Normally the default gigler is 0.8 mm and if want-
ing to increase the pre-infusion time the gigler
can be tightened to 0.5 mm.
In this case the water would pass more slowly
along the whole path and would soak the coffee
capsule more slowly, thus increasing the time of
pre-infusion.
The flowmeters can be removed in block:
QUICK REPLACEMENT OF THE ENTIRE BLOCK
We recommend changing the valve located
downstream of fan at least once a year.
Attention must be given to the gigler at the exit
from the fan: it can clog and affect the pre-
infusion.
To remove, clean or change it use an Allen
wrench or a 4 mm hex screwdriver.
1 Unscrew the three screws that hold the
assembly.
2 Unscrew the nut from the tube which feeds
the block with a 14 mm wrench while holding
the fitting with a 12 mm wrench.
