Hanovia 230 - Replacement UV lamp- 130035-0652-01 TOC Lamp

This is the genuine replacement UV lamp for the Hanovia 230 disinfection system, part number 130035-0652-01, specified for TOC (total organic carbon) applications. WrekinWater stocks it for customers whose lamp has reached the end of its service life or has failed outright. Fitting the correct lamp keeps the system's disinfection dose where it should be.

Signs you need this part

• The lamp fails to light, or flickers and won't stay on.
• The Hanovia 230 controller displays a lamp-fault or end-of-life warning.
• The lamp has reached the end of its rated service life, typically around 12 months of continuous running.
• You can see blackening or discolouration at either end of the lamp tube.

The UV lamp emits the germicidal UV-C light that inactivates bacteria and viruses as water passes through the chamber. Lamp output naturally fades with age well before the lamp actually goes out, so a lamp that's visibly lit can still be delivering a lower dose than the system needs. Running past the recommended replacement point risks disinfection falling below a safe level without any obvious sign until the lamp finally fails.

How to fit it

1. Turn off power to the UV system at the isolator and, where fitted, isolate the water supply.
2. Undo the retaining union or end cap on the UV chamber.
3. Carefully withdraw the old lamp from inside the quartz sleeve without touching the sleeve with bare hands.
4. Fit the new 130035-0652-01 lamp into the sleeve, seating the connector fully home.
5. Reassemble the union or cap and restore power to the system.
6. Reset the lamp-hours counter on the Hanovia 230 controller, if fitted.
