Put on the cover of the device.
Check that the lid is perfectly installed and that the appliance is
tightly closed. Improper installation of the drum inside the beer dispenser
will not allow a tight seal, which would affect the performance of the
appliance.
D. Draft beer
Check that the drum is at the correct temperature before use. If this is not
the case, a total absence of foam or a large amount of foam could be
observed.
When you serve the first glass of a new barrel of beer, this glass will be
composed mainly of foam. This is a normal phenomenon that occurs with
all types of draft beers.
Preparation of service glasses
Start by wetting the inside of the glasses in which you will serve the beer
with cold water. Without this trick, the beer will not foam.
