Fig 12. Critical parts location. Red arrow on the left indicates where the brown colored
power cable for controller is going to be tapped. The right red arrow indicates where
black colored power cable for the controller, the steam control cables, and pre-infusion
pump control cable are going to be installed. Green arrow indicates the location that
SSR is going to be mounted. Yellow arrow points to the steam control thermostat. Blue
arrow indicates the coffee thermostat location (it is below the cables, close to the bottom
of the boiler).
B. Install the SSR.
1) Assemble the cables on to the SSR as illustrated in Fig 13. The two red-colored thick
cables with soft silicone rubber insulation should be connected to the terminal marked as 1
and 2. It doesn't matter which one goes to 1 or 2. The red-colored thin cable should be
connected to 3 (+). The white-colored thin cable should be connected to 4 (-). The clear
plastic protection cover on the SSR can be removed for easier installation of the cable.
Tighten the screws, and make sure the cables hold securely.
