Determine Unit Location
Plan the installation. Dispenser tube lengths,
position of power and water outlets, required
air space around the underbench module and
access for service must be considered before
cutting tube lengths. Refer to Diagrams 1,2
and 3 for clearances around the dispenser
and unit. Unit must be installed horizontally
with plastic vent panel facing to front of
cupboard. The B-5000 is designed for internal
installation only.
Water Supply
The B-5000 must only be connected to a cold
water supply. A ½” BSP stop tap (not supplied)
is to be installed in an easily accessible
position within 600mm from the B-5000
water supply inlet. The B-5000 incorporates
a certified pressure limiting and backflow
prevention device. Do not fit an additional
pressure limiting valve.
Dynamic inlet supply pressure:
Min. 250 kPa, max. 1000 kPa
Supply Temperature: min. 5°C max. 30°C.
Do not install with water that is
microbiologically unsafe or with water
of unknown quality without adequate
disinfection before or after the system.
Systems certified for cyst reduction may
be used on disinfected water that may
contain filterable cysts.
Ventilation
The B-5000 requires some cupboard
ventilation and adequate air space as well
as an unobstructed clearance of at least
100mm on each side of the underbench unit
is necessary.
IMPORTANT: Insufficient ventilation will cause
inefficient refrigeration system operation,
increasing power usage.
Power Requirements
A single 10 amp standard power
outlet is required. All B-5000 units supplied
with 1 metre flex cord and plug.

1. Install Dispenser Assembly
Determine position of dispenser mounting
hole in sinktop or benchtop.
Dispenser base
template (Diagram 4) may be cut out and
used to assist in correct positioning. Refer to
Diagram 2 for clearances allowed. Hole size
required is ø32mm.
Stainless Steel Sinktop
A suitable 35mm hole punch (Part no:
857901) is available as an accessory from Billi
Australia 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 a large chip
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 underside particle
board bench top has chipped away.
* For stone or granite bench tops you
will require a certified stone mason
to pre-drill the hole.
2. Activate Dispenser Swivel Feature
To activate the swivel feature of your
dispenser, you will need to remove the
locking piece from the dispenser base.
Simply push out the piece as show in
Diagram 5. This will allow the tap to
move 45 degrees 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 6. 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 7)
IMPORTANT: Remove burrs and check internal
bore is completely smooth.
4. Fit Dispenser Head Assembly
a. Feed dispenser tubing and loom through
centre hole in the following order:
i. Dispenser power cord.
ii. Silicone tubes.
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.
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. Mounting 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 activated
check dispenser now swivels smoothly
45° in each direction.

45mm – see diagram 13.
Drill a pilot hole using bracket as a
template. The template could also be
used as a guide to cut into the plaster.
Install Mount Bracket
Fasten the mount bracket on to the
wall using phillips head screwdriver
(ensure the spring clips are facing up)
– see diagram 14.
Plaster and Paint
Start plastering as required.
Wait for the plaster to dry before cleaning
the bracket.
Use a light sandpaper to give smooth
finish on the drywall.
Then paint as required.
Completing Installation

Magnetic remover tool may be
required again. Do not throw away.
Determine Remote Panel Location
Dimensions and layout are shown in
diagram 9. Panel can be installed on a
wall, benchtop or even inside a cupboard
Minimum cut out dimensions are 121mm
height x 70mm width. Minimum depth
must be 20mm.
Cut out cavity into the plaster wall.
Ensure the cable is pre-installed into the
flush mount bracket before plastering.
Place the flush bracket into the plaster
wall with the cable gap facing towards the
ground.
Installing the Remote Panel
Cable must be protruding out of the
bottom of bracket – see diagram 9.
Tape up the cable terminals before
plastering process – see diagram 10.

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 1, page 2.
3. Connect Dispenser Tubing
and Electrical Plug
Connect all tubing as shown in Diagram 17
& 18. 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.
1. Turn On the Water Supply
Turn on water supply 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.
2. Power On
When power is applied the system checks
the water level in the hot tank and if empty
(below the low level sensor) then the unit will
enter the boiling point calibration mode. This
will normally only occur the first time a new
system is turned on.
On power ON, if the hot tank level sensor is
above the low level sensor, the unit will enter
its normal operating mode at full power.
This will happen when the system has been
installed and used at least once.
IMPORTANT: On initial power up, leave the
unit for 10 minutes before attempting user
setup.

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: and small amounts of hot water may
be discharged from the taps and vent during this
period.
While calibration is underway the hot water
indicator (red) will double blink rapidly. The hot
water set point is calibrated .5°C below the boiling
point. Once calibrated the unit will resume normal
operations and the calibration data is saved.
The unit will not re-calibrate under normal
circumstances. If a repeated calibration is
required the following procedure should
be followed:
– turn the water supply off
– run the hot water until the hot tank is empty
– turn the power off for 5 seconds, then on
again
– turn water supply on
– the unit will then re-calibrate its boiling point.
Re-check Connections for leaks Explain
