Cleaning/replacing the quartz glass
Prerequisite:
• The unit head is removed. (→ Removing/fitting the unit head)
How to proceed:
1. Wipe the quartz glass tube with a damp cloth
2. Check the O-ring on the unit head for damage and replace, if necessary.
3. On completion of the work, fit the unit head. (→ Removing/fitting the unit head)
Exchange the UVC lamp
Replace the UVC lamp after max. 8,000 operating hours. This ensures optimum filtering perfor-
mance.
• Bitron Premium 120 W / 180 W: Replace all UVC lamps.
WARNING
Touching current carrying cables can lead to death or severe injuries.
Disconnect the power plug before carrying out any work on the unit.
NOTE
Condensate may form in the quartz glass tube. This condensate cannot be avoided, however,
it does not impair function and safety.
The quartz glass tube can become scratched or blind over time. In this case, sufficient cleaning
performance of the UVC lamp is no longer guaranteed. The quartz glass tube must be re-
placed.
Prerequisite:
• The unit head is removed. (→ Removing/fitting the unit head)
How to proceed:
1. Using a screwdriver, loosen the safety screw securing the union nut on the quartz glass.
2. Unscrew the union nut by turning it counter-clockwise and carefully remove the quartz glass
using a slight twisting movement.
– Heavy impacts can damage the quartz glass or the UVC lamp underneath.
3. Carefully remove the lamp protection from the UVC lamp, then remove the shielding plate
from the base and finally pull the UVC lamp out of the base. Replace with a new UVC lamp.
– Only use UVC lamps that correspond with the device's technical data. (→ Unit data)
– After replacing the lamp, reinstall the shielding plate and the lamp protection at their re-
spective positions.
4. Carefully slide the quartz glass with the union nut and the O-ring onto the UVC lamp.
– Ensure that the O-ring is located between the union nut and the thread on the UVC clarifier,
in order that the quartz glass closes watertight.
5. Tighten the union nut in the clockwise direction as tightly as possible. Then tighten the safety
screw on the union nut.
