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.
i
During maintenance keep particular attention in
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.
i
During maintenance operations external
personnel is not allowed.
Maintenance operations that are not described in
this manual must be made only by special personnel

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 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.
