Usage & Setup: Billi Quadra XL Levered Dispenser User Guide

Overview

The Quadra XL Levered Dispenser is a dual-water dispenser used with Billi Quadra and Quadra Plus systems to deliver boiling and chilled water from a single, space-saving tap. It is designed for kitchens and workspaces that need fast access to filtered water, simple controls, and built-in safety features.

This guide covers the XL levered model as well as the related XT and XR tap options where the manual shares operating and setup information. The Quadra XL Levered Dispenser is a good fit for households, offices, and shared spaces that want filtered drinking water with selectable temperature control and energy-saving modes.

Detailed Description

The Quadra XL Levered Dispenser uses position-sensitive levers for water delivery. The left-side red control handles hot or boiling water, while the right-side blue control handles cold water. The levers can be lifted or pressed, and lifting a lever allows continuous flow until the user releases it.

The dispenser will not deliver hot and cold water at the same time, and water does not flow if both levers are pressed together. The tap body also swivels, so it can be swung aside when extra sink space is needed, then returned to its central resting position for normal use.

For XT and XR versions, the dispenser uses capacitive touch buttons instead of levers. These models support momentary dispensing or continuous flow depending on how the buttons are pressed.

Safety

Boiling water can cause serious burns, so the dispenser should always be used carefully, especially in homes or workplaces with children. The manual recommends activating the childproof safety switch when young children are present.

• Install, operate, and maintain the system according to the manufacturer’s instructions.
• Have the appliance installed by a suitably qualified tradesperson.
• Use only for its intended purpose and only as directed.
• Do not use water that is microbiologically unsafe or of unknown quality unless it has been adequately disinfected.
• Do not allow children to play with the appliance.
• Do not reset the thermal cut-out until the heater has been checked by a qualified person.
• Do not connect a restrictor or pressure relief device to the vent pipe.
• Use only the supplied hose sets and do not reuse old or other-brand hose sets.
• If the water supply is turned off, unplug the power cord from the power point.
• Keep the unit away from areas where water jets may be used.
• Do not switch off power in very cold ambient conditions if the unit may fall below 4°C.

Setup and Operation

The Quadra XL Levered Dispenser supports several operating features, including timed start and stop, standby mode, temperature adjustment, and a childproof safety lock. A clear icon system shows the system state and alerts the user when action is needed.

Using the XL lever controls

• Left red lever: boiling or hot water.
• Right blue lever: chilled or cold water.
• Lift a lever for continuous flow.
• Press or release the lever to stop flow.
• Both levers pressed together will not dispense water.

Using XT and XR touch controls

• Red and blue touch buttons control boiling and chilled water.
• Press and hold for momentary delivery.
• Double tap for continuous flow.
• Pressing both buttons together will not dispense water.

Indicator lights and symbols

• Orange indicator: filter change due, or overdue when shown continuously.
• Red dot or ring: heating up to temperature, then on steadily when boiling water is ready.
• Blue dot or ring: chilling in progress, then on steadily when chilled water is ready.
• Green lightning bolt: time switch is active.
• Green moon and stars: standby mode is active.
• Red lock: child safety lock is enabled.

Initial setup and installation settings

Initial setup is intended for the installer and is used to define the operating parameters before regular use. The display shows the model, software version, serial number, day and date, current time, and current operating status.

Quadra Plus hot water function

On Quadra Plus models, the system supplies instant hot water through the sink mixer by blending boiling water from the internal tank with cold water. The delivered hot water can reach up to 50°C. If demand is higher than the system’s delivery capacity, the water may run cool and bubble temporarily, but extra boiling water remains available and recovery is quick.

Cleaning and Maintenance

The system is designed for low routine maintenance, with filter replacement being the main service item. During every filter change, inspect the fittings, tubing, and cupboard area for leaks, damage, or moisture.

• Wipe the dispenser with a damp cloth.
• Use a non-abrasive, non-solvent cleaner if needed.
• Do not pour water over the dispenser.
• Keep the under-bench side vents clear on air-cooled units.
• Maintain about 10 mm of air space around the module.
• Avoid storing items in a way that bends or damages the plastic pipework.
• Make sure access to the power switch and water supply tap stays clear.

Troubleshooting

The Quadra XL Levered Dispenser includes fault detection and diagnosis. When a problem occurs, the display shows a message and the HELP function can suggest simple checks.

• If the filter indicator flashes, the cartridge is due for replacement; continuous orange indication means it is overdue.
• If the cold-water flow becomes weak, the filter may be blocked and may need early replacement.
• If the system enters fault mode, both red and blue indicators flash yellow.
• If dirty water has recently been supplied to the plumbing, switch the unit off to protect the filter cartridge.
• If the unit has been idle for more than two days, run a flush before normal use; the first cold-water draw after restart may run for 90 seconds.
• If there is leakage around the filter after replacement, check the filter body, tubing, and the sensor area behind the filters and keep that area dry.

When changing the filter, remove any foam packing material before installation, remove the front cover, turn the unit to override off while leaving power on, replace the filter, allow the automatic flush to finish, then check carefully for leaks before returning the cover.

Pros & Cons

• Pros: Simple lever operation, clear status icons, adjustable temperatures, energy-saving modes, child safety lock, automatic filter monitoring, and a swiveling tap for better sink access.
• Pros: Low routine maintenance and a compact under-bench design with minimal ventilation demand.
• Cons: Requires regular filter replacement, careful installation, and attention to safety rules because it delivers boiling water.
• Cons: Some functions, including setup and scheduling, rely on navigating the display menu rather than using the tap alone.
