Introduction
Thank you for choosing to purchase this quality product. To minimise the risk of injury, we ask you to
always take some basic safety precautions when using this product. Please read this operating manual
carefully and make sure that you understand it.
Keep these operation instructions in a safe place.
Safety instructions
•This device must neither be used by children nor individuals with reduced physical, sensory, or
mental capabilities, or lack of experience and knowledge, unless they have received instructions
concerning the use of the appliance from a person familiar with the product and responsible for
their safety and are supervised by the same. Children are not allowed to perform user
maintenance and should be supervised at all times in order to ensure that they do not play with
the device.
•Always check the device before using it. Do not use the device if components are damaged or
worn, and never disable safety devices for any reason.
•Be aware that you are responsible for the security of your working environment. Always make
sure to keep it clean and well-lit as cluttered and dark working environments increases the risk
of accidents.
•Be aware that extreme changes in temperature may lead to deviations of the shift point or even
to a complete failure of the pressure switch.
•Only use this product in its original condition and do not perform unauthorised modifications.
•Avoid additional mechanical stress originating from vibrations or surges.
•Always pay attention to the specified pressure range and avoid any kind of excess pressure.
Exceeding the maximum pressure may negatively influence the performance of the device and
even damage it.
•Never touch, lift, or move the compressor connected to the power supply by the cable. Make
sure that the connection socket is protected from water and moisture.
•Always disconnect electric devices from the power supply before maintenance and cleaning
work.
•No responsibility is accepted for damage to the device caused by improper use or incorrect
maintenance.
Intended use
Pressure switches are utilised in order to operate pumps, valves or compressors and serve the purpose
of regulating the pressure. When a device reaches the previously set maximum pressure level the pres-
sure switch is activated and disrupts the control circuit in order to turn the motor off. In case of the
pressure level being too low, the pressure switch activates the motor in order to build up additional
pressure. This pressure switch was designed to be attached to mini compressors with electric motors
with a power of up to 5.5 kW. Improper use or modification of this device can damage the it as well
as its surrounding area and can further lead to severe injuries for which the manufacturer cannot
be held responsible.

Operation
•Read the manual and make sure that the device is in pristine condition.
•Connect the pressure switch to the designated pressure port and the pressure relief valve to
the pipe.
•Connect the cables according to the circuit diagram below.
•Ensure that the pressure switch has been earthed correctly.
•If the rated pressure has to be adjusted, this can be done with the help the adjusting screw and
a screwdriver. Make thereby sure that the pressure is equal on both sides of the spring. Turn
the adjusting screw clockwise in order to decrease the pressure and counter-clockwise in order
to increase the same.
•Regularly check the connections and remove possible accumulations in order to guarantee a
correct mode of operation.
