—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 1and
3 for clearances around the 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 water supply pressure:
Min. 250kPa, max. 1000kPa.
Supply temp: 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.
IMPORTANT: Insufficient ventilation will
cause inefficient refrigeration system
operation, increasing power usage and
will void unit warranty.
—Power Requirements
A single 10 amp standard power outlet is
required. All B-5000 units are supplied with
a 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 ø35mm.
—Stainless Steel Sinktop
A suitable 35mm 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 54mm
Cut 35mm 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 35mm 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 granite or marble benchtops we
recommend you use 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. Push out the
piece as shown in Diagram 5. This will allow
the tap to move 45° to the left and right.
3. Fit Dispenser Base
a. Cut a 35mm 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.
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.

Installing underbench module.
XL, XT, XR.
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.
This is particularly important with air-cooled
models. Ensure there is adequate access to
service the unit.
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) and vent
tube (grey) must not be kinked and must
be installed with a continual fall.

Commissioning.
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.
