Product Description
The unit comprises the following components:
A
1 Level control unit for processing the measured values from the level sensor and controlling the solenoid valve
2 Solenoid valve for topping up the pond with drinking water
4 Level sensor for detecting the water level in the pond
Not included in the delivery scope but indispensable for the intended use:
3 Free flowing outlet (air gap separation) of the drinking water in a supply pipe to the pond
5 Pond overflow
The level control unit in conjunction with the level sensor functions as follows
The level control unit is permanently connected to the level sensor, the electrodes of which are immersed in the pond
to be monitored. The level control unit is also connected to the solenoid valve.
The level control unit generates a measuring signal which is used to monitor the voltage applied between the elec-
trodes of the level sensor. The level control unit opens or closes the solenoid valve depending on the measured value.
A switch-on and switch-off delay in the electronics prevents wave action from causing unnecessary switching.
The LEDs in the display of the level control unit signal the respective status of the drinking water top-up process.
The sensitivity of the level sensor to a voltage change can be adjusted via a sensitivity regulator in the level control
unit. The sensitivity is set in the factory such that changes are not normally required.
The level sensor is operated with a safe extra-low voltage of 12 V (not dangerous to humans) and may therefore be
used in swimming or bathing ponds.
The solenoid valve functions as follows
The solenoid valve converts the electrical signal from the level control unit into a mechanical opening or closing move-
ment. The solenoid valve is closed when there is no electric current.
Safety information
The unit has been built according to the state of the art and the current safety regulations. Despite the above, hazards
for persons and assets may emanate from this unit if it is used in an improper manner, not in accordance with its
intended use, or if the safety instructions are not adhered to.
For safety reasons, children and young persons under 16 years of age as well as persons who cannot recog-
nise possible danger or who are not familiar with these operating instructions, are not permitted to use the
unit. Keep children under supervision to ensure that they do not play with the unit.
Hazards encountered by the combination of water and electricity
− The combination of water and electricity can lead to death or severe injury from electrocution, if the unit is incorrectly
connected or misused.
Correct electrical installation
− Electrical installations must meet the national regulations and may only be carried out by a qualified electrician.
− A person is regarded as a qualified electrician, if, due to his/her vocational education, knowledge and experience, he
or she is capable of and authorised to judge and carry out the work commissioned to him/her. Working as a qualified
person also includes the recognition of possible hazards and the adherence to the pertinent regional and national
standards, rules and regulations.
− For your own safety, please consult a qualified electrician.
− The unit may only be connected when the electrical data of the unit and the power supply coincide. The unit data is
to be found on the unit type plate or on the packaging, or in this manual.
− Ensure that the unit is fused for a rated fault current of max. 30 mA by means of a fault current protection device.
− Install the level control unit and solenoid valve with a minimum safety distance of 2 m from the water.
− Install the level control unit and solenoid valve so that they are protected from the sun, rain and from temperatures
below zero.
