Changing the cleaning rotor
The cleaning rotor has to be replaced when the racing surface is worn down to the wear marking ridges.
Adhere to the safety information given above! Press the safety engagement lever, turn the unit head (G) in the direc-
tion of the arrow up to the stop and carefully pull out including the cleaning rotor. Remove and replace the cleaning
rotor from the quartz glass. Re-assemble in the reverse order, in the same manner described under changing the UVC

Maintenance and cleaning
Attention! Dangerous electrical voltage.
Possible consequences: Death or severe injury.
Protective measures:
− Prior to reaching into the water, disconnect the power supply to all units used in the water.
− Disconnect the power plug prior to carrying out work on the unit.
Automatic cleaning
The cleaning rotor is continuously guided through the water flow around the quartz glass tube. The unit must run
permanently. Operation in intervals could lead to stubborn soiling and furring which have to be removed by manual
cleaning.
Cleaning the quartz glass tube (G)
Adhere to the safety information given above! Press the safety engagement lever, turn the unit head in the direction of
the arrow up to the stop and carefully pull out including the cleaning rotor. Remove the cleaning rotor from the quartz

using a moist cloth, and slide the cleaning rotor onto the quartz glass. Re-assemble in the reverse order, in the same
manner described under changing the UVC lamp. Start up the pump first, then connect the power supply.
Cleaning the inspection glass (J)
Adhere to the safety information given above! Press the safety engagement lever, turn the unit head in the direction of
the arrow up to the stop and carefully pull out including the cleaning rotor. Clean the inspection glass inner and outer
