Installation Instructions
Ozone Generator Placement
• Install the SP Series in a clean, dry area with good ventilation.
• Select a location for the ozone generator that is as close as possible to the ozone
injection point.
• The SP Series enclosure is not rain proof, so it is important to choose a location that will
keep the system away from direct weather and excessive heat.
• The ozone generator should be placed above water level because if pressure is lost in
the venturi vacuum, gravity will cause water to travel down the ozone output tube and
enter into the ozonator.
• Situate the unit in a manner suitable for convenient electrical access.
• Mounting holes are located on the back of the ozone generator for convenient wall
mounting (mounting hardware is not provided).
• The basic installation method for the SP Series system is through a venturi injector
manifold plumbing connection.
• The venturi Injector manifold must be assembled (venturi injector is sold separately).
NOTE: Be sure to place the ozone generator in temperatures 40 and 100 degrees
Fahrenheit (4.5 to 38 degrees Celsius).
Venturi Injector Installation
A typical venturi injector manifold
• Refer to the Venturi Injector Installation diagram and follow the instructions below if the
ozone is being injected directly into the full flow of the pool’s return line:

8
• Identify the pool water return line after the pump, filter and heater, then tap into this
point.
• The ozone injection point should be the last component in line and as far as possible
from the injection point of the residual chemical.
• Glue in the proper injector manifold, noting the direction of flow which is indicated by an
arrow on the injector.
• Once the injector is installed, the vacuum may be adjusted as described in the Operating
Instructions section.
Details of Venturi Injector Manifold
• Install the venturi injector with a bypass valve on the water return pipeline.
• The arrow on the venturi injector manifold MUST be set as the same direction as the
water flow.
• Turn the water pump on and close the bypass valve until the vacuum is created at the
venturi input.

Flow from pool

• Use the installed flow-meter to check vacuum for -2 to -3 PSI (-0.14 to -0.21 bars) or
place finger over the end of the venturi valve to feel the vacuum while adjusting the
bypass venturi valve.
• As ozone is injected into the water line, air bubbles should be observed in the water of
the swimming pool.
Diagram
Main Power
• Use the power cable provided to connect the SP Series to a properly rated and grounded
receptacle.
• If the ozone generator will be used where water is present, a ground fault circuit
interrupter must protect the circuit.
Tube Connection and Start Up
• Connect a silicone tube (if using an oxygen generator, oxygen tank or external air
compressor) to the SP Series unit (Air In) and direct it away from any hot and humid air
towards the ozone cell.
• This will serve as oxygen or fresh air for ozone production.
• Connect the ozone generator PTFE tube (Ozone Out) to the venturi injector manifold.

Check Valve

• Install a check valve 10 inches after the ozone outlet tube fitting (the venturi has an
internal check valve).
• This can be done by cutting the tube ten inches after ozone out fitting.
• Next, connect both ends of the cut tubes to the check valve.
• Please direct the arrow on the check valve toward the venturi injector.
• First, start up the swimming pool water recirculation pump.
• Make sure there is a vacuum at the venturi injector via a gauge and test it by putting
your finger on the venturi injector opening.
• A small suction should be felt at this injector opening. This is what is needed to get the
ozone production out of the SP unit and injected into the pool’s piping system.
• Check that the flow meter indicates that the air flow is at least 2 LPM.
• Now connect the PTFE tube from the venturi to the ozonator.
• Turn on the power on the external panel of the ozone generator.
• The ozone indicator light should illuminate and the unit’s fan should turn on.
• Increase power to the cells by turning the ozone control knob clockwise.
• Please refer to the charts above for the approximate ozone concertation for you size of
pool.

Operating Instructions
System Run Times
On residential pools, the ozone generator should operate for six to eight hours per day.
Normally, the ozone system will run whenever the pool filtration system is operating. Since
commercial pool and spa filtration systems normally operate 24 hours a day, the ozone
system will run continuously on a commercial pool.
Understanding Your Water
If a high concentration of any mineral (such as calcium or iron) exists in the water, it is
necessary to treat it before starting the ozone system.
NOTE: This should be required only when the pool is drained and refilled.
If the water is clean and clear, the ozone system may be started immediately. If the water
is dirty and cloudy, it is recommended that it is drained and the filers thoroughly cleaned
before refilling and starting the system.
NOTE: It is not recommended that an in-ground pool be drained in the winter or after the
first rain of a season. Use a shock treatment instead of draining to avoid the possibility of
severe damage resulting from “floating” the pool out of the ground.
Ozone and Bromine
Ozone has a short half-life which means it dissipates and re-transforms into oxygen very
quickly. Therefore, a small residual of another disinfectant must be maintained. We
recommend the use of bromine in indoor pools. Bromine residual will act as a buffer
when the ozone system is not operating. Bromine needs to be maintained only 1.0 PPM
(Parts Per Million) so that the trace amount of the product in the water will not be noticed.
Chlorine will also work as a residual oxidizer and may be used effectively in conjunction with
the ozone system.
Ozone and Chlorine
For outdoor pools, we recommend the use of chlorine to supplement the ozone. Chlorine
residual will act as a buffer when the ozone system is not operating. Chlorine needs to be
maintained at 1.0 to 2.0 PPM (Parts Per Million).
11

