Replacing UV lamp
The UV lamp needs to be replaced when the alarm lamp lights up on the control panel. First check whether the water purifier needs to be descaled instead.
Use only a genuine UV lamp from your dealer, to ensure that microbiologically safe water is supplied from the water purifier. See section “Consumable parts”.
1 Disconnect the water purifier by pressing the ON/OFF button.
2.Disconnect the power supply to the water purifier with the safety switch in the central electrical unit.
3.Remove top cover.
4.Remove the insulation above the UV lamp. Remove the socket from the lamp by pulling it straight up, see fig. H
5.Pull out the lamp, see fig. I.
Do not touch the new lamp glass with your fin- gers, as fingerprints reduce the UV intensity.
