Permissible mains inlet water pressure:
Minimum 20kPa / 0.02MPa / 0.2bar / 2.9psi
Maximum 1000kPa / 1MPa / 10bar / 145psi
The inlet water must be potable and free of contaminants.
Inlet water should be 5-30°C, pH 6.5-8.5, maximum chlorine content of 100 mg per
litre, total hardness of 60-180ppm. Do not connect the machine to pure reverse

Ensure that the equipment is installed according to local plumbing & water
regulations.
Covers shall only be removed by authorised personnel only. The appliance
must be fully disconnected from mains (the switch on the front panel is a
standby switch and does not switch mains voltage)
Warning. Live electrical voltages are present behind the cover(s)
marked with this symbol.

Warnings:
Installation should only be carried out by a competent service engineer.
This appliance must be placed/installed on a horizontal flat stable surface.
This appliance is not suitable for outdoor use.
The ambient temperatures this unit should operate within are 5ºC - 35ºC.
This appliance should not be installed in a tightly enclosed area (such as a
cupboard). Air should be able to freely circulate around it.
This appliance dispenses hot water at near boiling point and is a potential
scald/burn hazard.
Beware of accidentally operating the water draw off tap especially when cleaning
the front of the boiler.
Steam & hot water may discharge from the vent outlet at the bottom from of the
machine.
The vent outlet at the bottom of the machine is intended to drain condensate into
the supplied driptray. This vent must not be plugged, plumbed or obstructed in any
way.
This appliance 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
appliance by a person responsible for their safety.
Children should be supervised to ensure that they do not play with the appliance.
This appliance may be placed in self-service areas if attended to by trained
personnel.
The electrical power supply must be connected in accordance with the applicable
regulations of the country of installation.
The appliance must be fully disconnected from mains power before removing any
panels or during general servicing; the button on the front is standby only and does
not switch mains power on/off. (i.e. you must unplug fully at the power socket).
If the supply cord is damaged, it must be replaced by the manufacturer, its service
agent or similarly qualified persons in order to avoid a hazard.
Check your National water supply authorities for any specific requirements.
Check your National health/kitchen authorities for any specific requirements.
The new water inlet hose-set (if) supplied with the appliance is to be used.
Any old water inlet hose-set(s) should not be reused.
Risk of flooding. 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, weekends etc.
The utmost care has been taken in the manufacture and testing of this appliance.
Failure to install, maintain and/or operate this boiler 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 boiler always
contact the manufacturer or your own supplier for advice.
The default temperature set point of this machine is approx 96°C using this
machine at high altitudes could result in boiling and excess steam, with little water
being able to be dispensed. Contact the manufacturer in this case.
Before any attempt is made to move or service the boiler ensure it is unplugged,
and drained via the tap and allowed to full cool fully.

Installation details:
A suitable 230-240V power socket outlet is required in accordance with the local
regulations. Be sure other high power appliances are not on the same circuit
which could cause tripping.
Installation procedure:
Fit a stop valve and suitable fitting on a cold water line (e.g. 3/4" x 1/2" 311 or
washing machine type stop valve).
The boiler requires a suitable foodgrade inlet hose with 3/4” BSP female elbow
fitting which will attach to the underside of the boiler.
Make sure that the pre-attached sealing washer is fitted on both ends.
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 again.
Turn on water and check for leaks.
NOTE: Using a non-foodgrade hose (e.g. a washing machine hose) will
usually result in off-tastes & smells in the water, and can possibly be toxic.
Operating boiler for the first time:
Check that all installation procedures have been carried out, and all warnings
have been noted and understood.
Ensure water valve is on.
Connect to appropriate power supply (as per installation details above) and turn
power on at switch in the front of the machine.
The orange “power on” light (on the left, looking at the machine) will glow and
the machine will fill to a safe level, above the elements, before heating. The red
“Ready/Status” light on the right will cycle two 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 (approx. 25 mins). The
green “Ready/Status” light illuminates when the machine is both full and up to
normal operating temperature.
The boiler is now ready for use.
When full and connected to a mains supply of water the boiler can output
approx 10L in approx 2.5minutes. It will recover water at a rate of approx
450ml/minute. When water is drawn off the heat/fill cycle re-continues so no
cold water can be dispensed.
NOTE: Because the boiler is electronically controlled no priming is necessary.
The element cannot switch on until a safe level of water is reached.

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:

Check water pressure, if OK
then call service agent.
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. Beware of accidentally operating the
draw off tap 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. Machines typically need
descaling every 3-6 months. Descaling of the machine requires removal of panels
and must only be carried out by qualified service personnel who must read the full
warnings contained in this manual, and must contact the manufacturer for detailed
descaling instructions. Aggressive descaling agents can damage the stainless steel
tank. Citric acid based descaling agents are recommended, the tank must be fully
flushed through at least twice to remove all residues.
Date of Manufacture:
The first four numbers of the serial number indicate the month and year of
manufacture MMYY. The last numbers are an identification number unique to that
machine in that month. e.g. 07125555 -this machine was made in July 2012 with an
identification number of 5555.
