Installing the Dispenser
IMPORTANT: This Billi appliance is to be installed by a licensed trades person in accordance
with AS/NZS 3500.1 and AS/NZ 3500.2 and in compliance with applicable state regulatory
requirements. For correct operation of this appliance, it is essential to observe the
manufacturer’s instructions.
1. Benchtop Preparation
Two 10mm holes, and one 50mm
hole will need to be drilled into the
benchtop as shown in the template
shown in Diagram 5.
When drilling into timber/laminate it is
recommended to drill a small pilot
hole first. Then partially drill from
underneath before completely drilling
from above. This will help to prevent
chipping the benchtop.
For granite or marble benchtops we
recommend you use a certified stone
mason to pre-drill the holes.
Important: Remove all burrs
around the holes and check
internal bores are completely
smooth.
2. Cords and Tubing
Pull power cord through the 50mm
hole first. Then pull the remaining
silicone tubing and dispenser power
cord through the 50mm hole.
3. Securing
Align the bolts with the two 10mm
holes and lower the dispenser into
position.
Ensure the gasket is correctly
aligned, then tighten the nuts on the
underside of the benchtop to secure
the dispenser.

Installing the Underbench Module –Quadra
1. Flush Water Supply
Flush water supply pipework before installing the
underbench unit by connecting 600mm flexible braided
hose to the supply tap and running water into a bucket.
Blockages/unit malfunction caused by debris are not
covered under warranty.
2. Install Underbench Unit
Take care to observe minimum clearances.
Ensure there is adequate access to service the unit,
taking into account the tube lengths and space
available Refer Diagram 4, page 6.
3. Connect Dispenser Tubing and Electrical Plug
Connect all tubing and electrical plugs as shown in
Diagrams 9, 10 &11.
Ensure correct orientation of dispenser power plug
before insertion. Trim tubes to correct lengths using
plastic tube cutter. Do not leave excess tubing which
will sag, trapping water. Fit spring clamps supplied to
retain silicone rubber tubing to barbed fittings.
IMPORTANT: Boiling outlet (red), vent tube (grey)
must not be kinked and must be installed with a
continual fall and no sag.
4. Connect Dispenser Drain Kit
a. Drill ½ inch hole (using drill bit not provided)
into drainage point (pipe).
b. Clip white john guest fitting into sliver hose
clamp.
c. Fit hose clamp to drainage pipe, ensuring the
while john guest fitting surrounds the hole
drilled.
d. Take the drain hose connection provided and
connect the 3/8 hose into the drain clamp.
e. Connect the 3/16 hose into the condenser
outlet on the unit and tighten the nut. (Nut to
be finger tightened only).

Turn On the Water Supply
Turn on the water supply tap and ensure that
there are no leaks. Remove front panel of unit
and remove packing foam from under filter
canister. Ensure filter canister is securely
locked back into place. Replace front panel.
Turn On Electricity
Turn on power switch. Check normal time
display is showing. Status line should display
‘INITIAL FILL’. Boiling and chilled water tanks
are now filling. Dispenser icons flash orange
slowly.
Cold Water
During the initial fill, cold water valve
automatically opens to fill the cold tank. After
approximately 1 minute, cold water will begin to
flow from the dispenser outlet. Water will
continue to run for a further minute to flush and
condition the filters.
IMPORTANT: Container should be placed
under the dispenser outlet to collect any
water being dispensed during the filter
flush.
Hot Water (Auto Boiling Calibration)
Auto Boiling Point Calibration: The hot tank will
first fill to the height of the low level sensor. The
water is then heated until it reaches boiling
point. The unit will continue to boil for up to 30
seconds while the temperature sensor
calibrates.
WARNING: Steam and small amountsof hot
water may be discharged from the outlet
and vent during this period. While
calibration is underway the hot water
indicator will flash yellow. The hot water set
point is calibrated 1.5°C below the boiling
point. Once calibrated, the unit will resume
normal operation and the calibration data
will be saved. The unit will not re-calibrate
under normal circumstances.
Setting the Programs
The Quadra operational settings have been
factory set for a typical installation. Clock is set
to Eastern Standard Time (EST). Refer to
Quadra User Guide for setting instructions. In
some installations, boiling water delivery
settings may need to be changed as outlined
below.
Tube length setting
The Quadra’s boiling water flow rate slows
briefly as water first enters the cup to prevent
splashing. Correct timing of the moment of
reduced flow is dependent on the length of the
tube between the Quadra module and the
dispenser. The standard timing is set for a tube
length of 500mm but this setting can be simply
altered to suit the installation. After installation,
measure the length of the red tube from the
underside of the dispenser to the boiling water
outlet fitting. If the measured length is less than
450mm or greater than 550mm, the correct
value should be set in as follows:
1. Press SELECT. Display changes to
menu selection mode.
2. Press DOWN 4 times. Shaded curser
shows ‘INITIAL SETUP’.
3. Press SELECT. Display shows:

Calibrating boiling water temperature
(Manually)
The boiling water temperature has been factory
calibrated. Because water boils at a slightly
lower temperature at elevated altitudes, the
factory-set temperature may be too high for
units installed at certain inland locations. If the
local altitude is greater than 500 metres above
sea level, a calibration cycle should be
performed.
The procedure is as follows:
1. Use the selection procedure as described
above, in Steps 1, 2 and 3.
2. Press SELECT twice to select ‘Calibrate
Boiling Water’.
3. Press SELECT twice to begin cycle.
4. The unit will fill and heat (if not yet up to
operating temperature before cycle
begins).
CAUTION: Steam will discharge from the
vent outlet. Once correct boiling
temperature is established, the Quadra
recalibrates its internal settings and the
display panel returns to normal.
