manual or automatic cleaning of the pipework:

Manual cleaning using fresh water

hoses are purged and the sensors are cleaned using a sprayhead and clean water. The
control of the cleaning system is done by manually operating a ball valve. the pump
must be switched off when purging the suction hoses.

spay head and clean water. Control is provided by a small integrated

The cleaning sequence can also be started manually (pushbutton on the swing frame).
If the sensors are to be cleaned manually, then the pump must be switched on.
