If the fluidic part of the unit shows a fault due to wear, this is
indicated by means of the control electronics by an error case
from the entire system (incl. downstream piping system).

Intended use

3 Intended use
Please observe the instructions in these operating instructions as
well as the operating conditions and permissible data in
accordance with the data sheet so that the system functions
properly and remains operational for a long time. In case of non-
observance of these instructions as well as in case of unauthorized
interventions in the system, any liability on our part is void, as well
as the warranty on system and accessories!
The FlowTimer+ is used for permanent monitoring of piping
systems for drinking water (see also chapter 2"Technical data ").
The aim is to prevent a permanent flow of water without interruption
after a previously set duration and size, and thus to achieve
damage limitation by minimizing the amount of water flowing out.
In addition and simultaneously, the entire system is permanently
tested for overall tightness over several hours. This is performed
independently of the user settings (see above) and consumer
behavior. A system that is not tight for several hours is indicated by
a yellow status display.
Any other use or use that goes beyond this is considered improper
use. Usetech GmbH is not liable for any damage resulting from this.
The risk is borne solely by the user.

Intended use
01/21 FlowTimer+ Set 9
3.1 Use not in accordance with the intended purpose
Unintended use in the sense of foreseeable misuse is considered
to be:
It must be checked whether the existing installation allows
FlowTimer+ to function smoothly at all, e.g. permanent
consumers, etc.
The FlowTimer+ may only be operated with the components in
the set or in combination with other FlowTimer+ products, unless
explicitly stated otherwise! If components of othermanufacturers
are used, usetech GmbH is not liable for damages and the
warranty is also void.
FlowTimer+ was designed exclusively for drinking water. The
system is not suitable for rainwater, other liquids or gases.
FlowTimer+ is not suitable for use within the hot water
preparation or heating installation!

Intended use

3.2 Main differences from PPC 3000 Basic
The FlowTimer+ no longer shuts off if the system is not tight
(observed over hours), but only displays this for convenience!
The shut-off valve of the FlowTimer+ is open without power! Thus,
the water supply can be comfortably restored only by switching off
the power supply if required or during a power failure. An active
bypass mode is therefore no longer included.
The FlowTimer+ can also be installed upstream of the filter or
backwash filter because of an integrated filter system.
A configuration of the system is no longer necessary in most
applications, which means that the system is immediately ready for
operation after proper installation!
The maximum permanent flow duration and sensitivity can be
adjusted to personal needs very easily at the touch of a button.
A test mode is also available to assist the customer or installer in
troubleshooting a possible leak.
