Procedure
A. Preparation for installation.
1) Disconnect the power cord from power outlet. Remove the water tank, portafilter, and drip
tray.
2) Remove the top cover after removing the screws indicated by the red arrows in Figure 13.
Pull out the top panel.
Figure 13. Top panel. Red arrows indicate the screws that hold the top panel.
B. Install SSR.
1) Remove the back panel of the machine after removing the two screws indicated in Figure 14a.
Loosen the screw indicated in Figure 14b by several turns (do not remove it). The back panel
can be removed by sliding it back and lifting up.

3) Mounting the SSR on the first hole from left. Apply small amount of thermal conductive
grease to the bottom of the SSR. Place it on the metal. The screw and washer should be
installed from the bottom of the base as shown in Figure 16a and 16b.

C. Connecting SSR Cables and Grounding Wire.
1) Connecting the cables to SSR as shown in Figure 17. The left side is for steam temperature
control. The two black cables are connected to the output. The blue cable is connected to the
negative of the input. Red cable is connected to the positive of the input. The right side is for
the brew temperature control. The two red thick cables are connected to the output. The
white cable is connected to the negative of the input. Red cable is connected to the positive
of the input.

2) There are two thermostats on top of the boiler as shown in Figure 18. The blue arrow points
to the brew control thermostat (it has a red dot on the top). The two cables on it have been
removed. One is the gray cable on top and other is the red cable below. These cables are
going to be connected to the red cables from the SSR output. The green arrow points to the
steam control thermostat. The cables on it need to be removed and connected to the black
cables from the SSR output.

3) As shown in Figure 19, the blue arrows show the red cables from SSR output are connected
to the cables originally were on the brew control thermostat. The green arrows show the
