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.
SECTION 3
Operation
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.
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
begin start up procedures.
1. Check electrical fittings.
2. Check for proper voltage.
3. Turn on circulation pump.
4. Check for leaks.
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.
3C. Normal Operation
At this point, the system’s 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.

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.
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.
4. System will not operate if there is too much
vacuum. Red vacuum light will go out when
proper vacuum is attained.

ING section 4C or call 800-676-1335 for assistance.
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 the “OFF”
position to shut down generator.
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.
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.
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.
