Punching Out a Preventive Maintenance Punch List

Next, visually inspect the high-voltage transformer for leaks or dirt. If the transformer is mounted separately from the treat station, inspect the high-voltage wire and standoffs inside the wireway for cleanliness and proper position.

Confirm that the exhaust source for the treating station is functioning properly. The exhaust serves two purposes: it removes ozone and it provides cooling air for the treat roll and electrode. Lack of airflow could cause premature dielectric failure or worse, allow ozone into the work environment. Ozone is very corrosive and could cause damage to other line components in the area of the treating station. If an ozone destruct canister is used, inspect the inlet filters and clean or replace as needed. Dirty filters will restrict airflow and may allow pollutants into the catalyst bed. If the catalyst gets contaminated, it could cost hundreds or thousands of dollars to replace depending on the size of the system.
