Use proper safety and protective equipment when removing contaminants and filters.

First Stage Filter Cleaning and Installation

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.

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.
