• Before connection, make sure that the tubing and the suction tank are free of dirt and thread residue that could damage the pump and its accessories. • Before connecting the delivery tube, partially fill the pump body with diesel fuel to facilitate priming. • Do not use conical threaded joints that could damage the threaded pump openings if excessively tightened. • The pump is not provided with any filter. Always install suction filter (on all of the models it is included).
proper wetting of the pump. The installation of a foot valve is recommended to prevent the emptying of the suction tube and to keep the pump wet. In this way, the pump will subsequently always start up immediately. When the system is functioning, the pump can work with pressure at the inlet as high as 0.5bar/7PSI, beyond which cavitation phenomena can begin, with a consequent loss of flow rate and increase of system noise.
ATTENTION! IT IS THE INSTALLER’S RESPONSIBILITY TO PREFORM THE ELECTRICAL CONNECTIONS WITH RESPECT FOR THE APPLICABLE REGULATIONS. Respect the following (not exhaustive) instructions to ensure a proper electrical installation: • During installation and maintenance, make sure that the electric supply lines are not live.
• That the suction height does not exceed 2m. (if the height exceeds 2m, fill the suction hose with fluid); • That the delivery tube is allowing the evacuation of the air. When priming has occurred, verify that the pump is operating within the anticipated range, in particular: • That under conditions of maximum back pressure, the power absorption of the motor stays within the values shown on the identification plate; • That the suction pressure is not greater than 0.
