Insert the tube with the rubber ring in the

7.0.4 Replacing the filter

Note:

Switch off the pure water dispenser before you

replace the filter.

The filter has a capacity of up to 3000 litres.

When 00 litres have passed through the

filter, the filter indicator c starts flashing to indicate

that you need to replace the filter. At this point,

the appliance can still dispense another 300 litres

of water, giving you time to arrange a new filter.

The filter indicator keeps flashing until 3000 litres

have passed through the filter. Then the filter

indicator lights up red continuously and the pure

water dispenser does not dispense water until you

replace the filter.

Note:

We advise you to change the filter every

6 months, even though you might not have

consumed 3000 litres. Filter life is subject to the

actual level of impurities in your water supply.

The filter may therefore expire before 3000

litres without any warning period.

Switch off the pure water dispenser.

7.0.3 Cleaning the quartz tube

We advise you to clean the quartz tube once

every months.

Warning:

Handle the quartz tube with care, as it might

break and cause injury. Do not tamper with the

quartz tube (apply glue, etc.).

Switch off the pure water dispenser.

Open the cover of the UV chamber.

To remove the UV lamp unit, follow steps 1

to 5 in section ‘Replacing the UV lamp unit’.

Pull out the quartz tube with the rubber

ring.

Remove the rubber ring.

Clean the quartz tube with a clean moist

cloth and dry it completely.

Reinsert the rubber ring to a depth of 2-

3mm from the open end.
