D

Switch the pump on first, then switch on the UVC clarifying unit.
– The UVC clarifying unit is designed to be operated with water passing through it. Never operate the unit without
water.

Switching on: Insert the power plug into the socket.
– The unit switches on immediately.
– The control lamp is lit.

Check all connections for leaks.

Switching off: Disconnect the power plug.
Note!

Following installation it takes several weeks for the bacteria to become established and for the filter to
become fully effective.

Increased bacterial activity starts at a water temperature of approx. + 10 °C.

A temperature monitor switches the UVC lamp off automatically if it overheats and on again once it has
cooled down.
Note!
The installed temperature monitor automatically turns the UVC clarifying lamp off, if it is overheated. The UVC
lamp will automatically switch on again once cooled down
