Several LEDs inform about the condition of the pres-
sure 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 associa-
ted connectors. Ensure that you do not swap input and
output of the pressure switch during assembly! Obser-
ve 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 pres-
sure switch. Use suitable connectors for this if requ-
ired.
• 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 connect
the garden pump to a „regular" mains socket!
c) Operation
• Open the water spray or the water tap on the pres-
sure 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 un-
til 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 gar-
den 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 pres-
sure in the garden hose will rise, upon which the pres-
sure switch will switch off the garden pump after a few
seconds.
8. Decommissioning
If the pressure switch is to be disconnected from the
garden hose and the garden pump (e.g. for cleaning,
maintenance or storage in winter), proceed as follows:
• Disconnect the pressure switch from the power sup-
ply, pull the mains plug from the mains socket.
• Then pull the mains plug of the garden pump from the
socket in the rear of the pressure switch.
• Open the water spray or the water tap at the end of
the garden hose connected to the pressure switch to
let the water pressure still present escape.
• Slowly remove the garden hose from the pressure
switch and then the pressure switch from the garden
pump.
• Empty the pressure switch (and your garden pump).
Dry the pressure switch and the mains cable. Keep the
pressure switch (and your garden pump) in a frost-pro-
of and dry room over winter. Also consider emptying
the hoses placed outdoors to prevent frost damage;
open any water taps that may be installed.
• After operation or emptying, a small amount of wa-
ter may remain in the pressure switch. Therefore, use
a suitable support when storing or transporting it in a
vehicle.
9. Maintenance and Cleaning
The pressure switch has no parts that require mainte-
nance by you. Therefore, never open or disassemble
it. Maintenance or repair and opening of the pressure
switch in this context must only be performed by a spe-
cialist or specialist workshop.
Before cleaning, disconnect the pressure switch from
the mains voltage; pull the mains plug from the mains
socket.
To clean the outside of the pressure switch, a dry, soft
and clean cloth is sufficient. Never use any aggressive
cleaning agents, cleaning alcohol or other chemical
solutions, since these may damage the casing or even
impair function.
10. Troubleshooting
With the pressure switch, you purchased a product
built to the state of the art and operationally safe. Ne-
vertheless, problems or errors may occur. Therefore,
observe the following information about troubleshoo-
ting.
The pressure switch activates the garden pump altho-
ugh no water is removed through the garden hose
• Check the hose system that is connected at the out-
put of the pressure switch for leaks.
Pressure switch reports running dry although there is
water in the hoses.
• The garden pump conveys no water. There may be
air in the garden pump, which will cause it to not suck
in any new water from the well.
• The water pressure is too high. Use a pressure re-
ducer between the garden pump and the pressure
switch. The maximum pressure for the pressure switch
is approx. 10 bar.
The garden pump does not switch off
• Check the hose system for leaks.
• To avoid too-frequent activation/deactivation of the
connected garden pump, the pressure switch delays
deactivation by a few seconds if a pressure increase
