BOOKOO Espresso Monitor Pressure Sensor Product Manuals

01 Product Information and Instructions

02 Installation Tutorial

2.1 Prerequisites

• The EM has a G1/8 thread and comes with a G1/8 to M6 adapter as standard, so the EM is suitable for coffee machines with G1/8 and M6 threads at the pressure gauge, while other sizes of coffee machines may need to purchase other accessories to achieve compatibility, for more details, please visit the official website or the consulting service team.
• Others: It is recommended to seek professional guidance for any modification or retrofitting, ensuring proper sealing at the interface. The BOOKOO team is not responsible for any modification actions.

2.2 Installation Steps

• Use a wrench to remove the original pressure gauge, exposing the threaded port.
• Applicable devices screw this EM pressure sensor on directly, compatible devices screw the EM pressure sensor on after connecting the matching adapter.

2.3 Note

• When connecting to a group head operating over 100°C, it is necessary to reduce heat transfer by using an adapter to ensure the EM operates within the normal working temperature.
