5. Commissioning (rst power on)
• Ensure water supply is on.
• Switch power on.
• Automatic commissioning will then commence under the control of the electronic
circuit board. The (automatic) stages in commissioning are as follows:
• At rst power on, the water tank will completely ll with cold water through the
solenoid valve. This will take approximately 5 - 20 minutes depending on capacity of
the appliance.
• When the electronic level sensor detects that the tank is full of water, the heating
element is switched on.
• The status ring on the base of the tap stem will indicate the appliance is heating (red).
• When the water has reached operating temperature the commissioning phase ends
and the appliance switches to normal operating mode. The heating phase will take
approximately 5 - 20 minutes depending on capacity of the appliance.
• The status ring will now indicate the appliance is ready to use (green).
• In operating mode, the electronic circuit board optimises boiling water availability.
The circuit board prioritises heating over lling, adding cold water only when the
contents of the tank are already at operating temperature.
6. Operation
Parts of this appliance – especially the vent pipe and tap– can become very hot in
use and can also generate steam. Consider and avoid the risk of injury to people or
damage to property when installing the appliance.
This appliance can be used by children aged from 8 years and above and persons
with reduced physical, sensory or mental capabilities or lack of experience and
knowledge if they have been given supervision or instruction concerning use of the
appliance in a safe way and understand the hazards involved.
Children shall not play with the appliance.

7. Smart Technology
11
• The Microboil Smart is tted with a two way tap.
• For instant boiling water for cups of tea and coee gently pull the top of the tap
forward. Boiling water will ow until the tap handle is released. This mode of
operation gives precision control for safe lling.
• To ll larger items such as caetieres, tea pots or pans, rotate the tap 180 degrees and
gently pull down until the tap handle locks into a horizontal position. Boiling water
will ow until the tap is returned to the vertical position.

• The appliance incorporates Smart Technology which increases energy eciency.
• Sophisticated electronic algorithms learn and predict boiling water usage so the
appliance is on when you need it and o when you don’t (sleep mode).
• No time is wasted programming or reprogramming a timer as algorithms are
constantly updating if your usage pattern changes.
Status Ring
• A status ring on the base of the tap stem indicates ready or heating (green/ red). It
also indicates when the appliance is in sleep mode.
Caution Indicator
• The caution indicator is a highly visible warning alerting users the appliance contains
boiling water. This indicator will slowly blink while the appliance is lling the rst
time. It also indicates the appliance has mains power.
See troubleshooting (section 13) for more fault information.

8. Cleaning and Maintenance
The appliance should only be installed and maintained by a competent person in
accordance with any local electrical and plumbing regulations.
Cleaning and maintenance shall not be made by children without supervision.
Do not use abrasive or corrosive chemicals to clean this appliance.
Use a soft damp cloth when cleaning the cover, avoid excessive use of liquids.
It is recommended that the appliance is inspected periodically for signs of scale
build up in the tank and around the element. Damage resulting from scale build
up is not covered by the warranty.
Always switch electrical power o if the water supply needs to be disconnected
for more than a few minutes. Failure to do so can damage the solenoid valve.
• Periodically (at least every 6 months) remove internal lime-scale build up using a
standard domestic kettle de-scaling compound. Access to the tank and water level
probe are gained from a black plastic screw cap at the top of the tank under the top
section of insulation. The cap is accessed by removing the plastic locking clip and
pulling the insulation up and forward (see Diagrams 8 and 9).
Diagram 8
12

• To aid de-scaling, the appliance has a drain plug which can be found on the
underside of the water tank behind the bottom insulation. This is accessed by
removing the plastic clips and pulling the insulation down and forward (see Diagrams
10 and 11).

For some retro t installations where existing pipe work is to be used but the inlet and
vent is reversed, it is possible to switch the inlet and vent connections on the appliance to
suit. To reverse the inlet and vent positions the procedure is as follows.
• With the cover removed, unscrew the brass reducer connected to the solenoid valve.
• Unscrew the compression nut and olive and remove the brass nut securing the vent
connection part.
• Unscrew the 2 screws securing the solenoid valve and disconnect the wiring from the
solenoid valve. Once done remove the tube for the solenoid valve and then remove
the solenoid.
• Remove the tube from the top of the plastic vent temperature sensor housing and
unplug the thermistor connector from the top of the PCB.
• Remove the plastic vent temperature housing by pressing in the circular lock tab, this
can be done with a small screwdriver.
• The back plate has two mounting brackets but only one is folded up. The folded-up
bracket needs to be folded at and the bracket that was at needs bending up to 90
degrees.
• Ret the plastic vent temperature housing by pressing it down onto the newly folded
up bracket, this will snap into position. At the same time the brass section should be
slotted through the appropriate hole on its respective mounting bracket.
• Reconnect the thermistor connector at the top of the PCB making sure the wiring is
not tangled round the inlet and vent tubes.
• Ret the vent tube to the top of the plastic vent temperature housing and secure
with a cable tie. This tube must not be kinked or twisted in any way.
• Ret the brass securing nut to the thread on the vent connection and then ret the
compression olive and nut.
9. Advanced Information
The appliance should only be installed and maintained by a competent person in
accordance with any local electrical and plumbing regulations.
Always switch electrical power o if the water supply needs to be disconnected
for more than a few minutes. Failure to do so can damage the solenoid valve.
Reversing the Inlet and Vent Positions

15
The switches must only be used with the appliance isolated from the mains
electricity.
Control Board Settings
It is possible for the user to congure some aspects of the appliance’s behaviour. These
changes can be made by means of the switches located at the top right of the control
board inside the appliance.
Pattern Recognition
While the pattern recognition algorithm predicts usage with a high degree of accuracy
this feature may not be suitable for everyone’s needs, for example, if usage is highly
sporadic. The appliance is supplied with pattern recognition ON as default (see Diagram
13). To turn OFF slide to reverse the switch position, however this is the less energy
ecient option.
Calibration
Calibration ensures that boiling point is accurate depending on any given atmospheric
pressure, altitude and calibration drift in the thermistor and other components. As default
the appliance is supplied programmed to calibrate only when powered on (see Diagram
12). This means when the appliance is in sleep mode and therefore saving energy it will
not wake up and perform an auto calibration which is very wasteful of energy. Powering
on and o will always cause a recalibration. However, it is possible to change so the
appliance will calibrate once a week by sliding the switch to its reverse position.
• Place the solenoid through the remaining hole in the mounting bracket next to the
vent and secure with the two screws.
• Ret the brass reducer to the solenoid valve, it is best practice to renew the bre
washer when retting.
• Ret the inlet tube securing with a cable tie and ret the solenoid wires ensuring it
does not kink any tubing.
