10.1.3.
Inspecting the quartz immersion tube
Heat from the emitters and reactions from water constituents can cause deposition to
occur on the surface of the quartz glass. These deposits mostly consists of mineral
particles, biofilms and other residues generated by algae and bacteria. The deposits
cause the surface of the glass to cloud over, meaning that the required dose of UV light
can no longer penetrate into the water. The quartz tube must therefore be regularly
inspected and cleaned as necessary. With normal water quality, inspection of the quartz
immersion tube for deposits should ideally be carried out at six-month intervals. Note,
however, that relevant data is also transmitted continuously by the UV monitoring
system.
10.1.4. Cleaning quartz protective liner
After 8,000 hours of operation or with UV
lamp replacement
1. operation as lamp replacement Pos. 1 - 5
2. screw with a suitable tool solve
Be careful when removing -
Spring pressure on quartz immersion tube
3. Remove the quartz immersion tube carefully
4. Assemble in reverse order.
Caution
The quartz tube must be mounted centrally. Light pressure must be applied. If
in doubt, please repeat the procedure.
