Adjustable
pressure gauge
Adjust to 4-6 bar.
Installation instructions
Test joints for
leaks
Connect CO
2
hose to chiller
Measure and trim the black hose to connect to the gas inlet at the
front of the chiller, marked “IN CO
2
”. Use straight and elbow fittings if
required for routing.
Install a stop valve in the black hose, in an accessible location,
(recommended 100 mm from the chiller inlet).
Adjust gas supply
• With the CO
2
cylinder closed, remove the air in the circuit by
operating the sparkling tap for a few seconds.
• Slowly open the CO
2
cylinder valve by turning the knob anti-
clockwise, until it is fully open.
• Adjust the regulator knob until the gauge shows between 400-
600 kPa (4-6 bar, or 58-87 psi), depending on the degree of
carbonation required.
Optimal carbonation
Ensure the inlet water pressure is below 300kPa (3 bar/45 psi)
To improve carbonation, set a lower temperature on the chiller
machine.
Test for gas leaks
IMPORTANT: After replacing a gas cylinder or after making a gas
connection, test for gas leaks.
Use soapy water to perform a leak test. Turn OFF the gas at the
cylinder and turn OFF the stop valve near the chiller. Apply a liberal
amount of soapy water suds to the gas connections using a sponge or
brush.
Slowly turn ON the gas at the cylinder. Inspect for leaks between
the regulator and cylinder, and between the regulator and hose.. If
bubbles appear and grow, there is a gas leak at the connection. Clean
away the soapy residue and ensure the gas is turned off, then tighten/
refit the leaking connections.
Allow approximately 1 hour after installation for the water to reach
optimum chilled temperature and carbonation level.
