8. STARTUP AND OPERATION

8.1. Preliminary checks before start-up of the
pump
Do not start-up the device in case of damaged parts.
8.2. Parameters to be set at the start-up
The electric pump is already set with all the operating
parameters, therefore it is not necessary to modify any
parameters for operation.
ATTENTION: at the first starting check that with all the
taps closed the system stops. If the pump do not stop
change the stop pressure (UP01) according with the
system needs.
8.3. Suction pressure set-up
The system allows the set of pumps suction pressure.
To set the pumps suction pressure, parameter AP01
must be changed.
ATTENTION: once the parameter AP01 has been
modified it is necessary to modify the parameters
UP01 and UP02 so that they are suitable for the
application and guarantee the correct start and stop
of the system (during programming the product will
suggest the values of the first attempt).
ATTENTION: the maximum values that can be set in
parameter AP01 are limited in order to never exceed
the maximum allowable pressure of the product.
8.4. First starting
OFF
ATTENTION: never run the pump dry. Start the
pump after filling it completely with liquid.
When the pump is located above the water level
(suction lift operation par. 14 fig. 2) or with a positive
suction head which is too low (less than 1 m) to open
the non-return valve, fill the pump through the priming
hole (par. 14 fig. 4).
ATTENTION: the pump is equipped with a integrated
non-return valve into the pump suction, in order to
fill the suction pipe it is necessary to prepare a filling
system on the suction pipe (par.14 fig.4).
When the liquid level on the suction side is above
the pump (inflow under positive suction head par. 14
fig. 1), fill the pump by opening the suction gate valve
slowly and completely, keeping the delivery gate valve
open to release the air.
Before starting, check that the shaft turns by hand. For
this purpose use the screwdriver notch on the shaft
end on the ventilation side.
8.5. Self-priming (Only for E-MXA, E-NGX)
(Capability to clear the air in the suction pipe when
starting with the pump located above the water
level).
Conditions for self-priming:
• suction pipe with connections perfectly airtight and
properly immersed in the water to be lifted;
• allow 0,5 m minimum of straight vertical pipe above the
discharge port, before a non-return valve par. 14 fig. 4.
E-MXAM E-MXPM E-NGXM Rev3 - Operating Instructions
• pump casing completely filled with clean cold
water berfore starting.
The pump is not self-priming with liquids containing
oil, alcohol or foaming substances.
The integrated check valve prevents reverse siphoning
through the pump when the pump is stopped and
retains water in the pump for the next start.
ATTENTION: avoid a prolonged operation
with unprimed
delivery from the completely opened outlet.
If the pump does not prime in 5 minutes:
stop the motor, remove the priming plug
and add more water.
If necessary, repeat the priming operation after the
pump has been first emptied and then completely filled
with clean cold water.
8.6. Vessel pressure
Once the new re-start pressure is entered (parameter
UP02), the tank preloaded pressure must be changed
to 0,2 bar lower than re-start pressure (i.e. 2,9
bar re-start pressure, tanks to be preloaded at 2.7 bar).
8.7. Gate valve regulation
With the gate valve completely open or with an outlet
pressure lower than the minimum pressure shown on
the name-plate, the pump may be noisy. To reduce
noise regulate the delivery gate valve.
8.8. Abnormal operation
Never run the pump for more than five minutes
with a closed gate valve.
Prolonged operation without a change of water in the
pump causes dangerous increases of temperature and
pressure.
Prolunged operation with a closed delivery port
causes breakage or damage to parts of the pump.
When the water is overheated due to prolonged
operation with a closed port, stop the pump before
opening the gate valve.
Do not touch the fluid when its temperature is
higher than 60 °C.
Do not touch the pump when the surface
temperature is higher than 80 °C.
Wait until the water has cooled inside the pump before
starting again or opening the draining and filling plugs.
8.9. Switch off of the pump
ON
The appliance must be switch off every time
there are faults. (see troubleshooting).
The product is designed for a continuous duty, the
switch off is performed by disconnecting the power
supply by means the expected disconnecting devices.
(see paragraph "6.5 Electrical connection").

9. MAINTENANCE

Before any operations it's necessary to disconnect the
power supply.
If required ask to an electrician or to an expert
technician.
Every maintenance operations, cleaning or
reparation executed with the electrical system
under voltage, it could cause serious injuries
to people.
If the supply cord is damaged, it must be
replaced by the manufacturer, its service agent
or similarly qualified persons in order to avoid
a hazard.
