Choose a dispenser from our standard XL Levered, the  XT Touch version which has no levers and a clean style with all operation via a touch pad at the top of the tap or the XR remote which has a separate control pad which can be mounted nearby the tap for greater design flexibility. All versions are available with the complete Boiling and Chilled range.

Water cooled or air cooled
Select our standard water cooled or nominate air cooled if preferred. If choosing air cooled don’t forget to allow for a ventilation grille, which we also have available.

Extension kits
In a situation where the underbench unit cannot be mounted directly below the tap, Billi offers a tubing extension kit for our Boiling and Chilled systems which allows the unit to be mounted up to 2 metres away, giving extra design flexibility. We also have an extension kit available for the mixer tap, again allowing the mixer tap to be mounted up to 2 metres away from the underbench unit.

Premium filtration
Unless specified, the standard filtration in the Quadra Plus is 5 micron, which provides a high level of water quality whilst maintaining reasonable filter life. We also offer sub micron and premium sub micron filtration for even greater water purity and these filtration options are available with our units when originally supplied.

Quadra Plus - FAQS

Absolutely. In fact your dispenser can be installed up to 2.0m from its undersink water filter. Remember, there will be a boiling water delay with a long extension.

You will save space with Quadra Plus, because it comes with a sink mixer tap and supplies its own hot water.  This will eliminate the need for a separate hot water service, thereby creating extra space.

No. The Quadra Plus comes as a complete kit including a sink mixer. It is a special type of mixer to allow it to function with the underbench system, we do however offer a couple of different mixer design options.

We recommend a new filter at least every 6-12 months, depending on usage and water quality.

Yes.  You should always use the correct filter for your water system.

Yes. As filters catch contaminants, they become soiled.  Billi undersink water systems use mains pressure, so reduced chilled water flow indicates you should change filters.

The indicator lights tell you what’s going on.  Flashing red means boiling water hasn’t reached 99°C yet.  Flashing blue means water hasn’t chilled to set temperature.  Both lights will glow solid when this happens.

The orange light will flash continually when your water filter needs changing.

The undersink chilling unit may need a minor service.  Change filters before calling a technician.

The heating element may have blown or overloaded.  Call an authorised Billi agent to repair your undersink water system.

Contaminants collected in your undersink filter become concentrated when filters reach the end of their life and can affect water taste. Ensure that the filter is replaced at least every 12 months or 6,000 litres.

Push the SELECT button, then arrow down to OPTIONS.  Push the SELECT button and set Safety Switch to ON.  Touch the indent on the black panel on the back of the tap to allow for a short boiling water flow.

If the Billi dispenser lights are illuminated, your Quadra Plus water system is on.
