Option 2 – Odour filter fitted directly to the waste tank (Not Recommended)

  1. Insert 5/8 (16mm)  hose tail into rubber seal in top of tank.

  2. Place breather hose onto hose tail at the other end of the filter.

Caution: Make sure not to over fill the waste tank, as this will water log the filter and the filter will no longer work. Replace the odour filter if it gets wet.
