Installation Requirements - Brita PROGUARD Coffee Mode D'emploi

Manometer
Measures the pressure of the storage tank bladder. The pressure needle must lie within the
specified parameter of 1.7–2.8 bar to ensure the flawless supply of filtrate. Explanations and
measures for deviations from the normal range are given in chapter 9.1: Errors, Root Causes
and Measures For The Service Technician.
Valve for the automatic bypass
Ensures sufficient feed water to run the coffee machine at any time. The valve for the automatic
bypass is installed after the pre-filter and opens automatically if the tank has run empty and the
coffee machine's current water (filtrate) demand exceeds the filtrate production rate of PROGUARD
Coffee. The valve must never be turned off during operation of PROGUARD Coffee.

The minimum required inlet pressure is 3 bar. If 3 bar cannot be met by
the local mains water supply, an electric booster pump must be installed
in front of PROGUARD Coffee. For more information see chapter 5.3:
Specification and Installation of an Electric Booster Pump.
Regardless of the level of the mains water supply pressure, an electric
booster pump can be installed to increase the filtrate production rate of
PROGUARD Coffee (litres/hour; see chapter 3.2 Role and Functionality of
The Main Components of PROGUARD Coffee, Pump [non-electric])
The maximum inlet pressure must not exceed 8.6 bar. The maximum
pressure the RO can be operated with is 6 bar. A pre-installed pressure
reducer reduces the inlet pressure to the maximum permissible operating
pressure of 6 bar.
The minimum filtrate outlet pressure provided by PROGUARD Coffee is
1.3 bar. Make sure that the spatial distance (distance, height difference)
between PROGUARD Coffee and the coffee machine is not too large in
order to keep the resulting pressure loss as low as possible.
The maximum filtrate outlet pressure provided by PROGUARD Coffee
is 2.7 bar.
