Philips WP3820 - Manual (Page 12)

Screw the attachment nut firmly onto the water purifier
housing (Fig. 22).
Make sure the rubber washer is firmly pushed against the tap to prevent
water leakage.
Installing the filter cartridge
1 Make sure the tap is closed.
Set the water selection lever to the unfiltered stream
position (Fig. 23).
Tilt the filter cartridge 90° backwards and insert it into the water
purifier housing. (Fig. 24)
Pull the cartridge upwards until it is in upright position. (Fig. 25)
5 Air trapped inside the filter cartridge affects the flow rate of the
filtered water. To avoid this, slightly open the tap and let water run
through the filter cartridge for 30 seconds after you install/replace
the filter cartridge. The slow stream of water helps to remove any
air trapped in the filter.
