1. FEATURES
Is designed to automatize the starting and stopping operations of an electric
pump with regard to a drop in pressure (opening of the taps) and to the
stopping of the flow through the system (closing of the taps), respectively. It
stops the pump when senses the lack of water flow, preventing it from any
damaging dry operation.
It is advisable to use with water systems whose water is without sediments. In
case it is not possible, it is necessary to install a filter before the inlet of the
device.
The pressure gauge checks the starting pressure value and the pressure in
the system.
Furthermore it verifies any possible presence of water leakages in the very
system.
PLEASE READ THIS INSTRUCTION LEAFLET CAREFULLY THROUGH
BEFORE INSTALLING AND OPERATING THE DEVICE.
2. SAFETY REGULATIONS
To avoid shocks and fire risks, read and follow closely the
following instructions:
Always unplug the device from the mains before carrying out any
work on it.
Be sure that the electric line connecting the device to the mains
and the extension leads have a cross-section suitable for pump
power and be sure that the electrical connections are far away from
any water source.
When used for swimming pools, ponds and fountains it is
necessary to use an automatic RCD with IDn=30mA protection.
WARNING: when the pump stops the pipes are under pressure
consequently we recommend opening a tap to discharge the system
before carrying out any work.
