Trace amounts of mild nitric acid may be present in
the Ozone Outlet Manifold and Tubing. Handle plumbing
carefully and wear proper protective equipment.
• Remove each of the Air Inlet Filters from the Ozone Generator Assembly.
• A syringe and tubing is provided with the Cleaning Kit. Connect the
tubing to one barb of the Ozone Cell and run it to a suitable recovery
container (glass, ceramic or metal is ideal).
• Place the tip of the syringe rmly into the opposite Ozone Cell barb
while supporting the cell with the other hand. Slowly push the acetone
through the cell and tubing into the recovery container. Flush each cell
with approximately 12 mL of acetone (equal to about a 1.5” inch length
in the syringe provided).
WARNING
Acetone is ammable. Follow safety and handling
instructions on the container.
• Once all cells have been ushed, allow several minutes for excess
acetone to evaporate then reattach the Ozone Manifold and Air Inlet
Filters.
• Leave the DEL AOP 50 disconnected and run the pool circulation
system. Allow fresh air to be pulled through the cells for 10 minutes.
• Close or reattach the DEL AOP 50 cover and reconnect power.
