HYDRAULIC CONNECTIONS
Warning! Avoid restricting or sharp bends in the suction and injection pipes, as they may affect the performance and
durability of the pump itself.
Suction line:
Connect the suction tube (b) to the suction connection (a) and tighten the
threaded nut (c).
Injection line:
Connect the injection tube (e) to the injection connection (d) and tighten
the threaded nut (f).
ELECTRICAL CONNECTIONS
Warning! Connection to the mains must be carried out in strict compliance with all the pertinent rules
and regulations.
Warning! Before powering the pump verify that all electrical and plumbing connections have been properly made.
Power the pump following the values of voltage and power consumption indicated on the pump label, and using the power
cable that comes prewired at the factory.
MAINTENANCE AND STORAGE
The periodic maintenance operations are essential for the proper functioning of the pump and its duration.
These operations must be performed in a systematic and thorough way, following the information below:
-
Periodically check the level of the liquid to be dosed, to prevent the pump from running empty.
-
Check that the suction and injection tubes do not contain impurities, as they may cause damage to the pipe and
anomalies in the flow rate.
-
Schedule a general check of the pump functioning, especially when dosing aggressive liquids.
-
Regularly monitor the condition of the filter, where clogging can cause a decrease in the flow rate.
ADJUSTMENT
The pump flow rate can be adjusted from 0 to 100% through dedicated trimmer (B). By turning the
trimmer you can adjust the rotation speed of the motor and therefore the pump flow rate.
The LED (A) indicates the pump status: a yellow light means that the pump is ON but it is not dosing
(B trimmer in position of minimum rotation). The LED turns orange increasingly intense as the
trimmer B is rotated toward the maximum flow position.
