- Connect the water supply pipe to the water pump quick-release coupling (FIG.11-REF.1).
When the water pump is connected to a container for the first time (and after every time the hydraulic system is empties or after
an extended standstill) the pump is previously engaged, to prevent damage to the mechanical seals.
To check that the pump is engaged, when the cock is opened (FIG.11-REF.2) water should escape.
Different materials require different percentages of water; as an indication for GIOTTO:
- at least 600 l/h with cement-based materials,
- 1,000 l/h with gypsum-based materials.
The water flow rate used may shift from the indications given above in relation to the length of the piping line, wear of the pump
(auger and stator) and the experience of the user.
The water entering the water pump must be clear and free from impurities. If the water network does not guarantee the
necessary flow of water, obtain a container with suitable capacity (200 litres) with compensation function. The container must
have a cock with float, must be positioned high with respect to the parking surface of the machine and water must be withdrawn
at least 50 cm above the connection (FIG.11-REF.1).
