IMPORTANT: HOW TO ADJUST THE EXPANSION VALVE.
For this, the first thing is to disconnect the silicone tube that carries the excess
water to the drain cup.
We will introduce the blind coffee filter (supplied with the equipment) into the
filter holder and assemble it in the group of the valve to be regulated.
Activate the group and adjust the pump up to 11 bars.
Then, using a flat‐blade screwdriver, we will insert it into the valve until it is
positioned and we will turn one way or the other until we see the appearance
of water drops constantly.
