Ultraviolet Disinfection (UV) is a proven and safe method for water disinfection. UV produces the same result as chlorinated water. The difference is - Ultraviolet does not add chemicals, nor does it alter the taste, color, or odor of water. Only the highest quality UV systems are used in the H2O Bottleless Water Coolers. The Phillips bulbs operate at the most effective wavelength. You can rest assured that 99.9% of bacteria and viruses are eliminated, including cryptosporidium, Hepatitis-A, Poliovirus, Streptococcus, Adenovirus, E.Coli, Rotavirus, and Giardia. If your water source is from a rural water supply, or a well, consider adding UV. Ultraviolet will ensure that your water is safe and contaminant-free.
Replace the UV bulb annually.
How do I locate the UV bulb housing on the H2O unit?
Follow these steps to safely locate the UV bulb housing:
- Open the lower front door panel (where the filtration system is located).
- Remove the two screws on the rear upper-left and upper-right corners of the top panel.
- Carefully lift the top cover/lid.
- The UV bulb housing is seated on the cold-tank lid beneath the top cover.
You can then visually verify whether your bulb is:
- White
- Black
- LED V3
If replacing the bulb, always disconnect power before servicing. If you are unsure, contact a qualified technician.
