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.
A scale reducer can reduce the build up of scaling, but may not stop it altogether. Descaling of
the machine should ideally be carried out by qualified service personnel.
Cautions and safety tips:
This appliance must be earthed.
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 boiler
and close the stopcock valve when boiler is not in use, e.g. overnight, weekends etc.
Risk of scalding. Beware of accidentally pressing the font buttons while cleaning the fonts.
The utmost care has been taken in the manufacture and testing of this unit. Failure to install,
mai
ntain 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 suppli er for advice.
