Once the unit is connected to the mains
water and electricity, and the ice-bank
tank has been filled, you can install the
E290 food-grade carbon dioxide (CO
2
)
cylinder.
The machine is not equipped with a
CO
2
pressure reducer or CO
2
cylinder
(optional).
Inside the machine, you can install
cylinders with a maximum diameter of
160 mm and a maximum height of 780
mm – standard 5 kg or 6 kg cylinders are
generally within these dimensions. The
unit is equipped with a tear tape for the
safety fixing of the cylinder.
To increase or decrease the level of
carbonation of the water, you need to
adjust the screw (1). Turning it clockwise
increases the level of carbonation. We
recommend that you do not exceed 4
bar of pressure (2).
To reduce the carbonation level, turn
the screw anti-clockwise. The level will
decrease as soon as sparkling water is
dispensed.
To achieve a good level of carbonation,
you need to wait until the water is
sufficiently cold – i.e. at least one hour
after installation.
