STARTING
After that the pump is primed, it is possible to give current to the device. The
pump starts immediately and the green led (Power on) and the yellow led (Pump
on) will switch on. After 20 sec., if all the plant taps are closed, the pump and the
yellow led will be off, the pressure gauge will indicate the plant pressure and RE-
START & GO will control the plant. If during the normal working the water should
miss (absence of flow) RE-START & GO will stop the pump after 8 sec. For restore
the operating, prime the pump and press RESET.
POSSIBLE PROBLEMS
Pump doesn't stop:
-There is a leakage inside the plant, check all the taps, w.c., pipes.
- RESET button is blocked, press it for several times.
- The inner flow-switch is blocked by dirty, remove the device from the plant and
clean it.
- The electronic board is broken, remove the electronic board box and substitute
it with a new one.
- The pump doesn't start
- Water column is higher than 15m, increase start-up pressure.
- Red led is on, pump is not correctly primed, pump doesn't develop the mini-
mum pressure required (2,5 bar), inner membrane is broken (the device has a
leakage of water in its rear part), pump capacitor is broken, pump is blocked, elec-
tronic circuit is broken.
- Pump starts and stops continuously
- There is a little leakage into the plant, repair the leakage or install a pressure
tank.
- Request of flow lower than 1,5 l/min.
- Pump doesn't develop enough pressure.
