3.0 Maintenance
The AIM Series Ozone Generator is designed and delivered for maximum efficiency and long
life. No adjustments, other than fine-tuning the airflow 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.
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 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.
3.1 Corona Discharge Cell Maintenance
Corona discharge cell maintenance is simply a matter of keeping the cells clean and ensuring the
O-Ring seat is in good condition. AIM BTU 2000 units will have two (2) cell chambers to maintain
while AIM BTU 1000 units will have one (1) cell chamber. Ozotech, Inc., has designed a cell-to-
chamber interface that restricts the corona discharge to only the stainless steel manifold, thereby
reducing any possibility of catastrophic failure due to heat or high voltage arcing.
Frequency of Maintenance:
Every 4800 hours (6 months)
To maintain the Corona Discharge Cells:
1. Disconnect unit from power source. Allow generator and room to clear of ozone gas.
2. Loosen the four (4) screws securing the chassis lid and remove the lid assembly.
3. Locate the high voltage wires connected to the top of each corona discharge cell. Pay close
attention to the wire routing. It will be necessary to route in the same manner when
maintenance is complete.
Note: In any case, wires must be routed so that a minimum clearance of 1 inch is provided
between HV wire and chassis (or metal parts attached to chassis).
4. Unplug the CD cell cap high voltage wires from the transformer high voltage wire.
(See Figure 1)
5. Carefully loosen and remove each of the six (6) nylon standoffs that secure the cap(s) onto the
manifold. Pull each CD cell cap straight off the mounting studs. (See Figure 2)
6. Very carefully remove the CD cell(s) straight out of the manifold assembly. (See Figure 3)
Note: Your corona discharge cells are made of glass, so extreme care must be taken to avoid
breakage!
7. Clean the entire cell and cap with glass cleaner, or soap and water.
DRY THOROUGHLY.
Note: Replacing a wet cell will cause damage to the ozone generator.
8. Install the corona discharge cell(s) by reversing the above steps.
a. Route high voltage wires as close to original routing as possible.
b. The object is to separate these wires from sources of ground, such as the chassis, and
low voltage (115 or 230V) components.
