INSTALLATION AND USE
PRESFLO MULTI is an electronic device designed to control and protect single-phase domestic pumps with a power capacity of up to 2 HP. It is ideal for water supply and pressure boosting in residential settings, as well as for small-scale irrigation applications.
PRODUCT DESCRIPTION
※ PRESFLO MULTI features a pressure sensor and a flow sensor linked to an
electronic system that automatically activates the pump when a faucet’s
opening lowers the pressure below a specified level and deactivates it when
the flow stops or dips under 2 l/min.
※ PRESFLO MULTI is also equipped with:
- Pressure Gauge
- integrated 1-litre expansion tank useful in case of leaks and to protect against water hammer;
- option to adjust the restart pressure from 1 bar to 5 bar;
- capability to set the maximum current up to 16 A
The integrated electronics protect the pump from:
※ dry running
※ frequent start-ups due to leaks in the system;
※ Overcurrent
