2.0 Installation and Operation

Your generator requires special operating conditions in order to maintain performance and reliability. Your ozone generator is designed to be operated under a negative pressure situation.

Warranty coverage of your equipment is contingent upon strict compliance with the operating conditions specified in this manual.

2.1 Operating Environment
External
It is most important to choose a cool, clean external operating environment.
Consideration of these factors should be a priority. Mount your ozone generator in the best possible operating environment that is available at the chosen site. If possible, mount in an area that is free of airborne moisture particles.

Internal
Keep the inside of the generator chassis clean and dry. Dust particles and condensation pose a challenge to the consistent operation of all ozone generators.

2.3 Operation

The EOG with air dryer will automatically turn on and off by the Clack® control PCB defined timing schedule. The EOG control board utilizes an on- board diagnostic LED light to convey real-time status of the unit. The control board within the EOG has several inputs and outputs. The following key addresses the various LED statuses regarding the operation of the EOG.

LED Light Indicator Key:
Green Light Blinking Slowly: Standby mode; unit is powered, pilot input is OFF.
Green Light Blinking Quickly: High voltage startup (up to 3 seconds).
Green Light Solid: High voltage is ON & stable; CD cell(s)producing ozone.
Red Light Solid: Unstable operation; CD cell may need cleaning.
Green/Red Light Alternating Twice/Second: HV is ON, but operating current is low. If persistent, CD cell(s) may need cleaning.
Red Light Flashing: NO or NC contacts are shorted. Remove short condition.
Orange Light: 1-year timer has expired; clean CD cell(s), then reset timer by pressing red “alarm reset” button on PCB once.

Control Input:
The EOG with air dryer PCB is activated to produce ozone when a pilot input signal is applied across “+” and “pilot” terminals.

Auxiliary Outputs:
The NO/NC auxiliary outputs have a 3 second on and off-delay, after the pilot signal is activated or deactivated. These outputs are capable of providing a maximum of 60mA @ 70°F and are intended to be used as a control circuit only.

Fusing:
The control PCB is equipped with automatically resetting on-board fuses. If these fuses trip, due to a short of the HV transformer, or an excessive load on the auxiliary output(s), remove the excessive load/cause of short, and cycle main power on/off to reset. If the HV transformer is shorted, the LED indicator will stay solid red until the condition is remedied. If either NO or NC output is active and experiences excessive load, the LED indicator will quickly flash red until the condition is removed.

3.0 Maintenance

The EOG ozone generator with air dryer is delivered factory tested, calibrated, and adjusted for maximum efficiency and long life. Simple maintenance and appropriate operating conditions are the only requirements to keep the unit functioning within manufacturer’s specifications.

Performing any other modifications or adjustments to internal components will cause the unit to function outside of manufacturer’s specifications and will cause damage to the unit not covered under warranty terms.

3.1 Ozone Generator Maintenance
Frequency of Maintenance:

Every 12 months, more frequently in high humidity areas.

Perform the following general maintenance procedure:

1. Disconnect the EOG with air dryer from the power source.
2. Remove cover.
3. Inspect the inside of the generator for dust and moisture.
4. Thoroughly clean and dry the inside of the generator.
5. Replace top cover.
6. Replace any in-line and brine elbow check valves.

Normally the EOG with air dryer controller board will signal cell maintenance after one year of service by changing the LED indicator light to orange. Once service has been performed, the timer can be reset by following the timer reset instructions below. However, if the cell is serviced or replaced prior to the oneyear service signal, a “forced reset” on the timer should be performed.

3.2 Maintenance Timer Service Reset Instructions:

Follow these instructions to perform a reset on the EOG board:

1. Disconnect power from the EOG with air dryer.
2. Press and hold reset button while re-powering the EOG.
3. Pulsing orange LED will indicate timer rest function is active.

• Press reset button again to complete reset. LED will pulse green when finished. 4. The EOG with air dryer is now ready to operate as normal.

Notes: This feature only applies to EOGs manufactured after May 2020 (See program rev code on side of transformer and/or date code in serial number).
To abort the timer reset once timer reset function is active (pulsing orange), disconnect then reconnect power without pressing any buttons.

3.3 Cleaning the Corona Discharge Cell

CAUTION: UNPLUG POWER SUPPLY TO EOG BEFORE PERFORMING SERVICE

1. Disconnect the cell from the unit by removing cell-to-board electrical connections and the CD cell from it’s mounting clips. Remove the tubing from the cell barbs.

2. Connect the longer piece of clear tubing from your cleaning kit to one of the cell barbs. Attach the shorter piece of clear tubing from the kit to the open CD cell barb. Insert the tubing adapter, attached to the syringe, into the open end of the short piece of tubing. Fill the beaker included in your kit with warm water. Place the open end of the long clear tube into the beaker. Now you’re ready to flush the cell. Note: Hot water can be used if nitric acid buildup is severe.

3. Flush water through the cell by pulling back and pushing the syringe plunger. Water may become cloudy or discolored as the nitric byproducts are released from the CD cell during flushing. Discard and replace warm water in the beaker as cloudiness continues. Flush the CD cell until the water is clear.

4. Remove both pieces of tubing from the CD cell barbs. Dry the cell using the can of compressed air supplied in your kit. Place the nozzle of the compressed air into one of the barbs of the CD cell. Depress the trigger on the can to dry the cell until all moisture is evacuated from the cell.

3.4 Replacing a Corona Discharge Cell

CAUTION: UNPLUG POWER SUPPLY TO EOG BEFORE PERFORMING SERVICE

1. With the cover of your specific unit removed, remove the CD cell from the ozone generator:
a. Disconnect any electrical connections between the CD cell and the electronics board.
b. Remove and discard any shipping ties that may be securing the CD cell(s).
c. Disconnect the air inlet and ozone outlet hoses from the CD cell barb fittings.
d. Pull the CD cell straight up from the retaining clips.

2. Replace with a new CD cell in reverse order, making sure all air and electrical connections are secure.

3.5 Determining When to Replace the Desiccant Media
1. The easiest way to determine if the desiccant media needs to be replaced is to open the cover of the EOG with air dryer and examine the clear tubing going into the CD cell. If water droplets are present, the desiccant media is saturated and needs to be replaced.
2. Another method is if your EOG board is showing a constant red light warning.
3. In extreme cases, you may notice water dripping from the bottom of the desiccant media protective cap.
If any of these conditions occur, replace the desiccant media as soon as possible. (See replacement parts for the part number for the replacement kit.)

3.6 Replacing the Heater Bed Desiccant Media

CAUTION: UNPLUG POWER SUPPLY TO EOG BEFORE PERFORMING SERVICE

1. Remove the control wire from the control panel.
2. Remove the EOG with air dryer from the tank valve.
3. Remove the heater media protective cap.

4. Using a pair of snap ring pliers, carefully remove the retaining ring.

5. Empty the used desiccant media into a container and retrieve the mesh screen.

6. Notice the heater element. Using a funnel, pour the new desiccant media halfway up the heater element, then center the element in the heater using a pencil tip.

7. Continue filling the desiccant media to just over the retaining ring groove and set the mesh screen on top. Gently tap the heater body to settle the media until the screen is just below the retaining ring groove.

8. Carefully insert the retaining ring and reattach the heater media protective cap.
