This Manual remains the property of the Manufacturer; it may not be reproduced or copied, even partially.
For further information on connections refer to the Operating and Maintenance Manual for the main
machine incorporating the motorpump. These connections must be made by qualified staff.
5.2 Pre-commissioning instructions
A series of checks and controls must be completed before starting up the motorpump for the first time in order to prevent errors or
accidents during commissioning:
Check the machine was not damaged during assembly, installation and transport (check its stability, screws and/or bolts
are tight, mechanical parts/gears are coupled correctly);
If you notice any leaks from pressurised pipes, stop the pump immediately and find and solve what is causing the leak
Before starting up the pump, make sure the oil is up to level. We recommend the first oil change within the first 50 hours of
operation. Subsequent oil changes should take place every 500 hours, or more often in case of heavy use. The type of oil to
use for our pumps is SAE 10/40W, as indicated on the specifications plate.
Replace the oil cap used for shipment with the cap with the dipstick and bleed supplied.
Always comply with the safety instructions in section 3.
Failure to comply with these operating conditions invalidates the guarantee.
If the equipment does not appear capable of running safely and correctly, TAKE IT OUT OF SERVICE until it
has been repaired or any damaged parts have been replaced.
After the installer has completed all of the necessary connections, he will complete a series of tests to check all of the devices
fitted are operating properly:
After starting up the pump, aid priming by keeping the delivery line open (lance). Do not let the pump run dry: this can result
in rapid seal wear and invalidates the warranty.
After use, run the pump with clean water for several minutes. Do not use the pump at very low temperatures. To prevent
freezing, run the pump dry for about 20 seconds to drain the pipes.
Do not exceed ±5% of the voltage and ±1% of the frequency shown on the specifications plate of the motor.
When Y/ start-up is used the start-up time with the Y-connected winding must allow the motor to reach the rpm in a
stable manner and then immediately to the connection.
Check that the motor has not absorbed humidity by measuring the insulation resistance (R phase - ground better than
10MΩ). Take particular care to do this following long periods of downtime. Check the condensation outlet.
5.3 Long periods of inactivity
In case of long periods of inactivity, follow the instructions below:
Run the pump with clean water for several minutes.
Run the pump dry for about 10 seconds with the delivery line open (lance) to drain the pump and the delivery circuit and
prevent the formation of scale
Clean the pump with water and solvents authorised by current legal standards
Dry the pump using compressed air
Grease any unpainted parts
Do not let the system come into contact with corrosive substances.
Keep the motorpump in a dry place at a humidity level lower than 90% and protect it from impacts, vibration, stresses
and jumps in temperature
The properties of mineral oils are impaired if they are not used or remain inactive for more than six
months, and so must be replaced.
