Notes:
- If the hose is new or has been unused for a long time, before connecting it make sure that the
water is clear and free of impurities.
- If the supply system does not provide both hot and cold water connections, the two hoses must be
connected together by means of the “Y” fitting provided with optional accessory T4260AC.
Fig. 147 – Water intake Y" connection, with filters fitted.
The characteristics of the intake water must comply with the requirements stated in the product’s
TECHNICAL SPECIFICATIONS tables.
MAINTENANCE OF WATER CHARACTERISTICS
Regular checks must be made (e.g. every 6 months/1 year) on the intake water to ensure that
the initial values are maintained, to allow the device or treatment system parameters to be
corrected if the characteristics change.
14.5.2 DEMINERALISED WATER REQUIREMENTS
optional connection, strongly recommended
If available, the use of demineralised water is recommended to ensure that washing is optimal from the
chemical point of view and for better elimination of residual salts from the mains water supply.
However, dirt residues will still be effectively removed even if ordinary mains water is used.
DEMINERALISED WATER NOT AVAILABLE
If demineralised water is not available, do not connect the relative hose to hot and/or cold water intakes.
Leave the “demineralised water" hose disconnected and contact the authorised engineer to have the
device’s parameters set correctly.
