-> Status (run/stb/off) -> Pressure (bar) -> Power (kW)
-> Voltage (V) -> Temperature (°C) -> Current (A).
Now the pressures displayed are referred to the
pressure gauge height instead of the pump height.
ATTENTION: if the pump is always submerged with
water level not excessively variable, parameter AP01
can be used (pump suction pressure).
To prime the pump properly, at first start the minimum
immersion depth must be at least 1 meter.
An air vent valve must be used in systems with an
immersed delivery outlet (par. 14 fig. 3).
Do not start the pump with a completely closed shutoff
gate valve.
Never take the pump out of the water while the pump
is still operating.
8.5. 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).

8.6. Abnormal operation

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.
8.7. Switch off of the pump
ON
The appliance must be switch off every time
there are faults. (see troubleshooting).
The product is designed for continuous operation,
only by disconnetting the supply cable the switching
off occurs. (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.
In case of extraordinary maintenance, or maintenance
operations that require part-removing, the operator
must be a qualified technician able to read schemes
and drawings.
It is suggest to register all maintenance operation
executed.
E-MPSM Rev1 - Operating Instructions
During maintenance keep particular attention in
i
order to avoid the introduction of small external
parts, that could compromise the device safety.
It is forbidden to execute any operations with
the direct use of hands. Use water-resistant,
anti-cut gloves to disassemble and clean the
filter or in other particular cases.
During maintenance
i
personnel is not allowed.
Maintenance operations that are not described in
this manual must be made only by special personnel
authorized by Calpeda S.p.A.
For further technical information regarding the use or
the maintenance of the device, contact Calpeda S.p.A.

9.1. Routine maintenance

OFF
Before every
disconnect the power supply and make sure
that the device could not accidentally operate.
In the case of water containing chloride
(chlorine, sea water), the risk of corrosion
increases in stagnant water condictions (also
with an increase in temperature and decrease
of pH value). In these cases, if the pump
remains inactive for long periods, it must be
emptied completely and, preferably, dried.
For good measure, as in the case of temporary
operation with dirty liquids, run the pump
briefly with clean water to remove deposits.
When the pump remains inactive it must be
emptied completely if there is a risk of freezing.
Before restarting the unit, fill the pump casing
completely with liquid.
9.2. Vessel maintenance
Inspect the tank preloaded pressure of the delivery
vessel periodically.

10. DISPOSAL

European Directive
OFF
2012/19/EU (WEEE)
The final disposal of the device must be done by
specialized company.
Make sure the specialized company follows the
classification of the material parts for the separation.
Observe the local regulations and dispose the device
accordingly with the international rules for environment
protection.

11. SPARE PARTS

11.1. Spare-parts request
When ordering spare parts, please quote their
designation, position number in the cross section
drawing and rated data from the pump name plate
(type, date and serial number).
The spare parts request shall be sent to CALPEDA
S.p.A. by phone, fax, e-mail.
