Two identical kitchen buckets with a showerhead and a blue prohibition symbol on a grid background (no text or labels)

Only connect this water purifier to wall-mounted cold water kitchen faucets or secondary water outlets. Do not connect this water purifier to sink-mounted faucets.

Make sure that there are no electric cables or water pipes inside the wall at the location where you want to mount the water purifier.

Make sure that there is no electric outlet under the water purifier.

Installation

1 Close the main water valve before you install the water purifier.
2 Determine the location where you want to mount the water purifier to the wall. This depends on the location of the water outlet and the available hose length.
3 Remove the drilling template from the box and use it to mark the points on the wall where to drill the holes.

- Make sure the two top holes are level.

- The recommended distance between the countertop and the lower mounting hole of the wall holder is 35cm. If you want to be able to fill high bottles, i.e. 1.5 or 2 liter soft drink or mineral water bottles, drill the lower hole at 50cm for your convenience. Also make sure that you leave a free space of at least 15cm above the upper two mounting holes of the wall holder when you place the water purifier under a kitchen cupboard or shelf.

4 Drill the holes with a 6mm drill and put the fixing plugs in the holes.

- The fixing plugs and screws are supplied with the water purifier

Note: In case of a wooden wall, skip this step.

Note: In case of a hollow wall, use special hollow wall fixing plugs (not supplied).

5 If the water outlet has 1/2" thread, screw the water supply connector onto the water outlet first. Then attach the adapter ring and finally screw the original kitchen faucet onto the adapter ring. Wind Teflon tape round all threaded parts to prevent leakage.

Note: If the water outlet is a secondary water outlet, screw the cap onto the open end of the adapter ring.

6 If the water outlet has 3/4" thread, screw the adapter ring onto the water outlet first. Then attach the water supply connector and finally screw the original kitchen faucet onto the water supply connector. Wind Teflon tape round all threaded parts to prevent leakage.

3 Place the filter holder with filter into the wall holder.

4 Push down the filter holder release lever to lock the filter holder into place ('click').

5 Place the water reservoir onto the wall holder (1). Put the cover on the water reservoir (2). To lock the cover, push the lock lever towards the wall (3). Make sure that the water reservoir tap is in closed position (turned all the way to the left or right).
6 Open the main water valve. Observe the water purifier for 5 minutes to check for any leakage between connections.
7 If leakage occurs, locate the connection that leaks. Turn off the main water valve. Loosen the connection that leaks and fasten it again in the proper manner. Reopen the main water valve. Check again. Repeat all steps in 'Installation' and 'Preparing for use', if necessary.
8 The water reservoir now automatically fills with purified water to its maximum volume of approximately 4 liters. An internal mechanism prevents the reservoir from overflowing.
9 After the reservoir has filled up to its maximum volume for the first time, remove the reservoir cover and add 30ml of household bleach (5% solution of sodium hypochlorite). If your household bleach contains a solution of only 2.5% sodium hypochlorite, you should use 60ml. 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.

The water purifier is now ready for use.

The water reservoir is only intended to contain purified water. Do not put ice or any other ingredients in the water reservoir.

Using the water purifier

If you have not used the water purifier for 2 days or more, drain the water reservoir completely and throw away the water. If necessary, clean the water reservoir. See chapter 'Cleaning and maintenance'.

Note: Keep the main water valve always open. This ensures that the pure water reservoir refills automatically. The filling speed of the water reservoir depends on the state of the filter and the quality and pressure of the input water.

Dispensing water

1 Put a glass under the water reservoir tap to collect purified water.

Note: Besides a glass, you can also use a jar or a properly cleaned used mineral or soft drink bottle.

• To increase the water flow, turn the tap lever to the front.
• To reduce the water flow, turn the tap lever to the left or right.

Cleaning and maintenance

Caution: Never use scouring pads, detergents, abrasive cleaning agents or aggressive fluids such as thinner, alcohol, petrol or acetone to clean the water purifier. These substances may cause the material of the water

ENGLISH42

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.

Note: If the Ultra Pure Protect lock has not been activated after 6 months of use, Philips advises you to replace the filter anyway. This prevents deterioration of the taste of the purified water due to diminished effectiveness of the activated carbon in the filter. The purified water is still pure, but a deteriorated taste can reduce your pure water experience. If there are many impurities in the water, the Ultra Pure Protect lock is activated before 2000 liters of water have been purified.

Note: Collect a few liters of water in a clean container before you replace the filter, as the main water valve is closed during the replacement procedure. You need this water to clean the filter holder.

1 Close the main water valve before you replace the filter.

2 Open the water reservoir tap and drain the water reservoir completely.

3 Pull out the lock lever (1), lift the cover (2) and remove the water reservoir from the wall holder.

4 Hold a cup under the spout to collect any water that may come out of the filter holder during decompression and press the decompression button. Keep the decompression button pressed until no water or air comes out of the spout anymore.

5 To open the filter holder release lever, press the decompression button with one hand (1) and pull the front part of the release lever towards you with your other hand (2).

6 Now you can lift the filter holder release lever.

Note: See figure 1 for a cross-sectional drawing (P) of the filter.

• This Philips water purifier uses filter cartridge type WP3970, which contains (1) a pre-filter, (2) Granular Activated Carbon (GAC), (3) Ultra Filtration (UF) membranes, and (4) a filter stop.
• The pre-filter removes big particles, e.g. sand.
• GAC is generally known to remove many kinds of unwanted dissolved chemicals such as chlorine, volatile organic compounds (VOCs),

chlorination by-products (CBPs), pesticides and medicine residues, and in this way improves the quality, taste, color and odor of the water.

- The UF membranes act like a sieve with extremely small pores (approximate size 10-15 nanometers) capable of removing all particles and microorganisms that are bigger in size. The triple gold seal certificate granted by the Water Quality Association (WQA) implies that this water purifier supplies you with microbiologically safe drinking water as tested according to the USEPA Microbiological Guide. More specifically this water purifier effectively removes at least 99.9999% of bacteria, 99.99% viruses and 99.9% of cysts.

- The filter cartridge has an integrated mechanism to count the amount of water that is purified by the filter, called Ultra Pure Protect lock. To guarantee that the purified drinking water remains safe and retains its high quality, this mechanism shuts down the filter after it has purified 2000 liters of water. When the mechanism shuts down the filter it is time to replace the filter. See chapter 'Filter replacement'.

- This water purifier conforms to NSF/ANSI 42 for particulates removal (class I) and esthetic chlorine removal, NSF/ANSI 53 for turbidity removal and USEPA Microbiological Guide for bacteria, virus and cyst removal, as verified and substantiated by test data.
