FIRST START-UP
Before starting the system, read this documentation and that contained in the pump manual with care.
The system must be checked and put into service by qualified staff who meet the technical requirements specified in the safety
regulations concerning the design, installation and maintenance of technical systems in the country where the product is
installed.
Always refer to the pump manual and the instructions
supplied with the electrical panel
Before starting the electric pump, check that the tank system
and pipelines are free from residues or other material which
may prevent the system from operating correctly.
Before the pump is put into operation, the tank must be filled
with the liquid to be pumped at least up to a depth level with
the top of the pump motor.
The pump must never suck in air!
The flow of liquid from the various users must not interfere with correct operation of the float switches in the tank.
In this phase, you may leave the cut-off valve on the inlet line shut and fill the lifting station with
clean water.
•
Check that the system's rated voltage is the same as the control panel power supply
voltage.
Check that a safety circuit breaker with suitable thermal protection is installed upstream
•
of the pump control panel supplied with the system.
Check that the current overload switch of each pump (thermal protector) on the control
•
panel supplied with the system is properly set. The pump thermal protector switch is
not set in the factory so it must be set in strict accordance with the procedure specified
in the electrical panel instruction manual provided.
For three-phase electric pumps, check that the impeller turns in the correct direction.
•
Also refer to the electric pump manual.
Check that the float switch tripping levels are correct and modify them if necessary to
•
meet the system's actual requirements.
•
When two electric pumps are installed, the float switches must be set so that the
second pump starts after the first and only if the latter is unable to transfer all the liquid
arriving from the various inlets to the sewer.
Check that the pump cannot be deprimed during operation.
•
Check that the number of starts per hour is compatible with the characteristics of the
•
system components.
Open the cut-off valve on the delivery pipeline and check that the pipeline connections are firm
and perfectly watertight, and that the electric pump is operating correctly. Also check that the
electric pump is primed.
Open the cut-off valve on the inlet pipeline and check that the station is operating correctly.
Check that the system is operating correctly and put it into service. Close the station's cover/s,
screwing it or them into place.
