1.3 - WATER  TREATMENT

•

The hardness of the mains water supply conditions the frequency with which the DHW heat exchanger is
cleaned.

•

In hard water areas where the main water can exceed 15°f total hardness, a scale reducing device is recom-
mended. The choice of this device has to be made taking into consideration the characteristics of the water.

•

In order to improve the resistance to lime scale it is recommended to adjust the domestic hot water temperature
as near as possible to the one you really require.

•

We recommend you to check the state of cleanliness of the domestic hot water heat exchanger at the end of the
first year and subsequently, on the basis of the lime scale found, this period can be extended to two years.
