Step 3 – Connect Carbon Dioxide (CO

) Cylinder
(HCS sparkling models)
WARNING! Take care when working with high pressure carbon
dioxide. The gas cylinder must be installed in an open plan area,
or in an enclosed room with a volume no less than 50m
3
per 2.64kg
cylinder.
If more than 1 gas cylinder containing CO2 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

Secure the cylinder bracket
The gas cylinder must be secured vertically, held in place by a hook
and loop strap fixed to a bracket. Mark out the bracket location on
a suitable wall within 1 metre of the chiller. Ensure the gas cylinder,
regulator and bracket assembly can comfortably fit with sufficient
clearances before securing the bracket.
Connect the pressure regulator
The pressure regulator is supplied with interchangeable colour-coded
pressure relief valves. The GREY-coloured, 100 psi pressure relief
valve must be used for this application. If it is not fitted, unscrew the
installed pressure relief valve and screw in the GREY-coloured valve.
Attach the pressure regulator to the gas cylinder. Ensure all surfaces
are clean and the plastic seal is fitted securely inside the large chrome
nut. Do not force the seal to fit. A second plastic seal is provided as a
spare.
Turn the regulator OFF by rotating the regulator knob all the way out,
in an anti-clockwise direction.
Connect gas hose, non-return valve and stop valve
Use 2 hose clamps to secure the black hose to the barbed regulator
outlet, taking care not to lose the small sealing ring (olive).
Install the non-return valve (supplied) in the black hose, close to
the cylinder (approximately 300mm), checking the direction of flow
matches the arrow on the valve.
