Once the unit is connected to the mains
water and electricity, you can install the
E290 food-grade carbon dioxide (CO
2
)
cylinder.
On request, a CO
2
pressure reducer
with its cylinder to assemble outside the
machine can be supplied.
Insert the CO
2
inlet tube from the
cylinder into the joint (1). To be sure
to remove any air in the hydraulic
circuit and to achieve a good level of
carbonation, before opening the faucet
on the CO
2
cylinder pull the ring of the
remote safety valve (2) until water comes
out of it.
When the cylinder is open, to increase
or decrease the level of carbonation of
the water, you need to adjust the screw
(3) on the pressure reducer. Turning
it clockwise increases the level of
carbonation. We recommend that you
do not exceed 4 bar of pressure (4).
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.
