11.6 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 downstream
device (coffee machine) and to prevent potential damage, it is important to adhere to the maintenance
cycle outlined below.
Maintenance to be performed
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)
11.7 Long Term System Shutdowns
BRITA recommends not to decommission PROGUARD Coffee components for long periods (see chap-
ter 7: Long Term System Shutdowns). In case of extended periods of non-use, call a service technician.

11.8 Troubleshooting
Possible problems with PROGUARD Coffee can be identified at the reverse osmosis unit itself, the
downstream installed coffee machine or the coffee taste. To find out more about the potential causes
of the detected or perceived fault, check if the issue is listed in the error directory of chapter 9.1: Errors,
Root Causes and Measures For The Service Technician. Call and consult a service technician. Keep
in mind that defects may only be solved by specialist staff with an understanding of local and
regional regulations/codes that may affect the installation and re-installation requirements.
