Donaldson Torit Mist Collector WSO 25-3

Suitable container placed under the P-Trap

Thread sealant used and pipe plug replaced

P-Trap refilled with suitable fluid

Place a suitable container under the screen cleanout valve, turn the collector OFF, close the P-Trap valve, then open the screen clean-out valve.

With the clean-out valve open, slowly open the P-Trap valve. This allows fluid still trapped in the hopper to drain.

NOTICE: A substantial amount of fluid may be trapped in the hopper and could exceed the container capacity. Open the P-Trap valve slowly.

Unscrew the screen cap and pull the screen out.

Screen and inside of the Y-strainer body cleaned and re-assembled?
