Connection to the facility system

CAUTION
Risk of injury due to falls or stumbling
Bruising caused by falls or stumbling over cables or pipes during installation.
• Wear personal protective equipment (helmet, protective clothing,
gloves, safety boots).
• Ensure proper installation of cables and pipes between the control unit
and the vessels.
ATTENTION
Damage due to improper installation
Additional device stresses may arise due to the connection of pipes or system
equipment.
• Ensure that pipes are connected from the device to the system without
them being stressed or strained.
• If necessary, provide support structures for the pipes or equipment.
ATTENTION
Damage to cables and pipes
If cables and pipes are not routed professionally between tanks and the
control unit, they may become damaged.
• Route cables and pipes in a professional manner over the flooring.
6.3.2.1 Water-side connection
1 Expansion pipe
2 Compressed air line
3 Data line
RG Primary vessel
LIS Level sensor
To ensure the proper functioning of the "LIS" level sensor, you must use the
supplied hose to flexibly connect the primary vessel to the system circuit.
The primary vessel has a protected shut-off device and a drain in the "EC"
expansion line.
Use points with temperatures between 0 °C and 70 °C to connect to the system
circuit. This is the return of the generator in heating systems and the flow in
refrigeration systems.
At temperatures below or above 0 °C – 70 °C, you must install in-line vessels
between the system circuit and the Reflexomat.

Note!
For details regarding the switching of Reflexomats or in-line vessels and
the dimensions of the expansion lines, please see the planning
documents. More information is also provided in the Reflex Planning
Guide.

Fitting the level sensor

ATTENTION
Damage to the pressure load cell due to unprofessional installation
Incorrect installation may result in damage to the "LIS" level sensor,
malfunctioning and incorrect measurements from the pressure load cell.
• Comply with the instructions regarding the installation of the pressure
load cell.
The "LIS" level sensor uses a pressure load cell. This pressure pick-up is to be
installed after the primary vessel has been placed at its final position, see
chapter 6.3.1 "Locating the vessel" on page 6 . Comply with the following
instructions:
• Remove the transport securing device (squared timber) at the vessel base
of the primary vessel.
• Replace this transport securing device with the pressure load cell.
• Avoid shock-type loading of the pressure load cell by, for example,
subsequent alignment of the vessel.
• Perform a null balancing of the filling level when the primary vessel is
aligned and fully emptied, see chapter 9.2 "Configuring settings in the
controller" on page 12 .
Standard values for level measurements:
Primary vessel
200 l
300 - 500

Function

The filling level is recorded in the primary tank by the "LIS" level sensor and
evaluated in the controller. When the water level falls below the value specified
in the controller's customer menu, the external make-up is activated.
