Flotec EVO-MULTIMAX 340 LOGIC SAFE Manual De Instrucciones página 22

ENGLISH
power supply cannot be restored inadver-
tently.
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 period-
ically check the pressure delivered
and current absorption. A reduction
in pressure is symptomatic of pump
wear. An increase in current absorp-
tion is symptomatic of abnormal
mechanical friction in the pump.
• 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.
QUICK TROUBLE-
SHOOTING GUIDE
Refer to the "safety instructions".
The pump does not work
• No power supply = turn on the switch
and check that no electrical connec-
tions are loose or defective.
• Check the mains voltage
• Fuse blown = check that the cables
and relative connections are not de-
fective and replace the fuse if neces-
sary
• The single phase motor thermal cu-
tout has tripped = this is reset auto-
matically once the motor has cooled
22 22
• Motor overload cutout has tripped
= check that the cables and relative
connections are not defective, check
that the pump is not blocked mecha-
nically, or whether the pump winding
is damaged (replace if necessary)
• Electrical power line damaged =
replace
• Pump blocked mechanically = clean
• LOGIC-SAFE enabled.
The pump stops after a short interval of
operation due to a tripped motor pro-
tection device
• Excessive current absorption = check
the operating condition of the pump
• If foreign bodies are present, blocking
hydraulics = clean the hydraulic com-
ponents
• Phase missing on power supply (three
phase motor) = check the electrical
power supply
• The single phase motor thermal cu-
tout has tripped = this is reset auto-
matically 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
• Power cable damaged = replace
component
• Motor damaged = replace component
• LOGIC-SAFE enabled.
The pump starts up but does not deliver
liquid
• Pump is not primed = repeat the
"pump priming" procedure
• The pump takes in air = check the
liquid level, operation of the foot valve
and the suction pipeline
• The foot valve is blocked in the closed
position = replace or clean the valve
