General Information

Function and Application PURITY Quell ST

The BRITA PURITY Quell ST Water Filter System is used for decarbonisation of drinking water to prevent limescale deposits in downstream appliances. Depending on the by-pass setting, calcium, magnesium and metal ions can be selectively removed from the drinking water during the flow process. Furthermore, the filter material reduces cloudiness and organic impurities, as well as contents which affect taste and odour (e.g. chlorine residues) in the filtrate and bypass water. By-pass settings on the connector head are used to set the total hardness reduction to the local water hardness or the requirements of the application in order to achieve an optimum water quality. The filter systems are available in 3 different filter system sizes (PURITY 450, PURITY 600 and PURITY 1200) and each in the version without integrated measuring and display electronics or with measuring and display (Advanced Control System, ACS-Technology) electronics.
Filter systems with ACS Technology show you the current remaining capacity and bypass setting of your filter cartridge, the set type and size of the filter system and the last replacement date of the filter cartridge. This ensures optimum filter control and water filtrate quality. Further information on the filter system with ACS Technology.
The unique IntelliBypass ensures a constant by-pass proportion over the entire usage periods, irrespective of the volumetric flow of the terminal device concerned. The result is a consistently high water quality specifically tailored to the application-specific requirements and the local water conditions.
Typical applications for BRITA PURITY Quell ST water filter systems are coffee and espresso machines, hot and cold drinks vending machines as well as steam ovens (combi ovens) and air humidifiers.
The filter system is designed for limited spaces, especially in drinks machines and kitchen installations and can be operated horizontally and vertically.
The food quality of BRITA water filter products has been inspected and confirmed by an independent institute.

Specific Safety Information

• Only water of drinking water quality may be used as intake water for the BRITA water filter system. The BRITA water filter system is only suitable for cold water use within the water intake temperature. No microbiologically impaired water or water of unknown quality may be used without appropriate disinfection.
• If there are official instructions to boil tap water, BRITA filtered water must also be boiled. When the requirement to boil water comes to an end, the filter cartridge must be replaced and the connections cleaned.
• It is generally recommended to boil tap water for certain groups of people (e.g. people with weakened immune systems, babies). This also applies to filtered water.
• Note for people with kidney disease or dialysis patients: during the filter process, the potassium content may be increased slightly. If you suffer from kidney disease and/or have to stick to a special potassium diet, we recommend prior agreement with your doctor.
• The water filtrate is classified in Category 2 according to DIN EN 1717.
• BRITA recommends that the filter system not be decommissioned for a long period. If the BRITA filter system is not used for several days (2–3 days), we recommend that the PURITY Quell filter system be flushed with at least x* litres according to the table below. After stagnation periods of over 4 weeks, the filter should be flushed with at least x** litres (see table below) or else replaced. Please also note that the maximum usage period of the filter cartridge is 12 months.

• The filter system is not resistant to heavily concentrated cleaning agents (e.g. bleach, chlorinated solvents, heavy oxidants) and must not come into contact with them.
• The filter system must not be opened or dismantled during operation. The filter cartridge must not be opened.
• The pressure vessel and the pressure vessel lid of the filter systems have a service life of up to ten years (from the date of installation), provided that they are installed and used correctly and the operating conditions outlined in the Technical Data chapter are adhered to. They must always be replaced after a maximum of ten years. The hoses must be replaced in rotation after a maximum of five years.

Safety Assembly Instructions

• The terminal device operated with the filter must be free of limescale prior to installation.
• The filter system can also be operated downstream of water softening systems.
• Protect the filter system from sunlight and mechanical damage. Do not assemble near sources of heat and open flames.
• A stop valve must be installed before the filter system intake hose.
• If the water pressure is higher than 6.9 bar or if there are statutory requirements, a pressure reducer must be installed before the filter system.
• A non-return valve according to DIN EN 13959 tested by the DVGW has been factory installed at the water intake of the filter head.
• When choosing the material for parts that come into contact with water after the BRITA filter system, it is important to remember that, due to the process, decarbonised water contains free carbon dioxide. For this reason, only materials that are compatible with free carbon dioxide must be used. We recommend the use of BRITA hoses.
• All parts must be installed in accordance with the country-specific guidelines on the installation of drinking water facilities.

Installation

Prior to installation, read the Technical Data and the Operating and Safety Information. After the product has been stored and transported at temperatures below 0°C, it must be stored with the original packaging open for at least 24 hours before commissioning.

Delivery Scope

To install a PURITY Quell new filter, you need a pressure vessel , filter cartridge and pressure vessel lid .
Before installing, remove everything included in the delivery from the packaging and check that everything is present:
1 x Pressure Vessel
1 x Pressure Vessel Lid
1 x Filter Cartridge
1 x Manual
1 x Carbonate hardness test or total hardness test
If anything is missing, please contact your local BRITA Office.

