Operating Instructions
Your Philips Water Ontap filter offers three modes of water flow:
- Filtered Water: Use this mode for drinking and cooking. The digital display will show the remaining filter capacity.
- Unfiltered Water (Stream): Use this for general washing where filtered water is not required.
- Unfiltered Water (Spray): Ideal for rinsing dishes or produce.
To switch between modes, rotate the selector lever on the side of the filter unit.
Digital Display
The digital display indicates the remaining filter life in liters. When the display approaches zero, it is time to replace the filter cartridge. A new filter cartridge typically provides 1000 liters of filtered water or lasts up to 6 months, whichever comes first.
