If the pump is unused for a long time it's advisable to
completely empty the pump, wash the hydraulic part with
clean water and stock it in a dry place. To start up again the
pump repeat the operation mentioned in this manual.

8. PUMP STORAGE

− Do not use the pump during cold winter weather. Frost
would certainly damage the pump.
− Unplug the pump. Dry it from residual water and store it
in a dry and frost-free place.
− To dry the pump just remove the plug places in the
lower part of the pump housing.
When the pump returns to service all rules described in this
leaflet must be repeated.
9. FOR PUMPS EQUIPPED WITH PRESSURE
TANK
If pump is equipped with pressure tank please check
periodically tank air pressure. For this operation remove the
plastic plug from one side of the tank and if necessary
inflate the tank to 1,4 bar (Fig. 3)
10. TROUBLESHOOTING
Motor does not start
(?) Mains voltage missing
Check the power cable, proper plug connection and
mains fuse efficiency
(?) Motor protector tripped for overheating
Remove cause for overheating (pumped liquid too hot?
Impeller blocked by foreign objects? Wrong voltage?).
After cooling the pump will return to operate
automatically
Motor hums but does not run.
(?) Impeller blocked by foreign objects
Check the free rotation acting with a screwdriver into
the groove of the fan side motor shaft (Fig. 1)
Pump works but water delivery is poor
(?) Required head is too high compare the pump
performance
Check characteristics in data plate and reduce distance
from pump and taps (in height) if necessary.
(?) Pipe bended, too small in size or clogged
Straight pipe, use larger piping or remove objects
clogging
(?) Pipes leak
Check connections .
Pump does not deliver any water
(?) Possible prime difficulties
Check actual well depth (remember that it should be not
lower than 9 metres at sea level, on hills this depth has
to be reduced)
Check leaks along suction piping
Pump starts/stops continuously (for pumps with tank)
(?) Tank air chamber is flat or too overinflated
Check air tank pressure (fig. 3)
