-
When the pressure in the tank falls below 1.5 bars approx., the pump starts up and continues working as
long as the pressure in the tank does not reach 3 bars approx.
-
To stop the pump cycles, slowly close the discharge line valve.
-
Always follow these instructions in order to prevent overpressure in the circuit, thereby avoiding
pressure fluctuations (“hammering”).
IMPORTANT!
● Do not operate the pump without there being water in the pump casing:
prolonged operation of the pump while the discharge line valve is closed may seriously damage the
pump.
● Where there is a power failure, it is preferable to disconnect the power plug or switch off the switch
controlling the pump.
● Where the pump is not used for an extended period, be sure to also turn off the pump’s power
supply.

MAINTENANCE
- In winter, the pump must be carefully emptied or positioned where it cannot be affected by frost.
- Before each new start-up, check that the gaskets are in good condition and that the fitting are airtight.
- For all repair or maintenance work requiring dismantling of electrical parts, you must contact an approved
after-sales service agent (see the dealer).
