TOP MULTI-TECH / TOP MULTI-EVOTECH
IlThis manual covers only the operation aspects of the TOP MULTI-TECH pump;
for safety instructions and further information please refer to the full instruc-
tion manual supplied.
GENERAL INFORMATION
The TOP MULTI-TECH / TOP MULTI-EVOTECH is a submersible multi-stage electric water-
pump with automatic operation, suitable for use in clear water without any suspended parti-
cles and at a max liquid temp of 40 °C.
The pump operates (stop/start) automatically on demand, controlled by an internal electronic
circuit and a valve on the delivery outlet.
The electronic system protects the pump dry running and seizure due to long periods of in-
activity.
OPERATION
On initial connection, the pump will run automatically for about 10 seconds to evaluate the
system even if the outlet taps are closed and will continue to run if taps are open. When the
taps are closed or the demand for water is less than 3 litres/min, the pump will stop after a
delay of approximately 10 seconds.
After the initial connection, the pump will start whenever the opening of a tap allows the
system pressure to drop below 1.5 bar.
Please note that the start and stop pressure is not adjustable.
The maximum vertical distance between the pump and the highest outlet point (tap) is 10 m.
Exceeding this limit will prevent the system from operating correctly.
☛
For optimum performance it is recommended that an expansion vessel of 3 li-
tres minimum is installed between the pump and the first outlet and its pressu-
re set to 1.2 bar.
Exceeding this limit will prevent the system from operating correctly.
Do not install a non-return valve on the pipes.
Exceeding this limit will prevent the system from operating correctly.
