CONNECTION TO THE WATER SUPPLY
- The appliance must be connected to a potable
water supply. The water inlet pressure must be
between 150 kPa and 300 kPa. Use a pressure
reducer if the inlet pressure is above the
maximum permitted level.

upstream of the appliance in an easily accessible
point.
- Make sure the water circuit is free of ferrous
particles before connecting the filter and the
appliance.
- Seal any unused connectors with a plug.
