The present Manual contains basic instructions for
installation, operation and maintenance.
Please, read the present Manual carefully before the device
operation in order to avoid accidents and breakage.
CORRECT USE
The device is designed for automatic on and off control of
single-phase surface and submersible pumps (including
vibration pumps) with power of up to 1.5 kW according to
flow and minimum pressure (Pmin), and for pump dry-running
protection and other emergency situations.
The control unit maintains pressure thresholds Pmax and
Pmin in water supply system preset by pressure sensor in
(switches the pump on at Pmin and switches the pump off at
Pmax).
If for some reason the pump does not build up preset Pmax
in eth system (dry-running mode, los supply coltage and
other emergency situations), the pump is switched off with
30-second delay at flow rate less than 2 l/min.
