Introduction
The S18 UC is a high capacity cooler carbonator. The unit is designed
to deliver a choice of filtered chilled and ambient still water and chilled
carbonated water.
The unit should be isolated from the electricity supply before removal of any
covers. Great care must be employed when working with high pressure
carbon dioxide, and in no cases should the maximum operating pressure of
4bar be exceeded. The over counter unit uses R290 (Care 40, Propane)
refrigerant. Below are some safety warnings which the end user must adopt
to mitigate the risk of unsafe conditions arising.

Installation and Commissioning
Page 4 of 16
• The unit must be installed by a competent person, on a firm level
surface capable of supporting the weight of the machine, when the
bath is filled.
• Make all connections for water (inlet and outlet), gas and electricity,
but do not turn these on at this stage.
o If the recirculation system for this unit is not being utilised the
Outlet and Return can be linked by a length of insulated John
Guest tubing.
• Important: Ventilation openings in the machine must not be blocked
and free movement of air through the unit must be possible.
Inadequate ventilation will shorten the life of the fridge system. Air is
drawn in through the front, sides and bottom of the unit and
exhausted to the rear.
• Ensure that the supplied base guard is fitted to the underside of the
unit.
• Fill the bath with water. To do this remove the lid from the unit and
remove the bath inspection cover. Min and Max water levels are
marked on the front of the unit.
o If the recirculation system is being utilized, then the bath water
will need to be monitored and topped up accordingly as the
recirculation tubing fills up. This will occur during first power on.
• Remove the cover from the filter housing and fit all water filters into
the housing. The filters are a twist and lock design and will lock into
place after a ¼ turn (a clicking sound will be heard, and the red
release tab will spring into its locked position.
• Turn on the CO2 gas supply, ensuring the pressure is set to 55 psi
(3.8 Bar).
• Purge the carbonator can by pulling the ring pull of the pressure
relief valve on top of the can and let gas flow for up to 5 seconds
then close.

• Before turning on the water supply locate the flush valve at the front
of the filter housing and turn the lever to the ‘Flush Position’. Connect
the clear PVC tubing supplied to the flush outlet and place the other
end of the tubing into an empty bucket or to a drain.
• Turn on the water supply. Water will now begin to flow through the
water filters and the flowmeter will display a flow rate. When the
filters are full, water will flow out of the clear tubing. Initially the water
will contain some sediment from the carbon filtration, this is normal,
allow to flow until clear.
• Once clear, turn the flush valve lever back through 180° into the ‘Unit
Supply Position’. Water will now be directed into the water circuit of
the unit.
• Open the still tap until water flows (this may take a few seconds as
the cooling coil inside the unit fills with water) then close. At this
stage re-fit the lid and filter housing cover.
• Turn on the electrical supply. After a short delay the fridge system
will activate (check for air exhausting to the rear of the machine) and
the carbonator can fill pump will activate; once the can is filled the
pump will automatically switch off.
• To ensure all air is purged from the carbonator can, turn off the
electrical supply and dispense sparkling water until the can is
empty, then allow gas to flow from the dispense tap for 5 secs.
• Restore the electrical supply. The fridge system and can fill pump will
activate as before and the can pump will switch off when the can is
full. When the compressor and fans switch off the unit is ready.
• Depending on the ambient temperature and the temperature of the
incoming water the time required for the fridge system to switch off
can take 3 to 5 hours. In very high ambient conditions (90°F/32°C or
higher) the time required may be over 5 hours.
• Note: If the bath has been filled to the point of overflow,
approximately 17 fl oz (0.5 liters) of water will be displaced as ice
forms in the bath.
