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.
- 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 32mm 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 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. Simply push out the piece as show in Diagram 5. This will allow the tap to move 45 degrees to the left and right.
-
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.
-
-
Fit Dispenser Head Assembly
a. Feed dispenser tubing and loom through centre hole in the following order: -
- Dispenser power cord.
-
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 is activated, check dispenser now swivels smoothly 45° in each direction.

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. -
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. -
Connect Dispenser Tubing and Electrical Plug
IMPORTANT: Boiling outlet (red), vent tube (grey) must not be kinked and must be installed with a continual fall and no sag.
Connect all tubing and electrical plug as shown in diagram 17 & 18.
Ensure correct orientation of dispenser power plug before insertion. Trim tubes to correct lengths using a sharp knife or plastic tube cutter. Avoid leaving excess tubing which will sag, trapping water. Fit spring clamps supplied to retain silicone rubber tubing to barbed fittings.
Commissioning
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.
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 willenter 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: Steam 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 0.5°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.
