CHAPTER 6

MAINTENANCE

DANGER - ELECTRIC SHOCK RISK
Before any intervention on the pump, 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. A
reduction in pressure is symptomatic
of pump wear. An increase in current
absorption is symptomatic of abnormal
mechanical friction in the pump.

QUICK TROUBLESHOOTING GUIDE

DANGER
Refer to the "safety instructions".
7.1 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 single phase motor thermal cutout
has tripped this is reset automatically
once the motor has cooled
7.2 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
• Special maintenance may be required
to clean the pump and replace any
worn parts.
• 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.
• Motor overload cutout has tripped
check that the cables and relative
connections are not defective,
check that the pump is not blocked
mechanically, or whether the pump
winding is damaged (replace if
necessary)
• 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
INSTRUCTION MANUAL
• If the pump is used for applications
with drinking water for human
consumption and it is not used for a
long period, repeat the procedures
listed in Installation chapter.
• Electrical power line damaged =
replace
• Pump blocked mechanically = clean
• Power cable damaged = replace
component
• Motor damaged = replace component
