7.3.3.2 Control unit connection
• The "PV" solenoid valve, the "PIS" pressure transducer and the
corresponding cables are factory-installed on the primary vessel.
– Run the cable through the assembly pipe on the rear of the primary
vessel to the control unit.
• Subsequently install the level sensor at the primary vessel,  7.3.5 "Fitting
the level sensor",  33.
– Attach the cable to the "LIS" pressure pick-up of the level sensor and
run the cable to the control unit.
• The flexible compressed air hose is connected with the control unit. Run
the compressed air hose through the assembly pipe as well.
– Control unit with one compressor:
• Connect the compressed air line directly to the "AC"
compressed air connection of the primary vessel.
– Control unit with two compressors or additional secondary vessel:
• First install the supplied distributor at the "AC" compressed air
connection of the primary vessel.
• Connect the compressed air lines of the compressors via the
distributor.
• Use the supplied connection sets to connect the secondary
vessels.
7.3.4 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.

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!

7.3.5 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.
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,  7.3.2
"Tank installation",  32. 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.
– In the case of a vessel volume of 1000 l (Ø 1000 mm) or more, use the
supplied screws to attach the pressure load cell at the vessel base of
the primary vessel.
• Avoid shock-type loading of the pressure load cell by, for example,
subsequent alignment of the vessel.
• Use flexible hoses to connect the primary vessel and the first secondary
vessel.
– Use only the supplied connection sets,  7.3.2 "Tank installation",
 32.
• Perform a null balancing of the filling level when the primary vessel is
aligned and fully emptied,  10.3 "Configuring settings in the controller",
 39.
Standard values for level measurements:
Primary vessel Measuring range
200 l 0 – 4 bar
300 – 500 l 0 – 10 bar
600 – 1000 l 0 – 25 bar
1500 – 2000 l 0 – 60 bar
3000 – 5000 l 0 – 100 bar
7.4 Make-up and degassing variants
7.4.1 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.

3 Reflex Fillset
ST Dirt trap
Preferably, you should use the Reflex Fillset with integrated system separator
when using drinking water for make-up. If you don't use a Reflex Fillset, you
must use an "ST" dirt trap with a mesh size ≥ 0.25 mm for the make-up.
