To clean the grid
The grid ( a coarse filter) is conceived to intercept large particles; it’s located inside the union where you connect the
RO400C’s feed water hose. If the LEDs on the control panel show that the intake pressure is too low, the reason may be
that the grid is clogged.
1. Disconect the appliance from the electrical supply.
2. Unscrew the flexible feed water hose, on the back of the
appliance.
3. Use suitable pliers to grip and remove the grid (picture A).
4. Clean the grid. Then put it back inside the connector.
5. Reconnect the feed water hose to the appliance.
6. Connect the RO400C to the electrical supply.
The water purifier will flush automatically.
