7. Remove as much loose scale as possible
by hand.
8. Dissolve any scale that is difficult to remove using
a suitable de-scaling solution. Remember to
replace the drain plug before using the de-scaler.
9. Clean the level sensing probes and their white
insulators completely, using a non-metallic
scourer.
10. Ensure all traces of de-scaler are removed by
flushing with copious amounts of fresh water,
before using the boiler again.
11. It is preferable to install an effective scale reducer
or water softener. This will reduce the frequency
of de-scaling but will not remove scale
completely in some areas.
Draw-off Tap:
The draw-off tap components are subject to wear
& tear. We strongly recommend that the tap is
inspected periodically (at least once a year as part
of a general maintenance routine). It is advisable to
keep a spare tap spring and tap washer in case of
emergencies.

To ensure your service enquiry is handled as
efficiently as possible, please have the following
information available;
• Brief description of problem
• Product Type (model)
• Serial Number (label on under-side of
boiler-case). This is essential.
Guarantee
Your boiler is guaranteed for 12 months from date
of installation.
Our guarantee includes on site labour and parts
for problems caused by fault of manufacture and
component failure with the following exclusions:
• Problems caused by hard water and lime
scale. We regret we cannot be held responsible
for problems caused by hard water
Service Warning & Fault
Diagnostics:
The boiler is fitted with an intelligent fault diagnosing
system and can detect certain fault conditions
as follows:
FILLING (Flashing):
The white FILLING lamp flashes
to indicate water starvation - can be caused by either:
1) The boiler has not sensed a drop in temperature
after opening the cold water valve a number of times.
Most common cause is an interruption to the water
supply – check the stop valve and make sure there
are no kinks in the water supply hose. This can also
be caused by low mains water pressure. Shortly after
the water supply returns to normal, the message
will cease.
2) (Usually following initial commissioning or
subsequent re-commissioning after service/repair).
If once the boiler has been switched on, the circuit
has not sensed water on the bottom level sensor
within 6 minutes. Check that there is a water supply
to the boiler and make sure there are no kinks in the
hose or debris in the water inlet.
DE SCALE:
The white DE-SCALE lamp will illuminate
to indicate that the lower sensing probe has become
scaled up. The boiler will continue to operate working
on the upper level sensor. De-scale as soon as
possible as described below.
RESET:
The red RESET lamp will illuminate
to indicate that one of the two safety cut-outs
have activated:
Safety Controls:
The majority of possible faults have been covered
above. However, in certain circumstances, one of
two different safety controls within the boiler may
have activated;
1) Over-boil safety cut-out – activates if boiler
produces excess steam. This can be due to;
-
lime-scale within the tank,
-
a temporary interruption in the water supply.
-
a faulty temperature sensor or internal
component (triac).
2) The Boil-dry safety cut-out – activates if the
boiler has been boiled dry, for example, due
to lime-scale build-up or water starvation.
