• All the pipes must be securely fastened to the respective couplings.
Refer to fig. 2 for the hydraulic intake, delivery and bypass connections: this depicts the general layout
of a hypothetical machine incorporating the pump. Also refer to the following table:
CAUTION
• Follow the water mains connection instructions shown in the "INTENDED USE" paragraph and
in the specific manual of the series (→MS), with special reference to the priming depth and supply
pressure and temperature: in case of any doubts, contact a Skilled Technician.
• The pump suction unit must always be equipped with a suitably-sized filter: frequently make sure
this is clean in accordance with the blockage times tied to the specific operating conditions
of each application.
• The internal diameter of the intake and bypass pipes must be equal to the external diameter of the
intake and bypass couplings respectively. They must have a nominal pressure of 10 bar /145 psi
• The internal diameter of the delivery pipes must be equal to the external diameter of the delivery
couplings. Their nominal pressure must not below the maximum pressure of the pump
• Never operate the pump:
- without water supply;
- with salt water or water containing impurities: if this occurs, have it operate for a few minutes
with clean water.
WARNING
• Also follow the instructions contained in the manual of the machine in which the pump is
integrated with special reference to the parts relating to the safety precautions, any use of
personal protective equipment (safety goggles, ear muffs, face masks etc.) and handling.
• Comply with the safety information in the operating and maintenance manual of any optional
accessories that are used
• Before starting up the pump carefully read the instructions contained in its manuals and in the manual
in which the pump is integrated. In particular, make sure you have fully understood how the pump and
the machine in which it is integrated work as regards liquid on/off operations.
• The pump and the machine in which it is integrated are not intended to be used by people (including
children) with reduced physical, sensorial or mental capacities, or who lack the experience and expertise,
unless they are able to benefit, through the intermediation of a person responsible for their safety, from
supervision or instructions concerning the use of the pump and of the machine in which it is integrated.
• Children must be supervised to make sure they do not play with the pump and with the machine in
which it is integrated.
• Particular attention must be given to using the pump in environments where there are moving vehicles,
which could crush or damage any delivery pipe and sprinkler lance.
• Special care must be taken when using the pump in environments where there are moving vehicles
which could crush or damage any: delivery pipe, spray gun and lance.
• Before using the pump, put on individual protective gear and devices to ensure adequate protection
