Cylinder
3.1
Secure the cylinder mounting
Secure the gas bottle supplied to a suitable wall, within 1 metre of the unit, in an upright position. This is done
by screwing the metal plate holding the Velcro strap to a cupboard wall, 200mm above the floor or base of
the cupboard. Make sure the gas bottle can stand before securing to the wall. Due to regulatory requirements
the gas bottle must be stored securely and in an upright position.
3.2
Connect the regulator:
Make sure the regulator knob is turned fully anti-clockwise to the end-stop before fitting. Fit the regulator to
the gas bottle. Be aware that some CO
2
may be discharged from the connection during assembly. To avoid
excess gas leakage, promptly screw the regulator on to the bottle.
3.3
Connect the gas hose:
Connect the braided gas hose to the top of the undersink unit via the John Guest fitting marked ‘Gas IN’
Then connect the threaded end to the regulator, taking care not to lose the plastic olive located inside the
threaded nut. To turn the gas ON, rotate the regulator knob clockwise and adjust to 2.7-3.0 bar (270-300kPa).
The arrow should sit in the green section of the regulator gauge; it should not fall in the red or yellow
sections.
3.4
Test for gas leaks:
Using soapy water perform a leak test. Apply the soapy water to the gas connections using a sponge. 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 regulator is turned off when tightening or refitting the leaking
connection.
Refit the gas bottle to the Velcro strap and secure the bottle 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 2.7-3.0 bar (270-300kPa) be exceeded.
Connect the unit to the mains power supply.
WARNING:
This 1kg cylinder must be installed in an open plan area or in an enclosed room, with a volume no less than
20m
3
. 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 complete list of warnings.
