Pulling Shots

This will outline different methods to pull shots once the Slayer Mod has been performed.

Classic Slayer Shot

This mimics the typical shot that would be pulled on an actual Slayer

Setup

• Set needle valve to barely open
• Place cup on scale under grouphead
• Hold single cup button to run pump
• Let pump run for 10 seconds
• Divide weight of water by 10 to get your flowrate in ml/s
• Adjust valve and rerun test until you get 1.4ml/s
• Make a mark on the machine so save this position
• Set preinfusion time to 0 seconds

The Pull

• Install portafilter
• Set valve to 1.4ml/s mark
• Press manual button to start shot
• Preinfuse for desired time
• Aim to start pressure ramp around 18s
• First drops should start around 20s
• Pressure should get to 9 bar at about 25s
• Open valve for desired amount of full flow time
• Aim for 2/3 of your total output weight
• Set valve back to 1.4ml/s mark
• Press manual button to stop the shot when target weight is reached (or a bit before)
