⚠️SAFETY INSTRUCTIONS

follow the steps as instructed below

Three rubber First Crack card holders
Cable
Instructions
Follow this numbered guide below step by step.
Remove the top plate. You can read how to do it here.
Remove the blanking bolt by using the 3-millimeter hexagonal key.
Removing the blanking bolt is essential so the First Crack card works. If the bolt is not present, continue to step 3.
3. Install the three rubber First Crack holders. Tighten them with the 6-millimeter spanner. NOTE: if already present, continue to step 4.
4. Plug the cable into the back of the First Crack card.
5. Install the First Crack card with the cable attached. The card has been designed so it can only be installed one way.
Locate it through the rubber holders.
Hold the card and pull the rubber until the card “snaps” onto the rubber holders.
6. Check the distance of the installed First Crack.
The First Crack card should NOT touch the back plate of the roaster.
7. Install the cable into the PCB – the red strip of the cable coming out from the First Crack card should face the right-side panel (as you look at the roaster from the front). That same red line should face the back of the roaster when connected to the PCB.
Push the connector to attach the cable to the PCB
This is how it should look after installation
9. Turn on the roaster.
10. Turn on First Crack detection, by following these four quick steps here.
Now you can set the BT threshold and Trigger count parameters to your liking.
