Install & Operation Manual
30/60-Litre - Refillable CO2 Bottle Installation
NOTE:
• Before connecting the CO2 bottle ensure
the gas being used is food certified.
• Do not lay the CO2 bottle on its side
whilst attaching the pressure reducer,
make sure it is always in an upright
position when carrying out this task.
•
Always ensure the reducer’s working
pressure is higher than the cylinders max
pressure.
• Do not place hands or any other part of
the body near the gas as this may cause
freeze burns.
• A small amount of gas leakage during
set-up/replacement is normal.
1. Connect the assembled CO2 bottle and
regulator to the CO2 inlet on the rear
panel (60L) using a 6mm pipe or side
panel (30L) using the 4mm pipe (see Fig1)
2.
In instances where a refillable CO2
bottle is being used screw the pressure
reducer on to the gas bottle with a
spanner (28mm). If however a single-
use gas bottle is in operation, screw the
reducer on to the bottle by hand.
3.
If using a refillable gas bottle open it
by turning the upper hand grip counter-
clockwise (item1- fig 2).
4. Ensure the CO2 bottle is securely
connected to the dispenser using the
4mm plastic tube.
5. Insert one end of the tube into the quick
fit coupling at the rear or side of the
machine, and the other connected to the
reducer of the gas bottle.
6. Open the gas bottle by turning the upper
hand grip counter-clockwise (item1- fig 2).
7. Turn the black handle of the pressure
reducer clockwise (turning towards the +
sign) (item 2- fig 2).
8. Check that any connection points are
free of leaks using soapy water.
Adjusting Sparkling Water
By adjusting the pressure reducer it is
possible to increase or decrease the amount
the amount of CO2 present in the water; the
optimal recommended values range from
2 – 5 bar. A higher pressure will increase the
amount of carbonation in the water, with a
lower pressure producing ‘slightly sparkling’
water. CO2 pressure must be set at
+0.5Bar > incoming water pressure.
Replacing a Refillable CO2 Tank
1. Detach the CO2 bottle from any
supporting chains or belts.
2. Close the valve at the top of the bottle
by turning it clockwise until completely
locked (item1- fig 2).
3. Close the pressure reducer by turning the
knob anticlockwise (item2- fig 2).
4. Remove the CO2 pipe from the pressure
reducer, and detach the other end from
the dispenser.
5. Screw the adapter (optional) for the
external CO2 bottle to the new pressure
reducer and tighten it firmly.
6. Connect one end of the new CO2 pipe
to the pressure reducer and the other to
the appropriate connection point on the
dispenser (see page 5 or 6).
7. Screw the ring nut of the adapter
assembled on the pressure reducer to the
CO2 bottle.
8. Open the valve at the top of the new
CO2 bottle.
9. Reattach any chains or belts removed
from the bottle and return it to its normal
position.
10. Check for leaks using soapy water.
