Scale; Draining - Calomax ECLIPSE HS3C10 Installation, Operation And Service Instructions

SCALE

The production of scale is a natural phenomenon and commonly
occurs in hot water systems. The nature of the scale produced and its
rate of formation varies widely throughout the country.
To ensure continuous, reliable operation, the boiler should be regularly
de-scaled by a suitably qualified engineer.
The HS3C10 boiler benefits from an integral scale inhibitor; this is
not a scale eliminator and its effects will differ according to the water
quality in your area. To ensure trouble free operation, periodically
check for scale inside the boiling chamber. De-scaling may be required
within the first 12 months. This is not covered under the product's
warranty as it is not a fault.

DRAINING

Draining of the unit must only be carried out by authorised
competent persons. Very hot surfaces are present. It
is recommended to allow the unit to cool down before
draining. Ensure the boiler is switched off and unplugged.
To access the drain valve, you must remove the thumb tight screws from
the left-hand side panel and carefully unfold the silicone tube from inside
the base. DO NOT PULL THE SILICONE TUBE FROM THE COPPER
ELBOW. Remove the silicone end bung from the tube end and place
the tube into a sink drain or container vessel. Turn the drain valve anti-
clockwise to start the flow of water.
Care must be taken when draining the unit if the unit
has not been left to cool down. The silicone tube and
accompanying drain valve will become very hot.
Remember to turn the drain valve fully clockwise when finished to close
the drain valve. Push the silicone end bung back into the silicone tube
and place the silicone tube back inside the base unit. Replace the drain
access cover.
