Important

Read this user manual carefully before you use the water purifier and save it for future reference.

Warning

- This water purifier is not intended for use by persons (including children) with reduced physical, sensory or mental capabilities, or lack of experience and knowledge, unless they have been given

supervision or instruction concerning use of the water purifier by a person responsible for their safety.

- Children should be supervised to ensure that they do not play with the water purifier.

Before daily use

• To prevent quick clogging of the filter cartridge, let the water run at the unfiltered setting for around 5 seconds before every use.
• If the water is highly coloured or turbid due to work on your water network, do not let the water run at the filtered setting until the water is clear.
• Cautions:

1 Let the water run at the filtered setting for 10 seconds before use each day.
2 Let the water run at the filtered setting for 60 seconds before use if you have not used the water purifier for more than two days.
3 If you have not used the water purifier for more than two weeks, let the water run at the filtered setting for 2-3 minutes before use. If the filter cartridge emits an unpleasant smell, replace it with a new one.

Water temperature

• Do not let water hotter than 65^ C run through the water purifier at the unfiltered setting or hotter than 50^ C at the filtered setting.
  This may damage the water purifier.
• Do not let the water purifier freeze.

Applications

• Only use the water purifier to filter water that meets drinking water standards.
• Do not use this water purifier in combination with electric taps.
• Do not block the filtered water outlet or connect other devices to it.
• If the water pressure is very high, reduce the water flow of the tap to prevent damage to the cartridge.
• Keep the water purifier away from heat to avoid distortion or breakage.
• Do not tamper with the water purifier.

ENGLISH8

• Do not remove the filter cartridge while you use the water purifier.
• Do not install the water purifier near a window where it is exposed to direct sunlight.
• Do not use the water purifier without a filter cartridge.
• This water purifier does not soften water.
• Do not use filtered water in aquariums. Tap water, filtered or unfiltered, can be harmful to fish.
• This water purifier is intended for household use only.
• Do not store purified water to avoid contamination. Air contact contaminates purified water quickly. If you want to store purified water, use a clean container and keep it in the refrigerator. Do not keep it in the refrigerator longer than 1 day to avoid contamination.

Features

• Philips' multi-filtration system consists of a primary filter, a secondary filter, a high-tech hollow-fibre membrane filter and a granular activated carbon filter.
• The hollow fibre membrane contains more than 520 billion micropores that are small enough to remove particles down to 0.1μm. It eliminates 99.99%* of bacteria, rust and other particles larger than the micropore size from your tap water without removing calcium, magnesium and other minerals that are vital to your body. (* tested according to Japanese Water Purifier Association (JWPA) standard).
• The granular activated carbon removes the unpleasant chlorine smell and taste from your tap water.
• Apart from the recommended cartridge lifetime, Philips' unique cartridge replacement indicator helps you determine when to replace the filter cartridge.
• The 2ltrs/min high-speed initial flow rate gives you a plenty of clean water instantly.
• The water selection lever offers you a choice of three water flow types: unfiltered spray, unfiltered stream or filtered spray.
• The eight tap-mounting adapters supplied with the water purifier allow easy installation on almost any type of tap.

- The bayonet-type mount ensures quick, easy and secure filter cartridge replacement.

Preparing for use

Before installation

• Before you install the water purifier, make sure all tap-mounting adapters you require are present.
• The tap must have a diameter of 13mm-25mm.
• Determine what type of tap you have and select the appropriate adapter.
• The adapters supplied make the water purifier suitable for almost any kitchen tap. However, the water purifier may not fit some uncommon types of taps.
• The tap water pressure has to be between 0.3 kgf/cm^2 (3 metres of water column) and 3.5 kgf/cm^2 (35 metres of water column). If you use the water purifier at a water pressure outside this range, either the filtered water flow will be extremely low or the water purifier will get damaged.

Installation A-type adapter

- For taps with a round spout with a diameter of 16mm, 17.5mm or 19mm (Fig. 2).

1 Remove the attachment nut and the adapter from the water purifier housing (Fig. 3).
2 Pass the attachment nut over the tap spout (Fig. 4).
3 Place the matching adapter (A-type) over the tip of the spout. The 16mm adapter is packed with the water purifier. Replace it with the 17.5mm adapter or 19mm adapter to fit the diameter of your tap (Fig. 5).
4 Screw the attachment nut firmly onto the water purifier housing (Fig. 6).

Installation B-type adapter

- For taps with an aerator (threaded outside) (Fig. 7).

ENGLISH10

1 Remove the attachment nut and the adapter from the water purifier (Fig. 8).
2 Remove the aerator cap from the tap and pass the attachment nut over the spout. Take out the original adapter and screw the matching adapter (B-type) onto the tap (Fig. 9).
3 Tighten the adapter further with a coin (Fig. 10).
4 Firmly screw the attachment nut onto the water purifier housing (Fig. 11).

Installation C-type adapter

- For taps with an aerator (threaded inside) (Fig. 12).

1 Remove the attachment nut and the adapter from the water purifier housing (Fig. 13).
2 Remove the aerator cap from the tap. Take out the original adapter and screw the matching adapter (C-type) onto the tap through the attachment nut. (Fig. 14)

3 Push the water purifier housing onto the tap from below and tighten the 4 screws evenly (Fig. 20).
4 Screw the attachment nut firmly onto the water purifier housing (Fig. 21).

Make sure the rubber washer is firmly pushed against the tap to prevent water leakage.

Installing the filter cartridge

1 Make sure the tap is closed.

Do not let water hotter than 50^ C run through the water purifier at this setting, as this may damage the water purifier.

If you filter water between 35^ C and 50^ C, the water may have an unpleasant smell. The filter cartridge has absorbed this smell during filtering, but releases it again if you filter water hotter than 35^ C.

Unfiltered spray

Select this setting for washing dishes and other jobs that require a gentle water flow.

1 Turn the water selection lever until the unfiltered spray symbol is aligned with the indicator (Fig. 26).

Cartridge replacement indicator

• We advise you to replace the filter cartridge every 6 months, for optimum performance. Please register your product online at http://www.philips.com/welcome for more information on filter cartridge replacement.
• To help you determine when to replace the filter cartridge, the water purifier and each replacement filter cartridge comes with a self-adhesive colour-coded cartridge replacement indicator. Place this replacement indicator in a convenient place for future reference.

Tip: Remove the cover of the filter cartridge and stick the cartridge replacement indicator to the inside of the cover. Check the colour of the hollow fibre of the filter cartridge through the cartridge window from time to time. If the colour of the filter matches the rust brown or dark grey shown on the cartridge replacement indicator, replace the filter cartridge (Fig. 27).
