Assembling

Assembling the AGO Film Processor

Assembling starts after you have loaded your film onto reels in darkness and placed them into a Paterson tank. Follow the steps below to prepare the device before starting the development process.


Step 1 Attach the rear stand to the tank

Fit the rear stand onto the Paterson tank before attaching the AGO.

Step 2 Attach AGO to the tank

Place AGO onto the tank with the funnel holes facing down. Press the AGO firmly onto the tank using your upper body weight to ensure the rubber seal seats properly.

Alternatively, place the tank on the ground in a vertical position and attach the AGO from above, pressing down moderately with your bodyweight. Make sure the funnel holes are facing down towards the bottom of the AGO.

Step 3 Place on a flat surface

Place the AGO on a flat surface and you are ready to start developing.

Funnel holes must always face down when attaching AGO to the tank.
