Changing the CO2 cylinder
CO2 Regulator
Note When removing hose, take care not to
lose plastic olive from the fitting.
• Turn the CO2 cylinder regulator off, turn clockwise to the end stop.
• Remove the cylinder from the cupboard and disconnect the regulator. If
the braided hose is removed from the regulator, be careful not to lose the
small plastic sealing olive, located inside the end of the hose.
• Screw the regulator and hose assembly clockwise onto the new cylinder.
Be aware that some CO2 may be discharged from the cylinder joint. Any
CO2 released will be cold.
• Install the cylinder in an upright position (use the hook and loop securing
strap).
• Turn the regulator on (turn regulator knob anti-clockwise to end stop).
• Check all joints for gas leaks using a sponge and soapy water.
• Purge the gas lines, see CO2 purge , page 11.
Leak Test
Stage 1
• Turn the gas off.
• Using soapy water applied with a
sponge, or with a brush, cover all of
the gas joints with a liberal amount
of suds.
Stage 2
• Turn the gas on.
• Inspect the joint for leaks.
• If any bubbles appear, the joint will need
to be resealed and tested again.
After replacing a cylinder or after making a gas connection,
perform a leak test
to check for gas leaks between regulator and cylinder, and
between regulator and braided hose.
