Installation
7.3.6 Installation of the weight measuring cell
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 measurement uses a pressure load cell. This pressure load cell is
to be installed after the primary vessel has been placed at its final position,
 7.3.3 "Tank installation",  39. Comply with the following instructions:
•
Remove the transport safety device (squared timber) at the mounting foot of
the primary vessel.
•
Replace this transport safety device with the pressure load cell.
–
The pressure load cell can optionally be fastened to the mounting foot
of the primary vessel using the supplied screws. However, fastening is
not necessary.
•
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,  7.3.3 "Tank installation",
 39.
•
Perform a calibration of the filling level when the primary vessel is aligned
and fully emptied,  8.6 "Parametrising the controller in the Customer
menu",  47.
Standard values for level measurements:
Primary vessel Measuring range
0 – 4 bar
200 l
300 – 500 l 0 – 10 bar
600 – 1000 l 0 – 25 bar
1500 – 2000 l 0 – 60 bar
3000 – 5000 l 0 – 100 bar

Note!
The weight measuring cell is not resistant to water hammer; also it must
not be painted!
7.4 Switching and make-up variants
7.4.1 Function
The current filling level is recorded in the primary tank by the "LIS" level sensor
and evaluated in the controller. The value for the minimum filling level is specified
in the controller's Customer menu. If the level drops below the defined minimum,
the "WV" make-up valve opens and fills the primary tank.

Note!
To complete the make-up function from the drinking water system, Reflex
offers the Fillset with integrated system separator and Fillsoft softening
equipment,  4.6 "Optional equipment and accessories",  34.

LIS Level sensor
Single boiler system ≤ 350 kW, water temperature < 100 °C.
•
Connect the Reflex Fillset with integrated system separator upstream when
using mains water for make-up.
•
If you don't connect a Reflex Fillset upstream, use an "ST" dirt trap with a
mesh size ≥ 0.25 mm for the make-up.

Note!
The quality of the make-up water must comply with the applicable
standards such as VDI 2035.
–
If you cannot achieve this quality, use the Reflex Fillsoft to soften
the make-up water from the mains water network.
