5.6 Water requirements
The supplied tap water must have the following conditions
:
•
Minimum pressure 200 kPa (2 bar)
•
Maximum pressure 500 kPa (5 bar)
•
Maximum water temperature 55 °C (130 °F)
•
Acidity pH 7.0 - 8.0
•
Chlorides less than 30 ppm
•
Use a sediment pre-filter or a strainer for the reduction of silica and other non-dissolved
sediments.
Water hardness and descaling filters:
•
A descaling filter is advised when the hardness of the water is > 4° dH (4 Grains/Gal).
•
A descaling filter is mandatory when the hardness of the water is > 20° dH (20 Grains/Gal).
Note that the cleaning capacity of the cleaning tablets will decrease with harder water
.
The by-pass of the descaling filter, if applicable, needs to be adjusted to zero.
Refer to the filters manual to determine the filter capacity. This filter capacity needs to be adjusted
in the manager parameters.
