2.0 Theory of Operation

Your AIM P7 ozone generator is a state-of-the-art device designed to produce a significant amount of highly concentrated ozone by means of our proprietary Advanced Impedance Management technology, "AIM". The technology utilized by Ozotech, Inc., to generate ozone is known as "Plasma Discharge".

By supplying a high purity oxygen feed gas through the ozone generator, along with the proper amount of back pressure applied, concentrations above 2% by weight, (or an output of around 7 grams per hour). Your AIM P7 generator will come pre-set to operate in "Manual Ozone Adjustment" mode. This means that after installing your AIM P7 ozone generator, simply turning the "Ozone Enable" switch to "Ozone ON".

The "Manual Ozone Adjustment" knob can be adjusted to dial the % of power you want the generator to run at. This will be shown on the "Power Display". If you are planning on running the system with a 4-20mA, 0-10VDC or a 0-5VDC (0-10mA maximum) external signal, you will need to remove power at the source of the unit and run the appropriate signal cables to the "External Signal Port" terminal block.

Replace the lid and reestablish power. Move the "Ozone Enable" switch to "ON". If using a remote signal turn the "Signal Input" switch to "Remote Signal". You can now use your controller to operate your generator.

2.1 Plasma Discharge Ozone Generation

Plasma discharge generators create ozone through the action of high voltage, low current electrical "arcs" across an air space. When oxygen (O2) is passed through the air space, some molecules are split, resulting in "free" oxygen atoms which quickly attach themselves to intact O2 molecules.

The result is a very unstable form of oxygen, O3 (ozone). It is the extra atom of oxygen that gives ozone its superior oxidation capabilities. Unlike other oxidants, such as chlorine and hydrogen peroxide, ozone reverts back into oxygen over time making it an environmentally friendly oxidizer.

3.0 Operating Conditions

Your AIM P7 ozone generator requires special operating conditions in order to maintain performance and reliability. Warranty coverage of your equipment is contingent upon strict compliance with the operating conditions specified in this manual.

3.1 Operating Environment

External

Choose a location for your equipment that is clean, dry, and free of excessive airborne particles. Your equipment requires a constant flow of clean air for proper internal cooling. A minimum of six (6) inches clearance is required around the front, bottom, left and right sides of the unit to eliminate restriction of air flow. Direct exposure to moisture must be avoided. The AIM P7 ozone generator chassis is designed to be drip-proof. It is not watertight.

Mount your AIM P7 ozone generator in the best possible operating environment available at your installation site.

Internal

The operating environment inside the chassis is also important. Maintaining a clean, dry unit will increase overall performance and extend service life. A common cause of failure is un-contained corona (electrical arcs) within the chassis environment. Moisture and dust are facilitators of this condition. They both help create a "path" for the plasma to develop and follow. Once established, the plasma usually does not stop until it has become severe enough to cause catastrophic failure of the plasma discharge, and subsequently blows the fuse. Note: If this condition develops, contact the manufacturer.

3.2 Internal Air Flow Specifications

As mentioned in the Theory of Operation section, plasma discharge relies upon a flow of high purity oxygen passing through the ozone generator.

The rate at which air is drawn (or forced) through the ozone generator is user adjustable. You may fine tune the flow rate to best suit your specific application. However, in no case should the air flow rate be allowed to drop below the minimum values specified below. Failure to provide minimum air flow rates may allow your ozone generator to develop too much heat, possibly leading to equipment failure.

3.3 Preparation of Input Air

Regardless of the method of ozone generation, properly preparing the input air (feed gas) will pay huge dividends in performance and reliability. Ozotech, Inc. does not recommend the use of any AIM P7 ozone generator without air preparation. Warranty coverage of your ozone generator is contingent upon operation with air preparation equipment.

The key to air preparation is in the removal of Hydrogen (H) and Nitrogen (N) found in ambient air. When atoms of Hydrogen and Nitrogen are subject to plasma discharge, by-products such as Nitrous acid (HNO2) and Nitric acid (HNO3) are formed. The formation of these compounds inhibits performance and increases the frequency of maintenance.

To understand how performance is affected, we must recall from the Theory of Operation section that ozone is created by splitting an oxygen molecule (O2), and then joining the liberated oxygen atoms (O) with intact oxygen molecules.

Imagine that in addition to oxygen molecules, your feed gas also contains Hydrogen and Nitrogen atoms. After being subjected to plasma, some of the Hydrogen and Nitrogen atoms will attach themselves to intact oxygen molecules, forming HNO3, or Nitric acid. Others will attach themselves to ozone molecules, forming HNO2, or Nitrous acid. It is the formation of these compounds that reduces performance potential. It is simple to understand why. If ozone molecules were not being "used" by Hydrogen and Nitrogen in the formation of acids, more would be available to be used in oxidation. Likewise, if oxygen molecules were not "used" to form acids, they would be available for the creation of more ozone.

Increased service life and reduction in maintenance are gained due to the same principle. With less HNO2 and HNO3 being formed, plasma discharge maintenance can be reduced without the risk of acid buildup. Since both HNO2 and HNO3 are highly conductive, they are capable of producing a path for corona (electrical arcs) inside of the Plasma block. As stated previously, once an arc has started, catastrophic failure is the usual result.

Your AIM P7 ozone generator must be used with a positive pressure air preparation device. Negative pressure devices, such as heat-regenerated desiccant air dryers rely upon the action of the venturi injector to draw air through the generator (and the dryer). This method is not utilized with the AIM P7 generator, due to it introducing moisture laden ambient air. Positive pressure devices, such as the ProO2 or AirSep series oxygen concentrators utilize an internal air compressor to push prepared air through the generator.

