How to proceed:
• Switch off the filter pump.
• Unlock the rotor cover (bayonet lock to "Lock open").
• Remove the rotor cover with the quartz glass and, if installed, the cleaning rotor.
– Set the rotary valve to the dirt water outlet to eliminate any vacuum that may have built up
in the container.
• Clean the quartz glass.
If you are replacing the quartz glass:
– Undo the clamping screw and carefully pull off the quartz glass with a slight pivoting and
turning movement.
– Clean the O-ring and replace it if it is damaged.
– Grease the O-ring with a commercial grease.
– Pull the O-ring over the collar of the quartz glass. (Not over the glass itself to avoid grease
residue on the quartz glass.)
– Position the quartz glass on the rotor cover and tighten the clamping screw all the way,
otherwise it will not be possible to install the rotor cover.
• Check for profile wear on the cleaning rotor. (→ Replacing the cleaning rotor)
• When installing the quartz glass, tighten the rotor cover all the way (bayonet lock to "lock
closed"). Otherwise it will not be possible to install the UVC unit head.
Condensate may form in the quartz glass. This condensate formation cannot be avoided,
however, it does not impair function and safety.
