What the installer will need
G A 13 Amp fused double pole isolating switch with a minimum contact gap of 3mm in each pole.
2
G Suitable length of 1.0mm three core multi strand PVC insulated mains cable that complies
with BS6500.
G Suitable lengths of 15mm copper pipe.
Where to locate the SB2
G We recommend that the unit is installed on a suitable wall, at shoulder height and over a
sink.
G Adjacent to the 13 Amp (240 V) double pole fused isolating switch.
G Available mains cold water supply and drainage facility.
G Do not install the SB2 within reach of a person using a bath or shower.
G Do not obstruct the ventilation channel in the backplate.

The unit must be connected to cold, mains fed, drinking water only. Pressure range between 0.7
Bar/69kPa (10psi) and 10.0 Bar/940kPa (140psi).
Do not connect to a storage tank
G Isolate the water supply.
G Lay in 15mm water supply pipe to the location of the inlet connection (Fig. 1). (Check that
the water supply position gives enough space under the unit for it to be used properly).
Flush through the water supply before making the final connection, so that any debris is
removed.
Note: The inlet elbow contains a flow regulator. THIS MUST BE USED IN THE INSTALLATION.
G Lay in 15mm drainage pipe to the location of the steam vent connection (Fig. 1). (Connection is
made using the push fit adaptor provided).
G The steam vent connection must be taken directly to the sink below, if there is one, or via
a tundish to a suitable drain. Note: The steam vent outlet also acts as an overflow. (If a sink is
used it must be able to withstand boiling water and have an overfill outlet).

Operating Instructions
General Product Description
2
The SB is a wall mounted, self calibrating and self filling boiling water heater. It can be used
for making cups of tea or coffee and even soups and hot snacks. A special condenser traps
steam and returns droplets to the tank, minimising waste and saving energy.
The water temperature is set and automatically maintained by the SB2 and the unit is powered
down with the Power button. Water is dispensed by rotating the front cover knob clockwise.
How to operate the SB2
G Make sure the electricity and water is turned on.
Fig. 6
Refer to Fig. 6
2
2
G Use the POWER button to switch the SB on and to power down. (The SB should be
switched off at the mains if the water is not required e.g. at weekends, holidays, etc).
POWER light
When the SB is on the POWER light will come on.
2
FULL light
2
The FULL light comes on when the tank is full of water. (The SB fills up automatically and this
can take up to 10 minutes if the tank is completely empty).
TEMPERATURE READY light
The TEMPERATURE READY light comes on when the water is hot enough to use. (This can
happen even when the tank is not completely full of water).

Please Note:
2
G The SB can take several minutes to reach the required temperature, depending on usage
and tank capacity.
2
G To avoid energy wastage, the SB will automatically reduce the temperature by 10ºC if the
2
unit is not used for more than 60 minutes. (The SB will automatically go back to boiling
when the water is used).
2
G When the SB is switched on at the local isolator and the POWER button is pressed, it will
start by self calibrating. This can take up to 20 minutes to complete and includes
automatically boiling the water for 30 seconds.
G When first installed, it is recommended that the initial tank of boiling water is fully
drawn off and discarded. Allow the tank to re-fill and the TEMPERATURE READY light to
2
come on, before using the SB .
Dispensing water from the SB2
Fig. 7a
Fig. 7b
G Place your cup under the red spout at the bottom of the unit.
G Turn the knob clockwise to fill your cup (Fig. 7b).
G Turn the knob anti-clockwise to OFF (Fig. 7a).
WARNING
2
G SCALDING HOT WATER can be dispensed from the SB .
G Never wash your hands directly from the unit.
G Some plastic cups can distort if they are filled with boiling water, so causing a danger
of scalding.
2
How to clean and descale your SB
G Before cleaning or descaling, switch off the electricity at the isolating switch.
G It is recommended that the SB surfaces are cleaned with a soft cloth.
2
G Do not use abrasive or solvent cleaning fluids.
DESCALING
G A qualified electrician should carry out the descaling.
G ENSURE THE MAINS ELECTRICITY SUPPLY IS ISOLATED.
If scale comes out with the hot water then the SB2 may need to be descaled. This is
done by removing the front cover and top condenser assembly and using a suitable
kettle descaler. Ensure unit is thoroughly flushed through after descaling.

