Important

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

Warning

• This appliance 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 appliance by a person responsible for their safety.
• Children should be supervised to ensure that they do not play with the appliance.

Before 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.
• Let the water run at the filtered setting for 10 seconds before the first use of the day.
• 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.
• 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 50^ C run through the water purifier, because this may damage the appliance.
• Do not let the water purifier freeze.

Battery

To prevent that the battery leaks, overheats or explodes:

• Do not disassemble the battery.
• Do not charge the battery.
• Do not use a damaged battery.
• Do not expose the battery to water or high humidity levels.
• Do not expose the battery to direct sunlight, high temperatures or fire.

ENGLISH8

- Any liquid leaking from the battery is harmful to eyes and skin. Avoid eye and skin contact.

Applications

• Only use the appliance to filter water that meets drinking water standards at the point of use.
• 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.
• Do not remove the filter cartridge while you use water purifier.
• Do not use the water purifier without a filter cartridge.
• Do not place the appliance near a window where it is exposed to direct sunlight.
• This appliance does not soften water.
• Do not use filtered water in aquariums. Tap water, filtered or unfiltered, can be harmful to fish.
• 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.

• The LCD display on the water purifier shows the current remaining filter capacity. A remaining filter capacity of 0 tells you that you have to replace the filter. Philips' unique cartridge replacement indicator also helps you to determine when to replace the filter.
• The high-speed initial flow rate of 2 litres per minute gives you 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 nine 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

Inserting the battery

• Before you insert the battery, make sure your hands and the water purifier are dry.
• Keep away from the kitchen sink to prevent the battery from falling down the drain.
• Insert the battery before you install the water purifier on the tap.

1 Use a coin to turn the battery compartment cover on the back of the water purifier in the 'OPEN' direction. Remove the battery compartment cover (Fig. 2).

2 Place the battery (included) in the cover, with the + pole facing the battery compartment cover (Fig. 3).

3 Place the battery compartment cover back onto the water purifier in such a way that the ‘▲’ mark on the cover is aligned with the ‘I’ mark on the water purifier. (Fig. 4)

4 Use a coin to turn the battery cover in the 'CLOSE' direction until the 'I' mark on the cover is aligned with the 'I' mark on the water purifier (Fig. 5).

ENGLISH10

Note: Make sure you align the 'I' marks properly, otherwise water may leak into the battery compartment.

When the battery is properly inserted, the LCD display performs a self-check for approx. 9 seconds. Then the display goes off again.

Before installation

The screw thread of the tap is sharp.

• 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 0.7kgf/cm ^2 (7 metres of water column) and 3.5kgf/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. 6).

1 Remove the attachment nut and the adapter from the water purifier housing (Fig. 7).

2 Pass the attachment nut over the tap spout (Fig. 8).

3 Place the matching adapter (A-type) over the tip of the spout. The 16mm adapter is packed with the water purifier. If necessary, replace it with the 17.5mm adapter or 19mm adapter to fit the diameter of your tap (Fig. 9).

4 Screw the attachment nut firmly onto the water purifier housing (Fig. 10).

Installation B-type adapter

- For taps with an aerator (threaded on the outside) (Fig. 11).

1 Remove the attachment nut and the adapter from the water purifier (Fig. 7).
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. 12).
3 Tighten the adapter further with a coin (Fig. 13).
4 Firmly screw the attachment nut onto the water purifier housing (Fig. 14).

Installation C-type adapter

- For taps with an aerator (threaded on the inside) (Fig. 15).

1 Remove the attachment nut and the adapter from the water purifier housing (Fig. 7).
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. If water leakage occurs, wind Teflon tape round the screw thread of the adapter before you screw it onto the tap (Fig. 16).
3 Tighten the adapter further with a coin (Fig. 17).
4 Firmly screw the attachment nut onto the water purifier housing (Fig. 18).

Installation D-type adapter

- For taps other than A, B or C. (Fig. 19)

1 Remove the attachment nut and the adapter from the water purifier housing (Fig. 7).
2 Take out the original adapter and screw the D-type adapter onto the water purifier housing. (Fig. 20)
3 Push the water purifier housing onto the tap from below and tighten the 4 screws evenly (Fig. 21).

ENGLISH12

4 Screw the attachment nut firmly onto the water purifier housing (Fig. 22).

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.

3 Tilt the filter cartridge 90° backwards and insert it into the water purifier housing. (Fig. 24)
4 Pull the cartridge upwards until it is in upright position. (Fig. 25)
5 Air trapped inside the filter cartridge affects the flow rate of the filtered water. To avoid this, slightly open the tap and let water run through the filter cartridge for 30 seconds after you install/replace the filter cartridge. The slow stream of water helps to remove any air trapped in the filter.

Setting the filter capacity

The default filter capacity setting of the water purifier is 1500 litres. Follow the instructions below to set the filter capacity of your filter cartridge. The capacity of the filter cartridge supplied with the WP3821 is 2500 litres.

Note: When you replace the filter cartridge for the first time and any next time, reset the filter capacity as described in section ‘How to reset the filter capacity’ in chapter ‘Replacement’.

1 Make sure that the water purifier housing and the filter cartridge are properly installed.

2 Press the filter capacity selection button.

The default filter capacity of 1500 litres flashes on the display for 4 seconds.