Water Preparation
To properly prepare the water for the ozone system, make the following adjustments and
maintain the levels outlined below:
Bromine 1.0 PPM
Chlorine 1.0 to 2.0 PPM and pH 7.2 to 7.6
Total Alkalinity 100 to 150 PPM
Calcium Hardness 200 to 350 PPM
NOTE: If any unusual reactions are experienced when ozone is introduced into the water
(such as abnormal color or odor), please wait a few days to give the ozone and filter system
time to work.
Algae
Always maintain the recommended residual levels of bromine or chlorine (at least 1.0
PPM) to help control algae formation. Brushing the poolside once a week is also effective.
Additionally, using an algaecide is effective.
Shock Treatment
If an unusually high bather load causes cloudiness in the water, it is recommended that
a chlorine shock treatment be used to assist the ozone in cleaning the water. Routine,
periodic shocking is recommended to prevent buildup of organic contaminants, especially
with indoor pools.

Maintenance
Clean Air Filter
This filter must be cleaned regularly. Depending on the location of the unit, it may be
necessary to clean the air filter monthly. The filter elements are located on the bottom of
the cabinet (see illustration below). This is the air intake element for the cooling fan and
may therefore require the most frequent cleaning. The element may be cleaned with soap
and water and should be dried completely before reinstalling. Clean this filter regularly.
Failure to do so will promote overheating and void the warranty.
NOTE: In a clean environment, this procedure may only need to be performed every three
months.
• Turn the SP Series ozone generator off.
• Clean the filter screen with water and soap.
• Dry the filter with a clean towel.
• Install the screen back onto the unit.
• Turn the ozone generator on.
• Be sure the unit’s screen does not touch fan blade.
Swimming Pool Filter
Ozone will keep the water much cleaner than any other type of water purification system.
This is due to the fact that ozone neutralizes body oils and soaps. After ozone kills the
bacteria, the byproducts of the process are oxygen, carbon dioxide and filterable solids.
Since filterable solids are usually higher levels with conventional disinfection processes, the
filter will have more work to do. Keeping the filter clean will make a noticeable difference
in the clarity of the water. It is recommended that a regular filter cleaning schedule is
established, or poor water flow through the filter will result. This will have a direct effect on
the amount of ozone that enters the water.
CAUTION: There is extremely high voltage inside the ozone generator. If you suspect a
problem, disconnect the power to the unit at the service disconnect box or main electrical
panel and immediately contact your swimming pool maintenance technician. Inspect the
ozone delivery line check valves daily for water seepage an strongly recommend replacing
the injector check valve yearly.
17

Check Valves
Two check valves are available for the ozone delivery system. One where the ozone tubing
attaches to the ozone generator and one where it attaches to the injector. The purpose of
these check valves is to prevent water from backing up into the ozone generator. The PTFE
ozone delivery line(s) should be inspected daily to ensure water is not flowing back into the
ozone generator. Check valves should be replaced yearly.
NOTE: The only time it is possible for water to flow back toward the ozone generator is
during a system shutdown. Always inspect for water seepage during this time.
Fuses
Fuse is located on the panel at the bottom of the unit. The fuse is 3 AMP for SP-3G to SP-8G
and 6 AMP for SP-16G.
18

Troubleshooting
The test method for failure of the ozone generator:
• Check the power input for correct voltage (110V or 220V)
• Unit is on, but no ozone; this is due to overheating or water back flow to the ozone
generator.
• Turn off ozone generator and let air flow through the unit for 1 to 2 hours to dry the
ozone tube.
• Check the main fuse, change if needed. It is a 3 AMP for SP-3G to SP-8G and 6 AMP for
the SP-16G fuse.
• Check the tubing inside the machine for kinks.
• If the machine can produce some air, but the air is not ozone; please check the
following:
• The power indication lamp is lit.
• Check ozone control knob is set above zero.
• Check ozone board fuse, 3 AMP.
• Check wire from terminal to ozone board.
• Check pot wire is connected to ozone board.
If you are still experiencing problems, please contact A2Z Ozone for more information.
