Installation Instructions

CO
2
Gas Connection:
Secure the gas bottle to a suitable wall, within 1 metre of the unit in an upright
position. This is done by screwing the metal bar holding the Velcro strap to the
wall. Locate the strap 200mm from 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.
Remove the gas bottle from the strap. Make sure the regulator knob is turned
fully anti-clockwise to the end-stop before fitting. Screw the regulator to the
gas bottle. Be aware that some CO
2
may be discharged from the connection to
the regulator as the bottle and the regulator are assembled together.
Any CO
2
released will be cold.
Connect the braided gas hose to the regulator, taking care not to lose the
plastic olive in the braided hose nut. Turn on the regulator clockwise and adjust
to 0.27 MPa (2.7 bar). The arrow should sit in the green section of the regulator
gauge; it should not fall in the red or yellow sections.
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.
Once satisfied that there are no leaks and with the regulator set at 0.27 MPa
(2.7 bar), refit the gas bottle to the Velcro strap and secure the bottle.
NOTE:
Care must be taken when working with high pressure carbon dioxide,
and in no cases should the normal operating pressure of 0.27 MPa (2.7 bar) be
exceeded.
WARNING:
A gas cylinder containing 1kg of CO
2
should be installed in a well ventilated
area or an 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 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.
Step E - Testing and Commissioning:
Do not
turn power or water on to the unit. The carbonator must be purged first
with the CO
2
gas. Failure to do so will result in poor tasting water. With the
regulator set to 2.7 bar, turn the sparkling water lever on (white ringed lever)
The CO
2
will start to run out of the tap. Gas will purge or escape from the tap
at this point. Let it run for approximately 5 seconds to completely fill the tank.
Close the sparkling lever by rotating back to upright.
Turn on the still water lever (blue ringed lever) then turn on the water supply to
the unit. First air, then water will flow from the tap. Allow the water to continue
to flow for about 7.5 litres, which is required to activate the filter. Once this has
been done turn off the still water lever.
ROTATE
NOTE: When removing hose, take
care not to lose the plastic olive
from the nut.
