cylinder
WARNING!
The cylinder ( containing 1kg of CO
2
) should be installed in a well ventilated area of area
no less than 38m
3
.
If more than 1 gas cylinder containing 1kg of CO
2
is present within the same location, the
recommended ventilation area should be in proportion to the number of gas cylinders stored in that
location. A ventilated area in a non-enclosed area which could include the kitchen, living room etc.
See gas cylinder and MSDS sheet for complete list of warnings.
4.1
Secure the cylinder
Secure the gas cylinder supplied to a suitable wall, within 1 metre of the Command-Centre
TM
, in an upright
position. This is undertaken by screwing the metal bar holding the Velcro strap to a cupboard wall, 200mm
above the floor or base of the cupboard. Make sure the gas cylinder can stand in place before securing to the
wall. Due to regulatory requirements the gas cylinder must be stored securely and in an upright position.
4.2 Connect the regulator
Remove the gas cylinder from the strap. Make sure the regulator knob is turned fully anti-clockwise to the
end-stop before fitting. Screw on the regulator (clockwise). Be aware that some CO
2
may be discharged
from the connection to the regulator as the cylinder and the regulator are be assembled together. Any CO
2
released will be cold. Screw on the regulator to stop this leakage.
Note
The leaking CO
2
will be cold.
Note
Two plastic seals are supplied with a new regulator. Only one is required, the other is supplied as a
spare part.
4.3 Connect the gas hose
Connect the threaded end of the braided gas hose to the regulator, then connect to the John Guest fitting on
the top of the Command-Centre
TM
via the connection marked ‘CO
2
IN’
To turn the gas on, rotate the black knob on top of the cylinder clockwise. Then adjust the outlet pressure, by
rotating the regulator knob clockwise to between 2.7- 3.0 bar (green zone).
Note
The arrow should sit in the green zone of the regulator gauge; it should not fall in the red or yellow
zones.
4.4 Test for gas leaks
Using soapy water 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.
Refit the gas cylinder to the velcro strap. Ensure the cylinder is in an upright position.
Note
Care must be taken when working with high pressure CO
2
, and in no cases should the normal
operating pressure of between 2.7- 3.0 bar be exceeded.
