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.
Models 150lt/h are equipped with a CO
2
pressure reducer with two gauges. They
never come fitted with a CO
2
cylinder.
Inside, you can install cylinders with
a maximum diameter of 140 mm (up
to 205 mm on “10 kg” version) and a
maximum height of 850 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. Photo 26.1 shows a 4 kg
cylinder with a total height of 580 mm.
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.
