SAFETY

This appliance must be earthed. If the molded plug supplied is not used then ensure that the green/yellow cable is connected to suitable earth.
Risk of flooding. The hose supplied with this unit is non-toxic food quality tested to 190psi. However, a hose is not a permanent connection. It is, therefore, advisable to switch off the boiler and close the stopcock valve when the boiler is not in use, e.g. overnight, on weekends etc.
Risk of scalding. Beware of accidentally operating the water draw-off tap or push button, especially when cleaning the front of the boiler.
The utmost care has been taken in the manufacture and testing of this unit. 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.
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.
In the event any wires are damaged, such wires can only be replaced by experts or professional after service staff from the manufacturer, after service department or similar function departments.

INSTALLATION DETAILS

General installation

To be installed in locations where temperatures are between 5°C and 35°
Ensure that the appliance is placed on a flat horizontal surface.
Ensure that the appliance is installed where it can be observed by trained personnel.

Electrical installation

Electrical specification: 2.8kW 200-230Vac 50Hz
A moulded 13A plug is factory fitted. A suitable 13A outlet is all that is required.
For 200V installation ensure appropriate connection to suitable supply.

Plumbing installation procedure

Mains water pressure required (limits): 14.5-145psi (100-1000kPa)
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).
Where a flexible hose is to be used in the installation please use the new hose set supplied. Do not use old flexible hose sets for the instillation of this appliance.
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.
NOTE: Using a non-food grade 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.
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.
NOTE: On a 2L or 5L machine the ‘Power’ button light also acts as the “Ready/Status” indicator.
The “power on” light will glow green and the machine will fill to a safe level, above the elements, before heating.
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.
On a 2L or 5L machine, whilst the machine is above the safe level and filling, the “Ready/Status” light will glow orange.
On a 10L machine, whilst the machine is above the safe level and 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 2L allow approx. 10minutes. for 5L allow approx. 15 minutes and for 10L machines allow approx 30 minutes.
The boiler is now ready for use.

NOTE: Because the boiler is electronically controlled no priming is necessary. The element cannot switch on until a safe level of water is reached.

ECO Mode Operation

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 incorporate 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 minimising 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:
- Towards the end of the boilers operating period for a given day, switch the machine to ECO Mode. Whilst maintaining water at 96oC, the machine tank will slowly drop to half full, where it will remain.
- At the end of the machines operating period it should be turned ‘off’.
- During 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

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 the power supply.
Isolate machine from the water supply.
ALLOW TO COOL COMPLETELY!
Drain water from the 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. NOTE: 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.

Permissible mains inlet water pressure
Minimum 100kPa / 0.1MPa / 1bar / 14.5psi Maximum 1000kPa / 1MPa / 10bar / 145psi
