9. PRECAUTIONS

• RISK OF FROST: when the pump remains inactive at a tempe-
rature lower than 0°C, it is necessary to ensure that there is no
water residue which could freeze, causing cracks in the plastic
parts.
• If the pump has been used with substances that tend to form
a deposit, rinse it after use with a powerful jet of water in order
to avoid the formation of deposits or encrustations which would
reduce the characteristics of the pump.
• Ensure that the float switch does not touch the walls of the trap
during operation.
• Ensure that the OFF level is not too close to the suction grid,
minimum height below the filter 60/70mm.
