WATER CONNECTION
The system must be connected to the potable water supply network.
If the system includes a filtration system, ensure that all the filter elements are properly installed before
making any connection to the water supply.
Refer to the appropriate paragraph or instructions supplied with the filters for installation, maintenance and
expiry.
It is recommended to install a valve at the water input of the cooler, in order to isolate the system from the water
supply whenever it is necessary. When the customer is not able to service, it is recommended to install a device that
automatically stops water flow and isolates the product from the water circuit (our sales department is available for
further technical specifications).
No tools are required to connect the system to the drinking water tube. Connection is carried out easily and within
seconds, simply by inserting the tube directly into the rapid connection located on the back/side of the product.
This product can be supplied with ¼” rapid connections if the connections are white (or beige).
In this case, do not use 6 mm metric tubes as these are not suitable.
Before connecting the water tube be sure that there are no traces of impurities in the inlet rapid connection. A dust
cap may be present, if so, it is necessary to remove it before water tube connection.
The incoming water pressure must be between 0.250 MPa e 0.500 MPa
. The flow rate should not be less than 3
litres/minute.
Check that the pressure remains constant even while water is being dispensed or at least that variations
do not exceed 0.050 MPa. If this is not the case, reduce the length of the connection tube, or increase the
internal cross-section.
To ensure proper installation, it is recommended to use only certified food-grade tubes and fittings.
CAUTION: If incoming water pressure is unknown, a “water pressure reducer” must be installed and set to
0.250-0.300MPa. Again, check that the pressure is maintained within this range even while water is
dispensed, or that variations do not exceed 0.10
MPa
.
CAUTION: If an excessive drop in water pressure is detected during delivery, switch off the product
immediately and install it strictly in accordance with the above provisions.
Insufficient pressure causes damage to the pump in the water carbonation circuit, continuing intervention
of the electronic protection device and invalidation of the warranty.