Assembling the Pressure Vessel and the Pressure Vessel Lid

• Stand with both feet on the kick loops.
• Lift the pressure vessel and turn it clockwise until the mantle handles are over the kick loops .
• Remove the transport protective cap from the filter cartridge.
• Check that the O-ring seal of the filter cartridge is correctly seated in the groove and also check for dirt and damage.
  Note: the cartridge seat has been lubricated with food-safe lubricant at the factory.
• Stand on the kick loops with both feet and place the pressure vessel lid on the pressure vessel . The position of the arrow marking on the lid h andle 20 must match the "INSERT" groove.
• Press the pressure vessel lid down and turn clockwise until the lock engages.

Assembly of Inlet and Outlet Hoses

Note: The inlet and outlet hoses are not included in the standard scope of delivery. The use of BRITA hose sets is recommended.

• Fit inlet hose at the inlet of the connector head and outlet hose at the outlet of the connector head .
  Note: Inlet "IN" and outlet "OUT" of the connector head are equipped with O-rings as seals, therefore no additional flat seals may be used here. Check that the O-rings are seated correctly.

The max. tightening torque at the 1" and 3/4" connections must not exceed 15 Nm! Only hose connections with flat seals may be used. Hoses with conical screwed connections damage the filter head connections and invalidate any guarantee claims. Only hoses that comply with DVGW-W 543 may be used to connect the device.
Before assembly, note the direction of flow on the upper side of the filter head, "IN" = water inlet, "OUT" = water outlet. Prior to installation, note installation dimensions and operating position. If no original hoses are used, the 1"–3/4" adapter supplied must be used to ensure the return valve is sealed correctly (pre-fitted in the water inlet).

Commissioning a New Filter

By-pass setting for filter systems without and with measuring and display unit

• For PURITY Quell ST filter systems: identify the local carbonate hardness in degrees of German hardness °dH (BRITA nomenclature °KH) using the enclosed carbonate hardness test.
• Check the by-pass setting on the by-pass adjuster.
  Note: A 30% by-pass setting has been made in the factory, and might be changed to suit the local carbonate hardness or total hardness and the application.

Commissioning the filter systems with measuring and display unit

Representation in operating mode

Carbonate hardness
The units of carbonate hardness or total hardness can be set as required to German °dH (= display setting °KH, °DH), English (°e = Clark) (= display setting °EH), French (°f) (= display setting °FH), American (grains per gallon) (= display setting gpg) or international hardness values (mg/l CaCO₃) (= display setting mg/L).
If the setting for the type of hardness (= unit) is changed while the filter is operating, the values that were set originally are converted automatically.

Bar chart
Representation of the remaining capacity using bar charts. After installation of a new filter system or after a filter change, the symbolised filter cartridge is completely filled with 10 bars.

Bypass proportion in percentage
The by-pass proportion is defined as the proportion of decarbonised water in the total amount of filtrate and is indicated as a percentage.

Flow symbol
When water is removed via the filter system, a graphic wave is shown on the display.

Available remaining capacity of the filter cartridge
The remaining capacity of the filter cartridge is shown in litres or in US gallons, depending on which has been selected.
When water is removed, it counts backwards in 1 litre or 1 US gallon stages. If the cartridge is already exhausted, the capacity is indicated as being negative by flashing.
With a remaining capacity of 20% the last two bars in the bar chart start to flash.
With a remaining capacity of 10% the last bar in the bar chart flashes with the two change arrows. From a remaining capacity of 0% the negative bars and the change arrows flash alternately with the remaining capacity shown in negative.

If the monthly limit has been reached up to a month before expiry of the set time limit, it is signalled by the date field flashing.
If the monthly limit is 100% reached, it is signalled by alternate flashing of the date field and the change arrows.
If the remaining capacity and the monthly limit are exceeded, the negative remaining capacity and the date field flash alternately with the change arrows.

Date of the filter commissioning or last filter cartridge change
The date of filter commissioning or last filter cartridge change is indicated as follows:

Selecting the units of measurement
You can choose between European, American and international units of measurement on the display.
For European units of measurement: depending on the type of filter system (STD, STM), select the specified unit of measurement for water hardness °KH, °EH, °FH or ° DH. The unit of v olume and date format are then automatically displayed in litres and DD/MM/YY respectively.
For American units of measurement, select gpg (unit of measurement for water hardness); the unit of volume and the date format are then automatically displayed in US gallons and MM/DD/YY respectively.
For international units of measurement, select mg/L (unit of measurement for water hardness); the unit of volume and the date format are then automatically displayed in litres and DD/MM/YY respectively.

Parameterisation
The following parameters have to be entered:

• Filter system type and size
  STD 4 = PURITY 450 Quell ST
  STD 6 = PURITY 600 Quell ST
  STD 12 = PURITY 1200 Quell ST
