purifier to crack, discolor or distort. Do not clean any part of the water
purifier in a dishwasher.
Do not use a kitchen sponge or cloth to clean or dry the inside of
the water reservoir because they are likely to contain bacteria. To clean
the water reservoir in a hygienic way, follow the cleaning instructions
below.
You can remove the water reservoir for cleaning purposes without closing
the main valve. No leakage will occur thanks to a one-way valve that blocks
the water flow.
We advise you to drain the water reservoir before you remove it from the
water purifier. This makes the water reservoir easier to handle.
Cleaning the outside surface of the water purifier
- Clean the outside of the water purifier with a damp cloth and some
washing-up liquid.
- If necessary, you can also remove the front panel from the reservoir. To
release the front panel push down the tab on the reservoir (1), then
slide the panel from the reservoir (2). Clean the reverse side of the
front panel and the outside of the water reservoir with a soft sponge
and some washing-up liquid.
Clean the water reservoir tap and the connection between the reservoir
and the wall holder only with a properly disinfected sponge or cloth. See
'Hygiene awareness' in chapter 'Important'.
thorough cleaning of the water reservoir
Philips advises you to clean the inside of the water reservoir thoroughly on
a regular basis (once a month). To clean the water reservoir in a hygienic
and simple way, follow the instructions below.
- Make sure the reservoir has filled up to its maximum volume. Remove
the reservoir cover and add 30ml of household bleach in case of a 5%
solution of sodium hypochlorite, or 60ml in case of a 2.5% solution.
- Mix the bleach thoroughly through the water with a spoon. This
disinfects the inside of the water reservoir.
- After 1 minute, drain the reservoir and throw away the water.
- After the reservoir has filled up again to its maximum volume, check if
the water still has a chlorine taste.
- If it does, throw away the second full reservoir of water as well.

Filter holder

The filter holder does not require regular cleaning. Only clean it when you
replace the filter (see chapter 'Filter replacement').
Note: The filter itself does not require any cleaning.

Filter replacement

Do not open the main water valve if the filter holder is not in place.
Note: After the filter has purified 2000 liters of water, the Ultra Pure Protect
lock is activated. This lock closes off the flow of water through the filter and
as a consequence the water reservoir does NOT refill. When this happens, you
know it is time to replace the filter.
