c) Operation

• Open the water spray or the water tap on the pressure side. This is used to let the air escape from the
pressure switch and the garden hose.
• Connect the mains plug of the pressure switch to a protective ground mains socket.
• The pressure switch now activates the garden pump.
After water is conveyed, close the water tap on the pressure side. The garden pump keeps on running
until a specific operating pressure pre-set in the pressure switch is reached.
• If the pressure switch finds no flow, it will switch off the garden pump automatically. This is used to
protect from running dry. In this case, the LED „ALARM" lights up.
In this case, check if the suction hose connected to the garden pump is placed correctly, if any shut-off
valve in the suction hose has accidentally been closed or if a filter is clogged.
To support the suction process of a garden pump, it is helpful to fill the suction hose with water.
For this, a backflow stop must be installed at the end of the suction hose! If required, observe the
operating instructions for your garden pump.
• If no lair is in the hose system anymore, opening of the water spray or water tap (at the end of the garden
hose connected to the pressure switch) will cause the water pressure to drop. The pressure switch will
recognise this and automatically activate the garden pump while the water spray or water tap is open.
• After closing the water spray or water tap, the pressure in the garden hose will rise, upon which the
pressure switch will switch off the garden pump after a few seconds.