3 Press the filter capacity selection button again until the display shows the capacity of your filter cartridge (1500-2500-900-1500 etc.).
4 Stop pressing the filter capacity selection button when the display shows 2500 litres.
The selected filter capacity and the remaining filter capacity are shown for 5 seconds.

Using the appliance

1 Turn the water selection lever to the desired setting ('click'). The water selection level has 3 settings: filtered spray, unfiltered spray and unfiltered stream. See the sections below.
2 Open the tap.

Filtered spray

Select this setting for drinking, washing vegetables or fruits and for cooking.

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

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.

2 Open the tap.

• Filtered spray comes out of the water purifier.
  The display is on and counts down the remaining filter capacity.

Note: The LCD display only shows the remaining filter capacity when you use the water purifier at the filtered spray setting and when the water pressure is more than the minimum required 0.7 kgf/cm^2 (7 meters of water column).

Note: The display is off when you do not use the water purifier and when you use it at the unfiltered spray and unfiltered stream settings.

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. 27).

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

Unfiltered stream

Select this setting for a strong water flow.

1 Turn the water selection lever until the unfiltered stream symbol is aligned with the indicator (Fig. 23).

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

Cleaning

Never use scouring pads, detergents, abrasive cleaning agents or aggressive liquids such as thinner, alcohol, petrol or acetone to clean the appliance. These substances may cause cracking, discolouration or distortion.

2 Clean the appliance with a moist cloth.

Note: Do not use a brush to clean the display.

3 Regularly clean the stainless steel screen and the unfiltered water inlet under a running tap with a clean and soft brush.

Replacement

Replacing the filter cartridge

New filter cartridges are available under type number WP3911.

Replace the filter cartridge if it is clogged to prevent damage to the water purifier.

No part of the cartridge can be reused. Discard the used cartridge and replace it with a new one.

When to replace the filter cartridge

The actual lifetime of the filter cartridge depends on the quality of the local water and the water pressure. For optimal performance of the water purifier, replace the filter cartridge if one of the following situations occurs:

• The display shows that the remaining filter capacity is 0 litres and keeps flashing.
• The hollow fibre of the filter cartridge (visible through the cartridge window) has turned rust brown or dark grey (see section ‘Cartridge replacement indicator’).
• You have used the filter cartridge for 6 months.
• The volume of purified water decreases substantially.
• The filtered water still has an unpleasant smell or is still turbid after purification.

Cartridge replacement indicator

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. 28).

ENGLISH16

Reduced filter cartridge life

The filter cartridge has a shorter life and should be replaced more frequently in the following situations:

• The water pressure is very low.
• The pipes and water tank are worn.
• The tap water is contaminated due to plumbing activities or cleaning of the water tank.
• When you use cloudy water immediately after heavy rain.

How to replace the filter cartridge

1 To replace the filter cartridge, close the tap and set the water selection lever to the unfiltered stream setting. (Fig. 23)
2 Tilt the used filter cartridge 90^ backwards and pull it off the water purifier housing (Fig. 24).
3 Write down the replacement date on the information label of the new cartridge.
4 Tilt the new filter cartridge 90° backwards and insert it into the water purifier housing.

5 Pull the cartridge upwards until it is in upright position. (Fig. 25)

6 Reset the remaining filter capacity indication, even if it has not yet reached 0.

• Press the reset button for 2 seconds. The previously selected filter capacity flashes on the display.
• If the new filter cartridge has the same capacity, simply wait until the setting stops flashing.
• If the new filter has a different capacity, press the filter capacity selection button and keep it pressed until the display shows the new filter capacity. Then release the button and wait until the new setting stops flashing.

7 The water purifier starts counting down the remaining filter capacity as soon as you use the water purifier at the filtered spray setting.

How to reset the filter capacity

Note: Always reset the filter capacity when you replace the filter cartridge. This is necessary to set the remaining filter capacity back to its initial value (i.e. 2500, 1500 or 900 litres).

1 Press the reset button for 2 seconds
2 Press the filter capacity selection button.
The set filter capacity flashes on the display for 4 seconds.
3 If the new filter cartridge has the same capacity as the old cartridge, simply wait until the setting stops flashing.
4 If the new filter has a different capacity, press the filter capacity selection button again until the display shows the capacity of your filter cartridge (1500-2500-900-1500 etc.).
5 Stop pressing the filter capacity selection button when the display shows the capacity of the new filter cartridge.
The selected filter capacity and the remaining filter capacity are shown for 5 seconds.

Replacing the battery

The battery lasts approximately one year in case of normal domestic use. Replace the battery when the ☐ symbol lights up and flashes. This appliance runs on 1 button-type CR2032 (3V) lithium battery, which is generally available.

1 Remove the water purifier from the tap.
2 Wipe the entire water purifier with a dry cloth.
3 Place the new battery (see ‘Inserting the battery’ in chapter ‘Preparing for use’).
4 Reattach the water purifier to the tap (see the installation instructions for your adapter type in chapter ‘Preparing for use’).

Note: When you replace the battery, the water purifier remembers the remaining filter capacity. If no battery is inserted in the water purifier, the remaining filter capacity is not counted down.
