6.3.1 Bottle Piston Supply
The 4 bar line supplies the Bottle Pistons to raise and hold the bottles upwards,
in order to ensure an air tight seal on the Tap. It is recommended to use a
compressed air supply in case of more than 12 bottles installations.
4.0 Bar pressure must be provided from either:
an air compressor
the Nitrogen (or Argon) Gas supply cylinder
a Nitrogen Generator (recommended for very large installations)
If an air compressor is used, the air source must be equipped with a sluice
gate, a pressure regulator (4 Bar outlet required) and a filter to avoid impurities
blocking the pneumatic circuits. A moisture trap is also required in humid
environments.
Connect the Bottle Piston Supply to the Enomatic model by firmly pushing the
4mm FOODGRADE LLDPE pipe into the friction fitting.
6.3.2 Nitrogen ( Argon) Gas Supply
Main purpose for the use of Nitrogen or Argon is to preserve
wines from oxidation processes. As soon as a bottle is engaged
into the machine, Nitrogen is inflated into it and the preservation
starts. Second main purpose for Nitrogen is to dispense wines
from the bottle to the Serving Spout. It is also used to clean the
Serving Spout after each serve.
Foodgrade Nitrogen (or Argon) Gas of greater than 99.5% purity
must be used. This is typically supplied as a compressed gas
stored in cylinders, at high pressure. The pressure varies
between countries but it is typically between 150 or 200 Bar.
Alternatively a certified nitrogen generator can be used.
The Nitrogen (or Argon) Gas cylinder must be secured in a
vertical position and stored in a ventilated space. It must be connected to a
regulator to reduce the pressure to 0.16 Bar (that value may vary depending
installation features).
The following procedure must be carried out when connecting the Nitrogen (or
Argon) Gas cylinder:
1.
Ensure the regulator outlet valves are in the
closed position (as shown in the photo).
2.
Insert the seal (if previewed) and tight the
regulator system to the cylinder and ensure an
air-tight connection.
3.
Open the cylinder valve, note down the
indicated max pressure value, and close the
cylinder; the value doesn t have to decrease
within 15 in order to avoid risk of leak.
4.
Connect the Nitrogen (or Argon) Gas Supply
from the regulator to the outlets on the Enomatic model by firmly pushing
the 4mm FOODGRADE LLDPE pipe into the friction fitting, on the Enomatic
model and on the regulator as well.
5.
Completely open the valve of the cylinder.
6.
Open the regulator levers.
7.
Note down the indicated max pressure value, and close the cylinder; the
value doesn t have to decrease within 15 in order to avoid risk of leak.
