This BrewZilla Sight Polycarbonate Sight Glass also comes assembled with clamps. 

1. To remove your stainless steel sight glass, start by removing the two screws that mount the top section of the recirculation tube.
2. Then using a spanner *not included* loosen and remove the bottom 1/2" female fitting.
3. There is a small white washer underneath. Move that to the side as it will be needed later for the upgrade!
4. Swap over the camlock fitting

*please note you may need to use varying amounts of thread tape to get it to seal in the right position once it has been tightened back down on the female bottom end.*
