Start-up
Attention! Dangerous electrical voltage.
Possible consequences: Death or severe injury.
Protective measures:
• Electrical units and installations with a rated voltage of U > 12 V AC or U >30 V DC located in the water:
Isolate the units and installations (switch off and disconnect from the power supply) before reaching into the
water.
• Isolate the unit before starting any work.
• Secure the unit to prevent unintentional switching on.
Attention! Never operate the unit with a water pressure of more than 0.2 bar!
C
Important:
• Switch the pump on first, then the UVC clarifying unit.
• Do not operate the unit without water flowing through.
• The unit switches on automatically when power connection is established.
Switching on: Connect power plug to the socket.
• The control lamp is lit.
Note:
• After a new installation, the unit only reaches its full biological cleaning effect after a few weeks.
• The full effect on bacteria is only reached as from a water temperature of + 10 °C.
• In the event of overheating, the installed temperature monitor switches the UVC lamp off automatically, the lamp
automatically switches on again once cooled down.
Check all connections for leaks.
Switching off: Disconnect the power plug.
Maintenance and cleaning
Attention! Dangerous electrical voltage.
Possible consequences: Death or severe injury.
Protective measures:
• Electrical units and installations with a rated voltage of U > 12 V AC or U >30 V DC located in the water:
Isolate the units and installations (switch off and disconnect from the power supply) before reaching into the
water.
• Isolate the unit before starting any work.
• Secure the unit to prevent unintentional switching on.
Note:
• Check and clean the water outlet into the pond at regular intervals.
• Clean the filters at regular intervals (e.g. every four weeks), however, at the latest when cloudy or dirty water from
the water outlet returns to the garden pond.
• Carry out quick cleaning first. Should this prove insufficient, clean the entire unit.
• A blocked filter could lead to leakages.
• Never use chemical cleaning agents.
Quick cleaning
D
• Switch off the filter pump.
• Remove hose from the filter outlet by turning off the union nut (1).
• Remove hose from the filter inlet by turning off the union nut and screw on the filter outlet (2).
• Screw a dirt drain hose with stepped hose adapter on the filter inlet.
• Switch on the filter pump.
• Vigorously pull on the cleaning handle and „pump“ several times (3). In this manner, the foam filters are mechani-
cally cleaned until the draining water is clear.
• Switch off the filter pump.
• Remove the dirt drain hose and correctly reconnect the hoses for normal operation (Figure A).
Full cleaning
E
• Disconnect all hoses by turning off the union nuts (1).
