential) is a measure of the relative oxida-  
tion 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 analyses 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.  
4B. Preventative Maintenance Schedule  
The InfinityCorona Discharge ozone system requires very  
little maintenance beyond general housekeeping practices.  
DAILY:  
1. Check ozone generator for proper operation.

APPENDIX “A”  
SAFETY

CD-7 thru CD-15 Infinity Corona Discharge Ozone Generator  
HEALTH HAZARDS OF OZONE  
FIRST AID  
Detection Levels  
General  
Ozone can be detected in air by its distinctive odor at  
concentrations of about 0.02 ppm. Although each nose  
varies, olfactory fatigue occurs quickly. As a result, DO  
NOT RELY ON ODOR AS AWARNING OF HIGH  
OZONE CONCENTRATIONS.  
First Action  
1. If exposure to ozone causes headache or shortness  
of breath, immediately remove the patient to a fresh  
air environment.  
Second Action  
1. Workers who have been exposed to low concentra-  
tions of ozone should be given oxygen to breathe  
while under the observation of trained personnel.  
2. If exposure is sever, send for medical assistance  
immediately.  
The permissible exposure level (PEL) or time weighted  
concentration for ozone to which workers may be  
exposed os 0.1 ppm averaged over 8 hours, 5 days a  
week (OSHA).The short term exposure limit is 0.3 ppm  
average over 15 minutes.The concentration of 10 ppm  
ozone in air is generally accepted as immediately  
Dangerous to Life or Health (DLH).  
Inhalation  
First Action  
Effects on Humans  
1. Assess patient's breathing.  
2. All unconscious patients must be placed in the  
drainage position (on their sides), so that fluids can  
drain from the airways once breathing has been  
restored.  
3. Check pulse.  
Second Action  
1. If breathing has ceased, start artificial respiration  
(rescue breathing is the most effective) method until  
breathing has been restored.  
Ozone acts as a primary irritant, affecting mainly the  
eyes, upper respiratory tract and the lungs. Onset of  
pulmonary edema (fluid buildup in the lungs) may be  
delayed for a few hours after exposure. Inhaling ozone  
at concentrations of 50 ppm for 30 minutes can be fatal.  
Many people exposed to airborne ozone rapidly develop  
a headache, which often disappears after a few minutes  
in fresh air.  
2. Send for medical assistance immediately.  
3. If absent, begin cardiopulmonary resuscitation  
(CPR).  
Reduction in lung function due to scar tissue forming in  
the lung may occur due to long-term exposure to ozone  
at concentrations above 0.2 ppm, or a single high  
exposure. Although medical studies show no evidence  
of ozone causing cancer or lung allergies or harming the  
unborn, there is some evidence that the oxidizing power  
of ozone could lead to premature aging of the body as a  
whole.  
Eye Contact  
First Action  
1. Effective irrigation should start immediately. Eyes  
should be irrigated for 30 minutes by the clock with  
running tap water or preferably normal saline.  
Second Action  
1. Effective irrigation must be continued while en route  
to hospital.  
The owner of any ozone installation should advise any  
person who may be exposed to ozone that those with a  
history of heart or respiratory disease should take every  
precaution to avoid exposure to ozone.
