PRECAUTIONS
1.
The intake strainer must always be in place during pump operation.
2.
The pump should not be started more than 20 times in one hour so as not to subject the motor to
excessive thermal shock.
3.
DANGER OF FROST:
When the pump remains inactive for a long time at temperatures of less
than 0°C, it is necessary to ensure that there is no water residue which could freeze and cause
cracking of the pump components.
4.
If the pump has been used with substances which tend to form a deposit, rinse it after use with a
powerful jet of water so as to avoid the formation of deposits or scale which would tend to
reduce the yield of the pump.
MAINTENANCE AND CLEANING
In normal operation, the pump does not require any specific maintenance, thanks to its
mechanical seal lubricated in an oil chamber and to its sealed-for-life bearings.
The
electropump must not be dismantled unless by skilled personnel in possession of
the qualifications required by the regulations in force.
In any case, all repairs and
maintenance jobs must be carried out only after having disconnected the pump from the
power mains.
During disassembly, pay attention to any sharp parts which could cause injury.
