Installation
1. Install the three-way connector (1) and the ball valve (2) prior to the water tap.
2. In order to install the UF membrane (7), unscrew the lid cover of the UF filter housing (6), insert
the UF membrane (7) and then screw the lid back on again.
3. Mount the swan neck water tap (10)in the required position and connect it to the outlet of the
PI activated carbon filter “Gourmet” (9) with a PE connection tube.
4. The PE connection tubes are to be installed in the places A, B, and C.
5. Rinsing the system: After having installed the ball valve (2) and the swan neck water tap (10),
open the tap and let the water flow for 2 min.
Operation
•The system should be rinsed daily, by opening the purge valve (8) for 2 min.
•Before using the system for the first time, it should be prepared by opening the purge valve (8)
for 2 min and leaving at least ½ ℓof water flow through the swan neck water tap (10). After
having done so, the unit will provide clean water.
•After the last daily use of the filter unit, the ball valve (2) should be closed to protect the system
against pressure shocks.
