2 Weeks After Startup
1. Inspect the unit and duct for grease or air leaks and repair leaks where required.
2. All fasteners and hardware should be checked for tightness each time maintenance checks are
performed prior to restarting unit.
3. Monitor filter loading and determine the frequency that filters should be replaced. This will vary
with the amount of contaminated effluent being filtered. Airflow will be affected (reduced) by filter
loading. It is important that the pre-filter be cleaned on a regular basis and that the remaining
filters be replaced when necessary to keep design airflow requirements.
4. Make necessary adjustments to air pressure switch to ensure proper function of indicator light.
Every Month
1. Inspect the unit and duct for grease or air leaks and repair leaks where required.
2. Filters need to be checked monthly for loading. If required, the filters either need to be cleaned or
replaced. Filter change out may occur more often in severe conditions. Washable steel pre-
filters can be washed in warm soapy water. When re-installing filters, be sure to install with the
airflow in the correct direction as indicated on the filter or with drain holes on bottom edge of
filter.
Duct Cleaning
1. Place tarp under PCU to catch overspray during cleaning.
2. Place tarp over Blower insulation and motor to prevent damage during cleaning.
3. Remove all tarps from Unit after cleaning is completed.
Yearly
1. Inspect all seals for wear and deterioration. Replace if necessary.
2. Inspect pre-filter for cleanliness. Replace if necessary.
3. Replace all secondary filtration and odor control media if necessary.
4. Inspect unit for leaks where ductwork is attached and in modules themselves. Repair where
necessary
