PREVENTIVE MAINTENANCE

PM Schedules

Power Supply

Every maintenance log indication, or every 500 hours on analog units
1.Ensure fans are not clogged with debris and proper airflow is achieved
2.Verify debris buildup is not occurring around heatsinks
3.Blow heatsinks off with compressed air every 500 hours. Heat is the #1 cause of semiconductor failure

Treatment Station

Every maintenance log indication, or weekly if running 24/7 (160 hours)
1.Clean electrode faces with isopropyl alcohol. Use compressed air to loosen debris around the assembly and mounting blocks
2.Verify cooling slots are free of debris. Clear any buildup to ensure proper airflow and dielectric cooling
3.Clean ground roll face with isopropyl alcohol. Do not run the treater while roll coating has any moisture or residue from cleaning

INSTALLATION GUIDES

How to Install Consumables

Installing Ceramic Electrodes

1.Trim electrode wire to desired length
2.Ensure high voltage wires do NOT touch metal or control wires—maintain 1.5″ clearance minimum
3.Seat electrode properly in the mounting block
4.Re-gap electrodes to 0.060″ using the provided gap gauge
IMPORTANT
Do not allow electrodes to rub on the roll surface. Keep ceramic clean and free of plastic, glue, or contaminants. Ensure cooling holes remain clear of debris. Do NOT use nylon screws—contact us for high-temperature/high-dielectric screws.

Installing Silicone Sleeving

Requires two people. Keep working area and sleeve surface clean.
1.Place roll in vertical position on floor or bench
2.Slip open end of sleeve over upper end of roll by 2–3 inches
3.Insert high-pressure air nozzle between sleeve and roll
4.Assistant slowly opens air valve while you hold sleeve firmly
5.As sleeve fills with air, pull it down over full roll length
6.Sleeve should project over roll face at least 1″ on both ends

Installing Control Boards

1.Connect the top ribbon header to the bottom cable connector on the circuit board
2.Connect the bottom ribbon cable header to the top ribbon connector on the new control board
3.Verify installation
KEY
The ribbon cables crisscross when installed correctly.
Lost or need a replacement electrode gap gauge? Contact us and we’ll send a replacement free of charge.
CLEANING PROCEDURES

Cleaning Your Corona Treater

Routine cleaning every 500 hours of operation extends the life of your electrodes, rolls, and overall system performance.

Ceramic Electrodes

Use lint-free rags and isopropyl alcohol to wipe down the entire assembly. Scotch Brite pads can be used gently on the electrode to remove buildup. Clean every 500 hours of operation. Work it into your schedule during job changes or downtime.

Ceramic Coated Rolls

Wipe the surface with lint-free rags dampened with an appropriate solvent: isopropyl alcohol (IPA), MEK, naphtha, or TCE. Do not run the treater until the roll surface is completely dry and free of residue.
