Intended use
01/21 FlowTimer+ Set 8
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
01/21 FlowTimer+ Set 10
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.

4 Basic safety instructions
WARNING
Electrical voltage can be life-threatening.
The installation of a fixed power supply must be carried
out by a qualified electrician.
Commissioning and possible adjustment of the system must
be carried out by a specialist. The local conditions must be
observed.
The FlowTimer+ system may only be installed in the cold
water line.
The measures before installation must be observed (see
also chapter 6.1 "Measures before installation").

6 Installation
The FlowTimer+ must be installed in the piping system by a
trained specialist in accordance with the installation
instructions.
6.1 Measures before installation
The operating pressure must always be between 1 bar and 10
bar. If this is exceeded, a pressure reducer must be installed
upstream of the FlowTimer+ in the direction of flow.
Existing KFR valves, backflow preventers or check valves must
be tested for function and tightness and replaced if necessary.
All consumers must be checked for visible leaks and repaired or
replaced as necessary prior to installation.
If a water heating system with an expansion vessel is installed
downstream of the FlowTimer+ system, this must be checked
(see chapter 8.1)!

Installation
01/21 FlowTimer+ Set 16
6.2 Installation position
The FlowTimer+ is always installed upstream of the pipeline
section and consumer to be monitored.
A backflow preventer or KFR valve must be installed upstream
of each FlowTimer+. Normally this valve is already present
behind the water meter.
However, if several FlowTimer+ are used (like fuses), each
FlowTimer+ requires such a valve.

Installation
01/21 FlowTimer+ Set 18
6.3 Installing the shut-off valve
The shut-off valve (2) can be installed in any position. The
direction of flow (3) must be observed.
It must be possible to open the valve body without difficulty for
maintenance work. The Allen screws on the valve bonnet must
be accessible from the outside.
The selected installation position must allow the control
electronics (6) with solenoid coil (15) to be mounted and
dismounted.
The shut-off valve may only be screwed into the pipeline at the
flange connections using an open-end wrench.
First install the shut-off valve (2) and the pressure sensor
(5)!
Observe the cable lengths and the visibility of the front of
the FlowTimer+ when installing the valve and pressure
sensor.
The FlowTimer+ electronics (6) and the plug connections
must not be mechanically stressed (risk of destruction)!
6.3.1 Installation position KFR valve
Fig. 6.3.1: Shut-off valve / KFR installation

Installation
01/21 FlowTimer+ Set 19
In order to protect the solenoid valve from malfunctions
due to contamination, care must be taken during
installation to clean the processed materials carefully;
in particular, it must not be possible for metal chips or
sealing materials to be flushed into the valve interior.
6.3.2 Installation position pressure boosting
The FlowTimer+ system must always be installed downstream of a
booster set (or domestic waterworks) in the direction of flow!
A backflow preventer or KFR valve must be installed
between the booster set and the FlowTimer+.
Fig. 6.3.2: FlowTimer+ and pressure boosting system

Installation
01/21 FlowTimer+ Set 20
6.4 Installation of the pressure sensor
The pressure sensor (5) must be installed downstream of the shut-
off valve (2). This can usually be screwed in directly in place of
existing 1/4 inch vent valves or installed in the pipeline using a T-
piece with a reduced outlet.
Only tighten the pressure sensor (5) with an open-end wrench!
The body of the pressure sensor or the plug area must not
be turned by means of e.g. water pump pliers (danger of
destruction)!
Fig. 6.4.1: Pressure sensor installation after the valve
The pressure sensor (5) can alternatively be installed Downstream
of the house filter and / or pressure regulator (see below).
