6 Maintenance
The PROGUARD Coffee system as a whole, its spare parts as well as its refill-parts is subject of
regular maintenance. In order to ensure the reliable function of the RO as well as the operated down-
stream device (coffee machine) and to prevent potential damage, it is important to adhere to the
maintenance cycle outlined below.
Maintenance to be performed
Replacement of PURITY C filter cartridges
Double-check if the bypass position of the
pre-filter head is set to the recommended
position
Tank pressure (tank needle on manometer,
pre-pressure on tank air valve)
Measure filtrate quality (conductivity,
carbonate hardness)
Check for leaks and kinks (hoses, tubes,
adapters)
Replacement of storage tank
Replacement of non-electric pump
Tank pressure
• Check if the manometer's pressure
needle is positioned in the green area
• The pressure gauge must not display
a value above 2.8 bar. If so, call a service
technician for recalibration or exchange
of the manometer to ensure staying in the
Pressure Equipment Directive
• If the pressure gauge displays a value of
1.3 – 1.7 bar, this indicates a high filtrate
demand. Check again later, preferably
not during peak usage times. Call service
technician if the pressure needle is still
within this range or very often in this range
• If the pressure gauge displays a value
of <1.3 bar, call a service technician
Explanations and measures for deviations
from the normal range are given in chapter
9.1: Errors, Root Causes and Measures For
The Service Technician.
Check for a regular click-sound of the
non-electric pump (preferably after the
withdrawal of filtrate)
7 Long Term System Shutdowns
BRITA recommends not to decommission PROGUARD Coffee components for long periods. During
extended periods of non-use, turn off the water supply to the unit and remove the PURITY C filter
cartridges. When restarting the unit, the cartridges are to be reinstalled and flushed per instructions.
The entire PROGUARD Coffee system is to be flushed thoroughly as well (see chapter 5.2: Installa-
tion and Putting The System Into Operation).
