CONNECTION OF THE DISCHARGE PIPE
5)
In order to avoid leaks and obtain optimum performance, it is important to mount the
fittings using Teflon.
6) START-UP
- Unscrew the filler cap on the pump casing.
- Using a receptacle, fill the pump casing until overflowing occurs.(Do not throw
water on the electrical parts).
- Put the cap back in place and screw it sufficiently tight to prevent air intake.
- If the water level drops in the case, re-examine the suction pipe fitting and
proceed to again fill the casing.
- Turn off the discharge line valve of your installation.
- Ensure that there is no water on the electrical parts of the pump and that there is
no leakage.
- Connect the power plug to a 10/16A socket featuring an earthing pin.
- Activate the power supply switch.
- The pump starts working and cuts out automatically as soon as pressure in the
tank reaches 3 bars approx.
- Slowly open the discharge line valve. The pump begins to discharge without the
engine starting thanks to the water stored in the tank.
- 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
turn off the switch controlling the pump.
● When the pump is not to be used for an extended period, be sure to also turn
off the pump's power supply.
