physical, sensory, or mental capabilities, or lack of experience and knowlodge, unless they
have been given supervision or instruction concerning use of the appliance by a person
responsible for their safety.
•Children should be supervised to ensure that they do not play with the appliance
•In the event any wires are damaged, such wires can only be replaced by experts or
professional afterservice staff from the manufacturer,afterservice department or similiar
function departments
INSTALLATION DETAILS:
Electrical installation:
•Electrical specification: 2.8kW-230V-50Hz
•A moulded 13A plug is factory fitted. A suitable 13A outlet is all that is required.
Plumbing installation procedure:
•Mains water pressure required (limits): 5-50psi (35-345kPa)
•Fit a stop Valve on a cold water line and attach a 3/4" BSP male fitting,
•(e.g. 3/4" x 1/2" 311 or washing machine type stop valve).
•Connect straight tailpiece of the hose to the stop valve fitting. Make sure that the pre-attached
sealing washer is fitted.
•Turn on the water to flush any impurities, dust etc from the inlet hose and water pipe. Allow
several gallons through.
•Connect right-angled tailpiece of the hose to the inlet valve of the boiler (again 3/4" BSP).
Make sure the sealing washer is fitted here also.
•Turn on water and check for leaks.
Operating boiler for the first time:
•Check that all installation procedures have been carried out.
•Ensure water valve is on.
•Plug boiler into 13A socket and press power button on the front of the machine marked
‘Power’. Refer to Figure 1.
•The “power on” light will glow green and the machine will fill to a safe level, above the
elements, before heating. The display will show the current water temperature and the status “
Filling…”
•The “Ready/Status” light will cycle two red flashes while the machine is filling to the safe level.
•After this amount of water has heated to about 96ºC the boiler will draw more water in until the
temperature drops by 1 or 2 degrees. The boiler will then heat again. This heat fill cycle
continues until the boiler is full.
•While filling, the “Ready/Status” light will remain blank.
•The “Ready/Status” light will glow green when the machine is both full and up to normal
operating temperature. For 10L machines allow approx 30 minutes.

•The boiler is now ready for use – the display will show the Water Temperature and the status “
READY”.
•The Boiler may now be used to dispense Hot Water to the preset factory settings.

Modes of Operations [ Service setup setting 5 ]:
Modes of OPERATION - This boiler can operate in 3 different modes.
HEAT FILL – Standard operation the boiler will take in water until the
temperature in the tank drops, the inlet will close and the heating element is
activated. When the temperature reaches the set temperature the inlet will
reopen to take in more water. This cycle will continue until the Tank is Full.
This mode is used to ensure that the water temperature is controlled within set
values.
CONTINUOUS MODE – In this mode the boiler will take in water and activate
the element until the tank is full and the temperature has reached the set
temperature. Typically used in high demand situations where the temperature
stability is not primary concern.
COOL Mode – In this mode the temperature can be adjusted up or down
[function 1.] while in operation. Depending on the water level in the tank
selecting a lower temperature will cause either a message to “DISPENSE
WATER TO COOL THE TANK” or will automatically take in cooler water to
reduce the temperature to the new set temperature. In applications where
selecting different temperatures frequently is required this Cool Mode is best
selected.
Note in the Cool Mode this boiler will operate as a 5 ltr and not as a 10 ltr unit.
MANUAL FILL – if the boiler is not plumbed into a water supply the operator
must select Manual Fill mode for best operation of the boiler. In this mode the
water is added manually by the operator.
ECO Mode Operation:
Note In the COOL FILL mode [ see Service setup setting 5] the ECO Mode is
automatically selected.
•All ECO Boilers use high grade insulation and it is applied to give a significant energy usage
improvement over a standard water boiler.
•The 10L ECO Boiler variants also incoprate a ½ tank ‘ECO mode’ function.
•To enable the ‘ECO Mode’ press the button located below the ‘Ready’ indicator so that the leaf
symbol illuminates green.
•This mode saves energy by mimimising the energy wasted during machine down-time.
•NOTE: The ECO mode is most effective in installations where the machine has a regular ‘off’
period.
•To achieve the most benefit from the energy saving ‘ECO Mode’ on your ECO boiler unit (10L
variants only), the following method should be employed:
oTowards the end of the boilers operating period for a given day, switch the machine to
ECO Mode. Whilst maintaing water at 96oC, the machine tank will slowly drop to half
full, where it will remain.
oAt the end of the machines operating period it should the be turned ‘off’.
oDuring the ‘off’ period as there is less water in the tank there will be less energy lost to
the surrounding environment resulting in an energy saving.
•To disable simply press the ‘ECO Mode’ button again so that the leaf symbol is not illuminated

TROUBLESHOOTING:
The Ready/Status light signals various errors or problems. A cycle of red flashes indicates an error.
The number of flashes in a cycle corresponds to the symptom in the table below:
Status/Diagnostic light guide:
No of
flashes Symptom Action required
2 Water level below elements. Normal
when machine first fills. Check water pressure , if this is OK then call service agent.
3 Temperature sensor failure (o/c) Call service agent
4 Water not heating Call service agent
5 Temperature sensor failure (s/c) Call service agent
6 Machine not filling Check water pressure, if OK then call service
agent.
MAINTENANCE:
This machine has been designed to give many years of trouble free service.
The only regular maintenance required is occasional de-scaling.
Descaling Procedure:
•Isolate machine from power supply.
•Isolate machine from water supply.
•ALLOW TO COOL COMPLETELY!
•Drain water from machine.
•Remove all lids.
•Remove as much scale as possible by hand, paying particular attention to level probes
(White plastic with steel tab). Be very careful not to damage any attachments.
•Use ScaleKleen, Marco part No. 8000270 or similar. Follow instructions carefully.
•Thoroughly clean and flush the machine before re-use.
•Follow installation and first time operation instructions.
CLEANING:
The exterior of these machines may be cleaned with a damp cloth and a light detergent. Do not use
abrasive cloths or creams, as this will spoil the finish of the machine. Do not use a water jet or spray.
NB: Beware of accidentally operating the draw off tap or push button when cleaning the front of the
machine.
LIMESCALE:
In common with all water boiler manufacturers, service calls resulting from limescale are not covered
by warranty. Fitting a scale reducer is recommended, especially in hard water areas. This can
reduce the build-up of scale but may not stop it altogether. The frequency that descaling is required
depends on the local water supply; hard water areas need more attention. Descaling of the machine
should ideally be carried out by qualified service personnel.

ACCESS TO INTERNAL COMPONENTS:
