HOW TO CHECK THE OPERATION OF THE
INJECTOR?
Should it occur that one unit dispenses less
water than the others check to see whether
the problem is related to the injector that has
accumulated too much limestone. The following
instructions are indicative because the result will
depend on the incoming water pressure.
1 Turn off the water using the tap on the pump.
2 Unscrew the Teflon tube placed on top of
the coffee boiler of the unit that delivers less
water, using a 12 mm wrench.
NOTE
In the more recently manufactured machines
have tubes in copper with conical fittings. To
remove the boiler use a 13 mm wrench.
