3.5 Technical Safety Assembly Instructions
• The appliance in which the fi lter is used must be free of limescale and gypsum deposits prior
to installation.
• Protect the fi lter system from sunlight and mechanical damage. Do not assemble near
sources of heat and open fl ames.
• A stop valve must be installed before the fi lter system inlet hose.
• If the water pressure is greater than 8.6 bar, a pressure reducer must be installed in front of
the fi lter system.
• When choosing the material for parts that come into contact with water after the BRITA fi lter
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-specifi c guidelines on the installation
of drinking water facilities.
4 Installation
Caution: Prior to installation, read the technical data (Chapter 9) and the operating and safety
!
information (Chapter 3). After storage and transport below 0 °C, the product must be stored in
the open original packaging for at least 24 hours before it is commissioned at the stated ambient
temperatures (Chapter 9) for operation.
4.1 Assembling the fi lter head, water connection
• Close the water intake and switch off the power supply to the end device

the hoses and dimensions of the accessories (e.g. BRITA FlowMeter). When using the
wall mount, install vertically only! The PURITY C1100 Quell ST cannot be installed using
the wall mounting bracket.
• Fit the hoses to the water inlet "IN"
C
• Use fl at seals for G3/8" connections. For John Guest connections, use hoses with a diameter
of 8 mm. In the case of John Guest connections, the two safety clips
after fi tting the hose.
Caution: The tightening torque at G3/8" connections must not exceed 14 Nm!
!
Only hose connections with fl at seals may be used, as hoses with conical screw
connections damage the connections on the fi lter head and invalidate any warranty
claim! We recommend the use of BRITA hoses.
• When using PURITY C 0–70 % fi lter heads, check by-pass setting

factory) and if necessary adjust this setting to the local carbonate hardness (PURITY C
Quell ST) and/or local total hardness (PURITY Finest C) (chapter 4.2).
• Lock the fi lter head
4.2 By-pass setting for and capacity of PURITY C 0–70 % fi lter heads
• Determine the carbonate hardness (for PURITY C Quell ST fi lter cartridges) or total hardness (for
PURITY Finest C fi lter cartridges) of the local water by performing the BRITA carbonate hardness
test or BRITA total hardness test. Alternatively, your local water supplier will be able to provide
information on the local water hardness.
• Determine the by-pass setting and capacity in line with the application and the carbonate and/or
total hardness identifi ed using the by-pass and capacity table (pages 2–6).
• Then turn the by-pass setting
• To ensure precise and continuous control of the degree of fi lter cartridge exhaustion, it is
recommended to install the BRITA FlowMeter 10–100 A.
• Note: With PURITY C AC and PURITY Fresh C fi lter cartridges, all of the intake water is fi ltered.
The fi lter cartridge can be used with fi lter heads that have a variable or fi xed by-pass. The
by-pass that may be set in the fi lter head is not taken into account.
