1. Make sure that the tank is filled with a quantity of oil greater than the quantity to be supplied running dry could damage the pump e Turn the on switch present on some pump models or the start stop switch installed on the electrical power line e Open the delivery valve or activate the delivery nozzle gripping it securely ZA ATTENTION Fluid exits at high pressure from a delivery nozzle fed by the pump Never point the outlet of the nozzle towards any part of the body Close the delivery nozzle or the line valve to stop delivery the pump will automatically enter by pass mode ZA ATTENTION Functioning with the delivery closed is only allowed for brief periods 2 to 3minutes maximum functioning under nominal conditions in limited to a work cycle of 30 minutes If this time is exceeded you have to run off the pump and wait for it to cool after use make sure the pump us turned off Stop the pump I PROBLEMS AND SOLUTIONS PROBLEM POSSIBLE CAUSE CORRECTIVE ACTION Motor does not turn Lack of electric power Check electrical connections and the safety systems Rotor jammed Check for possible damage or obstruction of the rotating components Motor problems Contact the service department Fuse burnt out Replace the fuse Motor turns slowly when starting Low voltage from the electrical power supply Adjust the voltage within anticipated limits Excessive oil viscosity2.

3. Fix the pump using screws of a diameter suitable for the provided fixing holes as indicated in the drawing Dimensions and weights ZA ATTENTION THE MOTORS ARE NOT OF AN ANTI EXPLOSIVE TYPE Do not install them where inflammable vapours could be present AN ATTENTION It is the installer s responsibility to provide the line accessories necessary for the safe and proper functioning of the pump The use of accessories that are inappropriate for use with oil can cause damage to the pump or people as well as pollution G INITIAL START UP The pumps are self priming and therefore able to draw oil from the tank even when the suction hose is empty on start up The priming height distance between the surface of the oil and the inlet opening must not exceed 2 5 meters ZN ATTENTION Wetting the pump Before starting the pump wet the inside of the pump body with oil through the inlet and outlet openings If the pump is already installed the operation can be performed by removing the cover of the chamber filling the internal chamber with oil and placing the cover again paying attention to the O ring seal In the priming phase the pump must blow the air that was initially present in the tubing into the line therefore it is necessary to keep the delivery open When the tube is filled with oil the purging phase is concluded ZA ATTENTION If a foot valve was not installed install the pump in a position so that oil is always

8. ity of the oil itself with the temperature Specifically e The minimum temperature allowed 10 C could cause the viscosity of some oils to greatly exceed the maximum allowed with the consequence that the static torque required during the starting of the pump would be excessive risking overload and damage to the pump e The maximum temperature allowed 60 C could on the other hand cause the viscosity of some oils to drop well below the minimum allowed causing a degradation in performance with obvious reductions in flow rate as the back pressure increases D 2 ELECTRICAL POWER SUPPLY Depending on the model the pump must be supplied by a continuous current line whose nominal values are shown in the table in Paragraph C TECHNICAL INFORMATION The maximum acceptable variations from the electrical parameters are Voltage 5 of the nominal value ZA ATTENTION Power from lines with values outside of the indicated limits can damage the electrical components D 3 WORKING CYCLE The pumps are designed for INTERMITTENT use with a 30 minute work cycle under conditions of maximum back pressure ZN ATTENTION Functioning under by pass conditions only allowed for brief periods of time 2 3minutes maximum after a work cycle of 30 minutes wait for the motor to cool D 4 FLUID ALLOWED FLUID NOT ALLOWED ALLOWED Oil with a Viscosity from 50 to 600cst at working temperature NOT ALLOWED RELATED DANGER Gasoline P
9. present in the gear chamber If the foot valve seal is not perfectly tight the suction tube may be emptied and the operation of initial start up described above must be repeated The priming phase may last from several seconds to a few minutes depending on the characteristics of the system If this phase is excessively prolonged stop the pump and verify e That the pump is not running completely dry That the suction hose guarantees against air infiltration and is correctly immersed in the fluid to be drawn That the filter in the suction circuit if any is nit blocked That the delivery hose allows for the easy evacuation of the air That the priming height is not greater than 2 5 meters The exact rotation direction of the motor it must be in a counter clockwise considering the motor from pos 1 of the exploded diagram When priming has occurred after reattaching the delivery nozzle verify that the pump is functioning within the expected ranges possibly checking that under conditions of maximum flow the energy drawn by the motor falls within the values indicated on the label H DAILY USE NO particular preliminary operation is required for every day use of these pumps e Before starting the pump make sure that the ultimate shut off device delivery nozzle or line valve is closed If the delivery has no shut off device free delivery make sure that it is correctly positioned and appropriately attached to the delivery tank