Your AIM P7 generator is designed for not more than 50 psi of internal pressure.

3.4 Input Power Requirements

The AIM P7, powered by 115 or 230VAC at 50/60Hz, accommodates a wide range of world supply voltages and frequencies. It is extremely important that your equipment is provided with the appropriate operating power source. Most supply voltages fluctuate, so it is necessary to monitor your voltage and assure it is within acceptable variance values listed below.

4.0 Maintenance

AIM P7 generators are designed and delivered for maximum efficiency and long life. No adjustments, other than fine-tuning the air flow rate to match user-specific requirements, should be made by the end user. Simple maintenance and appropriate operating conditions are the only requirements to keep the unit functioning within manufacturer's specifications. There must be at least 5psi of back pressure applied when operating the AIM P7 generators. This is accomplished by using the labeled "back pressure adjustment" control knob located on the front of the generator.

Performing any other modifications or adjustments to internal components will cause the unit to function outside of the manufacturer's specifications and will cause damage to the unit not covered under terms of warranty. Maintenance should only be performed by qualified individuals. Your ozone generator operates under conditions of high voltage; maintenance personnel should be trained in electrical safety.

4.1 Plasma Block Maintenance

AIM P7 plasma generators are completely intrinsic modular units, with no user maintenance involved. If at some point a noticeable decrease in ozone production presents itself over time, moisture has most likely accumulated inside the plasma block causing a build up of nitric acid. If this should occur perform the below procedure.

Plasma Block Nitric Acid Removal Process

Procedure for removing nitric acid build-up, referencing the Air Inlet & Ozone Outlet Ports (Figure 1).

1. Disconnect all power from the AIM P Series generator at its source.
2. Disconnect the "Air Inlet" and "Ozone Outlet" lines from the Plasma Block itself.
3. Connect customer supplied tubing lines, (3/8" ID PVC tubing), to the Plasma Block inlet and outline ports.
4. Run isopropyl alcohol from the air inlet line until it starts to exit the ozone outlet line.
5. Work the alcohol back and forth through the Plasma Block.
6. Discharge the alcohol through the ozone outlet port until the alcohol exits clear, and free of any yellow/brown tinge indicating nitric acid.
7. Reconnect the generator's original "Air Inlet" and "Ozone Outlet” lines.
8. Operate the oxygen concentrator or bottled oxygen through the generator for approximately 10 minutes to ensure the alcohol is cleared out of the Plasma Block prior to reapplying power to the unit.

4.2 Intake Filter Maintenance

The intake filter is located on the side of the chassis, as shown in the Chassis Component Details (Right Side) (Figure 2). This filter removes dust particles from the air drawn into the chassis. Proper cooling of internal components requires filters to be clean, dry, and intact.

1. Remove the top inside screws of the louver.
2. Loosen, but don’t remove the bottom two screws of the louver.
3. Remove the intake filter from behind the louver.
4. Clean or replace the intake filter as needed.
5. Install intake filter in reverse order.

Frequency of Maintenance:

• Every 2,190 hours = 3 months (730.485 hrs. /month)

To Clean Intake Filter:

• Remove filter media. Wash gently in soap and water. Dry thoroughly. Inspect for tears, holes, etc. If the filter is intact, replace by reversing the previous step.

Note: Depending on the severity of your specific environment, it may be necessary to increase frequency of maintenance.

Frequency of Replacement:

• Every 4,383 hours (6 months)

To Replace Intake Filter:

• The replacement procedure is identical to maintenance procedure.

Note: Depending on the severity of your specific environment, it may be necessary to increase frequency of maintenance.

4.3 Chassis Maintenance

Proper maintenance of your generator chassis will provide more than aesthetic advantages. Dust and moisture can contribute to a path for electrical arcs. A clean internal environment will reduce the likelihood of corona outside of the plasma block.

Frequency of Maintenance:

• Every 2,190 hours (3 months)

To Maintain Chassis:

• Disconnect unit from power source.
• Remove chassis lid.
• Using a clean, dry cloth, carefully wipe out the inside of the chassis and all internal components to remove any dirt or debris. Use a low pressure (≤20 psi) stream of compressed air or a can of compressed air to blow dust from electrical components.
• Using a damp cloth, clean the outside of the unit. A mild detergent may be used.
• Thoroughly dry chassis, inside and out.

4.4 Check Valve & Vacuum Prevention Device Replacements

We strongly suggest that tall check valves and vacuum prevention devices are closely inspected as often as possible, such as each time maintenance of any type is performed. If water is visible between the check valve and the ozone generator, cracks are visible in the check valve body, or foreign matter has built up on the internal O-ring, replacement should be performed immediately, regardless of elapsed time since last replacement.

The minimum required replacement schedule is listed below, and must be performed on schedule, even if the check valve appears sound to maintain warranty terms.

Frequency of Replacement:

• Every 6 months

To Replace Check Valve

Referencing Check Valve Replacement (Figure 3).

1. Disconnect unit from power source.
2. Allow the ozone generator to clear of ozone gas.
3. Remove tubing from check valve barb fitting on both sides.
4. Trim approximately one inch from the end of each tube, to remove distortion caused by the barbed adapter.
5. Place new check valve assembly in-line, between ozone generator and venturi injector. Check valve flow direction must point toward the venturi.

Frequency of Replacement:

• Every 12 months
