Philips WP3821 User Manual

When the battery is properly inserted, the LCD display performs a 

self-check for approx. 9 seconds. Then the display goes off again.
Before installation

The screw thread of the tap is sharp. 

Before you install the water purifier, make sure all tap-mounting 

adapters you require are present. 

The tap must have a diameter of 13mm-25mm.

Determine what type of tap you have and select the appropriate 

adapter.

The adapters supplied make the water purifier suitable for almost 

any kitchen tap. However, the water purifier may not fit some 

uncommon types of taps.

The tap water pressure has to be between 0.7kgf/cm² (7 metres of 

water column) and 3.5kgf/cm² (35 metres of water column). If you 

use the water purifier at a water pressure outside this range, either 

the filtered water flow will be extremely low or the water purifier 

will get damaged.

purifier housing (Fig. 7).

diameter of your tap (Fig. 9).

housing (Fig. 10).
