Product Usage Instructions

Planning

Ensure all components are present and accounted for before starting the installation process.

External Power Supply Installation

1. Ensure the mains power supply is off before proceeding with installation.
2. Position the mounting box at least 500mm from the floor, considering moisture ingress and accessibility.
3. Follow NZ electrical regulations when installing the external power supply.
4. Secure the power supply via a current breaker before connecting the external supply.

Faucet Installation

1. Prepare the wall for hot and cold water connectors and power connections.
2. Fit brass connectors to the mains water supply ensuring equal pressure between hot and cold.
3. Install cover plates over brass connectors, pulling the power cable through the designated hole.
4. Attach the faucet body to the wall, being cautious of the power supply.
5. Connect the external power supply (24V outlet) to wago connectors on the faucet, ensuring correct polarity.

FAQ

Q: What should I do if there is a cold water failure?

A: The integrated safety stop on hot water will activate in case of cold water failure, ensuring user safety.

Q: How do I ensure the proper functioning of the sensor taps?

A: Make sure the active range is within 0.3 – 0.75 meters and that the automatic shut off after 5 minutes feature is functioning correctly.

General Information

• Designed for indoor use only. Do not be exposed to elements of nature.
• All plumbing and electrical connections must be made per AS/NZS standards.

Warnings

• Read all instructions before attempting to install this system. It is recommended a qualified & registered plumber completes the installation.
• Ensure pipe work is thoroughly flushed before installing the faucet (internal solenoid). Solenoid components are susceptible to debris and require additional flushing compared to a standard plumbing fixture.
• Consideration should be given to any regulations relating to an air gap, an air break, or a double-check valve to protect against backflow.

Operating Instructions and Parts Manual

• Please read carefully before attempting to assemble, install, operate, or maintain the product described. Protect yourself and others by observing all safety information. Failure to comply with instructions could result in personal injury and/or property damage.
• Retain instructions for future reference.

Planning

• Ensure an appropriate piping design (sizing etc). This will eliminate issues arising from flow, pressure, and water hammering.
• This tap requires the hot and cold pressure to be consistent with one another to ensure the thermostatic mixer functions correctly.
• Where appropriate install necessary filters, water hammering arrestors, and water pressure-reducing valves (recommended pressure 1 to 6 bar). This will minimize future maintenance.
• Install an isolating valve(s) to enable ease of future maintenance.

Components

Standard Functions

External Power Supply Installation

Important

• To be installed under all NZ electrical regulations. It must be carried out by a qualified professional.
• Positioning of the mounting box should be 500mm from the floor and consider:

1. Moisture ingress due to plumbing fault
2. Ongoing maintenance and accessibility

The mounting box can be surface mounted or within the service or ceiling cavity.

1. Ensure the mains power supply is off
2. Mark mounting point(s) on surface
3. Drill and insert appropriate wall anchors if required
4. Remove the cover from the mounting box
5. Fix the mounting box to the wall
6. Pass mains (230V) power supply into the mounting box via grommet and terminate accordingly
   • Note: The power supply should be secured via the current breaker before the external supply (not included)
7. Reinstall the cover of the mounting box and ensure sealed. Tighten the grommet to ensure snug around the cables

Faucet Installation

1. Prepare the wall for hot and cold water connectors and power connection
2. Fit off brass connectors directly to the mains water supply and ensure equal pressure between hot and cold
3. Fit cover plates over brass connectors, being sure to pull the power cable through the designated hole on the cover plate
4. Unscrew the security screw from the bottom left of the faucet body to release the end cap
5. Fit faucet body to the wall, being careful of the power supply cable
6. Thread the power cable via the end cap and pull right through
7. Connect external power (24V outlet) supply to wago connectors on the faucet (Note polarity: brown to brown, white to white)
8. Replace the end cap and secure the security screw
9. Fit the swivel arm on the faucet body and tighten it securely. Set the thermostat to the desired temperature
10. Do not come within the active range
11. Turn the power supply onIt is necessary, for the proper function, to keep the unit under constant voltage (don´t connect the power supply unit behind the switch to the light circuit)
12. Once power is turned on, the faucet will automatically adjust the sensing range during the first 10 seconds. The LED on the sensor will continually flash, do not come in active range during this time

Important

• Ensure hot and cold water pressure is equal for the thermostat to operate correctly.
• Pipework is required to be flushed thoroughly before faucet and solenoid installation. Foreign debris may reduce the level of flow and in some cases damage the solenoid valve.
• The sensor of the faucet must not be obstructed.
• Avoid positioning reflective objects or surfaces in front of the faucet sensor (when a sensor is facing the bottom of the basin). This can cause false activation i.e. mirrors opposite faucet. With wall-mounted faucets pay particular attention to the distance between the bottom of the basin and the faucet (minimum of 300mm) and the location and material of the basin waste (avoid mounting directly over the waste and/or choose non-reflective options).

Maintenance

• It is recommended that the solenoid valve and all filters be inspected for foreign debris and cleaned annually (more frequently if necessary)
• Clean faucet regularly using soapy water and a soft cloth or wet sponge
• DO NOT clean the faucet with any abrasive material or chlorine/acid-based cleaning product. This may damage the filter of the infrared sensor and/or the finishing of the faucet.
• Note: If you require to modify any of the factory settings please request the Sanela remote SLD03.
