Safety
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 58 psi (4 bar) be exceeded.
Introduction
This unit has been designed to work in an enclosed, under counter installation without the need for an
additional ventilation kit, as cooling of the fridge system is provided by water from the mains supply
rather than air cooling.

Introduction and Specification

Installation and Commissioning
The chilled unit is designed to operate with the Billi™ range of tap/dispensing equipment and should
not be operated in isolation from these units.
•Locate the machine in a suitable enclosure, Quadra Sparkling is designed to work without the
need for additional ventilation, this is achieved by using water to cool the refrigeration system
rather than air.
Note: At this stage do not connect the unit to the electrical supply.
CO2 Gas and Water Connections
Drinking water and gas connections are via 6mm John Guest Speedfit fittings, which are black in
colour.
Condenser water connections are via ¼” John Guest Speedfit fittings, which are grey in colour. NOTE:
6mm tubing must not be used with ¼” fittings as this may lead to water leaks.
•Connect “WATER IN” to the water supply from the parent boiler. After all connections are made
the boiler unit should be on and ready to supply water to the cold unit. Water pressure in the
chiller is internally regulated at 19 PSI (1.3 BAR).
•Connect the “CO2 GAS IN” to the regulator, ensuring the pressure is set to 40 PSI (2.7 bar), and
turn on the supply.
•Connect “TO TAP” to the water dispense tap.
•Connect “CONDENSER WATER IN” to mains water and open the supply of water.
NOTE: This water supply to the “CONDENSER WATER IN” port must have a minimum
pressure of 1.3Bar.
•Connect “CONDENSER WATER OUT” to drain.
•Connect the flying lead from the parent boiler to the socket labelled “TO BOILER”.
•With the boiler ready to supply water plug in and turn on the chiller unit.
•The compressor will start, and the water pump will operate for approximately 20-30 seconds to
fill the carbonator vessel. Verify that water is flowing from the “CONDENSER WATER OUT” to
drain. The flow rate has been factory set to 5ml/s at 1.3 bar, so a low flow rate is expected to
drain, however, this expected to be a constant flow and should not be dripping.
•Once the water pump has switched off dispense still water until all air is expelled from the tap
and a smooth flow of water is established.
•Now dispense at least 1 ltr of soda water to help purge the system of any remaining air.
•After approximately 10 minutes, the compressor will stop as the chiller has reached its normal
operating temperature.

Installation and Commissioning
Note: The time taken for the chiller to reach operating temperature will vary depending on ambient
temperature, humidity and the temperature of the incoming water supply.
The Soda flow rate is factory set to dispense at 30 ml per second at a gas pressure of 40psi (2.7
bar). However, if an alternative flow rate is required follow the steps below:
1. Locate the flow adjuster screw on the side of the unit (Fig 1.).
2. To increase the flow rate turn the screw anti-clockwise.
3. To reduce flow rate turn the screw clockwise.
4. Adjustments can be made with either a large flat head screw driver or with a 6mm Alan key.
5. It is recommended to make incremental changes of no more than a quarter turn at a time until
desired flow rate is achieved.

water flow is available through the heat exchanger. If
overheating persists return for repair.
If no overheat is found check voltage to compressor
(230V AC).
If voltage not present check the temperature probes
and replace if required.
If voltage not present check control board fuses. If
necessary replace control board.
Control board not
operating. Check control board and main plug fuses. If
necessary replace control board.
Fridge failure If compressor is running & sufficient water is
flowing through the heat exchanger and there is
no cooling, return for repair.
Fridge Condenser Care & Maintenance
After a period of operation it is possible that, especially in hard water areas, scale deposits may
build up inside the fridge heat exchanger. To help reduce this it is recommended that the water
supply to the “CONDENSER WATER IN” is fitted with a chemical or magnet water conditioning unit.
These units work to reduce the possibility of calcium particles be deposited in the heat exchanger.
If the water supply does not contain a conditioning system calcium build-up may reduce water flow
and potentially lead to a blockage. To prevent this, periodic cleaning of the heat exchanger may
be required using a descaling solution. The frequency of this will be dependent on the hardness
of the water and the demand on the chiller.

1. Install Dispenser Assembly
Determine position of dispenser mounting
hole in sink top or bench top. Dispenser base
template (Diagram 5) may be cut out and
used to assist in correct positioning. Refer to
Diagram 2 for clearances allowed. Hole size
required is ø32mm.
The Billi XL dispenser is supplied with base
assembly preassembled into dispenser
upper and this must be first removed prior to
starting installation. Using allen key supplied
in installation kit, remove chrome plated
M4 screw from rear of housing. Twist base
casting around 60º and then slide assembly
out of upper housing. Carefully pull tubing
and electrical cable and plug through base
assembly.
—Stainless Steel Sinktop
A suitable 32mm hole punch (Part no:
857901) is available as an accessory from
Billi Pty Ltd. If possible, cut hole with die
mounted below the sinktop surface so that
burr is pulled downwards. Alternatively,
remove burr and radius edge of hole with
fine file. This allows barbed dispenser mount
to slide smoothly into mounting hole.
—Timber/Laminate Benchtop
Maximum benchtop thickness is 50mm.
Cut 32mm hole in appropriate position.
When drilling through a particle board
bench top, take care to avoid substrate
chipping and breaking away as drill breaks
through underside surface. We recommend
drilling a small pilot hole through benchtop,
partially drilling the 32mm hole from
underneath and then completing drilling the
hole from above. The large 30mm washer
supplied may be used to secure barb where
bench top substrate has chipped away.
—Granite/Marble Benchtop
For granite or marble bench tops
we recommend that you use a certified
stone mason to pre-drill the hole.
2. Activate Dispenser Swivel Feature
The XL dispenser can be installed either as
locked into straight position or able to swivel
45º in either direction. To activate the swivel
feature of your dispenser, remove the locking
piece from the dispenser base. Simply push
out the piece as show in Diagram 6. This will
allow the tap to swivel to the left and right.
3. Fit Dispenser Base
a. Cut a 32mm hole in sinktop or benchtop.
Remove burr if protruding upwards.
b. Push barbed mounting shaft through
mount hole.
c. Insert barb locking bush as shown in
Diagram 7. Finger tighten nut.
d. Ensure barb is centred in mount hole
before tightening. Check position of base
ring and gasket.
e. Moderately tighten locking nut using
multigrips or spanner. Take care to avoid
overtightening nut which may break the
plastic threaded shaft.
f. Place large D washer over thread as
shown in Diagram 7.
g. Cut off excess threaded shaft with a
hacksaw, using washer as a cutting guide.
(Diagram 8)
IMPORTANT: Remove burrs and check internal
bore is completely smooth.
4. Fit Dispenser Head Assembly
a. Feed dispenser tubing and loom through
center hole in the following order:
i. Dispenser power cord
ii. Silicone tubes
iii. Blue PE tube.
b. Gently pull hoses from under the bench
top. Do not attempt to force tubing through
with a pointed object as silicone tube is
easily punctured. Check tubing is not
kinked or twisted. Refer to Diagram 9.
c. Turn dispenser head assembly to
approximately 60° from the straight ahead
position of dispenser base. Slide head
assembly onto base assembly whilst
gently pulling tubing downwards from
underneath to prevent tubing bunching and
kinking. Head retaining lugs will pass nut
and slide down the 3 grooves on the swivel
bearing.
d. Once fully down, turn dispenser to
straight ahead position. Fit chrome
plated M4 retaining screw to lower rear
threaded hole and tighten using the allen
key supplied. If swivel feature is activated,
check dispenser now swivels smoothly 45°
