Section 3
CO
2
Cylinder
STORAGE WARNING:
CO
2
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 warning.
3.1
Secure the cylinder cradle
After removing all packing material, mark out the cradle location, and fit it on a suitable wall, within 1 yard
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 hose to the threaded end of the regulator (do not lose the small sealing olive). When
commissioning, first turn the gas ON by rotating the valve on top of the cylinder anti-clockwise. Then adjust
the outlet pressure, by rotating the 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 two 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.
