WATER SUPPLY

(Cold Water Only)

 CAUTION

When connecting the water inlet to
the water supply mains, local regula­tions of your water company must be
observed. In some areas the unit
must not be connected directly to the
public drinking water supply. This is
to ensure that there is no feedback of
chemicals into the water supply. Di­rect connection via a receiver tank or
backflow preventer, for example, is
permitted.
Dirt in the feed water will damage the
unit. To avoid this risk, we recom­mend fitting a water filter.
