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.

Power Requirements

A single 10 amp standard power
outlet is required. All B-5000 units supplied
with 1 metre flex cord and plug.

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.

Installing the dispenser
XL, XT, XR.

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. 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.

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.
