Cylinder
STORAGE WARNING:
This cylinder must be installed in an open plan area or in an enclosed room, with a volume no less than 40m

.
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. (See: www.zipindustries.com)
5.1
Secure the cylinder cradle
After removing all packing material, mark out the cradle location, and fit it on a suitable wall, within 1 metre
of the unit. Make sure the gas bottle, regulator and cradle assembly can comfortably fit, with sufficient
clearances, before securing the cradle inside the cupboard. Due to regulatory requirements the gas bottle
must be stored securely and in an upright position. Secure the bottle with the velcro straps provided.
5.2
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.
5.3
Connect the gas hose:
Connect the braided gas hose to the top of the underbench unit 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,
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 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
sections.
5.4
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 Velcro 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 between 2.7- 3.0 bar be exceeded.
