Replacing a defective UVC lamp
• Ensure that the identification and capacity data of the UVC lamps used correspond to the information on the unit type
plate. (→ Technical data)
Prerequisite: The device head is removed. (→ Removing the unit head)
How to proceed:
 M, N
1. Carefully pull the lamp holder from the UVC lamps.
2. Turn the locking ring counterclockwise as far as the stop.
– Rotational direction "Lock open" symbol.
3. Guide the retaining plate over the UVC lamps and remove.
4. Change the defective UVC lamp.
– How to determine which UVC lamp of the respective lamp pair is defective (L1a/L1b or L2a/L2b): Change one of
the two UVC lamps and assemble the unit. If the system message is still displayed, reinsert the UVC lamp and
change the other UVC lamp. If the system message is still displayed, both UVC lamps are defective.
5. Guide the retaining plate over the UVC lamps and push it onto the locking ring.
6. Turn the locking ring clockwise as far as the stop.
– Rotational direction "Lock closed" symbol.
– The locking device fixes the retaining plate such that the UVC lamps are firmly seated in the lamp sockets.
7. Carefully press the lamp holder onto the UVC lamps such that all lamp heads engage.
Cleaning the quartz glass
C A U T I O N
Quartz glass and UVC lamp can break and cause cut injuries.
• Handle the quartz glass and UVC lamp with care.
N O T E
If the water flow is suddenly interrupted downstream of the outlet (e.g. with a slide valve), this can lead to a
brief increase of pressure of more than 1 bar (water hammer). Possible consequences: The unit may be da-
maged.
• Switching off: First switch off the pump, then close the slide valve. If the unit is operated in a filter system,
first take the filter system out of operation.
• Switching on: First open the slide valve, then switch on the pump. If the unit is operated in a filter system,
start up the filter system last.
• Install the slide valve upstream of the inlet.
Prerequisite: The device head is removed. (→ Removing the unit head)
How to proceed:

1. Turn the casing cover counterclockwise as far as the stop.
– Rotational direction symbol "Open lock".
– The casing cover can be very firmly seated. If necessary, insert a rod through the lugs to achieve greater lever-
age.
2. Carefully pull the quartz glass and cleaning rotor out of the casing.
3. Clean the quartz glass and the cleaning rotor.
– Pull off the cleaning rotor and clean with a brush under running water.
– Wipe the quartz glass with a damp cloth.
– Thoroughly clean the inner and outer surfaces of the casing.
4. Replace the quartz glass if it is damaged or very scratched.
– Undo the clamping screw and pull the quartz glass, together with the O ring, from the casing cover.
– Clean the O ring and lubricate with OASE grease (order No. 27872). Replace the O ring if it is damaged.
5. Fit the quartz glass together with the O ring onto the casing cover and screw in the clamping screw as far as the
stop.
– Pull the O ring over the flanged rim to avoid grease residue coming into contact with the quartz glass.
– Ensure that the clamping screw audibly engages, otherwise the casing cover cannot be fitted into the casing.
6. Check the profile wear at both ends and the inner surfaces on the cleaning rotor.
– If the profile is worn, the cleaning rotor rotates sluggishly and has to be replaced.
7. Push the cleaning rotor onto the quartz glass.
– Ensure that it is correctly positioned.
