Installation and Maintenance
- Shut the cold water valve; fit the connection kit (feed adapter) to the cold water line.
- Drill the worktop first with a 5 mm, then a 12 mm bit and mount the faucet.
- Place the membrane in its housing; cut the 1/4" tubing into three and connect the inlet, faucet and drain lines.
- Open the valve (plug in the adapter on pump models); wait 1 hour for the tank to fill.
- Drain the first tank through the faucet; once it refills, the unit is ready for use.
Do not connect the unit to hot water (above 40 °C). Pressure: below 3 bar use the pump model or a pump kit; above 7 bar fit a pressure reducer at the inlet. Replace the filters at least once a year; if unused for over a month, close the valve and empty the tank.
