Introduction
The information provided in this manual is intended to assist in the installation and mainte-
nance of the MIX range of hot water boilers. Please read the instructions carefully to prevent
accidents and ensure an efficient installation. This manual is not a substitute for any safety
instructions or technical data affixed to the machine or its packaging. All information in this
manual is current at the time of publication and is subject to change without notice. The
company accepts no responsibility for any damage or injury caused by incorrect or unrea-
sonable installation and operation.
Safety
When using electrical appliances, basic safety precautions should always be followed to pre-
vent the risk of fire, electric shock, burns, or other injuries or damages.
• Read all operating and safety instructions carefully.
• This appliance must be placed/installed on a horizontal flat stable surface.
• The ambient temperatures this appliance should operate within are 5 °C - 35 °C.
• This appliance may be placed in self-service areas if attended to by trained personnel.
• The hose supplied with the boiler is non-toxic food quality tested to 190psi. However, a hose
is not a permanent connection. It is, therefore, advisable to switch off boiler and close the
stopcock valve when boiler is not in use, e.g. overnight etc.
• The utmost care has been taken in the manufacture and testing of this machine. Failure to
install, maintain and / or operate this machine according to the manufacturer’s instructions
may result in conditions that can cause injury or damage to property. If in any doubt about
the serviceability of the machine always contact the manufacturer or your own supplier for
advice.
• This machine is not intended for use by persons (including children) with reduced physical,
sensory, or mental capabilities, or lack of experience and knowledge, unless they have been
given supervision or instruction concerning use of the machine by a person responsible for
their safety.
• Children should be supervised to ensure that they do not play with the machine.
• In the event where any wires are damaged, such wires can only be replaced by qualified
service technicians.
• CAUTION - Risk of fire and electric shock. Only to be used with manufacturer’s specified
power cord set. Marco p/n 1501487 (USA), 1501488 (EU), 1501489 (UK/Ire).
• This appliance should not be installed in an area where a water jet could be used to clean it.
• Access to the service area of the appliance is restricted to persons having knowledge and
practical experience of the appliance and the relevant safety and hygiene requirements.

Information
Electrical Installation Procedure
When installing the machine, always observe the local regulations and standards. The ap-
pliance is supplied with a moulded power cord. A suitable mains power supply socket should
be available within easy access of the appliance so that it can be disconnected easily after
install.
Plumbing Installation Procedure
• Ensure that the equipment is installed according to local plumbing & water regulations.
Mains water pressure required (limits): 14.5 -145psi (100 -1000kPa, 0.1 - 1MPa).
• 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).
• Turn on the water to flush any impurities, dust etc from the inlet hose and water pipe. Allow
several litres through. Especially for new installations.
• Connect the hose to the inlet valve of the boiler. Make sure a sealing washer is fitted.
• Turn on water and check for leaks.
Backflow Prevention
This equipment must be installed with adequate backflow protection to comply with all ap-
plicable federal, state and local codes.
Maintenance
This machine has been designed to give many years of trouble free service. The only regular
maintenance required is occasional de-scaling.
Descale Procedure
• Isolate machine from power supply.
• Isolate machine from water supply.
• ALLOW TO COOL COMPLETELY!
• Drain water from machine.
• Remove lid.
• Clean the water level probes with scotch brite.
• 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.
• See page 18 of this manual for further details.

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 per-
sonnel.
Operating Boiler For The First Time
• Check that all installation procedures have been carried out.
• Ensure water valve is on.
• Plug boiler into suitable socket.
• Turn on the power switch.
The “Wait” progress circle will be visible on the screen and the machine will fill to a safe
level, above the elements, before heating.
The “Ready” tick will come up on screen when the machine is full and up to normal operat-
ing temperature.
The boiler is now ready for use – the display will show the button settings and the “Ready”
status tick.
• The Boiler may now be used to dispense Hot Water to the preset factory settings.
NOTE: Because the boiler is electronically controlled no priming is necessary.
The element cannot switch on until a safe level of water is reached.
