(suction lift operation) fill the pump with water up to
suction port level through the opening on the strainer
after removing the cover (fig. 2).
Fig. 2 Filling
8.2.2. Self-priming
(Capability to clear the air in the suction pipe when
starting with the pump located above the water level
and when the suction pipe cannot be filled manually, as
in the case of a missing foot valve).
Conditions for self-priming:
• Pump casing filled with water up to suction port level
before starting.
• Suction and discharge valves completely opened and
pipes not obstructed.
• Strainer basket not obstructed.
• Suction pipe with connections perfectly airtight, and
properly immersed in the water to be lifted.
• O-ring on the strainer casing and mechanical seal
perfectly airtight (properly seated, clean and not
damaged).
• Hand wheels on strainer cover and thumbscrew
drain plug on strainer casing tightened to prevent air
entering.
• Discharge pipe without check valve, with minimum 80
cm straight vertical free pipe above discharge port.
Set the desired self-priming mode (see para. 7.5.1)
and make sure that all the conditions for self-priming
are met.
In case of error Er07 “Not primed” check all the above
conditions, restore them or remedy them where
necessary. Then to reset press the enter button
and the start button
to restart the pump.
ATTENTION: avoid prolonged operation
with the pump not primed, without water
delivery from the completely opened outlet.
If the pump does not prime in 5 minutes: stop the
motor, remove the filler cap 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.
8.3. SWITCH-OFF
ON
The appliance must be switched off every time
there are faults. (see troubleshooting).
The product is designed for continuous operation, the
switch off is performed by disconnecting the power
supply by means of the dedicated 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.
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.
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

the maintenance of the device, contact Calpeda S.p.A.
9.1. Routine maintenance
OFF
The motors with supply current directly switched
by thermally sensitive switches can start
automatically.
Disconnect electrical power before any
servicing operation and make sure the
pump cannot be accidentally switched on.
Inspect and clean the strainer basket periodically.
The frequency of cleaning depends on operation time of
the pump, pool environment, wind (for open air swimming
pools) and the number and behaviour of the bathers.
With the pump located below water level, close the
suction and delivery gate valves before removing the cover.
The strainer can be easily accessed by removing the
strainer cover (fig. 3).
