SERVICE INSTRUCTIONS

DE-SCALE

ENSURE THE UNIT IS SWITCHED OFF AND UNPLUGGED.
To gain access to the internals of the water tank, remove the front
panel and then the 4 screws on top of the boiler, and lift the lid
clear of the body.
Note: Whenever the body lid has been removed from the boiler a new
lid gasket may be required to ensure a steam-tight joint. Damage to the
unit caused by a poor lid seal is not covered by the warranty.
Scale deposits should be removed from all internal surfaces,
particularly the heating element, thermistor and level sensors by gently
tapping or scraping. If the deposits are soft, use a nylon pad and
flush out. Abrasive cleaning materials containing scouring powders
and detergents must not be used, as such materials can cause taste
problems.
The integral scale-inhibitor in every Calomax boiler allows for a manual
/ chemical-free descale. Caustic chemical de-scalants should not be
used.
IMPORTANT Before re-commissioning the boiler it is important
that all scale and moisture is removed from the level sensors
and insulating gaskets, to avoid a false signal being transmitted.
Failure to remove this scale and/or moisture will cause the sensor
to indicate to the PCB that water is covering the element, whether
or not water is present. In this situation the PCB will energise the
element causing failure. If in doubt, protect the element by hand
filling with water to the level of the draw-off tap before switching
on the electrical supply to the boiler.
