MAINTENANCE

DANGER - ELECTRIC SHOCK RISK
Before any intervention on the system, disconnect the electrical mains. Ensure that the electrical power
supply cannot be restored inadvertently
DANGER
Refer to the "safety instructions"
• In normal conditions, the electric
pumps do not require any
scheduled maintenance
• With a view to prevention
of possible faults, it is
recommended to periodically
check the pressure delivered and
current absorption

QUICK TROUBLESHOOTING GUIDE

DANGER
Refer to the "safety instructions".
WATER LEAKS FROM THE AIR VALVE OF THE EXPANSION TANK WHEN CHECKING THE GAS PRESSURE
The membrane inside the tank is damaged = replace the internal membrane of the tank or replace the tank itself
THE PUMP DOES NOT WORK
• No power supply = turn on
the switch and check that no
electrical connections are loose
or defective
• Check the mains voltage
• Fuse blown = check that the
cables and relative connections
are not defective and replace the
fuse if necessary
THE PUMP STOPS AFTER A SHORT INTERVAL OF OPERATION DUE TO A TRIPPED MOTOR PROTECTION DEVICE
• Excessive current absorption =
check the operating condition of
the pump
• If foreign bodies are present,
blocking hydraulics = clean the
hydraulic components
• Phase missing on power supply
(three phase motor) = check the
electrical power supply
26
• A reduction in pressure is
symptomatic of pump wear
• An increase in current absorption
is symptomatic of abnormal
mechanical friction in the pump
• Special maintenance may be
required to clean the pump and
replace any worn parts
• The single phase motor thermal
cutout has tripped = this is reset
automatically once the motor
has cooled
• Motor overload cutout has
tripped = check that the cables
and relative connections are not
defective, check that the pump
is not blocked mechanically, or
• The single phase motor thermal
cutout has tripped = this is reset
automatically once the motor
has cooled; check installation
conditions
• Thermal cutout protection
setting or fuses not suitable =
check protection devices with
respect to rated current of pump
• If the pump is not used for
prolonged periods (e.g. for
an entire season) it should be
drained completely rinsed with
clean water and stored in a dry
location
whether the pump winding is
damaged (replace if necessary)
• Electrical power line damaged =
replace
• Pump blocked mechanically =
clean
• LOGIC-SAFE enabled
• Power cable damaged = replace
component
• Motor damaged = replace
component
• LOGIC-SAFE enabled
