E-MXAM E-MXPM Rev1 - Operating Instructions
9.1. Routine maintenance
OFF
Before every maintenance operations
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
(par. 14 fig. 5).
Before restarting the unit, check that the shaft is not
jammed and fill the pump casing completely with liquid.
9.2. Vessel maintenance
Inspect the tank preloaded pressure of the delivery
vessel periodically.
9.3. Dismantling the system
Close the suction and delivery gate valves and drain
the pump casing before dismantling the pump.
9.4. Dismantling the pump
OFF
Close the suction and delivery gate valves and drain
the pump casing before dismantling the pump (par. 14
fig. 5).
10. DISPOSAL
OFF
European Directive
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

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.
Changes reserved.
