Installation
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.
The following typical example describes the installation of the primary vessel
with the attached control unit and the connection of two secondary vessels.
Proceed accordingly for other installation variants.
1 Expansion pipe
2 Compressed air line
3 Data line
RF Secondary vessel
RG Primary vessel
6.3.3.1 Water-side connection
To ensure the proper function of the "LIS" level sensor, you must use the
supplied hose to flexibly connect the primary vessel to the system.
The "EC" expansion line provides secure locking and emptying for primary vessel
and the optional secondary vessels. If more than one vessel is used, a collective
line to the system is installed.
Use points with temperatures between 0 °C and 70 °C to connect to the system.
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 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.

6.3.3.2 Control unit connection
• The "PV" solenoid valve, the "PIS" pressure transducer and the
corresponding cables are factory-installed on the primary vessel.
• The cables between the primary vessel and the control unit are pre-
installed.
Subsequently install the level sensor at the primary vessel,  6.3.5 "Fitting
•
the level sensor",  24.
– The cable must be run through the assembly pipe on the rear of the
primary vessel if it has not been pre-installed.
• The flexible compressed air hose is connected with the control unit. Run
the compressed air hose through the assembly pipe as well.
– If you install only the primary vessel, you must connect the
compressed air hose directly to the "AC" compressed air connection
of the primary vessel.
– If you install secondary vessels, you install first the supplied
distributor at the compressed air connection of the primary vessel.
• Use the supplied connection sets to connect the secondary
vessels.
6.3.4 Connection to an external compressed air line
An external pressure supply can optionally be connected to the Reflexomat.
When doing so it must be ensured that a pressure reducer is fitted in the external
pressure line. The minimum pressure to be set depends on the relevant pressure
rating of the vessel.
1 Pressure reducer, site attachment
2 Dirt trap, site attachment
3 Pressure gauge, site attachment
4 Solenoid valve, supplied by Reflex
Instead of the compressor, a solenoid valve is actuated in the external
compressed air line, which releases the compressed air for the vessel. The
solenoid valve is activated by the controller. The electrical connection of the
solenoid valve is made via the terminal for the compressor in the respective
controller.
Properties of the external compressed air:
• Quality
– Fluid group 2 according to the Pressure Equipment Directive 2014 /
68 EU.
– DIN ISO 8573-1 Class 1.
• Oil-free
– ATTENTION Diaphragm damage caused by oil-containing
compressed air. Keep the compressed air free of oil.
• Compressed air
– ATTENTION Damage to the vessel. The compressed air must be
reduced to the respective vessel pressure rating.
 Note!
See chapter "Terminal plan" for the solenoid valve electrical connection.
6.3.5 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.
