6. STARTING
New pumps may feature a small amount of oil (the food
kind), which does not present a source of health risk.
6.1. VERSION WITH FLOAT (MA-MS) (SEE FIGURE)
Plug into the power mains and/or turn on with the switch:
the motor-driven pump starts working. Once the pump
has sucked in enough water to reach the minimum level
(“OFF” level), regulated by the  oat, it will turn o auto-
matically.
The  oat’s working position is factory set so as to assure a
minimum immersion level in the “OFF” position.
NB: If the liquid is overly contaminated, the operation of the
magnetic-type  oat (MS versions) may be compromised,
meaning it needs to be cleaned on a regular basis.
Moreover, do not use in liquids polluted with iron dust or
magnetic material as this would compromise the operation
of the  oat.
6.2. VERSION WITHOUT FLOAT
Plug into the power mains and/or turn
on with the switch:
the motor-driven pump starts working. Once the pump has
sucked in enough water to reach the minimum level, unplug
from the power mains and/or turn o with the switch.

7. MAINTENANCE
To maintain the motor-driven pumps properly and ensure
their long service life, the  lter and/or suction port must
not be clogged and the impeller must be clean.
During maintenance work on the motor-driven pumps, dis-
connect the power supply.
