Replacement UV Lamp for Watts WUV6-230

This is the replacement UV water filter lamp (Philips GPH436T5L/4 for Watts PWUVBULB6) for the Watts UV disinfection system WUV6-230.

Lamps are easy to replace and are rated for a 12 months (9,000 hours*) continuous service life. You must change your lamp every 12 months as risk of the lamp not working effectively after this time is HIGH and your water may not be safe. You must also have a pre-filter installed with a minimum of 5 micron filtration and the reason for this is that any sediment in your water will coat the inside of the UV systems quartz sleeve making the UV ineffective and your water unsafe.

You can purchase this with a quartz sleeve. Please see product options. Alternatively, if it's just a sleeve that you're after you can purchase these separately.

Maintenance

To get the best out of your UV system we recommend the following:

• Replace your lamp every 8,000-9,000 hours of operation (approximately 12 months of continuous service).

UV lamps and quartz sleeves are delicate and therefore easily damaged. So, be really careful when you're removing and replacing them.
