Information about the device
Device description
In order to deliver service water for home and garden, the
pressure switch serves to control the pump.
The device is installed between a pump and one more
extraction points (e.g. a water tap or a garden sprayer). It
monitors the pressure in the water line. Should the pressure in
the water line drop below a predefined value, the device will
switch on the pump. To avoid the pressure dropping below the
value, the electrical supply of the pump has to be connected to
the pressure switch. The pressure switch recognises when the
pressure level is sufficient (e.g. because the water tap has been
closed), and switches the connected pump off.
The device also monitors the flow rate volume. Should the water
flow rate drop below a value of 1.2 l/m (e.g. because the pump
runs dry), the device switches off the connected pump.
The restart button on the pressure switch is used for restarting
the connected pump manually (e.g. when the device switches
the pump off because the pump is running dry).
In addition, the device is equipped with a backflow preventer.
The pressure switch must be connected at maximally 30 m
underneath the highest-level consumer.
The water temperature must not exceed 60 °C.
The device may be used in facilities with up to 10 bar water
pressure.
Moreover, the device is fitted with a pressure gauge.
