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.
Garden hose must be at least 5/8 inch in di-
ameter.
