Section 3 - CO
2
Cylinder
STORAGE WARNING:
CO
2
gas cylinders must be installed in an open plan area or in an enclosed room, with a volume no less than
50 cubic metres (65 cubic yards) for each 2.6kg (6lb) of stored gas. If more than 1 gas cylinder containing
CO
2
is present within the same location, the recommended ventilated area should be in proportion to the
number of gas cylinders stored in that location. A ventilated area is a non-enclosed area which could include
the kitchen, living room etc. See gas bottle and MSDS sheet for a complete list of warnings.
3.1
Secure the cylinder cradle:
After marking out the cradle location, secure it to a suitable wall, within 3 feet of the Command Center. Make
sure the gas bottle, regulator and cradle assembly can comfortably fit, with sufficient clearances, before
securing the cradle inside the cabinet. Due to regulatory requirements the gas bottle must be stored securely
and in an upright position. Secure the bottle with the hook-and-loop straps provided.
3.2
Connect the regulator:
After removing all packing material, fit the regulator to the gas bottle as shown in the diagrams. Ensure the
plastic seal is fitted securely inside the large chrome nut, before attaching to the gas bottle. If the plastic seal
is not an easy fit over the spigot, soak it in hot water, before re-applying. Do not force the seal to fit.
Turn the regulator OFF by rotating the regulator knob, all the way out, in an anti-clockwise direction.
NOTE:
Two plastic seals are supplied with a new regulator. Only one is required, the other is supplied as
a spare part.
3.3
Connect the gas hose:
Connect the braided gas hose to the top of the Command Center via the John Guest fitting marked ‘Gas IN’
Then connect the threaded end to the regulator (Do not lose the small sealing olive). When commissioning,
first, turn the regulator, grey knob, all the way out (anticlockwise). Then turn the gas ON by rotating the black
knob on top of the cylinder, anti-clockwise. Finally, adjust the outlet pressure by rotating the grey regulator
knob in a clockwise direction, to 3.0±0.1 bar (39±1 psi) (green zone)
NOTE:
The arrow should sit in the green zone of the regulator gauge; it should not fall in the red or yellow
sections.
3.4
Test for gas leaks:
When commissioning, use soapy water to perform a leak test. Apply the soapy water to the gas connections
using a sponge or brush. If any bubbles appear and grow, there is a gas leak at the connection. Clean away
the soapy residue and tighten or refit the leaking connection. Make sure the gas is turned off when tightening
or refitting the leaking connection.
Fit the gas bottle into the cradle and secure with the Hook-and-loop strap. Ensure the bottle is in an upright
position.
NOTE:
Care must be taken when working with high pressure carbon dioxide, and in no cases should the
normal operating pressure of 3.0±0.1 bar (39±1 psi) be exceeded.
