    More Hygienic
    The proximity sensor removes the need to touch the spout, reducing the spread of germs and reducing the chance of cross-infection.

    Battery Override
    Your infrared soap dispenser is supplied with a backup battery pack. In the event of a power failure, the product will automatically switch to battery-operated mode to ensure the spout continues to function.

    Low Battery Warning
    When the batteries run low and the power falls below 3.9V the sensor light will flicker to indicate the batteries are running low and need replacing.
    When the batteries are exhausted the sensor light will not light up.

    Electrical Connections

    Regulations: The electrical installation must be carried out in accordance with the national electrical regulations and installed by a qualified person.

    Safety: In the interests of electrical safety a 30 mA residual current device (R.C.D not supplied) should be installed in the supply circuit. This may be part of a consumer unit or a separate unit.
    Before starting work on the electrical supply ensure the power supply is isolated.

    DO NOT allow the supply cord to contact hot surfaces. The cord should be safely routed and secured by cable clips.

    Connections: The power supply must be permanently connected to the fixed wiring of the mains supply using the factory fitted supply cord, via a switched fused spur off the ring main.
    The wires in the mains lead are coloured in accordance with the following code:
    Blue: Neutral
    Brown: Live

    As the colours of the wires in the mains lead of this appliance may not correspond with the coloured markings identifying the terminals in your connection unit proceed as follows;-
    The wire which is coloured blue must be connected to the terminal which is marked with the letter ‘N’ or is coloured black.
    The wire which is coloured brown must be connected to the terminal which is marked with the letter ‘L’ or is coloured red.


    1. Fit The Spout
    Fit the spout to the sink/basin ensuring the dispensing cable and sensor cable are threaded through the hole in the sink/basin.

    2. Secure Spout to Sink / Basin
    Screw the metal back nut onto the thread of the spout upto the underside of the sink/basin.
    Tighten backnut using a suitable spanner.

    3. Fit Wall Brackets
    Position the brackets onto the wall surface and mark the position of the fixing holes.
    Remove the brackets and drill suitable holes for the wall plugs supplied.
    Before drilling into walls, check that there are no hidden electrical wires, cables or water supply pipes. This can be checked with the aid of an electrical detector:

    If power tools are used do not forget to:
    - Wear eye protection
    - Unplug equipment after use
    Fit the wall plugs and position the brackets into position and secure using the screws provided.

    4. Attach Pump to Bottle
    Ensure the dispenser tube is located inside the bottle and push the pump down firmly onto the bottle until a loud ‘click’ is heard.
    To remove the pump from the bottle press the release button in on the side of the pump and pull the pump from the bottle.

    5. Connect Sensor Cable and Dispenser Cable
    Connect the sensor cable from the spout to the sensor cable on the pump. Push the two connections together and tighten the connecting ring to ensure the two connections are locked together.
    Connect the dispensing cable from the spout into the top connection on the pump.
    Push the threaded connection of the dispensing cable into the connection on the pump and tighten the nut ensuring it is fully tightened.
    A suitable spanner may be used to tighten the nut.

    6. Place Pump into Bracket
    The pump has a cut-out section which the wall bracket slots into.

    7. Connect Power Supply Cable
    Before starting any electrical work ensure the power supply is isolated.
    Wire the electrical power cable into a switched fused spur off the ring main.
    The blue wire should be wired to the neutral connection and the brown wire should be connected to the live connection.

    Important: The power lead must be permanently connected to the fixed wiring of the mains supply using the factory supplied power cable.
    Plug the power cable into the power cable on the pump.

    8. Inserting Batteries
    Remove the battery cover by loosening the screw in the top of the cover.
    Insert 4 x AA batteries into the battery box ensuring they are inserted the correct way.

    Only use 1.5V AA (LR6) Alkaline batteries (preferably => 2000mAh for good battery life).
    Replace the battery box cover and tighten the screw. Insert the battery box into the holder.
    Push the holder into the battery box wall bracket.


    Commissioning Sequence
    Before using the soap dispenser for the first time the following sequence must be carried out.
    Fill the bottle full of liquid soap.
    Locate the dispense button on the side of the pump. Press and hold the button until soap is dispensed from the spout. This will ensure the dispenser tube and cable are full of liquid soap.

    Selecting Volume Adjustment
    The soap dispenser has four dispense volume adjustment settings. Each adjustment setting dispenses a different volume of liquid soap.

    To adjust the volume of soap dispensed follow the steps below.
    Locate the volume adjustment switches under the rubber cover.
    Set the switches to the required position for the desired volume adjustment setting.
    Refer to the switch position diagrams.


    Using the Automatic Soap Dispenser
    Place the users hands under the spout within the sensing range.

    Once the users hands have been detected a small amout of liquid soap will be dispensed from the spout into the users hands.