Trouble shooting
2
SELF HELP (See Table 1) – If the SB is unsatisfactory, then make the following checks before
calling out the contractor. Any one of these adjustments could restore the performance.
Table 1
a) TEMPERATURE READY
light is not on
This is normal: The water has not reached the set temperature.
(See Table 3 on page 10 for approximate heat up times).
This is normal: Some water has been taken out of the
tank so it is no longer full, but the water temperature is
still hot enough to use. (The tank will automatically fill up).
b) TEMPERATURE READY
light is on but the
FULL light is off
This is normal: The tank has automatically filled itself
and the heater is still getting the water up to the boil.
(See Table 3 on page 10 for approximate heat up times).
c) The FULL light is on but
the TEMPERATURE
READY light is off
This is normal: The tank is still filling itself with water and the
heater is still getting up to the boil. (See table 3 on page 10 for
approximate heat up times).
d) The POWER light is on but
the TEMPERATURE READY
and FULL lights are both off

reduce the temperature by 10ºC if the unit is not used for
more than 60 minutes. (The SB will automatically go back to
2
boiling when the water is used).
Ensure that the electricity supply is switched on at the
isolator, then press the POWER button.
f) All the lights are out and the
POWER button does not work
The water in the tank has been drained out due to a high
demand. Wait for the FULL & TEMPERATURE READY lights to
come on again.
g) The water flowing from the
outlet is sometimes only a
trickle

When the SB is first switched on it can take up to 18 minutes
h) The SB takes a long time
to reach the Boil setting. (See Table 3 on page 10 for
approximate heat up times).
to reach the selected
temperature
Check that a pipe has been fitted to the steam vent. Contact
your installer if this is missing.
Use the POWER button to power down the unit and not the
main electrical isolator. (This will reduce the amount of steam
produced).

A new SB needs to be flushed out before being first used.
j) The water tastes different
We recommend that the initial tank of boiling water is fully
drawn off and discarded. Wait for the FULL & TEMPERATURE
READY lights to come on, before using the unit.
Scale has built up inside the tank. As with all water heaters
scale will build up inside the water tank. How quickly this
build up occurs will depend on the hardness of the water and

We recommend the use of in line resin filters to protect the
heater.

Professional Service (see table 2)
If the SELF HELP checks do not cover the symptom, you should seek professional help.
The following additional checklist is provided for the benefit of the qualified engineer.
WARNING: SWITCH OFF THE ELECTRICITY AT THE ISOLATING SWITCH BEFORE REMOVING
THE COVER TO MAKE CHECKS.
Table 2
a) Unit fails to heat the water
Check that the water supply is on and that its pressure is
between 0.7 Bar 69kPa (10 psi) and 10.0 Bar 940 kPa (140 psi).
Check circuit through solenoid coil.
Check circuit through the heating element.
Check circuit through float switch.
If defective then replace.
b) All the lights are out and the Ensure that the electricity supply is switched on at the isolator.
POWER button does not work
Ensure that the flying lead to the front cover is connected
properly (see Fig. 5a and Fig. 5b).
Check the supply to the PCB. If supply OK then change PCB.
c) Water flows continuously
from the steam vent pipe
Check that the float switch operates correctly and switches the
water solenoid on and off.
d) The water tank takes more
than 20 minutes to fill with
water
Check that the water supply is on and that its pressure is
between 0.7 Bar 69kPa (10 psi) and 10.0 Bar 940kPa (140 psi).
Check operation of the water solenoid and that water flows
into the tank at a rate between 0.3 Litres/min and 1 Litre/min.
Check circuit through the solenoid coil.
