MAINTENANCE

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
gers, as fingerprints reduce the UV intensity.
6. Install a new UV lamp. Carefully press the lamp down
until it clicks into place and no longer can be turned.
7. Connect the socket to the new lamp.
8. Refit the insulation.
9. Refit the top cover and switch on the current to the
water purifier using the safety switch in the central
electrical unit.
10. Start the water purifier with the ON/OFF button.
11. Flush the water purifier for 1 minute.
Return the old UV-lamp to your dealer as it contains
mercury, which is very harmful to the environment.

Disinfection

algae growth. The tank, hoses and water purifier must be disin-
fected regularly.

fier and switch on the current to the water purifier
