Mist Collector P-Trap Maintenance
P-Trap Service
1. Place a suitable container under the P-Trap, turn the collector off and remove the pipe plug.
2. Allow fluid and particulate to drain.
3. Use thread sealant and replace pipe plug.
4. Refill the P-Trap with suitable fluid before restarting the collector.
P-Trap with Y-Strainer, Screen Cleaning and Removal
1. Place a suitable container under the screen clean-out valve, turn the collector off, close the P-Trap valve, then open the screen clean-out valve.
2. Allow fluid and particulate to drain.
3. With the clean-out valve open, slowly open the P-Trap valve. This allows fluid still trapped in the hopper to drain.

Mist Collector Filter Maintenance
Filter Replacement
Most mists present safety and health hazards that require precautions. Wear eye, respiratory, head, and other protection equipment suitable for the type of mist.
Use proper safety and protective equipment when removing contaminants and filters.
Dirty filters may be heavier than they appear. Use appropriate lifting methods to avoid personal injury and or property damage.
Turn power off and lock out all power before performing service or maintenance work.
Do not operate with missing or damaged filters.
First Stage Filter
Remove the first stage filter through the lower access door. Clean the first-stage screen by tapping it gently over an appropriate waste container. If further cleaning is required, wash in an appropriate wash tank. To clean the first-stage filter, soak in an appropriate wash tank, rinse, dry, and re-install.
High temperature, steam-cleaning methods should not be used with the polypropylene filters due to the temperature limitations.
