7. Assembly & Connection, Operation
a) Function Description
The pressure switch is installed at the output of a garden pump (pressure side) and the mains cable of the
garden pump is connected to the socket in the rear of the pressure switch.
After the pressure switch has been connected to the mains voltage, the pressure switch will activate the
garden pump for about 35 seconds.
If a certain working pressure set ex works is reached, the pressure switch will switch off the garden
pump.
When opening, e.g., a water spray or water tap on the outlet side of the pressure switch, the water pres-
sure drops, upon which the pressure switch automatically activates the garden pump. The garden pump
will run until the water spray or tap is closed. Then the water pressure in the garden hose increases, the
pressure switch switches off the garden pump again.
The pressure switch also monitors the flow rate. If no noticeable water flow is recognised, the pressure
switch switches off the connected garden pump automatically to protect it from running dry.
A „RESTART" button on the pressure switch serves manual restart of the pump (e.g. if the pressure switch
has recognised running dry).
Several LEDs inform about the condition of the pressure switch and its current function, see chapter 7.
b) Assembly & Connection
• First disconnect your garden pump from the mains voltage, then switch off the garden pump and pull the
mains plug from the mains socket.
• Open the water spray or water tap at the end of the garden hose of the pressure side of your garden
pump so that the remaining overpressure can escape.
• Remove the garden hose at the outlet (pressure side) of your garden pump.
• Install the pressure switch at the output (pressure side) of the garden pump.
For this, e.g. the enclosed threaded connection piece can be used, or, alternatively (depending on build
of the garden pump), a piece of hose with the associated connectors.
Ensure that you do not swap input and output of the pressure switch during assembly! Observe
the figure in chapter 7.
Never install the pressure switch on the suction side of the garden pump!
• Connect the garden hose to the output of the pressure switch. Use suitable connectors for this if requi-
red.
• Now connect the mains plug of the garden pump to the protective ground mains socket of the pressure
switch.
The power supply of the garden pump must take place via the pressure switch. No longer con-
nect the garden pump to a „regular" mains socket!
